Vent Termination Clearances - Vermont Castings RADVTCB Homeowner's Installation And Operating Manual

Radiance ® Direct Vent Gas Heater
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 11.
Important: All vent clearances must be maintained.
Check your vent termination clearances against Fig-
ures 11 through 13.
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 1" (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 mem-
bers gather most regularly, and perhaps most importantly,
the distance limitations of the venting system.
• 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 proce-
dures.

Vent Termination Clearances

IMPORTANT
Your stove is approved to be vented either through the side
wall, or vertical through the roof.
•
Vermont Castings Group does not require any open-
ing for inspection of vent pipe.
•
Only Vermont Castings Group, DuraVent and Sel-
kirk Corporation venting components specifically
approved and labelled for this stove may be used.
•
Minimum clearances between vent pipes and com-
bustible 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 4" 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 on this page.
