VENTING
Vent System Installation Precautions
Before installing vent kits, read these instructions and the Vent Kit
Instructions to ensure installation. Consult local Building Codes
before beginning the Installation.
To ensure top performance, safety and efficiency, inserts must be
installed with an approved flue liner as per CAN/CGA B-149 or
National Fuel Code ANSI Z223 and these instructions.
WARNING
This gas insert and vent assembly must be vented directly to
the outside and must never be attached to a chimney serving
a separate solid-fuel burning or gas-venting appliance.
Vent System Approvals
Figure 10
shows the vent termination cap and system approved
for use with these models. Approved vent system terminations
are labeled for identification. Use 3-inch diameter, flexible
aluminum or stainless steel gas venting for both the incoming
combustion air and exhaust vent pipes.
No other venting
systems or components may be used.
Detailed installation
instructions are included with each vent termination kit and
should be used in conjunction with this manual.
Horizontal Venting
The vent system on this model
CANNOT
be terminated
horizontally.
Vertical Venting
The inlet and exhaust vent pipes
MUST
be connected to the
proper collars on the unit
AND
to the termination cap or the unit
will not operate. The intake vent collar is identified by a stamped
“
I
”
on the top collar sliding vent plate assembly.
WARNING
Major U.S. building codes specify minimum chimney and/or
vent height above the roof top. These minimum heights are
necessary in the interest of safety. See Figures 11 and 12 for
minimum heights, provided the termination cap is at least 2
feet from a vertical wall and 2 feet below a horizontal overhang.
NOTICE:
The above warning also pertains to vertical vent
systems installed on the outside of the building.
WARNING
The exhaust pipe must only be connected to the exhaust
starting collar of the unit and to the exhaust collar of the
termination cap.
The inlet air pipe must only be connected to the inlet air
starting collar of the unit and to the inlet air collar of the
termination cap. Both the inlet vent and the flue vent must
be connected from the insert to the vent termination cap.
NOTICE
:
The minimum vertical vent rise is 10 feet and the
maximum vertical vent rise is 35 feet. These dimensions are
measured from the starting collars of the unit to the end of the
last section of vent pipe.
See Figure 10.
NOTICE
:
The damper of the masonry chimney may need to be
removed to install the flexible-vent pipe.
When installing into a zero clearance, factory built wood-burning
fireplace, the DVKI2P Round Vertical Termination Kit should allow
you to mount the vent adaptor and cap to the exposed round
chimney pipe.
NOTICE:
The vent cap must be in open, free air. It cannot be
installed under an existing cap shared by other flues.
