CAUTION: MINOR PROPERTY DAMAGE
Failure to follow this caution may result in minor
property damage.
Local codes may require a drain pan under entire furnace
and condensate trap when a condensing furnace is used in
an attic application or over a finished ceiling.
NOTE: In Canada, installations shall be in accordance with
current NSCNGPIC and/or local codes.
A. Condensate Trap Location
The condensate trap must be removed from the factory-installed
blower shelf location and relocated in selected application location
as shown in Fig. 2 or 11.
To relocate condensate trap from the blower shelf to desired
location, perform the following:
1. Remove 3 tubes connected to condensate trap.
2. Remove trap from blower shelf by gently pushing tabs
inward and rotating trap.
3. Remove casing hole filler cap from casing hole. (See Fig. 2
or 11.)
4. Install casing hole filler cap (factory-supplied in loose parts
bag) into blower shelf hole where trap was removed.
