MANTEL LEG CLEARANCES
Combustible mantel leg clearances as per diagram below:
MANTELS
Because of the extreme heat this fireplace emits, the mantel clearances are critical.
Combustible mantel clearances from louver are shown in the diagram below.
Note: A non-combustible mantel may be installed at a lower height if the framing is made
of metal studs covered with a non-combustible board.
INSTALLATION
This drawing is to scale at 1:6 (one inch = 6 inches)
Mantel can be installed anywhere in shaded area using the above scale for units with the Flush
Front and with the optional Bay Front.
Note: Ensure the paint that is used on the mantel and the facing is "heat resistant" or the
paint may discolour.
Maximum
1-1/2" projection at 2"
minimum clearance.
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
ventsystembe installed onlyinaccordance
with these instructions.

5) The unit does not have to be completely
enclosed in a chase. The clearance on top
of the unit from the top standoffs is 0" so
combustible building materials can be laid
directly on top of the standoffs. You must
maintain these clearances from the vent
to combustible materials: Flex Termination

clearance or (1-1/4" (32mm). Combustible
materials can be laid against the side and
back standoffs and the fireplace base.
b) Mountthe Side Nailing Stripusingthe 3
supplied screws into the 3 screw holes
or slots (diagram 4) on the side of the
unit and repeat for the other side. Use
the hole for a 1/2" (13mm) thick facing
material and the slot for a range of
thickness from 3/4" to 1-1/2" (25mm to
38mm).
VENTING
INTRODUCTION
The P42 uses the "balanced flue" technology
Co-Axialsystem.Theinnerlinerventsproducts
of combustion to the outside while the outer
liner draws outside combustion air into the
combustion chamber thereby eliminating the
needtouseheatedroomairforcombustionand
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.
Eachdirectventgasappliancemustuseit'sown
separate vent system. Common vent systems
are prohibited.
VENT RESTRICTOR
A vent restrictor may be required. Check
the diagrams in the "Rigid Pipe Venting
Arrangements" section to determine if the #6
restrictor is needed for your vent configuration.
If required, attach the 2 piece #6 restrictor

FRAMING AND
FINISHING
1) Determine the total thickness of facing
material (ie. drywall plus ceramic tiles) to
allow the finished surface to be flush with
the front of the unit. Total facing thickness
canvaryfrom1/2"(13mm)to1-1/4"(32mm)
thick.
2) Frame in the enclosure for the unit with
framing material. The framed opening for
the assembled kit is 36-5/8" high x 40-1/4"
wide x 19" deep (930mm H x 1022mm W
x 483mm D). See Diagram 1.
3) Forexteriorwalls,insulatetheenclosureto
the same degree as the rest of the house,
apply vapour barrier and drywall, as per
local installation codes. (Do not insulate
the fireplace itself.)
4) The top louvers must not be closer than
36" (914mm) to the ceiling.
The HeatWave Duct Kit has different
clearance and framing requirements,
check the HeatWave manual for details.

RIGID PIPE VENTING
Horizontal or Vertical Terminations
The Rigid Pipe Venting System offers a complete line of component parts for installation of both horizontal and vertical installations. Many items are
offered in decorative black, as well as galvanized finish. We recommend using the galvanized finish for installation with the P42.
The minimum components required for a basic
horizontal termination are:
1 Horizontal Termination Cap
1 90oElbow
1 Flue Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness

Wall thickness is measured from the back
standoffs to the inside mounting surface of
termination cap. For siding other than vinyl
furring strips may be used, instead of the vinyl
siding standoff, to create a level surface to
mount the vent terminal. The Terminal must
not be recessed into siding. Measure the wall
thickness including furring strips.
If a Vinyl Siding Standoff is required (it must
be used with vinyl siding), measure to outside
surface of wall without siding and add 2
inches.
When using Rigid Vent other than
Simpson Dura-Vent, 3 screws must be
used to secure rigid pipe to adaptor.
