C. Constructing the Appliance Chase
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.
Chases should be constructed in the manner of all out-
side walls of the home to prevent cold air drafting prob-
lems. The chase should not break the outside building
envelope in any manner.
Walls, ceiling, base plate and cantilever oor of the chase
should be insulated. Vapor and air inltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air inltration may be an issue, the inside surfaces may be
sheetrocked and taped (or an equivalent method may be
used) to achieve maximum air tightness.
To further prevent drafts, the wall shield and ceiling re-
stops should be caulked with caulk with a minimum of
300ºF continuous exposure rating to seal gaps. Gas
line holes and other openings should be caulked with
caulk with a minimum of 300ºF continuous exposure rating
or stuffed 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.
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.
NOTICE: When installing a sprinkler head in a replace
chase, it is recommended to use a sprinkler head with a
sprinkler activation temperature classied as Extra High.
Keep sprinkler head away from vent and chimney.
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 could cause overheating
and a re.

D. Use of Elbows
Diagonal runs have both vertical and horizontal vent as-
pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect. See
Figure 4.4.
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 in. (216
mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A
length of straight pipe is allowed between two 45º elbows.
See Figure 4.5.
Figure 4.6 shows the vertical and horizontal offsets for
DVP or SLP elbows.

E. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards:
• Pipe measurements are shown using the effective length
of pipe. See Section 12.A (Figure 12.1 for DVP, Figure
12.6 for SLP) for information on effective length of pipe
components.
• Horizontal terminations are measured to the outside
mounting surface (ange of termination cap) (see Figure
4.7).
• Vertical terminations are measured to top of last section
of pipe. See Figure 4.8.
• Horizontal pipe installed level with no rise.

F. Use of Flex Vent (SLP-FLEX
Series 6-5/8 Inch)
The ex vent must be supported with the
spacing between support intervals not ex-
ceeding 4 feet, with no more than ½ 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 4.9) requires
only enough support to maintain the neces-
sary clearance to combustibles. However,
the vent attachment point and the restop
location are considered to be supports.

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 4.24
and 4.25.
• Top Vented: 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 4.17
and 4.18.
• 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 4.10.
