NATURAL GAS (NG) SAFETY OPERATING SPECS
Your Natural Gas (G20) Side burner is designed to use natural gas ONLY. The grill operates at
a pressure of 4” water column (wc) or 10 mbar set at the natural gas regulator attached at the
back of the grill. Prior to installing gas supply lines, check with your local gas utility or municipality
regarding local gas pressure and for building code requirements and instructions or consult a
licensed and knowledgeable installer.
GAS PLUMBING GUIDELINES:
1) Install an “ON-OFF” shutoff valve for OUTDOOR gas supply source after gas line piping exits
outside wall, or before gas piping enters ground.
2) Install an “ON-OFF” shutoff valve for INDOOR gas supply source to the branch fuel line in an
accessible location near the supply line.
3) Do not use Teflon ® tape or pipe sealant on any flare ends because you will not obtain a leak-free
seal.
4) Use only Pipe sealing compound or pipe thread tape of the type resistant to the action of natural
gas to at least the first three threads of all male pipe threads when making the connection.
5) Disconnect your gas grill from fuel source when the gas supply is being tested at high
pressures. This appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of that system at pressures in excess of 1/2
psig or 37 mbar.
6) Turn off your gas grill when the gas supply is being tested at low pressures. This appliance
must be isolated from the gas supply piping system by closing its individual valve.
BEWARE OF SPIDERS
CAUTION: BURNERS MUST BE INSPECTED AND CLEANED BEFORE FIRST USE.
Spiders and small insects occasionally spin webs or make nests in the burners during
warehousing, transit and/or after long periods of non- use. These webs can lead to a gas flow
obstruction, which could result in a fire in and around the burner tubes. This type of fire is
known as “FLASH-BACK” and can cause serious damage to your grill and create an unsafe
operating condition for the user. Although an obstructed burner tube is not the only cause of
“FLASH BACK” it is the most common cause, and frequent inspection and cleaning of the
burners is necessary.
WARNING: Gas valves are pre-set at the Bull factory to operate on LP Gas or Natural Gas. If you
wish to convert to a different gas type, other than LP or NG, be sure to contact your grill dealer,
licensed plumber or authorized service center for further details. Conversion kits are not sold to the
general public and require a professional to perform service. Failure to properly convert a unit can
cause serious injury to yourself and/or others, irreparable damage to your grill and void of warranty.
WARNING: IF THESE GUIDELINES ARE NOT FOLLOWED, FIRE CAUSING SERIOUS INJURY OR DEATH MAY OCCUR
