6 Troubleshooting
PROBLEM
REASON
SOLUTION
I. Poor control of fire in
the furnace.
1. Excessive quantity of combustion
air.
1. Reduce the quantity of
combustion air using the adjustment
lever in the fireplace insert.
2. Open chimney damper.
2. Close the chimney damper.
3. Excessive quantity of inserted
fuel.
3. Do not put more fuel and reduce
the quantity of combustion air, close
the chimney damper.
4. Worn gaskets.
4. Fit new gaskets.
5. Excessive negative pressure in
the chimney.
5. Install a cap type chimney
attachment and/or install a draught
moderator.
II. Fire cannot be lit up
in the furnace
1. Closed levers of combustion air
inlet.
1. Increase the quantity of
combustion air.
