NOTE:
If necessary the condensate trap may be installed
up to 5’ away from the furnace. Use PVC pipe to connect
trap to furnace condensate outlet. Piping from furnace must
slope down a minimum of 1/4” per ft. toward trap.
1. Determine which side condensate piping will exit the
unit, location of trap, field-provided fittings and length of
PVC pipe required to reach available drain.
2. Remove plug (Figure 43) from the cold end header box
at the appropriate location on the side of the unit. Install
field-provided 1/2 NPT male fitting into cold end header
box. Use Teflon tape or appropriate pipe dope.
3. Install the cap over the clean out opening at the base of
the trap. Secure with clamp. See Figure 46.
4. Install drain trap using appropriate PVC fittings, glue all
joints. Glue the provided drain trap as shown in Figure
46. Route the condensate line to an open drain.
Condensate line must maintain a 1/4” downward slope
from the furnace to the drain.
Do not use copper tubing or existing copper condensate
lines for drain line.
CAUTION
Condensate Piping
This unit is designed for either right or left side exit of
condensate piping in upflow applications. In horizontal
applications, the condensate trap must extend below the
unit. An 8” service clearance is required for the condensate
trap. Refer to Figure 45 for condensate trap locations.
5. Installed field provided vent on trap assembly as shown
in Figures 43 through 47. Trap must extend at least 1”
above the furnace condensate drain connection in upflow
applications and 4-1/2” above the bottom of the cabinet
in horizontal applications.
6. If unit will be started immediately upon completion of
installation, prime trap per procedure outlined in Unit
Start-Up section.
CONDENSATE TRAP AND PLUG LOCATIONS
(Unit shown in upflow position)
NOTE:
In upflow applications where side return air filter is installed
on same side as the condensate trap, filter rack
MUST
be installed
beyond condensate trap or trap must be relocated to avoid
interference.
