Venting Installation Instructions - Comfort Glow CTDV36NR-A Owner's Operation And Installation Manual

VENTING INSTALLATION
INSTRUCTIONS
NOTICE: Read these instruc-
tions completely before at-
tempting installation.
These models are tested and approved for
use with FMI PRODUCTS, LLC (direct-vent)
pipe components and terminations as well as
Simpson-Duravent direct-vent pipe compo-
nents and terminations.
The venting system must terminate on the
outside of the structure and can not be at-
tached to a chimney or flue system serving a
separate solid fuel or gas burning appliance.
A direct-vent appliance must have its own
venting system. DO NOT common vent this
appliance.
These models are approved to be vented
either horizontally through an outside wall or
vertically through a roof or chase enclosure
using the following guidelines:
• When venting system terminates horizon-
tally on an outside wall, you may install
a standoff if the termination cap is to be
installed directly on a combustible finish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which
could cause a fire.
• Vent pipe air space clearances to com-
bustibles are 1" on all sides except on the
horizontal sections, which requires 2" clear-
ance from the top of the pipe. Where the
termination cap penetrates a combustible
wall, 1" air space clearance is required.
• Snorkel terminations are required when
minimum clearance to grade cannot be
met (see Figure 16 on page 12).
• Have fireplace and selected vent compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall firestops when penetrating
walls and firestops when penetrating ceil-
ings or attic spaces.
• If using a venting configuration of only
horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.
8
tions completely and thoroughly
before attempting installation.
Failure to do so could result in
serious injury, property damage
or loss of life.
NOTICE: Failure to follow these in-
structions will void the warranty.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
INSTALLATION pRECAUTIONS
• Wear gloves and safety glasses for protection
• Use extreme caution when using ladders or when
on roof tops
• Be aware of electrical wiring locations in walls and
ceilings
The following actions will void the warranty on your
venting system:
• Installation of any damaged venting component
• Unauthorized modification of the venting system
(Do not cut or alter vent components)
• Installation of any component part not manufac-
tured or approved by FMI PRODUCTS, LLC
• Installation other than as instructed by these
instructions
and vent assembly must be vented
directly to the outside. The venting
system must NEVER be attached
to a chimney serving a separate
solid fuel burning appliance. Each
direct-vent gas appliance must
use a separate vent system. Do not
use common vent systems.
space clearances to combustibles
are 1" on all sides except on the
horizontal sections, which require
2" clearances from the top of the
pipe. Where the termination cap
penetrates a combustible wall, 1"
air space clearance is required.
