Your fireplace is approved to be vented either through the
side wall, or vertical through the roof.
•
only MhSC venting components specifically ap-
proved 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”
(5 mm) per 4” (610 mm).
There must not be any obstruction such as bushes, gar-
den sheds, fences, decks or utility buildings within 4”
(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.
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

feet or higher (top vent units only), the clearances for the
horizontal run is 1" at the top.
