STANDING PILOT MODELS

3508631; 3508632; 5008631; 5008632; 6508631; 6508632

NOTE:

For models equipped with WILLIAMS gas valve P323209 or

P322042 refer to this page and page 23 for "SAFETY &

LIGHTING INSTRUCTION" and "TURN GAS OFF TO

APPLIANCE."

On new installations, the gas lines will be filled with air and it may

take several minutes to establish the pilot flame.

Keep all access doors and panels in place except for inspection

and maintenance.

WARNING: The surface of the furnace is hot during

operation. Keep children, clothing, furniture, and

flammable material away from it.

Do not store or use gasoline or other flammable

liquids or vapors near the furnace.

SAFETY CONTROLS

These furnace are protected against unsafe operation by five

automatic safety controls: (1) A safety pilot acts to shut OFF the

gas valve in case of pilot failure; (2) A redundant gas valve; (3) A

limit switch shuts down the main burner to prevent overheating

the furnace cabinet; (4) A vent safety shutoff device shuts down

the main burner to protect against improper venting of combustion

products. These limit switches will reset when furnace cools; and

(5) A thermal overload protects the motor against burnout caused

by current surges or if anything should block the flow of air

through the furnace. This switch will reset itself when the motor

cools down and it cannot be adjusted.

WARNING: Danger of ignition flash and eye injury

or blindness.

Protect your eyes. Never attempt to light pilot with

gas control valve knob in "on" position. Flashback

could occur.

NOTE:

Models 3508631; 3508632 are equipped with a single speed fan.

TWO-SPEED FAN OPERATION

MODELS: 5008631; 5008632; 6508631; 6508632

For models equipped with WILLIAMS gas valve P323209 or

P322042: Blower will first operate at low speed then shift to high

speed as the furnace heats up.

IMPORTANT

KEEP BURNER AND CONTROL COMPARTMENT CLEAN.

WARNING: Danger of property damage. Bodily

injury or death

If the furnace overheats or fails to shut off, close

manual gas valve for the furnace before turning off

the electric power.

ELECTRONIC IGNITION MODELS*

3508231; 3508232; 5508231; 5508232

NOTE:

For models equipped with WILLIAMS gas valve P323209 or

P322042 refer to this page and page 23 for "SAFETY &

LIGHTING INSTRUCTION" and "TURN GAS OFF TO

APPLIANCE."

THE FURNACE WORKS LIKE THIS:

1. Thermostat turns on the control module.

2. Automatic relight system (in module) opens gas valve and

electronically ignites pilot. After pilot flame has been

established and proven by the control module, the main valve

circuit opens and pilot lights main burners.

3. Heat builds up in the furnace and starts the fan. The heated air

comes out the front bottom louvered panel at floor level.

4. When the thermostat setting is reached, it shuts off the main

burner.

5. The fan runs until the heat is removed from furnace, then it

turns off.

IMPORTANT

KEEP BURNER AND CONTROL COMPARTMENT CLEAN.

SAFETY LIMIT CONTROL

These furnaces are protected against unsafe operation by three

automatic safety controls: (1) The electronic ignition system; (2) A

limit switch shuts down the main burner to prevent overheating

the furnace cabinet; this limit switch will reset when furnace cools;

(3) A thermal overload protects the motor against burnout caused

by current surges or if anything should block the flow of air

through the furnace, the switch will turn the main burner off. When

motor cools down, this switch will reset itself. This switch cannot

be adjusted.

WARNING: Danger of ignition flash and eye injury

or blindness. Protect your eyes. Never attempt to

light pilot with gas control valve knob in "on"

position. Flashback could occur.

NOTE

Models 3508231; 3508232 are equipped with a single speed fan.

TWO-SPEED FAN OPERATION MODELS: 5508231; 5508232

Blower will first operate at low speed then shift to high speed as

the furnace heats up.

WARNING: The surface of the furnace is hot during

operation. Keep children, clothing, furniture, and

flammable material away from it.

On new installations the gas lines will be filled with air and it may

take several minutes to establish the pilot flame.
