GENERALFURNACEOPERATION
Aer installation of the furnace is complete, it is ready for op-
eration. e Honeywell Limit Control, in conjunction with a
wall thermostat, operates the distribution blowers and the dra
blower on the front of the furnace. e limit control can be ad-
justed to your desired blower On/O times. e factory settings
are 100/150/200.
e wall thermostat setting operates the ON time of the dra
blower. If the temperature is below the setting on the wall ther-
mostat, the dra blower will come on. (Recommended setting at
5 to 10 degrees higher than other heating thermostats.)
e rst two set points on the limit control operates the distribu-
tion blower(s). When the furnace plenum reaches the second set
point on the limit control, the distribution blower(s) will come
on. If the temperature falls to the rst set point, the distribu-
tion blower(s) will shut-o. e rocker switch on the top of the
junction box gives you the option to run one blower or two. If
the switch is ON, both blowers will come on when the plenum
reaches the set temperature.
When the furnace reaches the third set point on the limit control,
the dra blower will shut-o. e dra blower will come back on
if the temperature falls below the setting on the wall thermostat.
TESTING
1. Check the dra blower by turning the room thermostat up
high enough so that the dra blower turns on. en lower
the thermostat setting until you hear it shut o.
2. Use a sheet of newspaper to test your dra by placing it in-
side the furnace and lighting it.
With completion of the tests above, you are ready to light the
furnace. Follow the operating steps.
STARTINGAWOODFIRE
UsingForcedAirDraft
e top down method of re building is recommended for this
appliance. Aer making sure that the stove air intake controls
are fully open (completely pull-out towards you), Place the larg-
est pieces of wood on the bottom, laid in parallel and close to-
gether. Smaller pieces are placed in a second layer, crossways to
the rst. A third layer of still smaller pieces is laid crossways to
the second, this time with some spaces between. en a fourth
layer of loose, small kindling and twisted newspaper sheets tops
o the pile.
Higher eciencies and lower emissions generally result when
burning air dried seasoned hardwoods, as compared to so-
woods or to green or freshly cut hardwoods.
DO NOT BURN:
1. Garbage;
2. Lawn clippings or yard waste;
3. Materials containing rubber, including tires;
4. Materials containing plastic;
5. Waste petroleum products, paints or paint thinners, or as-
phalt products;
6. Materials containing asbestos;
7. Construction or demolition debris;
8. Railroad ties or pressure-treated wood;
9. Manure or animal remains;
10. Salt water driwood or other previously salt water saturated
materials;
11. Unseasoned wood; or
12. Paper products, cardboard, plywood, or particleboard. e
prohibition against burning these materials does not pro-
hibit the use of re starters made from paper, cardboard,
saw dust, wax and similar substances for the purpose of
starting a re in an aected wood heater.
Burning these materials may result in release of toxic fumes or
render the heater ineective and cause smoke.
Dead wood lying on the forest oor should be considered wet,
and requires full seasoning time. Standing dead wood can usual-
ly be considered to be about 2/3 seasoned. Splitting and stacking
wood before it is stored accelerates drying time. Storing wood on
an elevated surface from the ground and under a cover or cov-
ered area from rain or snow also accelerates drying time. A good
indicator if wood is ready to burn is to check the piece ends. If
there are cracks radiating in all directions from the center then
the wood should be dry enough to burn. If your wood sizzles in
the re, even though the surface is dry, it may not be fully cured,
and should be seasoned longer
CAUTION: Never use gasoline, gasoline-type lantern fuel, kero-
sene, charcoal lighter uid, or similar liquids to start or “freshen
up” a re in the furnace. Keep all such liquids well away from the
furnace while it is in use.
1. Open spin dra cap on ash door.
2. Pull the slide bae rod to the front position.
3. Open the fuel load door and light re using kindling and
several sheets of newspaper, then close the furnace door.
e furnace door should remain closed for 5 to 10 minutes
in order to establish the re. If the re has established, you
are ready to load the furnace.
CAUTION: To prevent ame and smoke spillage, the slide bae
must be pulled out and the fuel door must be cracked for ten
seconds before being fully opened.
Do not over re your furnace! Aer you have become familiar
with its operating, you should know how much wood to use.
4. Load the furnace, close the load door and push the slide
Bae rod to rear.
5. Close the spin dra cap on ash door, leaving it cracked about
the diameter of a dime.
6. e forced air dra cycles on demand from the wall thermo-
stat. Setting the U.S. Stove thermostat four degrees higher
than your existing thermostat is recommended. In opera-
tion, the power dra blower will run until the U.S. Stove
thermostat temperature setting is reached. e dra regula-
tor on the forced air dra is preset at the factory and should
require no adjustment.
