HOW TO PREVENT RUST AND CORROSION
At the end of each heating season, clean both primary
and secondary heat exchangers. Also, clean the ash pan
thoroughly. Paint the inside of the heat exchanger with
automobile crankcase oil. This will decrease rusting
caused by summer moisture.
The black paint on firing door area may wear or burn off.
It can be repainted with a high temperature, flat black,
air-drying paint.
CLEANING THE CHIMNEY, SMOKE PIPE AND HEAT
EXCHANGER
Avoid chimney fires. On a regular schedule, check for
creosote and soot buildup in chimney, smoke pipe, and
heat exchanger. They must be kept clean. Keep a
professional chimney sweep in mind if you have access
to one.
Steel brushes are the safest for cleaning metal surfaces.
Salt solutions and some chemicals may damage metal
surfaces. Do not over fire your furnace. Do not burn
anything that combusts in seconds. Excessive fuel
temperatures may result, thereby igniting creosote.
To clean the chimney, obtain a stiff brush with an
extendible handle. Then insert the brush into chimney
from the top. Continue the brushing and sweeping
downward until entire length of chimney is cleaned.
After cleaning chimney, debris will be at the bottom of
chimney at the clean-out opening. Open clean-out door
and sweep debris into a metal container.
The smoke pipe, from furnace to chimney, can be
cleaned with an 8-inch diameter brush. A smaller brush
can also be used.
For cleaning the secondary heat exchanger you can use
a steel brush. Use a 4 x 6” brush for the Eagle I - Husky
and a 3 x 8” brush for the Eagle II - Polar, with a
flexible steel handle. The primary heat exchanger
can be cleaned with any steel brush. A furnace vacuum
cleaner may be used.
NOTE: Soot will act as an insulator which causes
less heat to be transferred into your duct
system. It also causes more heat out your
chimney. Both reduce the efficiency of the
wood and fuel being burned.
CAUTION: Before cleaning chimney,
smoke pipe, and furnace, turn electrical
power off to furnace and other appliances
connected to chimney. Be sure wood fire is out and
inside of furnace is cool.

CAUTION: In case of chimney fire, call
the fire department immediately!
CAUTION: Extinguish the fire in the
furnace. Do this by setting the
thermostats all the way down to close
the primary air damper and oil burner. Empty fire
chamber and ash pan into safe, fireproof container.
NOTE: Do not use your furnace until a professional
inspection has been made. They should inspect
your furnace, smoke pipe and chimney.
DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight
fitting lid. The closed container of ashes should be
placed on a noncombustible floor or on the ground.
Place the container well away from all combustible
materials, pending final disposal. Ashes can be
disposed of by burial in soil or otherwise locally
dispersed. First, the ashes should be retained in the
container until all cinders have thoroughly cooled.
CREOSOTE-FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other
organic vapors. This combines with expelled moisture to
form creosote. The creosote vapors condense in the
relatively 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. This is to determine if a creosote buildup has
occurred.
If creosote has accumulated it should be removed to
reduce the risk of a chimney fire.
