Regency P33-3 Zero Clearance Direct Vent Gas Fireplace
INSTALLATION
GAS LINE
INSTALLATION
The gas line is brought through the right side of
the appliance. The gas valve is situated on the
right hand side of the unit and the gas inlet is
on the right hand side of the valve.
The gas line connection may be made of rigid
pipe, copper pipe or an approved fl ex connec-
tor. (If you are using rigid pipe, ensure that the
valve can be removed for servicing.) Since some
municipalities have additional local codes it is
always best to consult with your local authorities
and the CAN/CGA B149 installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
connectors are usually considered to meet this
requirement.

Diagram 3: The upper half of the fl ashing is
installed under the roofi ng material and not
nailed down until the chimney is installed. This
allows for small adjustments.

VERTICAL
TERMINATION
1)
Maintain the 1-1/2" clearances (air spaces)
to combustibles when passing through ceil-
ings, walls, roofs, enclosures, attic rafter,
or other nearby combustible surfaces. Do
not pack air spaces with insulation. Check
pages 13-17 for the maximum vertical rise
of the venting system and the
maximum horizontal offset
limitations.
2)
Set the gas appliance in its
desired location. Drop a plumb
bob down from the ceiling to
the position of the appliance
fl ue exit, and mark the location
where the vent will penetrate
the ceiling. Drill a small hole
at this point. Next, drop a
plumb bob from the roof to
the hole previously drilled
in the ceiling, and mark
the spot where the vent
will penetrate the roof.
3)
A Firestop spacer must be installed in the
fl oor or ceiling of every level. To install the
Firestop spacer in a fl at ceiling or wall, cut
a 10 inch square hole. Frame the hole as
shown in Diagram 2 and install the fi re-
stop.

Note: Apply sealant "Mill-Pac" to inner pipe
and high temperature silicone seal-
ant to outer pipe on every twist-lock
joint.
pipe into the vent cap assembly. It is
important that the vent pipe extends into
the vent cap suffi cient distance so as to
result in a minimum pipe overlap of 1-1/4
inches. Secure the connection between the
vent pipe and the vent cap 3 sheet metal
screws.
9)
Install wall thimble in the center of the
10" square and attach with wood screws
(Diagram 4).
4)
Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
5)
Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of suffi cient size to meet
the minimum requirements for clearance
to combustibles of 1-1/2". Slip the fl ashing
under the shingles (shingles should overlap
half the fl ashing) as per Diagram 3.
6)
Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to
avoid obstructions, it is important to
support the vent pipe every 3 feet, to
avoid excessive stress on the elbows,
and possible separation. Wall straps
are available for this purpose.
Galvanized pipe is desirable above the roofl ine
due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until
the height of the vent cap meets the minimum
height requirements specifi ed in Dia. 4 or local
codes. Note that for steep roof pitches, the
vertical height must be increased. A poor
draft, or down drafting can result from high
wind conditions near big trees or adjoining
roof lines, in these cases, increasing the
vent height may solve the problem.
7)
Ensure vent is vertical and secure the base
of the fl ashing to the roof with roofi ng rails,
slide storm collar over the pipe section and
seal with a mastic.
8)
Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces, which
the vent passes through must be en-
closed.

Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open fl ame for leak testing.
