PERSONAL IN !! RY HAZARD
(aution should be taken to prevent draining where slippery
conditions could cause personal injuries.
Excessive condensate draining may cause saturated soil
conditions which could result in damage to plants.
( ONDENSATE DRAIN PROTE(TION
Freezing condensate left in condensate trap and drain line may
cause cracks, and possible water damage may occur. If t'reeze
protection is required, use condensate t'reeze protection accessory
or equivalent 3 to 6 watt per ft at 120v and 40°F self:regulating,
shielded, and waterproof heat tape. See Installation Instructions
supplied with accessory or heat tape manui:acturer's recommenda=
tions
1. Fold heat tape in halt" and wrap on itself" 3 times.
2. Locate heat tape between sides of condensate tlap back. (See
Fig. 47.)
3. _se wire ties to secure heat tape in place Wire ties can be
positioned in notches of condensate trap sides (See Fig. 47.)
4. Wrap field &ain pipe with remaining heat tape, approximately
1 wrap per it.
5. When using field=supplied heat tape, fbllow heat tape nranu=
_hcmre*'s instructions for all other installation guidelines.
START-UP, ADJUSTMENT AND SAFETY CHECK
Step 1--General
1. Furnace nmst have a 115-v powei supply properly connected
and grounded Proper polarity must be maintained for cmTect
operation.
NOTE: Proper pola*iw must be maintained for 115=v wiring It"
polarity is incorrect, control center LED status indicator light will
flash rapidly and furnace will not ope*ate
2. Thermostat wire connections at terminals R, W, G, and Y
n-rest be made at 24-v terminal block on fi/rnace control center
3. Natural gas sela'ice pressure must not exceed 05 psig (14=in
wc), but must be no tess than 016 psig (4 5-in wc).

4. Blower access panel must be in place to complete ll5-v
electrical circuit to filmace
UNIT MAY NOT OPERATE
Failure to _bltow this caution may result in intermittent nnit
operation.
These t:urnaces are equipped with a manual reset limit switch
in burner box. This switch will open and shut power to gas
valve if an overheat condition (flame rollout) occurs in burner
enclosure Correct inadequate combustion-air supply or in>
proper venting condition and reset switch. DO NOT jumper
this switch.
Be_:bre operating furnace, check flame rollout manual reset switch
for continuity. If necessa_, press button to reset switch
Step 2--Prime Condensate Trap with Water
UNIT MAY NOT OPERATE
Failure to %llow this caution may result in intem_ittent nnit
operation.
Condensate trap must be PRIMED or proper draining may not
occur The condensate trap has 2 internal chambers which can
ONLY be primed by pouring water into the inducer drain side
of condensate t_ap.
1. Remove upper inducer housing &ain connection cap. (See
Fig. 48.)
2. (onnect field=supplied 1/2=in. ID robe to upper inducer
housing &ain connection.
3. Insert field=supplied Nnnel into tube.
4. Pour 1 quart of water into Nnnetitube. Water should run
through inducer housing, overfill condensate trap, and flow
into open field drain. (See Fig. 490
5. Remove Nnnel and robe from inducer housing and replace
&ain connection cap and clamp
