P33CE-11 Direct Vent Gas Fireplace

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 flex connector. (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 flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for servicing.
Flare nuts for copper lines and flex connectors are
usually considered to meet this requirement.
Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open flame for leak testing.

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

Unit Installation with Vertical
Termination
1)
Maintain the 1-1/2" clearances (air spaces) to
combustibles when passing through ceilings,
walls, roofs, enclosures, attic rafter, or other
nearby combustible surfaces. Do not pack
air spaces with insulation. Check "Venting"
Sections for the maximum vertical rise of the
venting system and the maximum horizontal
offset limitations.
2)
Set the gas appliance
i n
its desired location. Drop
a
plumb bob down from the
ceiling to the position of
the appliance flue exit, and
mark the location where the
vent will penetrate the ceil-
ing. 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 floor
or ceiling of every level. To install the Firestop
spacer in a flat ceiling or wall, cut a 10 inch
square hole. Frame the hole as shown in
Diagram 2 and install the firestop.
4)
Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow con-
nections are in the fully twist-locked position
and sealed.
Diagram 4
NOTE:
For best results and optimum perfor-
mance with each approved venting system, it is
highly recommended to apply “Mill-Pac” sealant
(supplied) to every inner pipe connection. Failure
to do so may result in drafting or performance
issues not covered under warranty.
8)
Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into the
vent cap assembly. It is important that the vent
pipe extends into the vent cap sufficient 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).
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 sufficient size to meet
the minimum requirements for clearance to
combustibles of 1-1/2". Slip the flashing under
the shingles (shingles should overlap half the
flashing) 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 roofline
due to its higher corrosion resistance. Continue
to add pipe sections through the flashing until
the height of the vent cap meets the minimum
height requirements specified 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 flashing to the roof with roofing 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
enclosed.
