Combustion-air intake connection to ensure 
contaminant-free air (right or left side).

Burner sight glass for viewing burner flame.

Burner assembly (inside). Operates with energy-
saving inshot burners and hot surface igniter for safe, 
dependable heating.

Redundant gas valve. Safe and efficient. Features 1 gas 
control with 2 internal shutoff valves. Valve appearance 
varies with furnace model.

Vent outlet. Uses PVC pipe to carry flue gas from 
the furnace’s combustion system (right or left side).

Inducer motor. Pulls hot flue gases through the heat 
exchangers, maintaining negative pressure for added 
safety.

Blower access panel safety interlock switch.

Air filter and retainer (location in furnace may vary).

Condensate drain connection. Collects moisture 
condensed from burned gases for disposal into home 
drain system. (Location in furnace varies.)

Heavy-duty blower. Circulates air across the heat 
exchangers to transfer heat into the home.

Secondary condensing heat exchanger (inside). 
Wrings out more heat through condensation. 
Constructed with polypropylene-laminated steel to 
ensure durability.

Primary serpentine heat exchanger (inside). 
Stretches fuel dollars with the S-shaped heat-flow 
design. Solid construction of corrosion-resistant 
aluminized steel means reliability.

Furnace control board.

3-amp fuse provides electrical and component 
protection.

Status code light emitting diode (LED) on furnace control 
board. Status code light is for diagnosing furnace opera-
tion and service requirements.

Pressure switch(es) ensure adequate flow of flue 
gas through furnace and out vent system.

Rollout switch (manual reset) to prevent 
overtemperature.

Junction box for 115-v electrical power supply. (May be 
located on right or left side)

Transformer (24v) behind furnace control board  pro-
vides low-voltage power to furnace control board and 
thermostat.
