if these clearances (air space) to combustible materials are not
adhered to. It is of greatest importance that this fireplace and vent
system be installed only in accordance with these instructions.
CLEARANCES
The clearances listed below are Minimum distances unless otherwise stated:
A major cause of chimney related fires is failure to maintain required clearances (air space) to combustible materials. It is of the greatest
importance that this fireplace and vent system be installed only in accordance with these instructions.

Note: When constructing the framed opening, please ensure there
is access 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 instal-
lation codes. (Do not insulate the fireplace itself.)
WARNING:Failuretoinsulateandaddvaporbarrierstotheinside
of the exterior wall will result in operational and performance
problems including, but not limited to: excessive condensation
on glass doors, poor flame package, carbon, blue flames etc.
These are not product related issues.
3) The unit does not have to be completely enclosed in a chase. You
mustmaintainclearancesfromtheventtocombustiblematerials:See
"Clearances" section. Combustible materials can be laid against the
side and back standoffs and the stove base.
4) If material such as brick, stone, etc extends past the faceplate depth,
when finishing around the faceplate, the minimum opening dimen-
sions noted below must be adhered to ensuring for the removal of the
faceplate.
FRAMING & FINISHING
1) Frame in the enclosure for the unit with framing material.
IMPORTANT: Header must be metal stud. Allother framing may be
of combustible type such as 2x4 (0.6m x 1.2m) / 2x6 (0.6m x 1.8m)

VENTING INTRODUCTION
The Gem54™ uses the "balanced flue" technology CoAxial 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 flue pipes must not be connected to any other
appliance.
Thegasapplianceandventsystemmustbeventeddirectlytotheoutside
ofthebuilding,andneverbeattachedtoachimneyservingaseparatesolid
fuel or gas burning appliance. Each direct vent gas appliance must use
it's own separate vent system. Common vent systems are prohibited.
IMPORTANT NOTE
Framing depth measurement is noted with the
nailing strips set as far forward on the firebox
(top and sides) as possible. The nailing strips
can be adjusted back - up to 1”(25mm) to
allow for varying thicknesses in
non-combustible material & wall finishes.
