The control panel MUST remain removable for servicing (see
CONTROL PANEL REMOVAL section).
COMBUSTION AIR AND COOLING AIRFLOW
Proper airflow (front-to-back, Fig. 10-1) MUST be maintained for the
unit to perform as it was designed. If airflow is blocked, overheating
and poor combustion will result. Do not block the 1" front air inlet along
the bottom of the control panel.
CAUTION:
Wind blowing into or across the rear oven lid vent (Fig.
10-3) can cause poor performance and/or dangerous
overheating. Orient the grill so that the prevailing wind
blows toward the front of the grill (Fig. 10-2).
A wind
deflector is available for purchase to assist in
proper airflow during windy conditions.
See Table
1 for model numbers. Follow the instructions included
with the wind deflector for installation.
GAS-SUPPLY PLUMBING REQUIREMENTS
For natural gas or a household propane system, rigid
1
/
2
" or
3
/
4
" black
steel pipe or local code-approved pipe is required to conduct the gas
supply to the unit. Contact your local gas supplier. Connect this pipe
to the C.S.A.-approved quick connect hose (attached).
Apply only joint
compounds that are resistant to all gasses on all NPT pipe fittings
except flare fittings
. Make sure to tighten all fittings securely.
Note:
If

" pipe is used with
natural gas
, it should be no longer
than 20'.
Important:
A shut-off valve (not included) in the gas line is
required.
It provides for safety when the unit is not
in use and for convenient maintenance and repair.
It must be installed within 6 feet of the unit and must
be easily accessible. Use a pipe joint compound
resistant to all gasses on all male fittings except flare
fittings.
GAS SUPPLY AND MANIFOLD PRESSURES:
For
natural gas
- normal 7" water column (w.c.), minimum 5", maximum

propane gas
- normal 11" w.c., minimum 10", maximum 13".
GAS-SUPPLY PLUMBING REQUIREMENTS
The gas supply is to be brought up near/behind the unit. Your individual
installation may vary.
Observe the National Fuel Gas Code and all
local codes. Leak test at all connections.
The gas supply must be sized to provide minimum inlet pressure
at the maximum flow rate (BTU/hr).
Undue pressure loss will occur
if the pipe is too small, or the run is too long. Gas supply pipe must be
½
" minimum interior diameter. If the gas line is longer than 20', a larger
diameter line may be necessary. Refer to the NFPA 54 guidelines for
further details.
Any rigid pipe gas line MUST stop outside of and near the unit. It
CANNOT be routed inside the cabinet of the unit. For natural gas
models, a quick disconnect hose is included and pre-installed to the
valve manifold, and routes out of the cabinet. For household propane,
an appropriate, C.S.A. approved, flexible hose or similar MUST be
purchased to route from the unit valve manifold out to the gas line.
The R.H.P. quick disconnect hose is recommended, and is discussed
and illustrated in this manual (see INSTALLATION and PARTS
LIST sections). Contact your dealer for ordering information. (If your
household propane setup varies from what is shown,
observe the
National Fuel Gas Code and all local codes.
)
Use a pipe joint compound resistant to all gasses on all NPT pipe
fittings. Make sure to tighten every fitting securely.
Do not use pipe
joint compound to connect flare fittings.
