C.Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and procedures.
D.Pressure Switch Tubing
The LOWER collector box pressure tube (pink label) is factory connected to the pressure switch for use when furnace is installed in UPFLOW applications. This tube MUST be disconnected, extended, rerouted, and then reconnected to the pressure switch in HORIZONTAL LEFT applications.
NOTE: See Fig. 9 or tube routing label on main furnace door to check for proper connections.
Modify tube as described below.
1.Disconnect collector box pressure tube (pink label) attached to pressure switch.
2.Use smaller diameter tube
3.Route extended tube:
a.Behind inducer housing.
b.Between blower shelf and inducer housing.
c.Behind inducer motor bracket.
d.Between inducer motor and pressure switch.
CAUTION: The condensate trap MUST be installed below furnace. See Fig. 4 for dimensions. The drain connection to condensate trap must also be properly sloped to an open drain.
NOTE: Vent pipe length is restricted to a minimum of 5 ft. (See Table 4.)
NOTE: A
V.HORIZONTAL RIGHT
A horizontal right furnace application is where furnace blower is located to the left of combustion and controls section of furnace, and conditioned air is discharged to the right.
CAUTION: Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in attic application or over a finished ceiling.
4.Determine appropriate length, cut, and reconnect tube to pressure switch connection labeled COLLECTOR BOX.
E.Condensate Trap Freeze Protection
Refer to Condensate Drain Protection section for recommenda- tions and procedures.
F.Construct a Working Platform
Construct working platform where all required furnace clearances are met. (See Fig. 3 and 10.)
NOTE: In Canada, installations shall be in accordance with current NSCNGPIC Installation Codes and/or local codes.
A.Condensate Trap Location
The condensate trap must be removed from the
