TABLE 23

MINIMUM VENT PIPE LENGTHS

SLP99UHV

MODEL

MIN.EQUIV. VENT

LENGTH

EXAMPLE

070

15 ft*

5 ft. plus 2 elbows of

1-/12”, 2”, 2-1/2” or

3” diameter pipe

090, 110

5 ft. plus 2 elbows

of 2”, 2-1/2” or 3”

diameter pipe

*Any approved termination may be added to the minimum equivalent
length listed. Two 45 degree elbows are the equivalent to one 90 de-
gree elbow.

NOTE -

It is acceptable to use any pipe size which fits

within the guidelines allowed in TABLE 24.

NOTE -

The exhaust collar on all models is sized to ac-

commodate 2” Schedule 40 vent pipe. Contact the Appli

cation Department for more information concerning sizing

of vent systems which include multiple pipe sizes.

NOTE -

All horizontal runs of exhaust pipe must slope

back toward unit. A minimum of 1/4” (6mm) drop for each

12” (305mm) of horizontal run is mandatory for drainage.

NOTE -

Exhaust pipe MUST be glued to furnace exhaust

fittings.

NOTE -

Exhaust piping should be checked carefully to

make sure there are no sags or low spots.

Use the following steps to correctly size vent pipe diam-

eter.

IMPORTANT

Do not use screens or perforated metal in exhaust

or intake terminations. Doing so will cause freeze-

ups and may block the terminations.

Flue Coupling

The provided flue coupling must be attached to the ex

haust coupling on the furnace top panel. Use provided

bands. See steps below and FIGURE 25.

1 -

Remove the caution sticker from flue coupling .

2 -

Fully insert flue coupling with both bands loosely

attached on the furnace exhaust coupling.

3 -

Insert PVC exhaust pipe through flue coupling.

Ensure vent pipe is fully seated into exhaust

coupling. Tighten both top and bottom bands to 40

in lbs. See FIGURE 25.

Do not use glue flue.

FIGURE 25

Piping Size Process

Which style termination

being used?

Standard or

concentric?.

Which needs

most elbows?

Intake or

exhaust?

How many elbows?

Count all elbows inside

and outside house.

Desired pipe size?

Find max intake or

exhaust pipe length.

Includes all vent pipe and

elbows inside and outside

the house.

What is the altitude of

the furnace installation?

What is the

furnace capacity?
