VENTING INSTALLATION
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. Before installing vent
kit, the installer must read this fireplace manual and vent
kit instructions.
Only a qualified installer/service person should install vent-
ing system. The installer must follow these safety rules:
•
Wear gloves and safety glasses for protection.
•
Use extreme caution when using ladders or when on
rooftops.
•
Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your vent-
ing system:
•
Installation of any damaged venting component.
•
Unauthorized modification of the venting system.
•
Installation of any component part not manufactured
or approved by MHS.
•
Installation other than permitted by these instruc-
tions.
Always maintain minimum clearances around
vent systems. The minimum clearances to
combustibles for horizontal vent pipe are 3"
at the top* and 1" at the sides and bottom
of the vent system until the pipe penetrates
the nearest vertical wall (1" required). A 1"
minimum clearance all around the pipe must
be maintained at outside wall and on vertical
runs. Do not pack the open air spaces with
insulation or other materials. This could
cause high temperatures and may present
a fire hazard.
* Unless the vertical run is 7
1/2
feet or higher
(top vent units only), the clearances for the
horizontal run is 1" at the top.
W
ARNING
This fireplace must be vented to the
outside. The venting system must NEVER
be attached to a chimney serving a separate
solid fuel burning appliance. Each gas
appliance must use a separate vent system.
Do not use common vent systems.

life.
GENERAL VENTING
Your fireplace is approved to be vented either through the
side wall, or vertical through the roof.
•
Only Vermont Castings Group venting compo-
nents specifically approved and labelled for this
fireplace may be used.
•
Flexible UL1777 listed venting may be used in any
venting application where rigid direct vent components
can be used. All restrictions, clearances and allowanc-
es that pertain to the rigid piping apply to the flexible
venting.
Flex kits may not be modified. Flex kits may be added
to the end of a vent run made of rigid vent sections
using pipe manufacturer's approved flex to pipe adapt-
ers. This may occur only if doing so does not violate
any of the venting length, height, routing, horizontal to
vertical raito requirements or clearance considerations
detailed in this manual.
•
Venting terminals shall not be recessed into a wall or
siding.
•
Horizontal venting which incorporates the twist lock
pipe must be installed on a level plane without an in-
clining or declining slope.
•
Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of 1”
(25 mm) per 24” (610 mm).
There must not be any obstruction such as bushes, gar-
den sheds, fences, decks or utility buildings within 24”
(610 mm) 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 termina-
tion 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 following page.
For models purchased after 4/16/15, please see addendum.
