Maintenance instructions
caution
Before cleaning chimney, smoke pipe furnace, be sure to turn
off electrical power to furnace. Be sure wood fire is out and
inside of furnace is cool.
a. at the start of the heating season:
1. It is advisable to have a service technician inspect and
service your furnace for the coming heating season.
2. Furnace, smoke pipe and chimney should be cleaned
and checked for repairs.
b. emergency stops:
1. Cut off all electrical current to the furnace by turning
off electrical power in main fuse panel.
c. air filter:
1. Check and clean monthly. Change filter at least twice
a year.
d. blower motor:
1. Check belt for proper tension.
e. grates:
1. Keep ash drawer emptied. Failure to do this will cause
grates to warp.
f. smoke Pipe, chimney and furnace heat exchanger:
1. Do not burn green or freshly felled wood. If you do,
creosote and soot may build up in the chimney, smoke
pipe and furnace heat exchanger. This should be
checked and cleaned several times each heating sea-
son. Soot will act as an insulator which will cause less
heat to be transferred into your duct system thus reduc-
ing the efficiency of the wood being burned.
hoW to Prevent rust and corrosion
At the end of each heating season, clean heat exchanger and
ash pan thoroughly. Paint the inside of the heat exchanger with
automobile crankcase oil. This will decrease rusting caused by
summer moisture.
If black paint on firing door area wears or burns off , it can be re-
painted with a high temperature, flat black, air-drying paint.
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 noncombus-
tible floor or on the ground, well away from all combustible materi-
als, pending final disposal. If the ashes are disposed of by burial in
soil or otherwise locally dispersed, they should be retained in the
closed container until all cinders have thoroughly cooled.
cleaning the chiMneY, sMoke PiPe
and heat exchanger
Avoid chimney fires. On a regular schedule, check for creosote
and soot buildup in the 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 overfire your furnace. Do not burn anything that combusts in
seconds. Excessive flue temperatures may result, thereby igniting
creosote.
To clean the chimney, obtain a stiff brush with an extendible handle
and insert the brush into the chimney from the top. Continue
brushing and sweeping downward until entire length of chimney
is cleaned.
After cleaning, the debris will be at the bottom of the chimney at
the clean-out opening. Open the clean-out door and sweep the
debris out into a metal container.
The smoke pipe from the furnace to the chimney can be cleaned
with a steel brush.
The primary heat exchanger can be cleaned with any steel brush.
A furnace vacuum cleaner may be used.
in case of chiMneY fire
call the fire dePartMent iMMediatelY!
EXTINGUISH THE FIRE IN FURNACE BY SETTING THE
THERMOSTAT ALL THE WAY TO THE LEFT TO CLOSE
PRIMARY AIR DAMPER. EMPTY FIRE CHAMBER AND ASH
PAN INTO SAFE, FIREPROOF CONTAINER.
DO NOT USE YOUR FURNACE UNTIL A PROFESSIONAL
INSPECTION HAS BEEN MADE OF YOUR FURNACE,
SMOKE PIPE AND CHIMNEY.
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 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 to determine if a creosote
buildup has occurred.
If creosote has accumulated it should be removed to reduce the
risk of a chimney fire.
