OPERATING YOUR WOODCHUCK
FURNACE
STARTUP
Never leave ash pan in unit. Use only when cleaning
out ashes.
First thing is to check that your main blower and draft
blower are in proper working order before lighting a fire.
To check main blower, push button on fan/limit control
for manual override testing. When finished, reset to au
-
tomatic position, figure 5. Next, turn thermostat upstairs
to high temperature so draft blower turns on.
NOTE: All models are equipped with a “low limit” which
will not allow the auto draft to operate when the unit is
not warm. To start auto draft, turn Lo-Limit toggle switch
on comfort control center to “On”, figure 6.
Now you are ready to light a fire.

paper in the center of your Woodchuck. Criss-cross a
couple of handfuls of dry kindling wood 3/4" thickness,
then several small dry pieces of firewood. Ignite the pa

per and close the door. Do not attempt to open the door
immediately after igniting the fire. There could be a
flame flash out.
2. It will take 5-10 minutes for the fire to establish itself.
Once you have some good red hot burning embers,
add larger pieces of wood. All chimneys and hookups
are different. After 3-4 fires, you’ll find out how your unit
works for the best starting.
3. After about 30-40 minutes you can adjust the draft
according to your needs. Adjust smoke pipe damper ac
-
cording to your needs also.
