Ignite the paper and close the door. Do not attempt to
open the door immediately after igniting the fire. There
could be a flame flash out.
It will take a few minutes for the fire to establish itself.
Once you have some good red hot burning coals, add
larger pieces of wood. All Chimneys and hookups act
differently. After a while, you will find out how your
unit works best for starting.
Push in bypass damper after fire has progressed.
Your furnace is capable of putting out many BTU's, so
don't fully load your furnace until you have become
familiar with the operation of the furnace. Keep in
mind, a full load will not always give you the best re-
sults for your needs. Note: With new steel, there is a
small amount of oil or dirt on the metal. You may smell
an odor. This is normal during the first operation. You
may want to assemble the furnace out of doors and
build a small fire in it to "burn off" this dirt and oil
before installing the unit.
When loading your furnace that has existing hot coals,
pull the bypass damper out and rake the red hot em-
bers over grate evenly. Put a few smaller pieces of
wood on the coals first, then load up to the middle of
the feed door.
Set rheostat setting for type and condition of coal or
wood. Hard coal and wood requires more forced air
than soft, so experiment with dial setting. Start with a
center dial setting. The draft fan cover also requires
experimenting with. Start with a 20% opening.
Set the furnace thermostat for comfort. Set the other
thermostat 10 degrees lower.
Use caution when opening loading door. Avoid open-
ing loading door rapidly. This could cause flames to
flash out the door. This occurs when there is unburned
fuel and a large amount of gases on the top of the
firebox. When the door is opened oxygen is combined
with the gases and ignites.
ASH REMOVAL
Every morning when there is just a bed of hot embers,
shake the grate very, very lightly.
Once every week or two, depending on how much fuel you
burn, ashes should be removed. Note: A 2" to 3" bed of
ashes will prolong wood burning and protect grates.
CAUTION
Never let ashes build up to grate level. This will re-
duce the life span of your grate, and void grate war-
ranty.
To remove ash pan simply open ash door and pull out your
ash pan. But remember, the ash pan can get very hot.
Dump ashes in a metal container with a lid and place on a
non-combustible surface.
CAUTION
Never use anything but a metal container to put your
ashes in. Every year fires are caused by emptying
ashes into cardboard boxes or paper bags.
MAINTENANCE
Keep chimney and flue pipe clean by cleaning at least twice
during a heating season.
CREOSOTE-
FORMATION AND NEED FOR
REMOVAL
When wood is burned slowly, it produces tar and other
organic vapors which combine with expelled moisture to
form creosote. The creosote vapors condense in the rela-
tively cool chimney flue of a slow burning fire. As a result,
creosote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected
at least twice monthly during the heating season to deter-
mine if a creosote buildup has occurred.
If creosote has accumulated, it should be removed to re-
duce the risk of a chimney fire.
CAUTION
If you have a chimney fire, we recommend the follow-
ing immediate actions:

Alert everyone in the house.
Shut any furnace doors, disconnect power to the
unit, and close any dampers. This should take no
longer than a few seconds.
Call the fire department.
