• Venting requirements for rear vent applications in corner installations, the horizontal vent length
“a” to “b,” must not exceed 28 inches (711).
• Dimensions D and F occur when one 45 degree elbow is connected directly to the appliance collar.

• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see Figure 46). Appliances using
Propane should have a sediment trap at the
base of the tank.
• Check with local building offi cial for local code
requirements (i.e. are below grade penetrations
of the gas line allowed?, etc).
IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insuffi cient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.
Proper Sizing of Gas Line
Properly size and route the gas supply line
from the supply regulator to the area where
the appliance is to be installed per require-
ments outlined in the National Fuel Gas Code,
NFPA 54 - latest edition (USA) or B149 - latest
edition (Canada).
Never use galvanized or plastic pipe. Refer to
Table 9 for proper sizing of the gas supply line,
if black iron pipe is being used. Gas lines must
be routed, constructed and made of materials
that are in strict accordance with local codes
and regulations. We recommend that a quali-
fi ed individual such as a plumber or gas fi tter
be hired to correctly size and route the gas
supply line to the appliance. Installing a gas
supply line from the fuel supply to the appliance
involves numerous considerations of materials,
protection, sizing, locations, controls, pressure,
sediment, and more. Certainly no one unfamiliar
and unqualifi ed should attempt sizing or install-
ing gas piping.
Notes:
• All appliances are factory-equipped with a
fl exible gas line connector and 1/2 inch shutoff
valve (see Figure 46 on Page 26 ).
• See Massachusetts Requirements on Page 4
for additional requirements for installations in
the state of Massachusetts in the USA.
• The gas supply line should Not be connected
to the appliance until Step 6 (Page 26).
