ROOFTOP VENT TERMINAL INSTALLATION
(Fig- 3)
NOTE: The solid-line arrangement in Fig. 3 is the pre­
ferred arrangement; the dashed-line arrangement is an
option for the combustion-air pipe.
1. Remove one 90° elbow from elbow and bracket
assembly provided in kit. Loosen screw so other
elbow can turn.
2. Loosely install elbow with bracket on combustion-
air pipe.
3. Loosely install pipe coupling, provided in kit, on
properly cut vent pipe. Position coupling so that
bracket will mount as shown in Fig. 3.
4. Disassemble loose pipe fittings. Clean them and apply
cement using procedures described in Combustion-
Air and Vent Piping.
5. Install bracket as shown in Fig. 3.
6. For applications using combustion-air pipe option
(indicated by dashed lines in Fig. 3), install 180°
U-fitting on end of pipe instead of 90° elbow.
SIDEWALL VENT TERMINAL INSTALLATION ~
Install kit as follows when combustion-air and vent pipes
exit through sidewall 12 in. or more above highest anti­
cipated snow level or grade (Fig. 4).
NOTE: The solid-line arrangement in Fig. 4 is preferred.
The dashed-line arrangement is an option for the vent
pipe only.
Condensate Drain — Route the condensate to a
nearby floor drain or condensate pump. If a condensate
pump is required, it should have a corrosion-resistant
impeller and tank
The 1/2-in. diameter schedule 40 PVC and CPVC
condensate drain piping and fittings must conform to
ANSI standards and ASTM D2665 and D2946. The
schedule 40 PVC and CPVC cement and primer must
conform to ASTM F493 and D2564.
For proper condensate drainage, furnace must be
within 1/2-in. of level. Highest corner of furnace must
not be more than 1/2-in. above lowest corner.
NOTE: The furnace contains an internal condensate trap;
do NOT install external trap.
1. Determine the side of furnace from which drain will
exit. Cut and prcassemble drain piping (field supplied)
directly to an open drain. Refer to Combustion-Air
and Vent Piping for instructions on preparing and
cementing plastic pipe
2. Cement elbow on pipe assembly (factory supplied)
to condensate trap mounted on blower housing.
3. Using a second wrench to hold assembly, attach first
section of field-supplied drain pipe to compression
coupling provided.
4. When using schedule 40 PVC drain pipe, connect
adapter provided to end of pipe installed in compres­
sion fitting.
5. Attach field-supplied schedule 40 PVC adapter to
threaded factory adapter.
6. Cement remaining pipe joints.
1. Loosely install elbow and bracket assembly on
combustion-air and vent pipes.
2. Remove and disassemble elbow and bracket assembly.
3. Install elbows as shown in Fig. 4. Clean them and
apply cement using procedures described in
Combustion-Air and Vent Piping.
4. Install bracket as shown in Fig. 4.
5. Position vent-pipe assembly, maintaining a 12-in.
separation. Cement vent pipe in elbow as shown in
Fig. 4.
6. For applications using vent-pipe option (indicated by
dashed lines in Fig. 4), rotate elbow 90° from position
shown.
Install kit as follows when combustion-air and vent
pipes exit through sidewall less than 12 in. above highest
anticipated snow level or grade (Fig. 5):
NOTE: The solid-line arrangement in Fig. 5 is preferred.
The dashed-line arrangement shown is an option for
the vent pipe only.
1. Disassemble elbow and bracket assembly.
2. Loosely install bracket on 180° U-fitting
3. Loosely install coupling on end of vent pipe.
4. Loosely install U-fitting and bracket as shown in
Fig. 5. Position U-fitting so that open end is against
structure wall.
5. Loosely install vent-pipe assembly in coupling as
shown in Fig. 5.
6. Check required dimensions as shown in Fig. 5.
7. Disassemble loose pipe fittings. Clean them and apply
cement using procedures described in Combustion-Air
and Vent Piping.
8. Install bracket as shown in Fig. 5.
ELECTRICAL CONNECTIONS
IMPORTANT: Before proceeding with the electrical
connections, make certain that voltage, frequency, and
phase correspond to those values specified on the unit
rating plate. Also, check that service provided by utility
is sufficient to handle load imposed by this equipment.
Refer to unit rating plate for equipment electrical
requirements.
Consult the specific furnace installation instructions
for wiring diagrams which show the proper field high-
and low-voltage wiring. Make all connections in accord­
ance with the National Electrical Code and any local
codes and ordinances that might apply.
A WARNING
The cabinet must have an uninterrupted or unbroken
ground according to the National Electrical Code,
ANSI/NFPA 70-1984, and local codes to minimize
personal injury if an electrical fault should occur
Ground may consist of electrical wire or metallic
conduit approved for electrical ground when in­
stalled in accordance with existing electrical codes
Do NOT use gas supply piping as an electrical
ground
A CAUTION
If manual disconnect switch is to be mounted on the
furnace, select a location where drill or fastener will
not contact electrical or gas components
NOTE Use only copper conductors between disconnect
switch and furnace.
Check all electrical connections (both factory and
field) for tightness Repeat check after unit has reached
operating temperatures.
