SAFETY INSTRUCTIONS
BEWARE OF CLOGGED BURNERS
DUE TO SPIDER WEBS
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 venturi 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 NEVER cover slots, holes or passage
in the grill bottom or cover an entire
cooking grate with material such as
aluminium foil. Doing so blocks air
flow through the oven and may cause
carbon monoxide poisoning.
Aluminium foil linings may trap heat causing
a fire hazard.

STALLION GRILL OPERATIONAL SAFETY, CONTINUED
DANGER! IF YOU SMELL GAS, FOLLOW THE GUIDELINES BELOW:
1) Visually check burner flame status, and pilot burner flame if provided.
2) NEVER test for gas leaks with a lighted match or open flame.
3) Shut off gas source to the appliance.
4) Extinguish any open flame.
5) Open grill lid to release any accumulation of fumes.
6) If gas odor persists, immediately contact your gas supplier or your fire department.
CHECKING FOR GAS LEAKS NEVER TEST FOR GAS LEAKS WHILE THE GRILL IS LIT!
It is a must that you use the steps below to check for leaks on LP Gas Grills prior to first use, start
of a new BBQ season and
whenever the gas cylinder is changed on LP Gas Grills.
1) Turn off heat control valve(s), and then turn on gas at source.
2) Make a soap solution by mixing one-part liquid detergent and one-part water.
3) Apply the soap solution to all gas connections: If ai r bubbles appear in the soap solution it
mea n s th e connections are not properly
sealed and need to be tighten or repaired as needed.
4) If you have a gas leak that you cannot repair, turn off the gas at the source, disconnect fuel line
from the grill and immediately
call your grill dealer and gas supplier for professional assistance.
WARNING: If these guidelines are not followed, fire causing serious injury or death may occur.

LIQUID PROPANE GAS TO NATURAL GAS CONVERSION
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.

10
NATURAL GAS (NG) SAFETY GUIDELINES
Your Natural Gas (G20) grill 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.
NATURAL 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.
Refer to the following instructions and illustrations for typical gas supply connections.
We strongly suggest professional installation and hook-up of the Gas BBQ. All regulators must meet EN16129 standard.
IMPORTANT: Before connecting grill to gas source, make sure BBQ Grill control knobs are in “OFF” position.
Be sure to follow instructions for connecting an appliance to a fixed fuel piping system specifying the use of a rigid pipe,
semi-rigid tubing, and/or a connector that complies with the Standard for Connectors for Outdoor Gas Appliances and
Manufactured Homes, ANSI Z21.75 For post-mounted outdoor cooking gas appliances, in-ground metallic posts shall be
protected against corrosion as warranted by soil conditions. A suitable coating of corrosion protection will retard the effects
of corrosion and help your Bull purchase last longer.
IMPORTANT: Bull Outdoor Products does not recommend the use of any quick connect fittings or lines to the unit. Use of
these types of fittings or lines could cause low gas flow and greatly reduce the performance of the unit.
1) Do not use Teflon tape or pipe sealant
on any flare ends because you will not
obtain a leak free seal.
2) Remove plastic cap from regulator
installed on grill.
3) Attach stainless steel flex line 3/8 flare
female end to the regulator and the
other end to a nipple to allow
connection to a shut-off valve to the
gas supply.
