Yeoman YM-W9122FL Troubleshooting, Seasonal Use, Operating Instructions, Stove Glass Blackening

OPERATING INSTRUCTIONS

Damp / Rainy days – These sometimes result in problems when lighting and maintaining the fire, due to the lower flue temperatures and smaller difference between indoor and outdoor temperatures reducing the flue draught. Also, rain water running down the inside of the chimney reduces the flue temperatures. To help with this problem care must be taken to use good quality kindling wood, when starting the fire, and running the stove at a higher heat setting than normal for a period after start-up to fully heat the chimney. It could be possible to fit a rain cowl to the chimney to reduce this problem. Your appliance installer should advise you on possible solutions.

If the Yeoman stove emits smoke into the room continuously close the air controls and allow the stove to go out, and ventilate the room to clear the fumes.

Do not re-light the appliance until the cause of the problem is identified and rectified.

9. Troubleshooting

STOVE GLASS BLACKENING:

This occurs as a result of four possible causes:

1.Incorrect use of airwash – See the detailed operating instructions which show the correct use of the combustion air controls.

2.Burning unseasoned wood – See page 7 (section 9.1) for more information on how to identify when your wood is ready for burning. Properly seasoned logs will have been kept for a minimum of a year but are best burnt at 2 years.

3.The stove being burned at too low a temperature - A good working temperature is 300-500° F (120 – 250° C). A stove pipe thermometer will help identify this problem. (Part no 3046). Burning your wood stove with the airwash control fully open for a period of around 20 minutes ought to cure this. This might be caused by damping your stove down overnight.

4.Problems with your flue – in particular insufficient air pull. If your flue is not doing its job efficiently this can cause blackening of the glass. A flue which is too short, experiences a downdraft, needs lining or has too many bends can promote blackening. If you suspect your flue may be contributing to the blackening of your stove glass you should contact the installer or a flue specialist.

Heavy tar deposits should be removed using Glass Cleaner (Part. 4103 See section 2 page 8).

STOVE GLASS CRACKING:

Please ensure when replacing the glass in your stove that you do not over tighten the screws on the glass clips as this will cause stress in the glass and with the intense heating and cooling of burning your stove it may well cause the glass to crack.

STOVE IS PRODUCING TAR:

You can recognise this from the following traits:

Very strong pungent smell shortly after the stove is lit and as the stove heats up, glass blackening and, possibly, can be seen as a thick, brown and sticky material oozing from your stove pipe joints.

This is caused by burning damp wood and burning your stove at too low a temperature. To resolve this only use well seasoned wood and ensure your stove is operating in the ideal temperature range. Tar is a major cause of chimney fires - if you experience problems with tar build up, please consult a chimney sweep before continued use of your stove.

Ideal working temperature range is 130°C is 130°C and 240°C (270°F – 465°F). If you fail to close down your primary air control once the stove has heated up to this range you may cause your stove to overfire and the temperature to exceed the ideal range. Overfiring can cause permanent damage to your stove and will invalidate your warranty.

10.SEASONAL USE

10.1If the stove is not going to be used during the warmer periods of the year it is recommended to clean and service the stove, see Maintenance and Servicing section (page 9).

10.2The air controls should be set in the 50% open position to keep the appliance ventilated, and stop the build-up of any moisture inside.

10.3Before re-lighting the stove remove the baffles, clear any debris that may have accumulated, and check the flue is clear of any blockages.
