Main
Furnace
Sequence
of Norma! Operation
When the thermostat
calls for heat the blower motor
is energized
purging the
combustion chamber of any residual
fuel.
After
a few seconds of blower
operation the
gas
valve
opens
emitting
fuel to the combustion
chamber. The electronic
ignitor
then ignites
the fuel.
Failure to ignite
will result in the
gas valve shutting
off. The
blower will continue to run for
a few seconds and
then shut off.
Auxiliary
Furnace 3000
& 3300 Series
This unit is intended
to provide
additional heat to the
living room-
cockpit area on
extremely cold days. It is
completely independent
of
the main furnace. It
has its own thermostat
located above
the sofa.
Because of the compact
size this unit uses a pilot
light.
