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.
NOTICE: Where required by code, install only sprinkler
heads with a sprinkler activation temperature classied
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 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 caulked with caulk with
a minimum of 300 ºF continuous exposure rating to
seal gaps. Gas line holes and other openings should
be caulked with caulk with a minimum of 300 ºF continuous exposure rating or stued 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.
WARNING! Risk of Fire! Maintain specied 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.
NOTICE: Where required by code, install only sprinkler
heads with a sprinkler activation temperature classied
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.

D. Use of Elbows
Diagonal runs have both vertical and horizontal vent aspects when calculating the eects. Use the rise for the
vertical aspect and the run for the horizontal aspect. See
Figure 4.5.
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.

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.
• A maximum of three 90º elbows (or six 45º elbows) may
be used in any vent conguration. Some elbows may be
installed horizontally. For example, 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.

Top Vent—Horizontal Termination—Two 45º Elbows
Installation requirements to replace the rst 90º elbow
with two 45º elbows:
Figure 4.10
Note: The CD series replaces can adapt to SLP series
vent pipe, if desired.
When venting o the top of the unit, use a DVP-2SL adapter
and a minimum 48 inch vertical section of SLP series vent pipe.
A DVP-SLP24 adapter may also be used with a 24 inch
vertical section of SLP series vent pipe.
After the 48 inch vertical section, the venting table rules
must be followed. The rst 48 inch vertical section is NOT
counted as part of the vertical components in the table. It is
still counted as part of the overall maximum run. All venting
table rules for the vent run must still be followed.
WARNING
Fire Risk.
• When using DVP-HRC-SS and DVP-HRC-ZCSS termination caps on top vented replaces, a
6 inch minimum vertical vent section is required
before installing rst elbow.
Example: DVP pipe 3 ft. min. vertical = 11 ft. max. horizontal
SLP pipe 7 ft. min. vertical = 11 ft. max. horizontal
