Vent Termination Clearances
When planning the installation, consider the location of the
vent terminal and clearances. Some of the most common
clearances to keep in mind are shown in Figure 2.11.
Important: All vent clearances must be maintained.
Check your vent termination clearances against Figures
2.11 and 2.12.
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 influence 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 venting
components specifically approved and labeled for this
stove may be used.
• Maintain minimum clearances between vent pipes and
combustible materials.
• Venting terminals shall not be recessed into a wall or
siding.
• 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.
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.
