UNIT ASSEMBLY PRIOR TO INSTALLATION
INSTALLATION
VENTING INTRODUCTION
The P33-4 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 5 vent systems approved for use with the P33-4: the Regency®Direct Vent Flex System for Horizontal Terminations only and the Simpson
Dura-Vent, Selkirk Direct-Temp, Amerivent Direct Vent and Security Secure Vent Systems for Horizontal and Vertical Terminations (see following
"Venting" Sections for more details).
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.
(See "Rigid Pipe Venting System" for more details and exceptions).
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.

IMPORTANT
If using any Cabinet Mantels with Part #
510956, 510958, 510962, 510964 and
510834 the wall thimble must be secured first
and venting must be attached to unit before
sliding into final position.
Also Rigid Vent venting cannot be used with
any of the mantels noted above. See Price
Pages for alternative options.
Wherever necessary due to
external location of cap, the
AstroCap can be replaced with
the FPI Riser Vent Termination
Cap or the Dura-Vent Snorkel
Termination Cap.
INSTALLATION
REGENCY®DIRECT VENT FLEX SYSTEM
Horizontal Terminations Only
This venting system, in combination with the P33-4 Direct Vent Gas Fireplace, have been tested and listed as a direct vent heater system by Warnock
Hersey. The location of the termination cap must conform to the requirements in the "Exterior Vent Terminal Locations" Section .
Regency®Direct Vent Flex Termination Kit (Part # 946-513) includes all the parts needed to install the P33-4 with a maximum run of 2
feet. If installing the P33 with a continuous vent length of more than 2 ft (.6m) to a maximum of 10 ft. (3.0m) use Kit # 946-515 (4 ft) or 946-516
(10 ft) or see "Rigid Pipe Venting Systems" Section for alternate venting arrangements.

INSTALLATION PROCEDURES
for Regency®Direct Vent System (Flex)
Minimum and Maximum Vent Clearances
INSTALLATION
1) Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
Note: To make the installation more
aestheticallypleasing,werecommend
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" in the diagram in "Exterior Vent Trmination Locations"
Section.
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 framing
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
blockage 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.
