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 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 (149 ºC) continuous exposure rating
to seal gaps. Gas line holes and other openings should
be caulked with caulk with a minimum of 300 ºF (149 ºC)
continuous exposure rating or stuffed with unfaced insula-
tion. If the appliance is being installed on a cement surface, a
layer of plywood may be placed underneath to prevent con-
ducting 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 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.

C. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP venting systems. Refer to Section
12.A for vent component information and dimensions.
DO NOT mix pipe, ttings or joining methods from differ-
ent manufacturers.
The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each
joint within the wall.
WARNING! Risk of Fire or Asphyxiation. This appli-
ance requires a separate vent. DO NOT vent to a pipe
serving a separate solid fuel burning appliance.
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 4.4.
Figure 4.5 shows the vertical and horizontal offsets for
DVP 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 for information on effective
length of pipe components.
• Horizontal terminations are measured to the outside
mounting surface (ange of termination cap) (see Figure
4.6).
• Vertical terminations are measured to top of last section
of pipe. See Figure 4.7.
• Horizontal pipe installed level with no rise.

General Rules:
• SUBTRACT 3 ft. (914 mm) from the total H measurement
for each 90º elbow installed horizontally.
• SUBTRACT 1-1/2 ft. (457 mm) 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 conguration. Some elbows may be
installed horizontally. See Figure 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 in. (6
mm) downward slant to allow any moisture in cap to be
released. See Figure 4.8.
WALL
1/4 in. max.
(6 mm)
WARNING
Fire Risk. Explosion Risk.
Do NOT pack insulation or other combustibles
between ceiling restops.
• ALWAYS maintain specied clearances around
venting and restop systems.
• Install wall shield and ceiling restops as speci-
ed.
Failure to keep insulation or other material away
from vent pipe may cause re.
WARNING
Fire Risk.
• When using DVP-HRC-SS and DVP-HRC-ZC-
SS termination caps on top vented replaces, a
6 inch minimum vertical vent section is required
before installing rst elbow.
