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 cut-off or electrical power outage.
This will prevent heat exchanger damage
