USER INSTRUCTIONS

16.Troubleshooting tips

16.1Stove glass blackening

This has four possible causes:

1.Incorrect use of Airwash

See User Instructions, Sections 1, 4 and 5 for the correct use of the air controls.

2.Burning unseasoned wood

See User Instructions, Section 3 to identify when wood is ready for burning.

3.Stove operated at too low a temperature

A stove pipe thermometer can identify this problem (Stovax part no 3046). The ideal working temperature range is 130°C - 250°C (270°F - 480°F). Failing to close down the Primary Air Control once the appliance has heated up to this range may cause the appliance to exceed the ideal temperature range and to over-fire. Over-firing can cause permanent damage to the appliance and invalidates your warranty. Burn with the Airwash Control fully open for approximately 20 minutes to cure this.

The problem may be caused by damping down the appliance during periods of extended burning.

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, needs lining, or has too many bends. This can also cause blackening of the stove glass. Contact the installer or a flue specialist for advice.

16.2Riddling Mechanism Jamming

This occurs when ash builds up under the riddling grate preventing movement. To rectify:

—Lift out the riddling mechanism (see Installation Instructions, Section 5) and remove all ash.

—Replace riddling mechanism when cleaning is complete.

—De-ash and clean the inside of the appliance regularly to avoid build up of ash and subsequent jamming of mechanism.

16.3Glass cracking

Do not over tighten the screws on the glass clips when replacing the glass. This causes stress and the intense temperature changes can cause the glass to crack. For replacement glass contact your local Yeoman retailer.

16.4Appliance is producing tar

This can be identified by:

—A very strong pungent smell shortly after the appliance is lit and heats up.

—Glass blackening.

—Thick, brown, sticky tar oozing from the pipe joints.

This is caused by burning damp wood and running the appliance at too low a temperature.

Use well seasoned wood and operate the appliance within the ideal temperature range.

Tar is a major cause of chimney fires. If the appliance experiences problems with tar build up consult a chimney sweep before continued use of the appliance.

16.5In the unlikely event of a problem that cannot be solved by these tips contact your installer or retailer for help.
