Primo Water G420C Installation Instructions And Owner's Manual page 12

INSTALLATION REQUIREMENTS
The control panel MUST remain removable for servicing (see PARTS LIST).
ENSURE PROPER COMBUSTION AIR AND COOLING AIRFLOW
Proper airflow MUST be maintained for the grill to perform as it was designed. If airflow is blocked,
overheating and poor combustion will result. Do not block air inlet along the bottom of the control
panel or more than 75% of the cooking grid surface with pans or griddles.
Note: The 1" (2.5 cm) front air space also allows access to the drip tray.
GAS-SUPPLY PLUMBING REQUIREMENTS
For natural gas or a household propane system, rigid 1/2" (1.3 cm) or 3/4" (1.9 cm) 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 required C.S.A.-approved stainless-steel flex connector (attached).
An NPT adapter has been provided for 1/2" pipe. DO NOT use a rubber hose within the grill
enclosure. Apply only joint compounds that are resistant to all gasses to all male pipe fittings except
flare fittings. Make sure to tighten every joint securely.
Note: If 1/2" (1.3 cm) pipe is used with natural gas, it should be no longer than 20' (6.1 meters).
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. 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" (17.78 cm) water column (w.c.), minimum 5" (12.7 cm), maximum 10 1/2"
(26.7 cm). For propane gas - normal 11" w.c., minimum 10" (25.4 cm), maximum 13" (33 cm).
