MAINTENANCE
1. AT THE START OF THE HEATING SEASON...
• It is advisable to have your local furnace man
inspect and service your furnace for the coming heat-
ing season.
• The furnace, smoke pipe and chimney should be
cleaned and checked for repairs.
2. EMERGENCY STOPS
• Shut off all electrical power at the main electric
service entrance.
3. SMOKE PIPE, HEAT EXCHANGER AND SECOND-
ARY HEAT EXCHANGER
• Do not burn green or freshly felled wood. If you do,
creosote and soot may build-up in the chimney,
smoke pipe and secondary heat exchanger. This
should be checked and cleaned several times each
heating season.
4. Turn on regular (primary) furnace once every month
to make sure it is functioning properly.
CLEANING THE CHIMNEY, SMOKE PIPE AND HEAT
EXCHANGER
On a regular schedule, check for creosote and soot build-up
in the chimney, smoke pipe and heat exchanger. They must
be kept clean.
Steel brushes are the safest for cleaning metal surfaces.
Salt solutions and some chemicals may damage metal sur-
faces. When cleaning chimney, obtain a stiff steel brush with
an extension handle and insert brush into chimney from the
top. Continue brushing and sweeping downward until the full
length of the chimney is cleaned. Open the clean-out door at
the bottom of the chimney and sweep the debris into a plas-
tic bag or container. When cleaning the smoke pipe or the
heat exchanger, use a steel brush.
IN CASE OF CHIMNEY FIRE
1. Alert everyone in the house.
2. Call Fire Department immediately.
3. Shut any doors and air inlet dampers and draft control.
This should take no longer than a few seconds.
DO NOT use your furnace until a professional inspection
has been made of your furnace, smoke pipe and chim-
ney.
