GAS CONNECTION
The gas connection is a 3/8" NPT 90
o
elbow. The
gas line can be rigid pipe or to make installation
easier, use a listed flexible connector and/or
copper tubing if allowed by local codes. Since
some municipalities have additional local codes
it is always best to consult with your local
authorities and the CAN/CGA B149 installation
codes.
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
burner and/or valve servicing. Flare nuts for
copper lines and flex connectors are usually
considered to meet this requirement.
I
mportant: Always check for gas leaks
with a soap and water solution or gas leak
detector. Do not use open flame for leak
testing.
Note: Prior to any pressure testing of
the gas supply piping system that
exceeds test pressures of 1/2 psig,
this appliance must be disconnect-
ed from the piping system. If test
pressures equal to or less than 1/
2 psig are used then this appliance
must be isolated from the piping
system by closing its individual
manual shut-off valve during the
testing.
HIGH ELEVATION
This unit (at 38,000 Btu/h) is approved in Can-
ada for altitude 2000 ft. to 4500 ft. (CAN/CGA-
2.17-M91) with the orifice kit Part # 621-975. For
Natural Gas installations above 4500 ft. follow
current CAN/CGA-B149.1.
In U.S.A., for installations above 2000 ft. refer
to current ANSI Z223.1 Sc8-8.1.2a appendix F,
for resizing orifice.
INSTALLATION
Diagram 9
9) Slide the Wall Thimble Cover (Part # 940)
over the Retro Connector and secure with
masonry bolts. Diagram 10. If you have a
framed wall in front of the masonry, use
wood screws to mount the Wall Thimble
Cover to the framed wall, over the Retro
Connector and the 10" (254mm) square
framed opening. Diagram 11. If needed, add
a section of direct vent pipe to the Retro
Connector in order to extend through the
opening in the Wall Thimble Cover.

Diagram 11
10) The connection between the appliance and
the Retro Connector may be completed with
a section of black direct vent pipe, together
with an adjustable length pipe section.
