GENERAL VENTING

These models are approved for use with
5
Simpson Dura-Vent 6 / " direct-vent pipe
8
components and terminations as well as both
flex and rigid Vanguard vent components.
Your fireplace is approved to be vented either
through the side wall, or vertically using the
following guidelines:
• Only use Vanguard or Simpson Dura-
Vent GS venting components or kits spe-
cifically approved for this fireplace.
• Minimum clearance between vent pipes
and combustible materials is 1" (25 mm),
except where stated otherwise.
• Combustible material may be flush with
the top front of fireplace with a maxi-
mum thickness of 3/4".
• Do not recess venting terminals into a
wall or siding.
• You must install a vinyl siding standoff if
vinyl siding is covering the exterior wall.
• Install horizontal venting with a 1/4" rise for
every 12" of run toward the termination.
• You may paint the vent terminal with
450ºF (232ºC) heat-resistant paint to co-
ordinate with the exterior finish.
• There must not be any obstruction such
as bushes, garden sheds, fences, decks,
or utility buildings within 24" from the
front of the termination cap.
• Do not locate termination cap where exces-
sive snow or ice build up may occur. Be sure
to clear vent termination area after snow falls
to prevent accidental blockage of venting
system. When using snow blowers, do not
direct snow towards vent termination area.
LOCATION OF VENT
TERMINATION
When locating vent termination, it is impor-
tant to observe the minimum clearances
shown in Figure 8, page 6. You will avoid
extra framing by positioning your fireplace
against an already existing framing mem-
ber. The sides of the fireplace may be posi-
tioned directly against combustible walls.
*Check with local codes or with the current
CAN/CGA B149[.1 or .2] Installation Codes
for Canada or the USA Installations follow
the current National Fuel Gas Code, ANS
Z223.1, also known as NFPA 54.
