VENTING INSTALLATION INFORMATION
WARNING
Read all instructions completely and thoroughly before
attempting installation. Failure to do so could result in
serious injury, property damage or loss of life. Operation
of improperly installed and maintained venting system
could result in serious injury, property damage or loss
of life.
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 venting
system:
•
Installation of any damaged venting component.
•
Unauthorized modification of the venting system.
•
Installation of any component part not manufactured
or approved by Vermont Castings Group.
•
Installation other than permitted by these instruc-
tions.
WARNING
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
units only), the clearances for the horizontal run is 1"
at the top.

GENERAL VENTING
Your fireplace is approved to be vented either through the
side wall, or vertical through the roof.
•
Only Vermont Castings Group venting components
specifically approved and labelled for this fireplace
may be used.
•
Flexible UL1777 listed venting may be used in any vent-
ing application where rigid direct vent components can be
used. All restrictions, clearances and allowances that per-
tain 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 adapters. This may
occur only if doing so does not violate any of the venting
length, height, routing, horizontal to vertical raito require-
ments or clearance considerations detailed in this manual.
•
Venting terminals shall not be recessed into a wall or siding.
•
Select the amount of vertical rise desired. All horizontal run
of venting must have 1/4" rise for every 12" of run towards
the termination below 7
feet or more vertical rise off top of fireplace, the horizontal
run may run level. NEVER run vent piping downward.
•
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
•
Horizontal venting which incorporates the use of flex vent-
ing 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 termination
area after snow falls, and clear to prevent accidental block-
age 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.
WARNING
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.
Failure to follow these instructions will void the
warranty.
