1. Combustion-air	intake connection to ensure	contaminant-	11. Everlastic	_'_Secondary	condensing		heat	exchanger (inside).
free air (right	or left side).		Wrings	out more heat	through	condensation.			Constructed
			with polypropylene-laminated			steel	to	ensure	durability.

2.Burner sight glass for viewing burner flame.

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

4.Redundant gas valve. Safe and efficient. Features 1 gas control with 2 internal shutoff valves and one throttling valve.

5.Vent outlet. Uses PVC pipe to carry flue gas from the

furnace's combustion system (right or left side).

6.Inducer motor. Pulls hot flue gases through the heat

exchangers, maintaining negative pressure for added safety.

7.Blower access panel safety interlock switch.

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

9.Condensate drain connection. Collects moisture condensed

from burned gases for disposal into home drain system. (Location in furnace varies.)

10.Heavy-duty blower. Circulates air across the heat

exchangers to transfer heat into the home.

12. Primary serpentine heat exchanger (inside). Stretches fuel

dollars with the S-shaped heat-flow design. Solid

construction of corrosion-resistant aluminized steel means reliability.

13.Furnace control board.

14.3-amp fuse provides electrical and component protection.

15.Light emitting diode (LED) on furnace control board. Status

code light is for diagnosing furnace operation and service requirements.

16.Pressure switches ensure adequate flow of flue gas through furnace and out vent system.

17.Rollout switch (manual reset) to prevent overtemperature.

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

19.Transformer (24v) behind furnace control board provides

low-voltage power to furnace control board and thermostat.
