Getting Started
A. Design and Installation Considerations
WARNING! Risk of Fire or Explosion! Read all instruc-
tions before starting the installation.
Direct vent gas appliances are designed to operate with
all combustion air siphoned from outside of the building
and all exhaust gases expelled to the outside. No addi-
tional outside air source is required.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, re ocials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system conguration to be used.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Framing and nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualied
service technician, service agency or your dealer.
Installation and service of this appliance should be performed by
qualied personnel. Hearth & Home Technologies recommends
HHT Factory Trained or NFI certied professionals.
NOTICE: Surface temperatures listed above are taken with
a temperature measuring probe as prescribed by the test
standard used for appliance certication. Temperatures
on walls or mantels taken with an infrared thermometer
may yield increased temperatures of up to 30 °F (17 °C) or
more depending on the thermometer settings and material
characteristics being measured. Use appropriate nishing
materials that are able to withstand these conditions. For
additional nishing guidelines, see Section 10.

Notes:
1. These are good faith recommended clearances only and not a guarantee of compliance with all TV
manufacturers’ maximum allowable opera�ng temperatures.
2. Since every home has unique air flow characteris�cs and maximum allowable opera�ng temperatures
can vary from manufacturer to manufacturer and from model to model, actual TV temperatures should
be validated at the �me of each installa�on. TVs should not be used in situa�ons where the actual TV
temperature exceeds the manufacturers’ maximum allowable opera�ng temperatures iden�fied in the
TV’s technical specifica�ons. Contact the TV’s manufacturer directly if you cannot locate this
informa�on or have ques�ons regarding the informa�on.
3. Mantel height and depth must conform to mantel requirements specified in the appliance installa�on
manual.
4. “C” dimension taken from the top of the hood or appliance opening.
5.
Sugges�ons on how to further reduce TV temperatures:
a. Increase “A” dimension.
b. Increase “C” dimension, however, increasing “B” dimension beyond maximum recommended
typically results in higher temperatures.

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.
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 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.
Minimum height requirements for an exterior chase on a top-
vented appliance are shown in Figure 3.8. Reference Figure
4.5 for additional clearances.
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 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.

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 4.6.
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.

E. Vent Diagrams
General Rules:
• 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.
• It is recommended that the horizontal termination cap
have a 1/4 inch downward slant to allow any moisture
in cap to be released. See Figure 4.8.
If venting conguration diers from the vent diagrams on
the following pages (Figure 4.12-4.29), these rules also
apply:
• 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 such as in Figure 4.15.
• Elbows may be placed back to back anywhere in
the system.
• Any 90º elbow may be replaced with two back to
back 45º elbows.
• 2 x 45° elbow jog directly o the top of the replace
is allowed but has no V or H value, is permitted
when reducing to SLP pipe, and DOES NOT count
towards total elbow count.
To replace the rst starter elbow with two 45° elbows,
refer to Figure 4.8. All other 90° elbows can be replaced
with two 45° elbows.
Top Vent Horizontal Termination
Two 45° Elbows
Installation requirements to replace the rst 90° elbow
with two 45° elbows:
4 ft min.
(1.22 m)
16 ft max.
(4.87 m)
1/4 in. max.
(6 mm)
Figure 4.8
Note: Reference Figure 4.23 for
special instructions for use of 45º
elbow on rear vent appliances.
Note: The ST-DV36IN and PIER-DV36IN 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.
Example: DVP pipe 1 ft. min. vertical = 3 ft. max. horizontal
SLP pipe 5 ft. min. vertical = 3 ft. max. horizontal

Hearth & Home Technologies • PIER-DV36IN, ST-DV36IN Installation Manual • 2658-980 Rev. C • 4/22
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 eective length
of pipe. See Section 12.A (Figure 12.1 for DVP, Figure
12.8 for SLP) for information on eective 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.

Exhaust restrictors are recommended for these verti-
cally terminated products which have excessive draft.
Exhaust restrictors will compensate for high draft, and
restore visual ame height. If the vent conguration has
a total vertical of 10-60 feet, an exhaust restrictor may
be needed. The exhaust restrictor can be located in the
appliance manual bag.
Exhaust restrictor Instructions
1. Remove metal refractory panel and exhaust bae from
pilot side of appliance. To remove the refractory panel
use a 1/4 inch nut driver and remove the two screws
that secure it in place. To remove the exhaust bae,
remove the three screws securing it in place. See Figure

Figure 5.3 Wall Penetration
B. Wall Penetration Framing/Firestops
Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield restop(s). The wall shield
restop maintains minimum clearances and prevents cold
air inltration.
• The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
• SLP pipe - A wall shield restop must be placed on each
side of an interior wall. A minimum 1-1/2 in. (38 mm)
overlap of attached heat shields must be maintained.
• DVP pipe - A wall shield restop is required on one side
only on interior walls. If your local inspector requires a
wall shield restop on both sides, then both wall shield
restops must have a heat shield (refer to Section
12.A.) attached to them.
• See Section 7.F. for information for regarding the instal-
lation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-com-
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 restop is only required on one side and no heat
shield is necessary.
DO NOT PACK VENT FRAMING HOLE WITH INSULATION
OR OTHER MATERIAL.
Note: Center of the horizontal vent pipe to the vertical measuring surface of a
trap cap is 5 inches (127 mm).
