OVER HEATING WHEN BURNING SOLID FUEL AS
YOUR PRIMARY SOURCE OF HEAT
If your home is overheating, your furnace is providing heat when the thermostat is satisfied. One of these ideas will help with overheating.
1.The best answer is to use fewer logs at each filling. This provides the maximum amount of heat while conserving wood.
2.There are 3 pegs in the fan and limit control. One peg is set at 250º F. Never change this setting. The middle peg is set at 150º F. This is the temperature setting that the air circulating fan starts. You may want to set this setting at 160º F or higher. The bottom peg is set at 120º F. Reset this peg to 130º F or higher. These new settings will not allow the fan to run as much. This reduces the amount of air provided to the rooms.
NOTE: You will not have continuity of operation if you make adjustments to fan and limit control. This means that your air circulation blower may not operate continually when burning oil or gas.
3.You may feel that the furnace is oversized for your requirements. If this is the case cover part of the grate with a piece of heavy metal. This will retard the fire. This will cause some creosote buildup in firebox and chimney because it will not burn as clean.
GAS OR OIL PART OF FURNACE TOO LARGE FOR
THE HOME
You or your furnace service provider may feel the furnace BTU input is too large or too high. This will cause the gas or oil blower to not operate continually when burning oil or gas. BTU input can be reduced to as little as 75,000 BTU input. Choosing this option will require adjusting the air circulation blower to a lower speed. This assures continuity of operation. Slowing the blower down will allow the blower to run continually. This occurs when the thermostat is calling for heat from the gas or oil burner.
IMPORTANT: During normal operation, firing door and ash drawer must be kept tightly closed. Air leakage will cause loss
of efficiency resulting in higher heating costs. If door gaskets become worn, replace with 1/2" fiberglass rope available from local sources.
NOTE: The damper will automatically close if there is an electric power failure. This can occur from high limit
This will prevent heat exchanger damage.
