P40 Direct Vent Gas Fireplace

INSTALLATION
VENTING
INTRODUCTION
The P40 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 flue 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.
* For "C" screw position the top facing support
is reversed.
Note: For screw position C with a facing
material depth of 1-1/4" (32mm), the top
facing support must be reversed.
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
NOTE: The Top Facing Support, the Side Nailing
Strips and the 2 Top Standoffs must be correctly
positioned and attached before unit is slipped
into position.
TOP STANDOFF ASSEMBLY
The top standoffs are shipped in a fl at position
and must be folded into shape and attached.
1) Remove the standoffs from top of 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 top
line up.
3) Attach the standoff securely to the top
with 2 screws per standoff (on opposite
corners).
TOP FACING SUPPORT AND
SIDE NAILING STRIPS
Determine the total thickness of facing material
to allow the fi nished surface to be fl ush with the
front of the unit. Total facing thickness can vary
from 1/2" (13mm) to 1-1/4" (32mm) thick.
The Top Facing Support & Side Nailing Strips can
be mounted in 3 different positions depending
on the thickness of the facing material.
1) Mount Top Facing Support using the 3
supplied screws into the three pre-punched
screw holes on the top front of the unit. Use
hole positions A, B, or C depending on your
facing depth.
2) Use the same screw hole position for the
Side Nailing Strips as was used for the Top
Facing Support. Attach each side nailing
strip using 3 screws.

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.
To set the Vent restriction as indicated in the
diagrams in the "Venting Arrangements" section,
refer to the instructions below;
1) Remove the top louver if installed.
2) Loosen the screw on the vent restrictor
indicating plate.
3) Rotate the vent restrictor adjustment rod
counter clockwise to line up the slot on the
indicating plate with the point on the air box
to the required setting.
4) Tighten screw to lock position.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.
Note: When installing side strips into
position C, the side strips are not reserved.
