We here
at Baltic SPA Saunas & Hot Tubs Ltd are as excited as you are at the purchase of your new wood
burning hot tub! The joys of outdoor bathing and relaxation have immense
physical and mental benefits for you and your family. We’ve put together this
document for you, which will outline important safety instructions as well as
maintenance procedures that will ensure you and your family will have a
relaxing and safe experience for years to come!

 

Safety Notes

The
stove is HOT during operations; even more so is the flue; as such 
WHEN
THE STOVE IS ON, DO NOT EVER TOUCH IT.

This is
a wood burning stove and therefore you must never use anything other than wood.
Coal or charcoal used in the stove is likely to damage the system (due to much
higher burning temperatures) and ruin future enjoyment of the wooden hot tub.

Due to
increased heat present in a hot tub, you should NOT use the hot tub if you are
under the influence of Alcohol. This also applies to any other conditions
wherein bathing would be an issue; if you’re unsure you should speak to your
doctor about this.

The
lids for the hot tub should remain on whenever the tub is not in use; as well
you can and should remove the steps to keep children from accessing it.

The
water level in the tub should always be above the HOT water outlet (on external
wood fired heater) while the stove is in use (or above around 2/3rds of the
internal heater).

During
powerful wind storms you should remove the lid and the chimney so that it
cannot be blown off. Alternatively, the lid could be secured with the ratchet
strap if needed.

If you
live in a region that experiences extreme cold, it is likely that your tub
water will freeze. During these times you should drain both the tub and the
external stove completely as expanding ice will 
surely
damage the craftsmanship as well as the heater itself.

Children
should never be left in control of the stove while in use, and should also
NEVER be left unattended either while bathing.

There
is no need to add chemicals to this hot tub: it may affect the wood and/or the
stove. Should you decide to use chemicals, please make sure you’re using the
correct stainless steel grade stove as standard 430 grade is not suitable for
chlorine, bromine and salt water use. This is an all-natural wood burning hot
tub. Please note, the lifespan of the wood can also be compromised if the
chemicals are used as it makes wood softer. 

For
your own safety you shouldn’t bathe alone.

You can
always add cold water to the hot tub if you find the temperature to be too hot
for you.

Hot
Tubs are not the same as a normal baths. 
Water
does not cool as rapidly as it otherwise would due to the firewood
burning. 
For this reason IF YOU
FIND IT TOO HOT, GET OUT
It is
also important to only use your hot tub for shorter periods initially.
Otherwise you are in danger of becoming dizzy and perhaps even fainting.

Where to place your Wooden Hot Tub

NEVER PLACE YOUR WOOD BURNING HOT TUB NEAR
FLAMMABLE OBJECTS

A hot
tub is usually around 200kgs, 
and
significantly heavier when filled your first consideration is going to be on
the ground you set up on
Preferable
to ground, having a concrete pad already constructed and measure would be
ideal. 
It should also be noted that due to this
heavy weight you shouldn’t under any circumstance attempt to move the hot tub
by yourself. In most cases a level stable base either the gravel or paving
slabs is fine but please note the tub will weigh around 2 tonnes once full of
water and people.

Aside
from the ground itself or pad, you will want to assure your site has easy
access to water to make filling the hot tub less of a chore. You will also want
to avoid areas that create a downdraft; to near buildings, or trees, which will
cause some interference with the chimney. You can always check with a stoves
specialist in your area that may be better able to help you with this.

For
ease of emptying the tub, try and allow room for the water to drain. Flower
beds for watering, or a nearby hill make good things to take advantage of in
this instance (assuming the water is not chemically treated).

Installation

The
majority of the time the new tub will arrive completely intact and require no
additional construction. That said you still need to be able to get to your
chosen site. Tubs can be 1 and a half to over 2 meters in diameter and weigh
upwards of 300kg depending on the size and type of wood chosen.

The tub
could be lifted by a group of four to five people and carried into position,
otherwise a crane or tele handler service may be more applicable depending on
your land and where you want to put it.

It is
very important that the 
external
stove
 and the tub are always level to one
another; as they were fitted together during construction this needs to be
maintained. It is vitally important that the upper or HOT hose continues
slightly upwards from the stove and into the tub; otherwise the system will not
function as it should.

Your
stove chimney should fit together simply and only needs to be pressed into
place at the collar of the stove.

Once
you’ve placed your hot tub where you want it; you can begin to fit your
external heater hoses into place; securing them with appropriate jubilee clips
provided. The hoses would ideally need to be straight for a better water
circulation. Elbow shape connections are also available to buy but do not try
to bend the actual hose as this will obstruct the water circulation.

Swelling Up Process

The tub will leak for
the first days until the wood swells up and seals up. Please check / retighten
the straps if the tub was sitting dry for several weeks or so. Spruce can take
up to 7 days and larch up to 12days to swell up / seal up. We normally advise
on leaving the garden hose on at low flow rate just so the bottom has around 2
inches of water and once the bottom swells up in few days, the water will start
going up automatically.
IMPORTANT: On fully wooden tubs you have to keep the water in the tub all the
time so the wood is always in a ‘swollen up stage’. Normally, users just leave
the water after their session and just drain it when their next session is due
and give it a bit of a rinse/ flush with a sponge or even a jet washer if
needed.

Wooden Lid

Please note: the
wooden lid will react to the steam and sun and might get warped eventually
regardless of how well the wood is treated. This will still do the job it’s
meant to do (keep the rubbish away from dropping into the tub) but may lose the
brand new aesthetic look. This is considered as normal wear and tear and will
not be covered under any warranty. We recommend to leave the lids off the tub
until the water cools down which will prolong the life-span of the wooden lid.

If you require an
insulated lid, please contact us, as we have couple companies we can recommend
(Prices start at £399)

Operations

To
begin, simply fill the hot tub with cold water with a garden hose. You can also
collect rainwater if you so desire.

A full
hot tub contains in and around 1800 litres or 1.8 cubic meters of water when
full, different models vary by size/ volume.

Once
you’ve filled the tub, and 
ONLY after
filled can you begin to kindle a fire in the stove; always remove and old ash
from previous use. If you need firelighters they will not harm the stove.

There
is a water-jacket in the firebox of the external stove so always use dry wood
and keep a strong fire burning. The heating of the water can only be managed by
a strong burning fire, so if a weak fire or worse yet wet materials are used
you will end up with more smoke, soot and condensation in the stove, which in
turn can be damaging.

Maintain
heat by feedings the fire as necessary during bathing, make sure to rake embers
as necessary and even them out prior to adding more wood. This cares for the
ease of burning and ensures a strong fire.

Occasionally
you will want to stir the water in the tub. It’s the only way to get an
accurate temperature reading, since hot water rises and cold water sinks; you
want to make sure you mix your tub water well for the most enjoyment out of
your tub.

Check
your pipes regularly to ensure there are no restrictions or clogs of any sorts.
You can do this by simply placing a hand near and inlet or simple visually
check for any sort of heat induced haze in the water that would indicate
circulation.

While
most tubs utilise some form of stainless steel flue, it is bound to become
discoloured through use, somewhat bronzing or becoming gold. This is a nature
effect and is not something that can be changed.

When
initially heating your water, it can take over 3 hours to heat up the tub from
cold; depending on what your outside temperature is. Also factoring into that
time are your fire and wood qualities. You need to be diligent in your fire to
ensure a proper heating of your hot tub.

NOTE: If you continue
to burn in the stove; you are going to continue to heat up your water. While
this seems straightforward it does carry a risk at severely burning occupants,
as well as damaging the equipment. Always check your thermometer to assess
whether the tub is getting too hot for your liking, and stop adding wood to the
stove once it has. Your external heater will also have an air circulation
control on the door which would then need to be shut. Your target temperature
should not exceed 42C degrees. 

ALWAYS allow the fire
to completely go out before you drain the tub.

NEVER DRAIN YOUR TUB WHILE STILL IN USE! –
If you have fired up the stove during this time; the lack of water can
seriously and irreparably damage your heater as well as the tub; there is also
a risk the wooden tub could catch fire.

Maintenance

Wood
fired Hot Tubs don’t require as much maintenance as a modern whirlpool ones.
Clearing ash from the stove before each use is necessary; as well you should
periodically disconnect the chimney (It is modular) and clean any built up
soot. Soot should also be removed from the stove if it builds up. If this isn’t
something you’re comfortable with you can always contact a stove specialist if
necessary.

Ideally
you should change the water in your hot tub after every use; however you can
use it several times across a couple of days, this is more to personal taste.
If you’re going to leave the tub for a time, you should drain, rinse and refill
the tub prior. If you have a fully wooden tub, you should always have the tub
full; unless you have freezing weather in your region; this can seriously
damage the hot tub and the external heater so they both should be drained. Your
external heater also has a separate drain plug at the back.

If this
is your first time filling the tub; you may notice some drips around the
outside of the tub. This is not a defect; but a natural occurrence until the
wood settles into place properly and swells to create a proper seal. The
swelling up process may take around 7 days depending on the wood chosen for
your tub (Larch may take a bit longer). Every few months you should check the
metal bands around the exterior and tighten then if needed. If the stud which
connects the strap looks bent, you should slightly loosen up the strap as it
may snap under extreme tension.

The
tub’s exterior is already treated properly with oils meant to protect it from
UV damage; waterproofing and it will resist fading. We recommend to apply some
wood treatment at least once a year. However over the life of your tub it will
begin to silver; you can continue to maintain it with oils to keep up the
appearance, but you should not use a pressure washer from too close as it can
damage the wood. If you don’t re oil the wood, it will simply age naturally.
Tub can also be painted or varnished to your pleasure as well. 
DO NOT
PAINT, VARNISH OR OIL THE INTERIOR OF THE TUB AS THIS WILL BLOCK THE WATER
ABSORPTION / EXPANSION AND YOU WILL END UP WITH A LEAKING TUB!

 

GENERAL INFORMATION ON HOW TO USE HOT TUBS

BASE & HOT TUB
PREPARATION
A hot tub needs to be placed on a flat, leveled surface (eg.: a wooden decking
or concrete slab). If the hot tub will not be positioned properly on the
surface, tub’s strength, stability, or even aesthetic appearance can be
affected.

Before starting to use
the hot tub, it should be washed/ rinsed thoroughly. The polypropylene
(plastic) or fiberglass tubs can be cleaned using the same chemicals as for the
cleaning pools. Once the tub is clean, it can be filled up with water. Please
make sure the water level is around 10cm from the top before firing it up.

IMPORTANT- If your hot
tub has electrical components (SPA systems, LED lighting, filters, electrical
heating) we recommend to connect the hot tubs electrical system directly from
your fuse box to the circuit breaker (which is on the tub) so no electrical
outlets would be required.

IMPORTANT – To avoid
electrical equipment problems and to secure safety you must make sure the
electrics is earthed.

VERY IMPORTANT– If the
hot tub has electrical heating (single phase), the mains cable needs to be min
2,5m2.

HOT TUB HEATING

IMPORTANT – the fiberglass hot tub heaters heating
temperature can’t go higher than +55C° as higher temperatures can damage the
fiberglass gel coating (will start blistering). Once the hot tub is fired up,
you need to make sure of regular stirring of the water so the hot water doesn’t
concentrate around the heater’s outlet.

HOT TUB WITH INTERNAL
HEATER

When the hot tub is
filled up with water (10cm from the top of the hot tub edge), you can fire up
the heater. The best way to fire up the hot tub is start with kindling and
paper (fire lighters (tablets) can be used). When the flame is getting bigger
you can add bigger pieces of wood. It is recommended to use dry wood. Fire
intensity can be adjusted with the lid located on the top of the heater which
regulates the air intake into the burning chamber.

IMPORTANT–do not load
more than 2 thirds of wood of the height of the heater.
IMPORTANT- if the hot tub is not filled up to the right level, you can’t light
the heater, because the emitted heat will damage the tub and the heater.
IMPORTANT–make sure you do not add too much wood, so the flames won’t go
through the lid.

IMPORTANT- water from
the hot tub can be drained only when the heater is completely cooled down.
Otherwise, the heat will damage the hot tub and the heater itself.

HOT TUB WITH EXTERNAL HEATER

External heater, as
well as an outdoor hot tub must be placed on a flat, firm ground. It is
important that the front of the heater is slightly below. Additional pump or filtration
system to assist with heater’s circulation are not allowed.

When the hot tub is
filled up with water (10cm from the top of the hot tub edge), you can fire up
the heater. The best way to fire up the hot tub is start with kindling and
paper (fire lighters (tablets) can be used). When the flame is getting bigger
you can add bigger pieces of wood. It is recommended to use dry wood. Fire
intensity can be adjusted with the air intake openings on the door.

IMPORTANT – keep in
mind until the hot tub has the appropriate amount of water, you can`t light the
heater, because the emitted heat will damage the tub.

IMPORTANT – water from
the hot tub can be drained only when the heater is completely cooled down.
Otherwise, the remaining heat will damage the hot tub and the heater itself.

HOT TUB WITH
INTEGRATED HEATER

When the hot tub is
filled up with water (10cm from the top of the hot tub edge), you can fire up
the heater. The best way to fire up the hot tub is start with kindling and
paper (fire lighters (tablets) can be used). When the flame is getting bigger
you can add bigger pieces of wood. It is recommended to use dry wood. Fire
intensity can be adjusted with the air intake openings on the door.

IMPORTANT – fill up
the  tup 10cm from the top before lighting the fire.

IMPORTANT – drained
the water when the heater is cooled down. Otherwise, the remaining heat will
damage the hot tub and the heater itself.

HOT TUB WITH ELECTRIC
HEATING

When the hot tub is
filled with the right amount of water (fill leaving 10cm space from the top of
the hot tub edge), you can turn on the electric heater. First, activate the
circulation pump with a buttons that is on the panel of the tub. Set your desired
temperature. The temperature is controlled by swirling dial (knob) located on
the heater. When the temperature reaches the target (the desired heat level)
electric heater shuts off automatically. When the water cools down, the heater
turns itself on automatically to heat the water up to your adjusted
temperature.

To completely turn off
the heater, turn the circulation pump off (circulation pump is
activated/deactivated with the same button on the panel of the tub).

IMPORTANT–when
draining the water out of the hot tub, the electric heater must be switched off
(including the circulating pump).

IMPORTANT –do not turn
on the heater if the water level hasn’t reached its recommended level. NOTE:
electric heater usage during sub-zero outdoor temperatures:

·   
–  The roller needs to be pointing on 0 C° before filling up with
water.

·   
–  Pour 20-30l of warm water in the hot tub, and turn on the
circulation pump. Check if the water circulates.

·   
–  Fill the hot tub with water to the recommended level.

·   
–  Once the hot tub is filled with the recommended amount of water,
set your desired temperature.These steps need to be made during the cold
season, when the outside temperature is below zero, so the circulation-pump
won`t freeze.

USER INSTRUCTIONS

BEFORE START IGNITION

Please check to make
sure that the gas type is in accordance with the one stipulated on the name
plate. Before igniting, open the cold water valve. Open the master gas switch
and check that there is no leakage.

START IGNITION, WATER
COMES OUT

Start ignition: Open
the cold water valve, (or start the pump) the burner starts to ignite with a
continuous “pa”sound,which stop after burning starts; hot water comes out
immediately. Note: When using this appliance for the first time, or after a
long period between uses, repeat ignition is needed to discharge any existing
air in the gas pipe. Use the knob “Gas”, “Water” and “Power” to adjust the
water temperature.

With “Gas” and “Power”
set to the Max position gives the maximum power. The knob “Water” adjust the
water flow so that the Max position gives greater water flow and thus lower temperature
out from the heater and vice versa.

For a temporary stop
during use, close the hot water valve or stop the pump. The burner will stop
burning automatically. Open the valve or start the pump for hot water again.

Note:Because the water
will get very hot during a temporary stop,wait for a few seconds before coming
into contact with the water

STOPPING THE HEATER
(WATER STOPS COMING OUT)

To stop the water
heater after use,close the hot water valve or stop the pump, the flame of the
burner will go out automatically, and the water heater stops working.

Close the cold water
valve or pump. Close the master gas valve.

PREVENT BURNS ON EYES

Upon ignition, never
look at the flame with eyes close to the inspection hole. Keep your eyes a
minimum of 300mm from the inspection hole.Wait 10
20seconds before
repeating ignition.

PREVENT THE HEATER
FROM FREEZING:

·   
In very cold areas (with temperatures below 0 ), please remove the draining
stopper after use to release access water. It’s also recommended to disconnect
the heater and move it to a storage place without risk for freezing.

·   
Some parts of the water heater may become loose due during transportation.
Incaseof damagestotheexternalhousingafteropeningthepackage,geta
repairmantocheckbefore use.REPLACE THE BATTERIES.

·   
Replace the batteries if you see the following situations upon ignition or
as the water comes out.

·   
Longer interval of sounds of “Pa,Pa” during ignition (approx. 2 sounds a
second)

·   
The flame goes out shortly after ignition.ABNORMAL HANDLEIn case of
abnormal burning (flame
retrace separated flame, yellow flame or
dark smoke etc.) unexpected smell, noise or emergency (earthquake or
fire),remain calm to close the water heater to stop burning, close the gas
valve afterwards and contact the service department or the gas
supplier.MAINTENANCE &SERVICES

·   
The water heater needs cleaning periodically (generally once every half
year) to ensure its normal performance. Check the flame frequently, in case of
a yellow flame with dark smoke, informs the service department for cleaning. To
clean the external housing, please gently mop it with a wet cloth followed with
a dry cloth. If the water heater remains unused for a long time, cover the top
to prevent dust. Never use chemical detergents for cleaning; otherwise, the
external housing would become faded and lose its gloss. All abnormalities must
only be handled by qualified personnel.

·   
Note: The room installed with the water heater must have a fixed open airinduction opening. Closed windows are ineffective.

IN CASE OF GAS
LEAKAGE, NEVER MAKE A FIRE OR TOUCH ANY ELECTRIC SWITCHES,

Regularly check the
pipe to make sure of good air tightness. If cracked, replace the pipe at once.
Under normal conditions, the gas pipe needs to be checked once a year.

·   
If the gas pipe is cracked, stop using it and replace it. For users of
Propane: if the flame of the water heater is inconsistent, it may be due to a
malfunction of the gas pressure reducer, Stop using the pressure reducer and
replace it, or get it repaired and installed by a professional technician.

·   
For users of piped gas or natural gas: if the flame is abnormal, it is due
to an unstable gas pressure. Stop using the water heater temporarily.

·   
 Continued use will damage the water heater and possibly cause an
accident.

COMBINED SPA SYSTEM

Water massage system
structure: air compressor 700W power and water compressor (900- 1100W), 6 pcs.
combined water / air jets – installed in the tub wall, additional 4 units of
air jets.

Combined massage
system has 2 switches in the tub panel. One of them turns on / off the air
compressor, the other switches on / off water compressor. You can enable or air
massage or water massage, or both devices together. After releasing the water
from the hot tub, keep the air massage active for 30 seconds to remove water
from the system.

IMPORTANT–in the cold
season, you can turn on the air system only when the water temperature is above
30C°.

WATER FILTERS

CARTRIDGE FILTER

Cartridge filter is
being built next to the tub and connected by two hose through which filter
water in the tub.

IMPORTANT–in the cold
season, when the air temperature is below 0 degrees, it is necessary to close
the filter openings inside the tub, so the water can`t reach and freeze the
filter connection hoses.

When heated tub warms
up to +30 degrees, open the filter openings. If the tub is kept at a constant
temperature, the filter can be used in sub-zero temperature.

SANDFILTER

Sand water filter is
being built next to the tub and connected by two hose through which filter
water in the tub.

IMPORTANT–in the cold
season, when the air temperature is below 0 degrees, it is necessary to close
the filter openings inside the tub, so the water can`t reach and freeze the
filter connection hoses.

When heated tub warms
up to +30 degrees, open the filter openings. If the tub is kept at a constant
temperature, the filter can be used in sub-zero temperature.

SKIMMER

Skimmer – immersed in
water filter. In order to filter the water in the hot tub into the, the skimmer
is immersed filter which is connected to a power.

The skimmer can be turned
on during bathing in the hot tub because it brings 12V electric current.
