2M-Z16116, Ultra-Max Gas Hotplates
GAS PIPING
Gas piping shall be of such size and so installed as to provide a supply of gas sufcient to meet the
full gas input of the appliance. If the appliance is to be connected to existing piping, it shall be checked
to determine if it has adequate capacity. Joint compound shall be used sparingly and only on the male
threads of the pipe joints. Such compounds shall be resistant to the action of L.P. gases. WARNING:
Any loose dirt or metal particles which are allowed to enter the gas lines on this appliance will damage
the valve and affect its operation. When installing this appliance, all pipe and ttings must be free from
all internal loose dirt.
GAS PRESSURE REGULATOR
A convertible pressure regulator is provided with each hotplate. It should be connected to the inlet pipe
at the rear of the unit. The gas supply is then connected to it. The supply pressure to the regulator is not
to exceed 1/2 PSIG. It is shipped set for 5" water column manifold pressure for use with natural gas.
MANUAL SHUT OFF VALVE
A manual shut off valve should be installed upstream from the manifold and within six feet of the
hotplate.
CONNECTING GAS SUPPLY LINE
The gas inlet of the hotplate is sealed at the factory to prevent entry of dirt. Do not remove this seal until
the actual connection is made to the gas supply line.
PROPANE GAS - CONVERSION
This hotplate is equipped with xed orice hoods and is shipped from the factory for use with natural
gas. To convert to propane gas, install the burner orice hoods, located on the manifold, as follows:
1. Remove grates and burners.
2. Remove the burner orice hoods and install the orice hoods supplied.
3. Replace the burners and grates. Be sure venturi opening is positioned on valve orice.
4. Set manifold pressure to (10) inch water column. A 1/8" pipe plug on the burner manifold
can be removed for attaching a pressure gauge. Remove the slotted, or hex-threaded plug from
the pressure regulator. Invert the plug and re-install. The letters "LP" should now be visible on
the plug. The regulator is now set for 10" (25.4 cm) water column. Attach the conversion label,
supplied with the unit, close to the nameplate on the top side of the front panel. Pilot ame may
need to be adjusted for LP gas.
CHECKING FOR GAS LEAKS
Check entire piping system for leaks. Soap and water solution or other material acceptable for the
purpose, shall be used in locating gas leakage.
Matches, candle ame or other sources of ignition shall not be used for locating gas
leaks.
PILOT LIGHTING INSTRUCTIONS
The hotplate is equipped with factory pre-set standing pilots and should be lit immediately after the gas
is turned on. Pilot lights may need an adjustment based on local gas supplies. See below for pilot light
adjustments.
If the operator smells gas or the pilot lights need to be relit:
1. Turn off main valve to unit.
2. Turn off all knobs and pilot valves and wait 5 minutes to clear gas.
3. The pilot lights on this hotplate can be adjusted by turning the adjustable screw
counterclockwise to open and clockwise to close.
4. Turn on main valve and light all pilots.
5. Adjust pilot light ames as small as possible around pilot head, usually about 1/4" high,
but high enough to light burner immediately when burner valve is turned on high.
6. Turn burner knobs to desired setting.
7. To turn burners off, turn knobs clockwise to "OFF."
If interuption of the gas supply occurs, reliting of the pilot light will be needed.
