Tar is a major cause of chimney fires - if you experience
problems with tar build up consult a chimney sweep before
continued use of your appliance.
Ideal working temperature range is 130°C and 240°C
(270°F–465°F).Failingtoclosedowntheprimaryair
control once the appliance has heated up to this range
may cause the appliance to over-fire and to exceed the
ideal temperature range. Over-firing can cause permanent
damage to the appliance and invalidates your warranty.

18. TROUBLESHOOTING TIPS
18.1 Stove glass blackening:
This has four possible causes:
1. Incorrect use of airwash–See Sections 1, 4 and 5 for the
correct use of the air controls.
2. Burning unseasoned wood–See Section 3 to identify
when wood is ready for burning.
3. Stove operated at too low a temperature - good working
temperatureis300-500°F(120–250°C).Astovepipe
thermometercanidentifythisproblem(Stovaxpartno
3046)
•Burnwiththeairwashcontrolfullyopenfor
approximately 20 minutes to cure this
The problem may be caused by damping your appliance
down overnight.
4. Problems with the flue–inparticularinsufficientairpull.
If the flue is not working efficiently the glass can blacken.
A flue which has too much downdraft may be too short or
needs lining or has too many bends. This can also cause
blackening of your stove glass. Contact the installer or a flue
specialist for advice.
18.2 Riddling mechanism jamming:
This occurs when fine ash builds up under the riddling bars
preventing movement. To prevent this:
•Followaregularcleaningroutinefortheinsideofyour
appliance
•Liftouttheriddlingmechanismandremoveallash
•Replaceriddlingmechanismwhencleaningiscomplete
18.3 Glass cracking:
Do not over tighten the screws on the glass clips when
replacing the glass as this causes stress and the intense
temperature changes can cause the glass to crack. For
replacement glass contact your local Stovax dealer.
