2.4 CONNECTING THE OUTDOOR COMBUSTION AIR FEED PIPE
The fireplace may also take in its combustion air from outdoors. For this, there is a air intake pipe connection part (diameter 63.5 mm) beneath the
fireplace's bottom. The fireplace's bottom and rear wall have removable knockouts, through which the air intake pipe can be fed into the fireplace
and attached to the furnace. (Picture 22)
2.5 FOUNDATION
Make sure that the supporting floor can carry the weight of the fireplace. The floor must also be smooth and horizontal.

If the fireplace is not attached from the back wall to a masonry flue, but from the top, the weight of the chimney must be accounted for as well.
Further information and guidance about the installation can be requested from the local fire department.
2.6 SAFETY DISTANCES
The given safety distances must be adhered to under all circumstances to prevent fire hazards!
If the fireplace is installed on a floor that consists of flammable material, a protective plate made of metal or equivalent fireproof material must be
placed in front of it. The plate must extend 400 mm in front and at least 100 mm to each side of the feed door.

If the fireplace is connected to a masonry flue that is wider than the fireplace, a 50 mm aperture must be left in the rear.
3. USAGE
3.1 GENERAL INSTRUCTIONS
Although the fireplace has been heat treated, a slight amount of paint odour may emerge during the first heating.
During the first heatings, the environment should be aired.
Do not burn overly large loads. The heat output rises excessively and may damage the fireplace .
The instructions apply to leafwood. Burning the same amount of coniferous wood causes higher temperatures in the furnace.
If the surface of the cladding changes or the colour comes off, the fireplace has been heated too much. If, in addition to this, the steel parts start
bending, the heat output exceeds permitted levels by far. Kastor does not cover damages of this kind.
Always remember the safety instructions listed under “Important Instructions”.

3.2 FUEL
The fireplace is heated only with untreated firewood.
The wood should have a humidity of 15–20 % for optimal burning. Excessively moist wood will blacken the glass door and the chimney with soot.
Soot accumulation in the chimney also increases the possibility of chimney fires. Burning moist wood causes more smoke and pollution, since the
burning can't advance cleanly. It also does not give off optimal heat, since part of the energy is used in turning the moisture into steam. Firewood
that is stored outdoors should be taken inside for a few days to allow the surface moisture to evaporate.
Warning:
Do not use impregnated wood, chipboard, laminates, liquid fuels or anything similar even for starting the fire. They may contain substances that will
damage the fireplace and the chimney.
Wood chips or very small pieces of wood should not be used during the proper heating phase, since they produce very high temperatures that may
damage the fireplace. (Building material often contains hazardous substances.) Only store as much wood close to the fireplace as you burn during
a single session. A small amount of wood can be stored in the container beneath the fireplace, but it must not be filled right up to the brim.
When wood is stored close to the fireplace, the safety distances mentioned in 2.6 must be kept.
3.2.1 IGNITION (Picture 23)
The furnace should have a sufficiently large load of wood to ensure that a high enough temperature is reached quickly. At low temperatures the
burning process does not work correctly and the fireplace and chimney are stained with soot. The fire may also go out, if the chimney does not build
up enough draught. Devices causing low pressure must be shut off or the window opened during the ignition phase until the chimney develops
enough draught to counter the low pressure. During the ignition phase, about 5 min., the air regulators can be kept open or the feed door ajar. Once
the fire is going, you use the air regulators to adjust the burning to the level you want. During the ignition phase, you use smaller firewood with a
