3) For exterior walls, insulate the enclosure to
the same degree as the rest of the house,
apply vapour barrier and drywall, as per lo-
cal installation codes. (Do not insulate the
fireplace itself.)
4) The top of the unit must not be closer than
30" (762mm) to the ceiling.
5) Combustible material may be brought up to
the top and sides of the unit and be covered
with ceramic tiles, bricks, rock or other suit-
able combustible finishing materials.
Note: The unit does not have to be complete-
ly enclosed in a chase. The clearance
on top of the unit is 0" to the standoffs
so combustible building materials can
be laid directly on top of the standoffs.
You must maintain clearance from the
vent to combustible materials for flex
for Simpson Dura-Vent, see page 7.
1) Determine the total thickness of facing
material (e.g. drywall plus ceramic tiles) to
allow the finished surface to be flush with
the front of the unit. Total facing thickness
can vary from 1/2" (13mm) to 1-1/4" (32mm)
thick.
6) Use steel studs for framing where the
1-1/2" (38mm) clearance from the vent
to combustible material cannot be main-
tained.
2) Frame in the enclosure for the unit with
framing material.

UNIT ASSEMBLY
PRIOR TO INSTALLATION
INSTALLATION
VENTING INTRODUCTION
The P33-3 uses the "balanced flue" 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.
There are 2 vent systems approved for use with the P33-3: the Regency Direct Vent System (Flex) for Horizontal Terminations only (see pages
11-12), and the Simpson Dura-Vent Systems for Horizontal and Vertical Terminations (see pages 13-24).
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. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited.
NOTE: Ensure compliance with the outside vent terminal location before cutting hole as both dimensions must be met.
For a facing material depth of
1-1/4"(32mm), the top facing
support must be reversed.

Note: To make the installation more aes-
thetically pleasing, we recommend
framing out a square to mount the
terminal to.
*If this is an outside corner, the minimum distance between the vent and the outside
corner is 6" (15cm) with AstroCap termination cap or 12" (30cm) with Dura-Vent
termination cap. See "F" on the diagram on page 10.
Note: A 2-1/2" (64mm) horizontal top and
1-1/2" (38mm) horizontal sides &
bottom clearance around the liner
must be maintained except that only
a 1" (25mm) clearance is needed at
the termination end. We recommend
framing a 10"(254mm) x 10"(254mm)
(inside dimensions) hole to give
structural rigidity for mounting the
termination.
Note: If installing termination on a siding
covered wall, furring strips must be
used to ensure that the termination
is not recessed into the siding.
2) Level the fireplace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3) Assemble the vent assembly by applying
Mill Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make this
easier). Apply Mill Pac or high temperature
silicone to the 6-7/8"(175mm) flex pipe and
slip it over the 6-7/8" outer collar of the vent
terminal at least 1-3/8"(35mm) and fasten
with the 3 screws.
4) Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
for 2 x 4 or 2 x 6 walls. The liners must slip
over the collars a minimum of 1-3/8".
5) Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6) Pull the centre 4"(100mm) liner and outer
6-7/8"(175mm) liner out enough to slip over
the flue collars of the fireplace.
7) Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 6-7/8"(175mm) liner.
9) Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check
vent termination area after snow falls,
and clear to prevent accidental block-
age of venting system. When using
snow blowers, make sure snow is
not directed towards vent termination
area.

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.
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.
