CHECK

NOTICE

IMPORTANT INSTALLATION AND START

UP

PROCEDURES

Failure to follow this procedure may result in a nuisance

smoke or odor complaint.
The manifold pressure, gas rate by meter clocking,

temperature rise and operation must be checked after

installation. Minor smoke and odor may be present

temporarily after start

up from the manufacturing process.

Some occupants are more sensitive to this minor smoke and

odor. It is recommended that doors and windows be open

during the first heat cycle.

General

1. Furnace must have a 115-v power supply properly

connected and grounded.

NOTE

:  Proper polarity must be maintained for 115-v wiring.

Control status indicator light flashes rapidly and furnace
does not operate if polarity is incorrect or if the furnace is not
grounded.

2. Thermostat wire connections at terminals R, W, G,

and Y must be made at 24-v terminal block on

furnace control.

3. Natural gas service pressure must not exceed 0.5

psig (14- in. w.c., 1125 Pa), but must be no less than

0.16 psig (4.5-in. w.c., 350 Pa).

4. Blower door must be in place to complete 115-v elec-

trical circuit and supply power to the furnace

components.

UNIT OPERATION HAZARD

Failure to follow this caution may result in intermittent

unit operation or performance satisfaction.
These furnaces are equipped with a manual reset limit

switch in burner assembly.  This switch opens and

shuts off power to the gas valve if an overheat

condition (flame rollout) occurs in the burner

assembly/enclosure.  Correct inadequate

combustion

air supply, improper gas pressure setting,

improper burner or gas orifice positioning, or improper

venting condition before resetting switch.  DO NOT

jumper this switch.

CAUTION

!

Before operating furnace, check flame rollout manual reset

switch for continuity. If necessary, press button to reset

switch.
EAC-1 (115vac) terminal is energized whenever blower

operates. HUM (24vac) terminal is only energized when the

low pressure switch (LPS) is closed on a call for heat.

Prime Condensate Trap with Water

CARBON MONOXIDE POISONING HAZARD

Failure to follow these warnings could result in personal

injury or death.
Failure to use a properly configured trap or NOT

water-priming trap before operating furnace may allow

positive pressure vent gases to enter the structure

through drain tube. Vent gases contain carbon

monoxide which is tasteless and odorless.

!

WARNING

1. Remove upper and middle collector box drain plugs

opposite of the condensate trap.   (See Figure 10.)

2. Connect field-supplied 5/8-in. (16 mm) ID tube with at-

tached funnel (see Figure 10) to upper collector box

drain connection.

3. Pour one quart (liter) of water into funnel/tube. Water

should run through collector box, overfill condensate

trap, and flow into open field drain.

4. Remove funnel; replace collector box drain plug.
5. Connect field-supplied 5/8-in. (16 mm) ID tube to

middle collector box drain port.

6. Pour one quart (liter) of water into funnel/tube. Water

should run through collector box, overfill condensate

trap, and flow into open field drain.

7. Remove funnel and tube from collector box and

replace collector box drain plug.

Purge Gas Lines

If not previously done, purge the lines after all connections

have been made and check for leaks.

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal

injury, death, and/or property damage.
Never purge a gas line into a combustion chamber.

Never test for gas leaks with an open flame. Use a

commercially available soap solution made

specifically for the detection of leaks to check all

connections.  A fire or explosion may result causing

property damage, personal injury or loss of life.

!

WARNING

Adjustments

FIRE HAZARD

Failure to follow this warning could result in personal

injury, death and/or property damage.
DO NOT bottom out gas valve regulator adjusting

screw. This can result in unregulated manifold

pressure and result in excess overfire and heat

exchanger failures.
