ENCLOSURE REQUIREMENTS

Ventilation Requirements

VENTILATION (ALL ENCLOSURES)
For All Piping Systems and All Gas Types: (Natural

Gas, Household Propane, L.P. Cylinder)
FOR YOUR SAFETY, you must provide the openings

listed below for replacement air and cross-ventilation
of the unit enclosure.

One side of the enclosure shall be left completely
open to the outside; OR 4 (minimum) ventilation
openings MUST be created (reference Fig. 1):

Each opening must have a minimum of 10 sq. in. of
free area. The openings must be equally sized and
unobstructed.

Two openings must be in the side walls of the enclosure,

at the top level, and spaced at 180 degrees. The openings

must begin 1" or less below the countertop level and end
no more than 5" below the countertop level.

Two openings must be in the side walls of the enclosure,
at the oor level, and spaced at 180 degrees.The openings
must begin 1" or less above the oor level and end no
more than 5" above the oor level.

To achieve the proper ventilation, you may use venting
panels as shown. Contact your dealer.

KEEP THE VENT OPENINGS AND SURROUNDING
AREA OF THE ENCLOSURE CLEAN AND FREE OF
OBSTRUCTIONS AT ALL TIMES.

WARNING: Ventilation openings in side walls shall not

communicate directly with other enclosures of the outdoor
cooking gas appliance.

WHEN A PROPANE (L.P.) CYLINDER IS USED IN THE
ENCLOSURE

When a propane (L.P.) cylinder is installed inside of the
enclosure, the guidelines below MUST be followed.
FAILURE TO DO SO MAY CAUSE DAMAGE TO YOUR
UNIT AND/OR PERSONAL INJURY. Reference Fig. 2 for
an example.

• A non-combustible heatshield must be installed to

protect the regulator/hose assembly and propane

cylinder valve.

• Many dealers offer propane tank door with tank tray
models and a propane tank heatshield that rests
directly on the tank to meet the cylinder install
requirements. Propane tank door with tank tray
shown in Fig. 3. Contact your dealer for ordering
information.

• 4 openings minium with 2 per side wall, spaced at 180º.

• Top openings within 5” of countertop

• Bottom openings withing 5” of floor.

GRILL MAINTENANCE & SAFETY

1. The outdoor grill and surrounding area MUST

remain clear of ammable substances such
as gasoline, yard debris, wood, etc.

2. The airow through the vent space located
below the control panel must remain
unobstructed.

3. When using propane gas:
a. The required ventilation openings in the

enclosure must be clear of debris. See the

PROPANE SAFETY INFORMATION section.

b. The propane cylinder, regulator, and rubber
hose must be in a location not subject to
temperature above 125° F (51° C).

4. The ames on each burner burn evenly along
the entire burner with a steady ame (mostly
blue). If burner ames are not normal, check
and clean the orice and burner/venturi tubes
for insects and insect nests. A clogged tube
can lead to a re beneath the grill. A proper
ame pattern will ensure safe operation and

optimal performance.

5. The in-line gas valve or gas cylinder valve

must always be shut OFF when the grill is not

in use.

6. The drip collector holes must be clear and

unobstructed. Excessive grease deposits can
result in a grease re.

7. Whenever reconnecting any wires, apply a
small amount of dielectric grease to the male
connector, then make the connection. This
will ensure conductivity and prevent moisture
from affecting the contact.

IMPORTANT
IN THE EVENT OF A GREASE FIRE, IMMEDIATELY SHUT OFF THE MAIN GAS VALVE TO THE
UNIT. KEEP THE LID OPEN AND ALLOW THE FIRE TO EXTINGUISH ITSELF. A THOROUGH
INSPECTION BY A TRAINED SERVICE TECHNICIAN SHOULD BE CONDUCTED BEFORE
FUTURE USE OF YOUR UNIT. THE SERVICE TECHNICIAN WILL CHECK THE SYSTEM FOR
GAS LEAKS AND WILL CHECK ALL ELECTRICAL WIRING FOR DAMAGE. ALL GAS LEAKS
AND WIRING MUST BE REPAIRED PRIOR TO FUTURE USE.

WARNING: NEVER cover the entire cooking or grill surface with griddles or pans.

Overheating will occur, and burners will not perform properly when combustion heat is

trapped below the cooking surface.

CAUTION: NEVER spray water on a hot gas unit.
