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
requirements outlined in the National Fuel Gas
Code, NFPA 54—latest edition (USA) or CAN/
CGA-B149.1—latest edition (Canada).
NOTES:
• All appliances are factory-equipped with a
flexible gas line connector and 1/2" shutoff
valve (see Figure 36 on Page 25).
• See Massachusetts Requirements on Page
6 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 25).
• 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 36 on Page 25).
• Check with local building official for local
code requirements.
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 insufficient 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.

Step 2. ROUTING GAS LINE
Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Figure
13. Gas lines must be routed, constructed and
made of materials that are in strict accordance
with local codes and regulations.
All appliances are factory-equipped with a
flexible gas line connector and 1/2" shutoff
valve. (See Step 6 on Page 24).
The incoming gas line should be piped into the
valve compartment and connected in one of the
two methods as shown in Figure 36 on Page 25.
Never use galvanized or plastic pipe. Refer to
Table 6 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 qualified individual such as a plumber
or gas fitter 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 unqualified should attempt sizing
or installing gas piping.
