2. Operation manual
2.1 Important safety instructions
In case of conditions leading to danger of temporarily present flammable gases or when there is a danger of fire or explosion
present at some kind of work (e.g. bonding of floor coverings), the fireplace must be shut off before the danger arises.
The fireplace must be operated according to this manual. It can be only operated by adult persons; it is unacceptable to leave
children close to the fireplace in operation.
No flammable liquids can be used to heat up.
IT IS FORBIDDEN TO INCREASE THE NOMINAL THERMAL POWER OF THE FIREPLACE USING FLAMMABLE LIQUIDS.
The fireplace must not be operated with stoker door open.
Ash has to be disposed of carefully, and placed in nonflammable containers with cover; hot ash cannot be placed in ash bins or
kept it open air.
Damaged or nonoperational fireplace must not be used. The user must provide its professional repair before using it again.
Ash accumulation in smoke tubes and bends must be checked at least once a month and cleaning provided when required.
During operation, all air supplies to fireplace must not be closed.
During operation, it is necessary to monitor the functions of the fireplace and the fire safety. You must check the amount of fuel in
the hearth, sooting of the grate, conditions of control mechanisms of combustion air, if the door is closed and if the surrounding is
clean.
Broken fire brick in hearth is no obstacle to further use of fireplace. This does not apply to ceiling vermiculite.
When used simultaneously with other heating device, proper area venting must be provided (see part 1.4).
2.2 Fuel
This fireplace is intended for use of: wood, brown-coal brique
ttes 7”, 6” long.
Emission standard dictates that only naturally dried wood (humidity content max. 20%) can be used. Wet wood causes strong tar
condensation. The most suitable are wooden logs with diameter of 30 cm and 30 cm long, stored in dry place for at least 2 years.
Most suitable are: beech, oak, hornbeam, birch and fruit trees wood.
Unsuitable or unacceptable fuel:
Only fuel mentioned above can be used.
Unacceptable for use is also: carbon grit, finely chopped chips, bark and chipboard waste, wet wood and wood treated by a
prophylactic, paper and pasteboard (except heating up).
Waste combustion is forbidden by Law of protection against emissions.
Combustion gases produced by waste combustion can threaten your health and cause damage to fire bricks and metal parts of
your fireplace and to your chimney.
2.3 Fireplace setting
The fireplace has control sliders for supply and control of combustion air flow:
-
Primary air: one control slider on stoker door at the bottom.
-
Secondary air: one control slider on stoker door at the upper side.
Control sliders
are marked with signs: “0” – closed, “I” – open.
NOTE: the control mechanisms can be very hot! Use the glove supplied as an accessory for manipulation of hot objects.
2.4 Heating up
Before heating up you must
open all air suppliers (control valves to “I”). At the same time, ensure air supply to the room (see part
1.4). Recommended fuel should be supplied at the nominal thermal power in intervals of one hour.
Fire is set up using paper and thin wooden chips. Never use petrol, alcohol, kerosene, etc. Place a layer of wooden logs and
briquettes on the fire.
Never use more than three wooden logs as fuel load.
When using the fireplace for the first time, heat it up with a small fire. First, wait until the fire becomes bigger so that the fireplace
could slowly and evenly extend and the fireplace body will not suffer any damage due to temperature tension.
To achieve this, you have to set the control valves for both primary and secondary air immediately (once the fire is burning well) to
medium setting.
In case of difficulties with heating up (weather changes, cold chimney, etc.), local fire is set up in the fireplace using paper to heat it
up better. During heating up it is necessary to check on the combustion and constantly monitor the fireplace.
The fireplace is covered with heatproof paint that hardens at higher temperatures. Therefore smell is produced during the first
phase of heating up. For this reason, especially at the first use, sufficient venting must be provided.
We do not recommend touching the external paint of the fireplace when using for the first time, because it is not yet hardened and
it could be damaged.
