DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)
DVFH34, DVFH34P
INSTALLATION FOR
HORIZONTAL TERMINATION
1. Determine the route your horizontal
venting will take.
Note: The location
of the horizontal vent termination on the
exterior wall must meet all local and
national building codes and must not be
easily blocked or obstructed.
Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
9 and 10). Follow the same installation
procedures as used for standard horizon-
tal terminations. If installing the snor-
kel termination below grade (basement
applications), you must provide proper
drainage to prevent water from entering
the snorkel termination (see Figure 10).
Do not back fill around the snorkel ter-
mination.
2. Rigid vent pipes and fittings have spe-
cial twist-lock connections. Assemble
the desired combination of pipe and el-
bows to the appliance adaptor with pipe
seams oriented towards the wall or floor.
Twist-lock Procedure: The female
ends of the pipes and fittings have four
locking lugs (indentations). These lugs
will slide straight into matching slots on
the male ends of adjacent pipes and fit-
tings. (All connections must be sealed
with high temperature silicone sealant
as specified in the second warning state-
ment on page 7.) Push the pipe sections
together and twist one section clockwise
approximately one-quarter turn until the
sections are fully locked. See Figure 11,
page 9.
Note: Horizontal runs of vent
must be supported every three feet. Use
wall straps for this purpose.
