LIGHTING INSTRUCTIONS
58
56
54
DO NOT attempt to manually light the burner.
53
Failure to follow this warning could result in property
51
damage, personal injury or death.
50
Lighting instructions appear on each unit. Each
installation must be checked out at the time of
initial start up to insure proper operation of all
components. Check out should include putting
the unit through one complete cycle as outlined
below.
Turn on the main electrical supply and set the thermo-
stat above the indicated temperature. The ignitor will
automatically heat, then the gas valve is energized to
permit the flow of gas to the burners. After ignition and
flame is established, the flame control module monitors
the flame and supplies power to the gas valve until the
thermostat is satisfied.
TO SHUT OFF
For complete shutdown: Move the control switch on the
main gas valve to the "OFF" position (See Figures 25
and 26). Disconnect the electrical supply to the unit.
If this is done during the cold weather months, provi-
sions must be taken to prevent freeze-up of all water
pipes and water receptacles.
Failure to follow this warning could result in property
damage.
Whenever your house is to be vacant, arrange to
have someone inspect your house for proper tem-
perature. This is very important in below freez-
ing weather. If for any reason your furnace
should fail to operate damage could result, such
as frozen water pipes.
