14. S ecure the grommet tothe Z-pipe with the spring c lamp.
The remaining drain linecan beconstructed from fieldsupplied

building codes. A factory-supplied l/2-in.CPVC to3/4-in. PVC
adapter issupplied inthe loose p arts bag foruse as required.
15. I nstall theadapter orconnect thel/2-in.CPVC pipe by
sliding a spring c lamp over the open e nd ofthe grommet on
the outside the furnace casing.
16. O pen thespring clamp and insert t helongendof the

drain t ube.
17. C onnect additional condensate piping toacode-approved
drain, ortoacondensate pump a pproved foruse withacidic
furnace c ondensate andcompatible with mineral and
vegetable oils, s uch a s canola oil.
Allow at least l/4-in. (6 mm) per foot of slope away from the fur-
nace in horizontal sections of drain line.
Horizontal Orientation
1. In the Horizontal orientation, a field supplied accessory
drain trap grommet is required to seal the gap between the
casing and the condensate trap for direct vent applications,
only. The grommet is NOT required for single-pipe, or oth-
er non-direct-vent applications.
2. The condensate trap outlet extends 2 in. (51 ram) below the
furnace casing. To allow for servicing the trap, the
condensate drain tube in the loose parts bag can be modified
to make a coupler to allow for future service of the
condensate trap and drain line.
3. Remove the knock-out for the condensate trap in the side of
the casing.
4. Install the drain trap grommet in the casing if required for
direct vent applications. If necessary, remove the trap, install
the grommet and re-install the trap.
5. Remove the pre-formed rubber drain elbow, and two spring
clamps from the loose parts bag.
6. Remove the formed grommet on the elbow to create an
elbow or straight connector. (See Fig. 15.)
7. Connect the cut elbow or grommet to the outlet of the
condensate trap with 1 spring clamp.
The remaining drain line can be constructed from field-supplied
l/2-in. CPVC or 3/4-in. PVC pipe, in compliance with local build-
ing codes. A factory-supplied l/2-in. CPVC to 3/4-in. PVC adapter
is supplied in the loose parts bag for use as required.
8. Install the adapter or connect the l/2-in. CPVC pipe by
sliding a spring clamp over the open end of the elbow or
grommet on the outside the furnace casing.
9. 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.
10. 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. (6 ram) per foot of slope away from the
furnace in horizontal sections of drain line.
CUT HAZARD
Failure to follow this caution may result in personal iniury.
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.
