4. From inside the casing, insert the formed grommet end of the elbow
through the 7/8-in. hole in the casing.
5. Pull the grommet through the casing from the outside until it is
seated in the hole.
6. Attach the plain end of the drain elbow to the outlet stub on the
drain trap. Secure the drain elbow to the trap with the spring clamp.

NOTE: Locate the plug that needs to be removed. Using a screw driver
or tool, place end against rim on plug. Tap on the butt end of screwdriver
or other tool to remove plug.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing, safety glasses and gloves when
handling parts, and servicing furnaces.

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
The remaining drain line can be constructed from field supplied 1/2-in.
CPVC or 3/4-in. PVC pipe, in compliance with local building codes. A
factory-supplied 1/2-in. CPVC to 3/4-in. PVC adapter is supplied in the
loose parts bag for use as required.
7. Install the adapter or connect the 1/2-in. CPVC pipe by sliding a
spring clamp over the open end of the grommet on the outside the
furnace casing.
8. Open the spring clamp and insert the long end of the adapter or the
1/2-in. CPVC pipe into the outlet stub on the drain tube.
9. Connect additional condensate piping to a code-approved drain, or
to a condensate pump approved for use with acidic furnace
condensate and compatible with mineral and vegetable oils, such as
canola oil.
Allow at least 1/4-in. per foot (20 mm per meter) of slope down and
away from the furnace in horizontal sections of drain line.
TIP FROM CONTRACTORS: Contractors have found that
temporarily removing the inducer assembly in upflow applications while
performing the steps, below, makes upflow left-side drain connections
easier.
For Left Side Condensate Drain Connection:
1. For left side condensate drainage, the drain line is routed from the
condensate trap, behind the inducer (upflow) or gas valve
(downflow) and out through the left side of the furnace casing. A
pre-formed 1/2-in. CPVC "Z-pipe" is provided with the furnace.
A11342A
The Z-pipe is long enough to extend across the casing for drain
connections.
2. Locate the Z-pipe. Remove the pre-formed drain elbow and four
spring clamps from the loose parts bag.
3. The Z-pipe is connected to the condensate trap and the outside of
the furnace by modifying the formed rubber drain elbow as shown
in Fig. 17.
4. Remove the formed grommet from the rubber drain elbow by
cutting the elbow along the vertical line located about 1-3/8 in. (35
mm) away from the formed grommet. See
DISCARD THE FORMED GROMMET OR THE RUBBER
ELBOW. Both of these pieces will be used.
