Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line to the left side
of the appliance as shown in Figure 15. 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 29).
Also see Figures 13 and 14.
Figure 15 - 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 requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CSA-B149.1
- latest edition (Canada).
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.

Notes:
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see Figure 50 on Page 31).
• 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 29).
• 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. 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
penetrations of the gas line allowed?, etc).
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Installation and Operation Instructions
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.

Top Vent Installations - See Figure 16
Side Vent Installations - See Figure 17
Preparing the Appliance Vent Collar
Each of the appliances' two vent collars are
sealed with a seal cap which must be removed
from the vent collar being used. In top vent
installation the cover plate shall be removed
from the inside. Refer to Figure 16 for top
vent installations and Figure 17 for side vent
installations and the following steps to prepare
the appropriate collar for use.
From the vent collar being used, remove the
two screws securing the vent seal cap. Twist
the cap counterclockwise. Pull it away from
the appliance and discard, along with the piece
of insulation.
