Operating Your Furnace; How To Care For Your Furnace - Williams AC2030 Owner's Manual

OPERATING
YOUR FURNACE
Operation Of Your Furnace
The furnace operates in the following sequence:
1. Switch on the Thermostat. The gas valve opens to allow
gas flow to the burner and the combustion fan starts to
supply combustion air to ignite the burner
2. Heat builds up in the furnace and starts the fan. The
heated air comes out the circulation fans.
3. When thermostat setting is reached, the gas valve stops
gas to the burner and the unit is shutoff.
WARNING: The surface of the furnace is hot during
operation. Keep children, clothing, furniture, and
flammable material away from it. Keep all access
doors and panels in place except for inspection and
maintenance. On new installations, the gas lines will be
filled with air and it may take several minutes to establish
the flame.
WARNING: Danger of property damage, bodily injury or
death. If the furnace overheats or fails to shut off, close
manual shutoff gas valve to the furnace before turning
off electrical power to the accessory fan.
IMPORTANT: KEEP BURNER AND CONTROL
COMPARTMENT CLEAN. BURNER IS INACCESSIBLE
AND CANNOT BE CLEANED UNLESS REPLACED
WARNING: OBSERVE ANY LOUD NOISE OR FLASH
BACK WHEN THE COMBUSTION IS INITIATED. IF IT
DOES, CONTACT THE REPRESENTATIVE
