Safety Notes
1. The stove is HOT during operations; even more so is the flue; as such WHEN THE
STOVE IS ON, DO NOT EVER TOUCH IT.
2. 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 temperature) and ruin future enjoyment of the wooden hot tub.
3. Due to increased heat present in a hot tub, you SHOULD NOT use the hot tub, if
you are under the influence of Alcohol or any Psychotropic substances. This
also applies to any other conditions wherein bathing would be an issue, if you’re
unsure you should speak with your doctor about this.
4. 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.
5. The water level in the tub must be always above the HOT water outlet while the
stove is in use.
6. During powerful windstorms 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.
7. 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.
8. Children should never be left in control of the stove while in use and should also
NEVER be left unattended either while bathing.
9. For your own safety you shouldn’t bath alone!
10.You can always add cold water to the hot tub, if you find the temperature is too hot
for you.

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

Never leave home, while fire is active inside the stove (for example: go shopping while
the hot tub is heating up).
If the hot tub was in use before the bedtime, make sure fire has stopped inside the
stove before going to sleep!

Where to place your Hot Tub
NEVER PLACE YOUR WOOD BURNING HOT TUB NEAR FLAMMABLE
OBJECTS (for example: house, wooden shed, garage and ect.)

A hot tub is usually around 200-270kgs, 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
Most 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.

The tub could be lifted by a group of four to five people and carried into position,
otherwise a crane or telehandler service may be more applicable depending on your
land and where you want to put it.
If the hot tub is with the external log burner then 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 (most of time we send slightly longer heating
pipes, which means they need cutting (making shorter). All depends on your set up. The
main rule that top heating hose is going upwards from the stove to the hot tub.

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.

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 around 800 -1500 litres of water (depends of the model).
Once you’ve filled the tub, and ONLY after filled you can 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 ensure a strong fire.
Occasionally you MUST to stir/mix 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. Also
regular mixing of water prevents the hot tub from overheating as hot water stays on
the top.
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 2-3 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.
STIR/MIX water regularly to prevent the hot tub from overheating.
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.
IF YOU STOP using hot tub, try to “kill/reduce” the fire inside the stove. You should
never leave big fire in the stove unattended, which could cause overheating of the hot
tub, fire escape from the log burner, and ect.

Maintenance
Wood fired Hot Tubs don’t require as much maintenance as a modern whirlpool one.
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. 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.

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.
COMPOSITE CLADDING – the cladding will discolour due the sun. Steps needs moving
away from the hot tub, while the hot tub is not in use, so there is no shadow. Otherwise
colour of cladding will be different in the area where steps were.

GENERAL INFORMATION ON HOW TO USE THE HOT TUB
BASE & THE HOT TUB PREPARATION
The hot tub needs to be placed on a flat, levelled 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 (tap 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) it requires to connect the hot tub to the outdoor power socket connected directly
from your fuse box. Also RCD (residual current device) protection is required. The
outdoor socket must be minimum IP66 Rated. NEVER USE THE EXTENSION LEADS
to power the hot tub up.
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 heater wiring needs to be done by
approved electrician. All power supply must be connected to the fuse box directly,
also RCD (residual current device) protection is required.

THE HOT TUB HEATING
IMPORTANT - The fiberglass/acrylic hot tub temperature can’t go higher than +50C°
as higher temperatures can damage the fiberglass gel coating or the liner itself (will
start blistering or the shell deform). Once the hot tub is fired up, you need to make sure
stirring of the water with the paddle done by the person regularly, so the hot water
doesn’t concentrate around the heater’s outlet. If bubble systems installed, then mix
water by turning the bubble system time to time.

THE HOT TUB WITH INTEGRATED LOG BURNER
When the hot tub is filled up with water (10-15cm from the top of the hot tub edge), then
you can fire up the log burner. The best way to fire up the hot tub is start with kindling and
paper (fire lighters 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 tub 10-15cm 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.

THE HOT TUB WITH EXTERNAL LOG BURNER

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 is not allowed.

When the hot tub is filled up with water (10cm from the top of the hot tub edge), then you
can fire up the log burner. 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.

THE HOT TUB WITH ELECTRIC HEATER
When the hot tub is filled up with water (10-15cm from the top of the hot tub edge), then
you can turn the electric heater on. The temperature is adjustable, by turning the knob
clockwise (increase temperature) or anticlockwise (decrease temperature). Hot tub with
6kw heater is required 3 phase power supply. Less powerful heater is suitable with 1
phase power supply.
WATER, AIR OR COMBINATED MASSAGE SYSTEM
Combined massage system has 2 switches in the tub panel (Single systems have 1
switch). 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/hydro 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:
The Cartridge filter is being built next to the tub and connected by two hose through,
which filter water in the tub. Do not turn water filter on, while somebody is in the hot
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:
The Sand water filter is being built next to the tub and connected by two hose
through, which filter water in the tub. Do not turn water filter on, while somebody is
in the hot 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.
The skimmer can be turned on during bathing in the hot tub because it brings 12V electric
current.
PROHIBITED! Keep water in the tub, if the outside air temperature is below zero
temperature and the hot tub is not supported with fired wood heater or electric heater to
keep warm optimal water temperature.
