BURNING WOOD OPERATING INSTRUCTIONS
When installation is complete, close the supply switch and turn the thermostat above room temperature.
Check to make sure the draft fan above the fire door is operating when the thermostat is set above room
temperature. The draft fan should be off when thermostat is set below room temperature. The maximum draft is not
to be more than .05” W.C. as damage may result to the furnace when operated as a gravity unit.
Adjust the blower speed of the existing furnace to give an adequate temperature rise. Under no circumstances
should the temperature rise be more than 80
o
F (27
o
C)
To start the fire, turn up the thermostat to Maximum setting to turn ON Forced Draft Fan. Place some newspaper
crumpled up in the bottom of the firebox on top of the minimum requirement of 2” of sand, ash or firebrick. Add
some small kindling and light the fire. When the fire starts add some larger pieces of kindling or wood until you
have a good fire. The idea is to ultimately end up with a good bed of ash and coals, which helps to maintain a good
controllable fire.
Return wood thermostat in main living space to regular setting.
When reloading the firebox there will be a build up of ash and coals from the previous fire. Rake the coals mixed
with ash to the front of the firebox which places the coals at the front. Throw in your wood and the fire should light
in a few minutes.
By means of slide plate A above the firedoor, you can control the amount of combustion air allowed into the fire
box. The position of slide plate A will vary with heat requirement, as well as size and type of wood being burnt.
Slide plates B and C should be open when burning wood. For added efficiency, when heating with oil only, close all
three slide plates and adjust your solid fuel thermostat to its lowest temperature setting.

When the firebox gets full of ash (within two inches of door level), some morning, before loading the firebox, push
or rake the coals to the rear of the firebox. Remove the ash from the front of the firebox using only the shovel
supplied for this purpose. When the ashes only are removed from the front, rake the coals from the back to the
front. Throw in your wood and the fire will again be burning in a few minutes. The fire burns best when the ashes
are 3” to 4” below the fire door level.
NOTES
Do not load wood higher than the firebox liner.
When opening the firedoor, do it slowly so you don’t pull smoke into your home.
It is recommended that a back up heating system be used during the mild fall and spring temperatures or else build
small, hot “quick burning” fires from larger pieces of kindling.
During the daily inspection, the firebox walls should be cleaned with the scraper to insure any deposits are
removed. This will improve heat transfer and operating efficiency of the furnace.
