MDVFST DIRECT-VENT GAS FIREPLACE
®
FRAMING
Once the final location has been determined,
observing height clearances for vent termi-
nation, you may construct framing using
dimensions shown in Figure 6, depending
on your installation.
If the appliance is to be installed directly on
carpeting, tile (other than ceramic), or any
combustible material other than wood floor-
ing, the appliance must be installed on a
metal or wood panel extending the full width
and depth of the appliance. There are three
holes on each side of the bottom of the unit
where screws can be used to secure the unit
to the floor.

Note:
Terminations are not designed for
installation prior to transportation.
These models are approved for use with both
flex and rigid Vanguard vent components as
well as Simpson Dura-Vent 6
5
/8" direct-vent
pipe components and terminations.
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.
• Install horizontal venting with a 1/4" rise for
every 12" of run toward the termination.
• You may paint the vent terminal with
450°F (232°C) 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.
