VENTING AND INSTALLATION
Vent System Approvals
Figure 8
shows the vent termination caps and systems approved
for use with these models. Approved vent system terminations are
labeled for identification. 3-inch diameter listed flexible aluminum
or stainless steel gas vent is used 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 8 THROUGH 10 FOR
MINIMUM HEIGHTS, PROVIDED THE TERMINATION CAP IS
AT LEAST 2-FEET FROM A VERTICAL WALL AND 2-FEET
BELOW A HORIZONTAL OVERHANG.
Note:
This 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 8.
NOTICE
:
The damper of the masonry chimney may need to be
removed to allow installation of the flexible-vent pipe.
When installing into a zero clearance, factory built wood-burning
fireplace, the use of the DVKI Round Vertical Termination Kit should
allow you to mount the vent adaptor and cap to the exposed round
chimney pipe easily.
Connecting the Vent Pipe
CAUTION
Sharp edges. Always use gloves when installing.
Install the 3-inch flexible vent pipes down through the chimney.
Attach the pipe-to-cap adaptor to the termination cap and the top of
the flexible vent pipe, then install the cap to the top of the chimney.
Remove the vent slide plate assembly from the top of the insert.
See Figure 7.
Trim off excess venting then attach and secure
the bottom ends of the flex pipes to the starting collars with the
adjustable band clamps provided. Slide the gas insert into place,
and position any excess flex vent pipe back up into the chimney.
Begin installation of the insert into the fireplace opening. Align
the vent slide plate assembly with the guides located on top of
the insert. Work the insert inch by inch into the fireplace cavity
as you pull forward on the vent slide plate assembly. Do not use
excessive force on the vent slide plate. Once the vent slide plate is
close to seating, install the black button head 5/16-18 x 2 1/2” long
bolt through the center hole of the insert top flange, and into the
vent slide plate nut. Using the hex key wrench provided, tighten
the bolt until the vent slide plate is seated forward completely.
Positioning, Leveling, and Securing Insert
1. Place the insert into position.
NOTICE
:
The front flanges of the insert (without surround panels)
should be set at approximately 1”(inch) in front of the face of the
fireplace.
2. Level the insert from side to side and front to back.
3. If necessary, use the leveling bolts included in the instruction
pack. Screw the legs into the nuts installed in the bottom of
the insert. Turn legs in until insert is level.
Note: If desired, it is acceptable to attach metal strapping or
brackets (not provided) from the fireplace cavity to the insert
outer jacket to secure the Fireplace Insert to the fireplace
hearth or opening.
CAUTION
TO AVOID DOWNDRAFTS AND/OR COLD AIR PROBLEMS,
IT IS RECOMMENDED TO SEAL OFF THE AREA BETWEEN
THE TERMINATION CAP AND THE TOP OF THE SOLID-
FUEL CHIMNEY OPENING INTO WHICH THE VENT CAP
HAS BEEN INSTALLED.
