A
HEATING SYSTEM
Aluminized steel inshot burners,
direct spark ignition, electronic
flame sensor, combustion air
inducer, redundant automatic dual
stage gas valve with manual shut-
off.
Heat Exchanger
Tubular construction, aluminized
steel, life cycle tested.
Optional Stainless Steel Heat
Exchanger is required if mixed air
temperature is below 45°F.
Electronic Pilot Ignition
Electronic spark igniter provides
positive direct ignition of burners
on each operating cycle. The
system permits main gas valve to
stay open only when the burners
are proven to be lit. Should a
loss of flame occur, the gas valve
closes, shutting off the gas to
the burners. Ignition module has
LED to indicate status and aid in
troubleshooting.
Watchguard circuit on module
automatically resets ignition
controls after one hour of
continuous thermostat demand
after unit lockout, eliminating
nuisance service calls.
Ignition control is factory installed
in the controls section.
B
Limit Control
Factory installed, limit control
with fixed temperature setting.
Heat limit control protects heat
exchanger and other components
from overheating.
Safety Switches
Flame roll-out switch, flame sensor
and combustion air inducer proving
switch protect system operation.
