4.5, “Minimum Clearances for Termination.

C. Constructing the Appliance Chase

NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on

carpeting, vinyl, or any combustible material other than
wood.

WARNING! Risk of Fire! Maintain specied air space

clearances to appliance and vent pipe:

• Insulation and other materials must be secured to prevent
accidental contact.

• The chase must be properly blocked to prevent blown

insulation or other combustibles from entering and

making contact with replace or chimney.

• Failure to maintain airspace may cause overheating and
a re.

A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.

NOTICE: Treatment of ceiling restops and wall shield

restops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.

NOTICE: Where required by code, install only sprinkler

heads with a sprinkler activation temperature classied

as Extra High.

• Sprinklers inside of chase: Keep sprinkler head away

from vent and chimney.

• Heat Management applications: Maintain 36 inches of
clearance to openings from which heat is discharged
such as convection slots, passive heat registers, heat
zone registers, etc. Refer to Section 6.B for Heat
Management options allowed for this appliance.

Chases should be constructed and insulated in the same
manner as the thermal envelope of the home based on
the code requirements for that climate zone to prevent air
leakage and draft problems. The chase is an extension of
the building thermal envelope.

To further prevent drafts and air leakage, the wall shield
and ceiling restops should be sealed with caulk with
a minimum of 300 ºF continuous exposure rating to
seal gaps. Gas line holes and other openings should

be sealed with caulk with a minimum of 300 ºF continu-

ous exposure rating or stu󰀨ed with unfaced insulation. If the
appliance is being installed on a cement surface, a layer of
plywood may be placed underneath to prevent conducting
cold up into the room.

Minimum height requirements for an exterior chase on a top-

vented appliance are shown in Figure 3.11. Reference Fig-

ure 4.5 for additional clearances.

D. Use of Elbows

Diagonal runs have both vertical and horizontal vent as-

pects when calculating the e󰀨ects. Use the rise for the
vertical aspect and the run for the horizontal aspect. See
Figure 4.6.

Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, one foot of diagonal is equal to 8-1/2 inch
(216 mm) horizontal run and 8-1/2 inch (216 mm) vertical
run. A length of straight pipe is allowed between two 45º
elbows. See Figure 4.6.

Figure 4.7 shows the vertical and horizontal o󰀨sets for
DVP or SLP elbows.

E. Use of Flex Vent (SLP-FLEX Series 6-5/8

Inch)

The ex vent must be supported with the spacing between
support intervals not exceeding 4 feet, with no more than
1/2 inch sag between supports.

A support is required at each change in venting direction,
and in any location where it is necessary to maintain the
necessary clearance to combustibles. A simple “up and
out” installation (Figure 4.8) requires only enough support
to maintain the necessary clearance to combustibles.

However, the vent attachment point and the restop loca-

tion are considered to be supports.

F. Vent Diagrams

General Rules:

• SUBTRACT 3 ft. from the total H measurement for each
90º elbow installed horizontally.

• SUBTRACT 1-1/2 ft. from the total H measurement for
each 45º elbow installed horizontally.

• Rear Vented: A maximum of three 90º elbows (or six 45º

elbows) may be used in any vent conguration. Some
elbows may be installed horizontally. See Figure 4.23
and 4.26.

• Top V ented: A maximum of four 90º elbows (or eight 45º

elbows) may be used in any vent conguration. Some
elbows may be installed horizontally. See Figure 4.19.

• Elbows may be placed back to back anywhere in the
system.

• Any 90º elbow may be replaced with two back to back

45º elbows.

• When penetrating a combustible wall, a wall shield
restop must be installed.

• When penetrating a combustible ceiling, a ceiling restop
must be installed.

• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.

• Horizontal termination cap should have a 1/4 inch
downward slant to allow any moisture in cap to be
released. See Figure 4.9.

Measuring Standards:

Vertical and horizontal measurements listed in the vent
diagrams and clearances for termination were made
using the following standards:

• Pipe measurements are shown using the e󰀨ective length
of pipe. See Section 12.A (Figure 12.1 for DVP, Figure

12.9 for SLP) for information on e󰀨ective length of pipe
components.

• Horizontal terminations are measured to the outside

mounting surface (flange of termination cap). See

Figure 4.10.

• Vertical terminations are measured to top of last section
of pipe. See Figure 4.11.

• Horizontal pipe installed level with no rise.

MEASURE TO SHADED SURFACE
(OUTSIDE MOUNTING SURFACE)

1/4 in. max.

Note: Use SLP Series

components only.

**Note: When using SLP-FLEX (6-5/8 in.) venting, there

MUST be a 25% reduction in total H when using ex vent.
See Figure 4.8.

WARNING *

Fire Risk.

• When using SLP-HRC-SS termination cap
on top vented replaces, a one foot minimum
vertical vent section is required before installing
rst elbow.
