Non-combustible Facing Board

Caution: This non-combustible board can be damaged if
dropped or struck. Handle with care.
Inspect board prior to installation. Do not install if cracked.

1) Using drywall screws - secure non combustible material
around unit, framing and top nailing strip every 6 inches.

Important Note: To avoid cracking the board - pre-drill holes prior to
securing to unit/ framing.

2) Wipe any debris/dust from the non combustible
material and drywall.

3) Prior to taping and mudding it is highly recommended
to prime the facing and edges using a quality primer. This will
ensure proper adhesion of both the tape and mud.
The optional board is very porous. During dry fi t, ensue that both
surfaces being taped are even.

4) Tape the seams using a mesh type tape.

5) Mud seams as normal We recommend using a
product called Durabond high strength compound - for the fi rst coat
This product can be found at any hardware store.
Mud must be cured as per manufacturer’s recommendations.

6) Prime wall for a second time for proper adhesion of paint

7) Paint walls using a high quality paint which will withstand

the high temperatures being emitted from this appliance.

Note: Due to the high temperatures being emitted from
this appliance, incorrectly mudded joints may crack. Keep mud
thickness to a minimum.

FRAMING & FINISHING

INSTALLATION

1) Frame in the enclosure for the unit with framing material.
IMPORTANT: Header must be metal stud. All other framing may be of

combustible type such as 2x4 / 2x6 framing materials.

ote: When constructing the framed opening, please ensure there is ac-

cess to install the gas lines when the unit is installed.

2) For exterior walls, insulate the enclosure to the same degree as the rest

of the house, apply vapour barrier and drywall, as per local installation
codes. (Do not insulate the fi replace itself.)

WARNING: Failure to insulate and add vapor barriers to the inside of

the exterior wall will result in operational and performance problems
including, but not limited to: excessive condensation on glass doors,
poor fl ame package, carbon, blue fl ames etc. These are not product
related issues.

3) The unit does not have to be completely enclosed in a chase. You must

maintain clearances from the vent to combustible materials: See "Clear­ances" section. Combustible materials can be laid against the side and
back standoffs and the stove base.

4) The combined total of non-combustible facing materials (ie. hardiboard
+ tile, slate, etc) may be brought up to and overlap the face of the unit
(top and bottom). The minimum thickness = 1/2"

to a maximum thickness = 1-1/2", as shown in the diagram below.
If material is thicker than 1-1/2" - it will not be possible to mount

the faceplace.

5) When fi nishing around the faceplate, if material such as brick, stone, etc.

extend past the faceplate depth - the minimum opening

dimensions noted below must be adhered to, this is to ensure removal

of the faceplate.

6) Determine the total thickness of facing material (eg. hardiboard + ceramic
tile) to ensure the fi nished surface is fl ush with the front edge of the
unit (see diagram below). If necessary, side and top nailing strips are
adjustable, loosen the 1/4" screws and adjust.

Total non-combustible facing allowable: Min. = 1/2"
Max. = 1- 1/2"
See diagram below.

* Framing depth measurement is noted with the side nailing strips set as far forward on the fi rebox as possible.

The side nailing strips can be adjusted back up to 1” to allow for varying thicknesses in non-combustible material
& wall fi nishes.
Important: The minimum framing dimensions given for height, width and depth must be maintained even if using
non combustible materials.
Dangerous operating conditions will occur if minimum framing dimensions are not adhered to.

INSTALLATION

UNIT ASSEMBLY

PRIOR TO

INSTALLATION

The Top Standoff/ Nailing Strip, side nailing strips and standoffs must be
correctly positioned and attached to the unit before sliding the unit into position.

STANDOFF ASSEMBLY

The top, side, rear and bottom standoffs are shipped in a fl at position and
must be folded into shape and attached - see diagram 1.

1) Remove the standoffs from the unit.

2) Take each standoff and bend into the correct shape. Bend up at the bend

lines until the screw holes in the standoff and the pre-punched screw holes
on the unit line up.

Diagram 1

The top stand off / nailing strip is shipped attached to the back of the unit as
shown below.

NAILING STRIPS

The nailing strips come attached to the unit. There is 1 plate on each side,1
on the top, and one on the bottom that can be folded out as required. The
top and side nailing strips are secured to the framing. The bottom nailing
strip is secured to the unfi nished fl oor - if installing the unit directly on the
fl oor.

Note: The bottom nailing strip will need to be bent on site and
adjusted to accommodate the thickness of the facing material.

Standoff

Standoff

1) Remove one screw in location shown below.
Replace the screw on the back the unit after removing the
standoff / nailing strip.

2) Bend the 3 tabs at the bottom of the stand off / nailing strip to 90°,
bend in the same direction as the top tabs.

3) Install on the top front of the unit as shown in diagram 3. Do not fully
tighten the screws when installing - until the facing thickness has been
determined.

IMPORTANT NOTE

Framing depth measurement is noted with

be adjusted back up to 1” to allow for varying
thicknesses in non-combustible material & wall
fi nishes.

VENTING INTRODUCTION

The HZ54EPV uses the "balanced fl ue" technology Co Axial system. The
inner liner vents products of combustion to the outside while the outer liner
draws outside combustion air into the combustion chamber thereby eliminating
the need to use heated room air for combustion and losing warm room air
up the chimney.

Note: These fl ue pipes must not be connected to any other appliance.

The gas appliance and vent system must be vented directly to the outside of
the building, and never be attached to a chimney serving a separate solid fuel
or gas burning appliance. Each direct vent gas appliance must use it's own
separate vent system. Common vent systems are prohibited.

VENT RESTRICTOR POSITION

Vent restriction is required for certain venting installations, see the diagrams in the "Venting
Arrangements" section to determine if they are required for your installation.

The Vent Restrictor plate is located on the inside top of the fi rebox.
To set the vent restriction as indicated in the venting arrangements diagrams, refer to the following instructions;

1) Remove the glass door.

2) Remove the screws that hold the vent restrictor plate in place.

3) Adjust the vent restrictor plate to the required vent restrictor position as per the diagrams shown.

4) Once the vent restrictor plate is in the required position, secure with screws.
