Gas valve. Safe, efficient. Features 2 separate gas
shut-off valves.
Burner assembly (inside). Operates with energy
saving pilot, inshot burners, and spark igniter
for safe, dependable heating.
Primary serpentine heat exchanger (inside).
Stretches fuel dollars with the S-shaped heat-
flow design. Solid construction of corrosion-
resistant aluminized steel means reliability.
Secondary condensing heat exchanger (inside).
Wrings out more heat through condensation.
Constructed with polypropylene-laminated steel
to ensure durability.
Inducer motor. Pulls hot flue gases through the
heat exchangers, maintaining negative pressure
for added safety.
Vent outlet. Uses PVC pipe to carry vent gases
from the home.
Condensate drain trap. Collects moisture
condensed from burned gases for disposal into
home drain system.
Heavy-duty blower. Circulates air upwards,
scrubbing the heat exchangers to speed
condensation and transfer extra heat into the
home.
Air filter and retainer spring.
Light emitting diode (LED) view port. Fault
code lights are inside.
Low-voltage circuit breaker.
