Yukon SUPER JACK SJ125, Owner'S Manual, Page: 34 / 52

STARTING A WOOD FIRE
1. Place several pieces of crumpled paper in the center of
your firebox. In a criss-cross pattern, place a couple hand-
fuls of dry kindling wood 3/4” thickness, then several small
dry pieces of firewood.
NEVER USE CHEMICALS OR FLUIDS SUCH AS
GASOLINE, CHARCOAL LIGHTER FLUID, DRAIN OIL OR
KEROSENE TO LIGHT A FIRE IN YOUR JACK FURNACE.
2. Ignite the paper and kindling with a match. Close the
door. Do not attempt to open door immediately after igniting
the fire. There could be a flame flash out.
Super Jack models only : Pull out pull handle before light-
ing fire. This opens the secondary heat exchanger damper.
3. Turn thermostat above room temperature. Draft blower
will start. Make sure the Air Inlet disc on draft blower is
open. Adjustment can be made after fire is established.
4. It will take a few minutes for the fire to establish itself.
Once you have some burning embers, add larger pieces of
wood.
DO NOT ALLOW BURNING EMBERS ABOVE
THE TOP OF FIREBRICK.
5. Open manual draft spinner (on fire door) 3 - 4 turns. This
manual draft spinner controls the amount of secondary air
allowed into the firing chamber. Shutting it off tight will
make for a slower burn but will allow creosote to build up in
furnace, smoke pipe and chimney. Leaving it open will in-
crease the efficiency of the burning wood by up to 40% and
reduce creosote buildup. The wood fire will not last as long
as secondary air, while burning the unburned gases at the
top of the flame, tends to burn the wood a little faster.
6. After substantial fire has been established for at least 30
minutes, set Barometric Draft control to .-03 using a
Manometer.
7. When desired room temperature is reached, set thermo-
stat accordingly.
NOTE:
All chimneys act differently depending on chimney size,
chimney draft and the moisture content of the wood. You
may have to experiment with different levels of wood logs
until you are satisfied with the heat output.
USE CAUTION WHEN OPENING LOADING DOOR.
AVOID OPENING LOADING DOOR RAPIDLY. THIS COULD
CAUSE FLAME TO FLASH OUT DOOR. THIS OCCURS WHEN
THERE IS UNBURNED FUEL AND A LARGE AMOUNT OF
GASES ON TOP OF THE FIRE BOX. WHEN THE DOOR IS
OPENED, OXYGEN IS COMBINED WITH THE GASES AND
IGNITES.

NOTE: When your furnace is new, there may be a
small amount of oil on the metal - you may smell an
odor until the oil evaporates, which is usually a
minutes. After the first few firings, the odor disappears.
