How to Care for Your Furnace

WARNING: If flame appears abnormal, contact
the gas company
technician immediately.
FIGURE 37
Annual Upkeep Needed
It is recommended that a qualified service technician perform
these checks at the beginning of each heating season:
Cleaning Blower
Turn off electric power supply at the disconnect switch, fuse
box or service panel before servicing. For maximum motor life
of the optional blower, inspect the motor yearly and clean any
lint or dust from fan blades, fan motor and ventilating holes.
Vent System
Check the vent cap and tubes to be sure there are no blocked
inlet air or flue openings. The flow of combustion and
ventilation air must not be obstructed. Clean or replace before
using the furnace. On new installations, the gas lines will be
filled with air and may take several minutes to establish a pilot
flame.
Furnace Area
For better circulation and more effective heating, do not place
obstructive furniture closer than four feet to the front of the
cabinet or two feet to either side of the cabinet.
The furnace area must be kept clear and free from combustible
material, gasoline and other flammable vapor and liquids.
