Figure 14 - ROUTE GAS LINE
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 7 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.

Notes:
• All appliances are factory-equipped with a
flexible gas line connector and 1/2 inch shutoff
valve (see Figure 47 on Page 27).
• 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 27).
• 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 47). Appliances using
Propane should have a sediment trap at the
base of the tank.
• Check with local building of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 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 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 con-
nector and 1/2 inch shutoff valve (see Step
6 on Page 27).
