INSTALLATION
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
The Standoffs and Nailing Strips must be correctly positioned and attached
to the fi rebox before unit is slid into position.
ST ANDOFF ASSEMBLY
The side, top and rear standoffs are shipped in a fl at position and must
be folded into shape and attached.
1) Remove the standoffs from the fi replace.
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 fi replace side line up.
3) Attach the standoff securely to the side with 2 screws per standoff (on
opposite corners).
NAILING STRIPS
The side, top and bottom nailing strips come attached to the unit. There
are 3 plates on each side and 2 on the bottom - 8 in total. They can be
folded out as required. The bottom nailing strip is secured to the unfi nished
fl oor - if installing the unit directly on the fl oor.
Nailing Strips
Nailing Strips shown folded out.
Standoff
IMPORTANT NOTE
Framing depth measurement is noted with the
side & top nailing strips set as far forward on
the fi rebox as possible. The nailing strips can
be adjusted back up to 1” to allow for varying
thicknesses in non-combustible material & wall
fi nishes.
INSTALLATION
HORIZONTAL VENT DEFLECTOR INSTALLATION
Note: This installation is only required for horizontal terminations.
If any rise is used when venting this unit - the defl ector and
extender are not required.
1) The defl ector and extender are shipped on top of the fi rebox.
Slide the defl ector out from under the nailing strip and lift the
extender up off the nailing strip.
Defl ector
Defl ector extender
2) Remove the 3 screws near the vent outlet on the fi rebox - as shown
below.
3) Install the defl ector near the vent outlet - secure with the same
3 screws. Ensure fl ange on defl ector is facing downward.
4) Install the extender on top of the defl ector with 2 screws -
slide the extender until it touches the outside wall - tighten
screws to secure. Extender can be adjusted to max. 15-1/2".

INSTALLATION
FRAMING & FINISHING
1) Frame in the enclosure for the unit with framing material.
IMPORTANT: Vertical studs and the header must be metal.
Note: When constructing the framed opening, please ensure there
is access to install the gas lines when the unit is installed.
2) The unit does not have to be completely enclosed in a chase. You
INSTALLATION
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.
3) Non-combustible material (ie. tile, slate, etc) may be brought up to and
overlap the unit (top and bottom) ensuring that the maximum thickness does not go beyond the 1-1/2" as shown in the diagram below.
The faceplate will not be able to be mounted if the fi nished material
is beyond 1-1/2".
4) If material such as brick, stone, etc. extends past the faceplate depth,
when fi nishing around the faceplate, the minimum opening dimen-
sions noted below must be adhered to ensuring for the removal of the
faceplate and for the safe operation of this appliance.
