and may present a fire hazard.

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 labeled 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
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 adapters. This
may occur only if doing so does not violate any of the
venting length, height, routing, horizontal to vertical ratio
requirements or clearance considerations detailed in this
manual.
•
Venting terminals shall not be recessed into a wall or sid-
ing.
•
Vertical side wall venting in horizontal applications must
be installed with a 1/4" rise for every 12" of run.
•
Select the amount of vertical rise desired. All horizontal
run of venting must be run level or have 1/4" rise for every
12" (305 mm) of run towards the termination below 7
feet of vertical rise. With 7
rise from floor of fireplace, the horizontal run may run lev-
el. NEVER run vent piping downward.
•
Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of 1/2"
(13 mm) per 12" (305 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.
