Installation
Prior to connecting the regulator, check the incoming line pressure. The regulator can only withstand a
maximum pressure of ½ PSI (14” WC). If the line pressure is beyond this limit, a step down the regulator
before the regulator provided will be required. The arrow on the bottom shows gas ow direction and should
point downstream to the equipment.
LIGHTING THE PILOT
The manifold units are equipped with standing pilots and each should be lit immediately after the gas is
supplied to the equipment.
1. Before attempting to light the pilots, turn off the main gas valve to the equipment and wait 5 minutes to
clear the gas.
2. Turn off all gas control knobs.
3. Turn on control valve and light all pilots.
4. The pilot burner must be lit at the end of the tube. Hold an ignition source through the pilot light hole in the
front panel at the pilot tube. When the ame ignites remove ignition source.
5. Turn off the main gas valve to shut down the equipment.
Smoke appearing on initial use of the equipment is normal. This is a result of the rust preventative coating
burning off. Allow the equipment to “burn in” for at least 15 minutes before the rst use.

PRESSURE REGULATOR
• All commercial cooking equipment must have a pressure regulator on the incoming service line for safe and
efcient operation. The regulator provided for this equipment is adaptable for both Natural gas and LP gas.
• Regulator specications: ¾” NPT inlet and outlet, factory adjusted for 5” WC Natural Gas standard and may
be converted by qualied personnel to be used for Propane at 10” WC.

PILOT FLAME REGULATION
• The pilot ame on the equipment has been factory adjusted. When adjustment is necessary, adjust the pilot
ames as small as possible but high enough to light the burner. Immediately after, turn the burner valve to
the highest setting. Access to the pilot ame adjustment screw is obtained by removing the front panel.
BURNER ADJUSTMENT
• Remove the front panel to gain access. Turn burner valve knob to highest setting. Slowly decrease mixing
ring aperture to give a soft blue ame having luminous tips. Then slowly increase opening to a point where
the yellow tips disappear and a hard blue ame is obtained.
Before initial use, turn the gas control knob to the maximum setting and allow the equipment to burn-in for 15
minutes. Seeing smoke coming from the cooking surface is normal during burn-in. After 15 minutes of burn-in,
equipment is ready for use.
1. Hold the leg and rotate the adjustable feet so the equipment is level.
2. Check the drip tray frequently and add water as necessary.
3. To ignite the burner, press and turn the gas control knob to high position.
4. Allow the equipment to pre-heat before attempting to use.
5. Adjust the valve set-point to obtain the desired level of heat.
• A qualied service company should check the unit for safe and efcient operation on an annual basis.
• Gas piping shall be a certain size and installed to provide a supply of gas sufcient to meet the full gas
input of the equipment.
• A manual shut off valve should be installed upstream from the manifold within 4 ft. (1.2m) of the equipment
and in a position where it can be reached in the event of an emergency.
• Check entire gas piping system for leaks every so often. Using a gas leak detector or soapy water solution
is recommended.
• Install equipment under efcient exhaust hood with ameproof lters with a distance of no less than 4 feet
between the top of the equipment and the lters or any other combustible materials.
CLEANING
To maintain the appearance and increase the service life, clean your equipment daily. DO NOT clean

Instructions for Field Conversion between LP & NG
CAUTION: ENSURE THE GAS SUPPLY IS SHUT OFF AT THE MANUAL SHUT OFF
VALVE BEFORE PROCEEDING WITH THE CONVERSION.
1. Switch off the gas at the main supply valve and allow the unit to cool down before commencing with the
conversion.
2. Lift off the complete grill plate assembly to expose the burners and valves.
3. Remove the burners by loosening the fastening nuts located under the rear of the burner, lift the rear of the
burner and slide backwards.
4. The brass orice located on the end of the control valve may now be loosened and removed using a 1/2”
wrench. Replace with the new orice from the conversion kit, rst applying a small amount of jointing paste
to the threat on the end of the valve, this will ensure a good gas tight seal.
5. Replace the burner by sliding the open end over the orice and then locating the M5 stud through the slot
in the support bracket. Secure by replacing the M5 nut.
6. Replace the burner by sliding the open end over the orice and then locating the M5 stud through the slot
in the support bracket. Secure by replacing the M5 nut.
7. To operate with LP gas the regulator must be changed to operate at 10” WC. To do this remove the
converter cap and pin from the regulator, remove the pin and invert then reinstall in the cap. Replace the
cap on the regulator taking care that the gasket is in place on the cap.
8. Prior to connecting the regulator, check the incoming line pressure, as the regulators can only withstand a
maximum pressure of 1/2 PSI (13” WC). If the line pressure is beyond this limit, a step down regulator will
be required. The arrow forged into the bottom of the regulator body shows gas ow direction, and should
point downstream to the appliance.
9. Check for gas leaks regularly. A soapy water solution is recommended for locating gas leakage. Matches,
candle ame or other sources of ignition shall not be used for this purpose.
10. Replace the loose tting grill plate assembly into position.
11. Fix the conversion rating plate supplied in the kit adjacent to the original rating plate on the rear of the unit.
Fill in the details required on the installation plate and x to the rear of the unit.
