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 C44
replace (see C44 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 5). 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 5 must be maintained as well
as the minimum distance between
the replace and the HDK (see
gure 3).
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 5). The horizontal vent shield supplied with the
C44 is not required (see C44 Owner’s Manual) when vertically venting and the vent pipe can simply be
run straight up through the cut out in the HDK.
Note: When supporting the rear of the HDK, standard venting clearances must be maintained (see C44
Owner’s Manual)
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 5. 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 6).
The supplied Outlet Trim Bezel, once installed, covers the air gap for a clean nished install (Figure
7). 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).

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. There is no
guarantee that these temperatures will not harm the longevity of your TV. Make sure to consult your TV
manufacturer’s specications to nd the maximum allowable operating temperature. Since every home
and installation is unique, temperatures should be veried at the time of install if possible. If desired,
front wall temperatures can be lowered further with the use of a mantle (see C44 Owner’s Manual). A
TV should not be installed if temperatures exceed the manufacturers maximum allowable temperature.
Installation and service must be performed by a qualied 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 C44 replace. Installation of the Hi-Limit switch is easy and only takes a couple minutes.
Step 1: Prior to installation of the C44, remove the
safety screen assembly. Next, remove the front cover
using a T20 screwdriver (see Figure 8).
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 9).
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 9).
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 10). 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 C44.
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 C44 to protect the IFC. Once the C44 has cooled
sufciently (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 C44 as shown in the
steps below:
Step 1: Using a T20 screwdriver, remove the inner and
outer cover plates from the C44 as shown (Figure 11).
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.

Step 2: Attach the supplied duct collars to the
top of the C44 cabinet as shown (Figure 12).
Secure the collars by re-using the eight (8)
screws saved in the previous step.
The C44 is now HDK ready!

rear standoFFs:
Prior to installation of the HDK the
supplied set of rear standoffs need to
be attached to the back of the main
duct body.
Using a T20 screwdriver and the
supplied screws, attach the rear
standoffs with the anges pointing
down as shown in Figure 13.

heat distribution Kit:
Step 1: Frame in the rough opening for the HDK as shown in Figure 3 (Page 3) 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 14).
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 & 15).
Step 4: Conrm 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 14. 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 C44 replace in the desired location as
directed in the Owner’s Manual. Leave the front wall open for
installation of the ex venting.
Step 7: Connect the required lengths of approved 5” dia.
stainless steel or aluminium ex vent (not supplied) between the
collars on the C44 and HDK. Secure the venting to the collars
using either sheet metal screws or band clamps. Both collars
on the HDK must be connected to the C44 via 5” dia.
ex vent. Secure the ex venting where necessary to maintain
standard venting clearances (see C44 Owner’s Manual).

Step 8: Finish the front wall around the replace and HDK outlet as desired. Ensure the nished
opening around the HDK outlet is as specied in the Finished Opening section of this manual.

Step 9: Finally, install the Outlet Trim Bezel
by sliding it into the outlet until the backside
contacts the nished wall surface. Next, re-
install the two (2) screws removed in Step
2 to secure the Outlet Trim Bezel in place.
When installed correctly there is a ¼” (6.4
mm) standoff between the back side of the
Bezel and nished wall (Figure 16).
