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/CSA-B149.1
- latest edition (Canada).
Notes:
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see
Figure 37 on Page 22).
• 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 22).
• 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 37). Appliances using
propane should have a sediment trap at the
base of the tank.
• Check with local building official for local
code requirements (i.e. are below grade pen
-
etrations 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 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
14. 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 inch shutoff
valve.
(See Step 6 on Page 22).
The incoming gas line should be piped into
the valve compartment and connected in one
of the two methods as shown in Figure 37 on
Page 22.
Never use galvanized or plastic pipe. Refer
to
Table 6 for proper sizing of the gas sup-
ply 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.
