Maintenance - Jydepejsen Sigma Mode D'emploi

Start-up stage
1. Place the air wheel in position 4.
2. Place firelighters and kindling on the bottom of the fire chamber.
3. Place approx. 1.2kg kindling in the shape of a matchstick house.
4. Light the fire.
5. Once the wood has caught fire, move the handle to position 3
or less (to the left.) Close the door.
6. Just how much closure is required depends of the up-draft in the chimney
and the heat requirement.
Stoking
This wood-burning stove is intermittent, meaning that fresh wood is required for stoking once an adequate layer of embers
has been achieved on the fire chamber floor. The heat requirement determines the amount of stoking, and the level of
stoking depends of the season. In order to ensure optional combustion, use 3 0,7 kg. logs, approx. 30 cm in length which
are placed side by side on top of the embers from the kindling process. This will give you a combustion time of approx. 45
minutes.
It is important to keep the door closed when flames are visible in the fire chamber to avoid smoke nuisances in the
room.
1. Move the air wheel handle to position 4 (maximum air supply.)
2. To minimize the negative pressure, the door to the fire chamber should be ajar for about 1 minute before it is fully
opened.
3. Open the door slowly.
4. Place 3 x 0,7 kg. logs (30 cm in length) next to each other on top of the embers.
5. Close the door again.
6. Once the wood has caught fire, the handle should be moved to position 3 or lower. You have achieved healthy
combustion when the flame is steady and almost transparent.

8. Maintenance

Sealing bands and vermiculite plates are wearing parts and should be replaced as needed. How often depends of the use
of the stove - some stove owners have to change the parts every year whereas others replace them every two or three
years. Sealing bands should be replaced when flat and the front door is no longer tight. New sealing bands with glue may
be ordered from your wood-burning stove dealer.
The vermiculite plates should be replaced when they appear worn or have deep scratches revealing the fire chamber steel.
Worn vermiculite plates should be replaced in time as they will otherwise loose their heat reflection and insulation
properties. Movable and mechanical parts should be greased with a heat-resistant lubricant at least every year (locking
mechanism, hinges, etc.)
The stove and the chimney should be checked regularly by a qualified professional to ensure the optimal function of the
stove. It is illegal to make unauthorized changes to wood-burning stoves and doing so will void the warranty and the test
results.
Replacement of door sealing band
1. Remove the sealing band from the inner frame of the door and clean the band groove. (Do not dismount the door.)
2. Apply fireproof glue to the groove where the old sealing band was seated.
3. Press the new sealing band into the groove.
4. Close the door and let the glue harden for 24 hours before opening the door again. Insufficiently hardened glue
could result in the sealing band falling out.
