IMPORTANT: Electrical work must be performed by an authorized technician.
WARNING: This section is only for qualified technicians.
SETTING THE CIRCUIT BOARD (fuel stirrer option is not used on the 6500 furnace)
If the low fire heat setting is too low for the fuel that
you are burning and the fire goes out, the number 1 or
2 heat setting can be adjusted through the access hole
located next to the system indicator light. (2)
If the draft setting is too low on the number 1 or 2-heat
setting, it can be adjusted through the access hole
located next to the fuel stirrer knob. (1)
To adjust the settings, place a small screwdriver
through the hole to the adjustment screws. Turning the
screw clockwise increases the draft and
counterclockwise decreases the draft. (1) Turning the
screw clockwise increases the fuel feed rate and
counterclockwise decreases the fuel feed rate. (2)
The systems indicator light will blink showing the
number that you are on. There are 10 settings that are
available with 1 blink being the lowest and 10 blinks
being the highest. When you turn the adjustment
screw to the next setting the light will blink the number
that you are on and then the light will stay on.
(Example: If the setting is turned to # 9 the light will
blink 9 times and then stay on).
Draft Adjustment
Note: Number 1 on the draft adjustment setting is the
lowest setting and on the Fuel Feed rate adjustment
setting it is the lowest feed rate. As you turn the
adjustment screw clockwise 1 – 2 – 3, etc the draft (1)
will increase and the fuel feed rate (2) will increase.
The normal settings on both should be 1 blink
