etc. is desired directly above the
replace. The outlet of the HDK can be
raised higher up the front wall, within
4” of the room’s ceiling, or ducted into a
different room for a cleaner front wall.
Note: Dual Convection Fan Kit
(50-3212) may not be used in
conjunction with HDK.
Prior to installation of the HDK make
sure the desired location is large
enough to comply with the combustible
clearances of both the HDK and the
replace (see Owner’s Manual for
replace installation instructions). Refer
to the Framing and ClearanCes section of
this manual for the required installation
dimensions of the HDK.
Please refer to Figure 1 to ensure that all
HDK parts are accounted for and have
not been damaged.

The HDK may also be installed to
discharge into another room for a
cleaner installation on the replace
side of the wall (see Figure 6). As
stated in the previous section, the
vent pipe can be ran straight up
through the cut out in the HDK.
The minimum clearances stated in
Figure 6 must be maintained as well
as the minimum distance between
the replace and the HDK (see
gures 3 & 4).
minimum ClearanCes - vertiCal vent:
The HDK has been designed to allow for installations where a vertical run of vent is required without
having to jog the vent pipe around the HDK (see Figure 6). The horizontal vent shield supplied with the
replace is not required (see Owner’s Manual) when vertically venting and the vent pipe can simply be
run straight up through the cut out in the HDK.
minimum ClearanCes - adjoining room:
Warning: HDK MUST NOT
discharge outdoors or into a
garage. HDK is only approved for
horizontal installation and MUST
NOT be installed in a oor or
ceiling.
Figure 6. HDK - Adjoining Room
When installing the HDK in an
adjoining room the 5” dia. ex
venting cannot exceed a vertical run
of 12’ (3.65 m). The ex venting
also cannot exceed a horizontal run
in excess of 8” (2.5 cm) for every
12” (30.5 cm) of vertical rise, up to
a maximum of 8’ (2.4 m).

Combustible wall material i.e. drywall, shiplap etc. is permitted around the outlet of the HDK with
a 3/8” (.95 cm) air gap required around the outside perimeter of the outlet. This creates a nished
opening approx. 40¾” x 2⅞” (103.5 x 7.3 cm) in size (Figure 7).
The supplied Outlet Trim Bezel, once installed, covers the air gap for a clean nished install (Figure
8). The Trim Bezel can be adjusted to accommodate nished walls ½”-1” (1.3-2.5 cm) thick and be
painted to match the colour of the wall if desired (must be hi-temperature rated).

Installation
tv installation Considerations:
If you are planning to mount a TV above your replace some considerations must be made to ensure it
is protected from the heat.
During testing temperatures did not exceed 120°F (49°C) midway up the front wall (Figure 9).
There is no guarantee that these temperatures will not harm the longevity of your TV. Make sure to
consult your TV manufacturer’s specications to nd the maximum allowable operating temperature.
Since every home and installation is unique, temperatures should be veried at the time of install if
possible. If desired, front wall temperatures can be lowered further with the use of a mantle (Figure 10).
Refer to Owner’s Manual for full mantle clearances. A TV should not be installed if temperatures exceed
the manufacturers maximum allowable temperature.
Installation and service must be performed by a qualied installer,
service agency or the gas supplier.

Installation
QUALIFIED INSTALLERS ONLY
hi-limit switCh: (For use with ipi FireplaCes only)
Supplied with the HDK is a Hi-Limit switch assembly that must be installed if the HDK is being used on
an IPI equipped replace. Installation of the Hi-Limit switch is easy and only takes a couple minutes.
Step 1: Prior to installation of the replace, remove
the safety screen assembly. Next, remove the front
cover using a T20 screwdriver (see Figure 11).
Step 2: Using a T20 screwdriver, loosen the left
mounting screw of the IFC and slide the Hi-Limit
Switch Bracket onto the IFC as shown. Next, retighten
the left mounting screw (see Figure 12).
Note: Placement of the Hi-Limit switch is not arbitrary
and must be correct for proper operation. When
correctly installed, the bracket should contact both the
mount ange and left side of the IFC (Figure 12).
Step 3: Using a small at-blade screwdriver, loosen
the terminals on the IFC ON/OFF plug (X4 on IFC)
and remove the jumper wire (see Figure 13). Next,
insert the wires from the Hi-Limit Switch and re-
tighten the terminals. There is no polarity to the
wires so they cannot be wired backwards.
Step 4: The Hi-Limit Switch installation is now complete. The front cover and safety screen may now
be re-installed on the replace.
Note: In rare circumstances, when the HDK is installed in an adjoining room, a large difference in
room pressure may temporarily cause the HDK to reverse ow. If this occurs over a prolonged period
of time the Hi-Limit Switch will automatically turn off the replace to protect the IFC. Once the replace
has cooled sufciently (approx. 10-15 minutes) it will automatically re-start and continue normal
operation.

duCt Collars:
Prior to replace installation, the two supplied duct collars
must be attached to the top of the replace as shown in
the steps below:
Step 1: Using a T20 screwdriver, remove the inner and
outer cover plates from the replace as shown (Figure
14). Each cover plate has four (4) mounting screws.
Both sets of cover plates are no longer required and can
be recycled. Retain eight (8) of the removed mounting
screws to secure the duct collars.

heat distribution Kit:
Step 1: Frame in the rough opening for the HDK as shown in Figures 3 & 4 (Pages 3,4) in the desired
location following all required clearances as stated in the Framing & ClearanCes section.
Note: Light coloured ceilings may slightly discolour near the outlet when it is installed at
minimum clearance (4” / 10.2 cm). Increasing the ceiling clearance will help prevent this.
Step 2: Using a T20 screwdriver, remove the screw on each side
of the HDK outlet retaining the Outlet Trim Bezel and remove the
Bezel (Figure 17).
Step 3: Insert the assembled HDK into the framed rough opening
by rotating it down slightly to allow the outlet and standoffs to
pass through. When installed correctly the front ange of the
top standoff should be up against the front face of the top stud
(Figure 3 & 18).
Step 4: Conrm the HDK is centered within the rough opening
and secure in place using screws or nails through the four (4)
holes along the top edge of the top standoff.
Figure 17. Outlet Trim Bezel Screw
Step 5: Secure the rear standoffs to support the remainder of
the HDK ensuring it is level. If left unlevel, the outlet of the HDK
will be out of square causing possible tment issues with the
Outlet Trim Bezel.
Step 6: Install the replace in the desired location as directed in
the Owner’s Manual. Leave the front wall open for installation of
the ex venting.
Note: Flex venting must be non-insulated and listed to
UL 1777 and ULC S635 standards
Step 7: Connect the required lengths of 5” dia. stainless steel
or aluminium ex vent (not supplied) between the collars on the
replace and HDK. Secure the venting to the collars using either
Figure 18. HDK - Top Standoff
sheet metal screws or band clamps. Both collars on the HDK must be connected to the replace
via 5” dia. ex vent. Secure the ex venting where necessary to maintain standard venting
