vent terminal and clearances. Some of the most common
clearances to keep in mind are shown in Figure 11.
Important: All vent clearances must be maintained.
Check your vent termination clearances against Figures 11 and 12.
The vent should be placed so that people cannot be burned
by accidentally touching the vent surfaces when the stove
is operating.
The vent termination should be located where it cannot be
damaged by such things as automobile doors, lawn mowers
or snowblowers and it should be located away from areas
where it could become blocked by snow, etc.
Some considerations are:
• Obstructions or impediments to venting.
• Nearby combustible materials that could come into contact with combustion exhaust gases.
• Other nearby openings {within 12" (305 mm)} through
which exhaust gas could reenter the building.
• All vegetation within 3’ (76 mm) that may interfere with
the draft.
Other factors that inuence where the installation will be
sited include the location of outside walls, where additional
heat may be desired in the home, where the family members gather most regularly, and perhaps most importantly,
the distance limitations of the venting system.
IMPORTANT
The horizontal termination must not be recessed into
the exterior wall or siding.
Horizontal vent runs must be level toward the vent
termination.
Clearances around the vent termination must be
maintained.
For installations using DuraVent pipe, parallel installations with minimum wall clearance have restricted
access for connecting the Horizontal Vent Cap straps
to the vent pipe. See the maker’s instructions for recommended installation procedures.
Your stove is approved to be vented either through the side
wall, or vertical through the roof.
• HHT does not require any opening for inspection of vent
pipe.
• Only HHT SLP venting components or DuraVent vent-
ing components specically approved and labeled for
this stove may be used.
• Minimum clearances between vent pipes and combustible materials is one (1") inch (25 mm), except where
stated otherwise.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes, garden
sheds, fences, decks or utility buildings within 24" from the
front of the termination hood.
Do not locate termination hood where excessive snow or
ice build up may occur. Be sure to check vent termination
area after snow falls, and clear to prevent accidental blockage of venting system. When using snow blowers, make
sure snow is not directed towards vent termination area.
LOCATION OF VENT TERMINATION
It is imperative the vent termination be located observing
the minimum clearances as shown in this manual.

VENTING SYSTEM ASSEMBLY
CAUTION
All HHT Direct Vent Stoves have been tested and
approved to ANSI/CSA Standards and will operate
safely when installed in accordance with this instruction
manual. Read all instructions before starting installation,
then follow these instructions carefully to maximize
stove performance and safety. Report damaged parts
to your dealer.
WARNING
Always maintain minimum clearances around vent
systems. Rear/Top Vent Vertical Side wall: Horizontal
sections of this vent system require a minimum of 3”
(76 mm) clearances to combustibles at the top of the
ue and 1” (25 mm) clearance at the sides and bottom
until the ue penetrates the outside wall. A minimum 1”
clearance all around the ue is acceptable at this point of
penetration. If vertical rise is 71⁄2 feet (2.3 m) or higher
when top venting, the clearance to combustibles is 1” on
all sides of the horizontal run. FOR VERTICAL RUNS
ONLY, maintain a 1” (25 mm) minimum clearance to all
sides. Do not pack the open air spaces around the stove
or ue with insulation or other materials. Any horizontal
run must have a 1/4” rise for every one (1) foot of run
towards the vent termination. Never run the vent level
or down.
• These models are approved to use HHT direct vent
pipe components and HHT termination kits, and DuraVent components. No other venting system components may be used.
• Horizontal runs must be supported every 3 feet (914
mm) using wall straps. Vertical runs must be supported
every 8 feet (2.4 m) using wall straps. Slip wall straps
loosely on to pipe. Attach straps to framing members
using nails or screws. Tighten nut/bolt to secure pipe.
• The stove and venting system should be inspected
before initial use and at least annually by a qualied
eld service person. Inspect the external vent cap on a
regular basis to make sure that no debris is interfering
with the airow. Inspect entire venting system to ensure
proper function.
Failure to follow these instructions may create a possible
re hazard and will void the warranty.
Any common venting of this gas appliance with other
gas appliances is not allowed.
Important Safety Information
The termination cap MUST be vented directly to the outside. The termination kit MUST NEVER be connected to
a chimney ue(s) servicing a separate solid-fuel burning
appliance or any other appliances.
• Termination cap MUST NOT be recessed into a wall
(see Figure 19).
• The installation must conform with local codes or in
the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1 (in the United States) or with the
current installation code CSA B149 (in Canada).

ASSEMBLY AND INSTALLATION
ASSEMBLE SLIP SECTIONS
The outer ue of the slip section should slide over the outer
ue of the pipe section and into (inner ue) the last pipe
section (see Figure 23).
Slide together to the desired length, making sure that a
11⁄2" outer ue overlap is maintained between the pipe
section and slip section.
The pipe and slip section need to be secured by driving
two 1/2 in. screws through the overlapping portions of the
outer ues using the pilot holes (see Figure 24).
This will secure the slip section to the desired length and
prevent it from separating. The slip section can then be
attached to the next pipe section.
If the slip section is too long, the inner and outer ues of
the slip section can be cut to the desired length.
WARNING
Risk of Fire/Explosion! DO NOT break seals on slip
sections. Use care when removing termination cap from
slip pipe. If slip section seals are broken during removal
of the termination cap, vent may leak.
