TROUBLESHOOTING

OVERFIRING DAMAGE

If the heater or chimney connector glows, you are overfir- ing. Other symptoms may include: Cracking, warping or burning out of components, gold door may turn color, stove glass may develop a haze, which will not come off with cleaning.

Overfiring of a stove is a condition where excessive tem- peratures are reached, beyond the design capabilities of the appliance. The damage that occurs from overfiring is not covered under the MANUFACTURER'S limited war- ranty.

The following are a few conditions that should be evalu- ated (and corrected, if necessary) if an overfiring condi- tion is suspected:

Overfiring Caused From Improper Installation - Ensure that all installation requirements have been met as out- lined in the installation manual. The chimney should be clean and in good repair. A draft test should be performed to determine if the draft requirements of the appliance are being met. A draft gauge should read between .05 and .07 inches water column (" W.C.). Excessive draft (above .07

"W.C.) will allow too much combustion air to be pulled in which results in hotter burns. Too little draft (below .05 " W.C.) will not allow enough combustion air delivery to maintain a fire (this may result in improper operation of appliance, i.e. wont maintain fire unless fuel door is left open. See below, Overfiring Caused From Improper Op- eration on this page.

Overfiring Caused From Improper Operation - Operate this appliance only as outlined in this manual. Never burn the appliance with the fuel door open or ajar. Do not oper- ate this stove with the primary air control in the "high" posi- tion (pushed in) for extended periods. This wastes fuel and can cause dangerous overfiring conditions. NEVER leave the stove unattended on high settings. Operation of the appliance with the Start-Up Air Control in the open (pulled out) position for extended periods can cause dangerous overfiring conditions.

Overfiring Caused from Improper Maintenance - Strictly adhere to all maintenance requirements at fre- quent intervals as prescribed in this manual including cleaning of flue and stove. Should the fuel door or glass gaskets become worn or damaged, they should be re- placed.

Overfiring Caused From Improper Fuel - This appliance is approved for use with natural dry well seasoned wood only (ask your authorized dealer what are approved fuels for your area). Do not burn garbage, particleboard scraps, or pressed logs using bonding agents because they can produce conditions that will deteriorate metal. Do not over- load or use kindling wood or mill ends as primary fuel as this may cause overfiring.
