Smoke and Soot Odor:
Troubleshooting:
• Is there downdraft in the chimney? This can occur in certain wind directions.
• The chimney might be too short in relation to the roof ridge and/or surrounding trees/buildings, not providing sufficient draft.
• Ensure there are no open windows where smoke can enter.
• Keep the door closed while there are flames in the stove. (If the door is opened while flames are present, smoke can escape
into the room.)
• Is the firewood dry (maximum 20% moisture content)?
• Is the air control handle closed too far?
• Is there a sufficient bed of embers to ignite the new wood you're placing on?
Glass Soots Up When Using the Stove:
Troubleshooting:
• Is the firewood too moist (maximum 20% moisture content)?
• Is the temperature in the combustion chamber too low? Open the air control handle further.
• Insufficient draft in the chimney.
• The air control handle is closed too much.
• The door is closed too early during lighting.
• The firewood is placed too close to the glass.
• There is insufficient airflow into the room.
Smoke comes out when the door is opened or slightly ajar:
Troubleshooting:
• When you open the door, the negative pressure in the stove disappears, making it easier for smoke gases to escape into the
room rather than passing through the smoke baffle plates. Therefore, never open the door while there are flames. If there are
flames, there are smoke gases!
• Some types of wood can release smoke gases even if there are no flames, especially if there hasn't been enough air or a bed
of embers during combustion. The logs may continue to release smoke for a while after the fire has gone out – wait before
opening the door.
• There is insufficient draft in the chimney.
• Turn off the kitchen hood extractor fan, even if it's active in another room. If turning off the extractor fan is not possible,
ensure that the stove gets fresh air from outside (consider opening a window).
White Glass (if the glass appears slightly cloudy and white):
Troubleshooting:
• The glass has become too hot because the startup air intake was not closed in time. The glass has suffered alkali degradation
due to the high heat and should be replaced.
• Incorrect fuel (burning waste wood, painted wood, treated wood, plastic laminate, plywood, etc.) These issue are caused by
improper operation and falls outside of warranty coverage.
5 Maintenance and Cleaning
Cleaning and Inspection
Daily maintenance is kept to a minimum, but the stove should be thoroughly inspected and maintained once a year. The chimney
and stovepipe should also be cleaned by a chimney sweep, who will determine the necessary cleaning/sweeping intervals. Cleaning
the stove should only be done when the stove is cool.
Firebox
Should be cleaned of ashes and soot. It may be necessary to remove the insulation plates/vermiculite for cleaning, but be cautious
as they are very porous and can break during removal/reinstallation. Refer to section 8.1.
Insulation Plates
Insulation plates in the firebox that are cracked or worn can be easily replaced as they are loosely mounted. The material used is
called vermiculite, which is a porous but highly suitable insulation material. The stove's efficiency is not affected if the insulation
cracks. However, they should be replaced when wear exceeds half of the original thickness, if the plates are falling apart, or at the
chimney sweep's recommendation. For replacement instructions, refer to section 8.1.
Door Hinges and Moving Closure Mechanisms
The door hinges should be lubricated with copper grease or another heat-resistant lubricant. This also applies to the moving parts
of the closure mechanism on models equipped with it.
