A. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP and SLP venting systems. Refer to
Section 16.B for vent component information.
DO NOT mix pipe, fittings 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.
7Vent Information and Diagrams
C. 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 7.1).
Two 45º elbows may be used in place of one 90º elbow. On
45º runs, one foot of diagonal is equal to 216 mm horizontal
run and 216 mm vertical run. A length of straight pipe is
allowed between two 45º elbows (see Figure 7.1).
Figure 7.1
B. Vent Table Key
The abbreviations listed in this vent table key are used in
the vent diagrams.
D. 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 Figure 7.2 and 7.3).
• Measurements are made from the appliance outer wrap,
not from the standoffs.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap).
• Vertical terminations are measured to bottom of
termination cap.
• Horizontal pipe installed level with no rise.

Top Vent - Vertical Termination
This model is approved to use DVP or SLP Series flue
pipe components. A DVP-TVHW or SLP-TVHW vertical
Termination Cap must be used to terminate flue systems
in a vertical position.
Approved flue system components are labeled for identifi-
cation. NO OTHER FLUE SYSTEMS OR COMPONENTS
MAY BE USED. Detailed installation instructions are in-
cluded with each flue termination kit and should be used
in conjunction with this manual.
WARNING! Risk of Fire! This gas appliance and flue
assembly must be flued directly to the outside and must
never be attached to a chimney serving a separate solid
fuel burning appliance. Each gas appliance must use a
separate flue system-common flue systems are prohibited.
CAUTION! Risk of Fire! Under no condition should com-
bustible material be closer than 3 inches (2-1/2 inches at
wall firestops) from the top of the 8 inch pipe or 1 inch to
the sides and the bottom for horizontal sections of this
flue system. Vertical sections of this system require a
minimum of 1 inch clearance to combustible materials all
around the 8 inch pipe.
For alternative installations, other than depicted, contact
your dealer for further information.

Flue System Approvals And Installations
These models have flue starting collars on both the top
and the back of the unit. Depending upon the installation,
decide which ONE set of starting collars will be used to at-
tach the flue system. The starting collar sealing cap must
remain on the starting collar NOT used.
These models use DVP and SLP series direct flue com-
ponents when using the TOP flue collars and DVP-series
direct flue components when using the REAR flue collars.
Approved flue system components are labeled for identi-
fication. NO OTHER FLUEING SYSTEMS OR COMPO-
NENTS MAY BE USED. Detailed installation instructions
are included with each flue termination kit and should be
used in conjunction with this manual. Figure 7.9 shows
flue system components and terminations.
Identifying Flue Components
The flue systems installed on this gas heater may include
one, two, or three 90° elbow assemblies. The relationships
of vertical rise to horizontal run in flue configurations using
90° elbows MUST BE strictly adhered to. The rise to run
relationships are shown in the flueing drawings and tables
on the next few pages.
WARNING! Risk of Fire! This gas appliance and flue as-
sembly must flue directly to the outside and must never
be attached to a chimney serving a separate solid fuel
burning appliance. Each gas appliance must use a sepa-
rate flue system-common flue systems are prohibited.
CAUTION! Risk of Fire! Under no condition should com-
bustible material be closer than 76 mm at wall fire-stops
from the top of the pipe or 25 mm to the sides and the
bottom for horizontal sections of this flue system. Verti-
cal sections of this system require a minimum of 25 mm
clearance to combustible materials all around the pipe.

A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
• Between ceiling firestops
• Between wall shield firestops
• Around vent system
Failure to keep insulation or other material away from
vent pipe may cause over heating and fire.
8Vent Clearances and Framing
Figure 8.2 Wall Penetration
* Shows center of vent framing hole for top or rear venting. The center of the
hole is one 25.4 mm above the center of the horizontal vent pipe.
Figure 8.1 Horizontal Venting Clearances To Combustible
Materials
B. Wall Penetration Framing
Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield firestop(s). The wall shield
firestop maintains minimum clearances and prevents cold
air infiltration.
• The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
• DVP pipe - A wall shield firestop is required on one side
only on interior walls. If your local inspector requires a
wall shield firestop on both sides, then both wall shield
firestops must have a heat shield (refer to Section
16.B.) attached to them.
• SLP pipe - A wall shield firestop must be placed on each
side of an interior wall. A minimum 1-1/2 inch (38 mm)
overlap of attached heat shields must be maintained.
• See Section 10.H. for information for regarding the in-
stallation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by noncom-
bustible materials such as concrete, a hole with diameter
one inch greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield firestop is only required on one side and no heat
shield is necessary.
* When using SLP or SL-D pipe, minimum clearances from the vent pipe to combus-
tible materials at inside wall firestops are: Top: 2-1/2 in. (64 mm)
Bottom: 1/2 in. (13 mm)
Sides: 1 in. (25 mm)
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
•DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick.
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If
wall thickness is greater than 7-1/4 in. a DVP-HSM-B will be required.
•SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to
194 mm thick).
• If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed.
If wall thickness is greater than 7-5/8 in. a DVP-HSM-B will be required.

A ceiling firestop MUST be used between
floors and attics.
•DVP pipe only - Frame an opening 10 in.
by 10 in. (254 mm by 254 mm) whenever
the vent penetrates a ceiling/floor (see
Figure 8.3).
•SLP pipe only - Frame opening 9 in. x 9
in. (229 mm x 229 mm) whenever the vent
penetrates a ceiling/floor (see Figure 8.3).
• Frame the area with the same sized lumber
as used in ceiling/floor joist.
• The ceiling firestop may be installed above or
below the ceiling joists when installed with a
attic insulation shield. It must be under joists
between floors that are not insulated. Refer

D. Install Attic Insulation Shield
WARNING! Fire Risk. DO NOT allow loose materials or
insulation to touch vent. Hearth & Home Technologies
Inc. requires the use of an attic shield.
The National Fuel Gas Code ANSI Z223.1 and NFPA 54
requires an attic shield constructed of 26 gauge minimum
metal that extends at least 2 in. (51 mm) above insulation.
Attic shields must meet specified clearance and be se-
cured in place.
Flat Ceiling Installation
• Remove one shield from box.
NOTICE: Cut previously installed batt insulation to make
room for the attic insulation shield.
• Wrap shield around pipe if pipe is already installed in
area to be insulated.
• Match the three holes in each side and fasten with three
screws to form a tube.
• Bend three tabs on the bottom of the shield outward to
allow attachment to the ceiling firestop.
• Bend the remaining bottom tabs inward 90º to maintain
the air space between the pipe and the shield. Set the
shield on the ceiling firestop and attach to the firestop.
• Bend all tabs inward 90º around the top of the shield.
These tabs must be used to prevent blown insulation
from getting between the shield and vent pipe, and to
maintain air space clearance.

E. Installing the Optional Heat-Zone-240V Kit
• Remove the knockout from the fireplace and discard it
(see Figure 8.6).
• Center the duct collar around the exposed hole and
attach it to the fireplace with 3 screws. Note: Do this
BEFORE final positioning of fireplace.
• Determine the location for the air register/fan housing
assembly.
Reference the Heat-Zone-240V Kit instructions for the
remaining installation steps.
Vaulted Ceiling Installation
• Remove one shield from box.
NOTICE: Cut previously installed batt insulation to make
room for the attic insulation shield.
• Cut the attic insulation shield (if application is for vaulted
ceiling) to fit your ceiling pitch. Snip cut edge to recreate
1 in. bend tabs all the way around the bottom.
• Wrap shield around pipe if pipe is already installed in
area to be insulated.
• Match the three holes in each side and fasten with three
screws to form a tube.
• Bend three tabs on the bottom of the shield outward to
allow attachment to the ceiling firestop.
• Bend the remaining bottom tabs inward 90º to maintain
the air space between the pipe and the shield. Set the
shield on the ceiling firestop and attach to the firestop.
• Bend all tabs inward 90º around the top of the shield.
These tabs must be used to prevent blown insulation
from getting between the shield and vent pipe, and to
maintain air space clearance.
