Bringing Into Service Condition And Burn-In; Side Water Tank Wtr And Wtl; Heater Stones, Placing The Stones - KASTOR Karhu-22 Installation And User Manual

•
Sea water, rainwater or water containing chlorine must not be thrown onto the stones, use clean water only.
•
In the proximity of sea water, there is also the risk of corrosion for the heater; operating life may be shorter.
•
Decorative or other items must not be placed on the heater. The heater must not be covered when it is heated, or
when it is hot. E.g. drying clothes or other flammable material on the heater is forbidden due to fire risk.
•
In order to guarantee full output and safety, the fire door must always be kept shut when heating. The fire door can be
open during heating only when adding more firewood, and the heater must be continuously observed. Monitor sauna
temperature so that the heater will not overheat. If the heater becomes overheated, open the sauna door and allow
ventilation.
•
Fire doors and glass surfaces must be handled carefully.
•
The fire door handle may be hot; use a tool, e.g. a glove, when opening.
•
If the heater has not been used for a long time and is located in a damp space (e.g. an unheated holiday house), it must
be carefully checked before use for corrosion damage and to make sure the chimney is not blocked, for example by a
bird's nest.
•
If a chimney fire occurs, or if there is a risk of one, close the fire doors but leave the damper on the flue open.
•
Call the fire brigade if you need help with putting the fire out. After a chimney fire, a local chimney sweep must always
check the condition of the flue.
•
A chimney fire, even one that was put out, must always be reported to the fire authorities.
•
Be careful! Handles, fire door glass and the surface of the heater, as well as recirculated air may be hot!
•
Do not let children light fires or stay near a burning fire unless supervised by adults.
•
Follow the instructions when heating and installing the heater.
•
The heater can only be heated using unprocessed firewood.
•
Structural changes must not be made to the heater.
•
Only use original equipment and parts approved by the manufacturer.
2. Installation and preparations for use

2.1. Bringing into service condition and burn-in

•
Install the handle to the door.
•
Place the heater on a non-flammable surface outdoors, without stones.
•
Models with a water tank: attach the tap and the cap, fill the tank with water.
•
Remove all extra stickers and protective plastic (excluding type/CE mark stickers).
•
Make sure that the grate is in place.
•
Install the included connecting pipe to the flue opening above the heater, the shorter section into the heater.
•
Check that the caps for the soot hatches and the flue opening are secured.
•
BURN-IN: The purpose of burn-in is to burn the protective agents off the stove outdoors, and cure the heater finish. Burn
a furnace-full of small chopped wood. Continue burning the heater outdoors until the heater emits no odour.
•
Let the heater cool down and move it indoors to the sauna.
•
Make sure there's ample ventilation during the first heatings.

2.2. SIDE WATER TANK WTR AND WTL

Empty the water tank before outside temperatures drop below zero; the tank will be damaged if water freezes in it.
Do not heat the heater while the water tank is empty
Remove any plastic film from the tank cover
Installing the water tank tap. Figure 1.
A tap, two seals and a nut are included. The tank is attached as follows:
•
Lift the water tank off.
•
Place the first seal on the threaded part of the tap.
•
Push the tap into the hole on the heater cover.
•
Place the second seal on the threaded part of the tap inside the cover.
•
Lift the water tank back into position and place the tank hole onto the threaded part of the tap.
•
Place the edge of the water tank on the side bracket.
•
Place the nut into the threaded part of the tap and tighten with a wrench from inside of the water tank. Do not tighten too
much to avoid damaging the gaskets.

2.3. Heater stones, placing the stones

Use peridodite or dunite stones over 10 cm in diameter. Wash the stones before placing them into the stone compartment.
Do not place the stones too tightly or pile them too high. Leave enough space between the stones. Place the stones
vertically instead of horizontally to allow hot air flow from underneath all the way to the top stones. Fill the entire stone
compartment, place flat stones vertically, pay attention to the maximum amount of stones. Table 1
More balanced heat properties can be reached by using a mix of differently sized and different types of stones and
adjusting the amount of stones. As stones and layouts are unique, there are no generally applicable rules. Try placing the
stones in different ways to find the ideal layout for your needs.
In order to operate properly, it is vital that hot air can flow freely in between the stones and heat them up quickly. If the
stones are too small or incorrectly laid, the air in the sauna space will heat up, but the stones won't.
Clean the stone compartment and check the condition of the stones approximately once every six months.
