The purpose of this optional Heat Distribution Kit, or HDK, is to naturally re-direct the convective heat from

the replace. Using this HDK lowers the temperatures of the front wall for installations where a TV, artwork

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).

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. 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 (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 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 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

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 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: 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 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).

Figure 15. HDK - Top Standoff

Step 8: Finish the front wall around the replace and HDK outlet as desired. Ensure the nished

opening around the HDK outlet is as specied 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).
