LEVELING
To level the hot plate, place a carpenter's level on the hot plate and check leveling of the unit side to
side and front to rear. Achieve leveling by turning each foot section of the unit's leg as needed. Turning
the foot in a counter clockwise direction will increase height and clockwise will decrease.
GAS PRESSURE REGULATOR
A preset gas pressure regulator and street elbow is shipped with the hot plate. This regulator must be
installed by an authorized service person before the unit is placed into operation. See full unit data plate
located on the side of the hot plate, for pressure regulator setting information. If a manometer is being
used, utilizing one of the available pressure taps in the manifold, the manifold pressure with one burner
on should be ± 0.3" W.C. of the value indicated on the rating plate.
1. Locate the gas connection pipe protruding through the back of the unit.
2. Cover the pipe threads with pipe joint compound resistant to propane gases.
3. Screw the regulator onto the pipe hand tight with flow direction arrow pointing towards the back of
the unit and the regulator adjustment in the up right position.
4. With a pipe wrench, tighten the regulator securely in the upright position. (The regulator is preset
and should not require any additional adjustments.) The pressure regulator must be mounted
horizontally to ensure the proper preset outlet pressure. If mounted in any other direction, the outlet
pressure must be rechecked and possibly reset. A leak limiter is supplied with every regulator to
allow excess gas pressure to escape. Do not obstruct the limiter or the gas regulator, as obstruction
may cause the regulator to malfunction.
GAS CONNECTIONS
All gas supply connections and any pipe joint compound used must be resistant to the action
of propane gases.
Prior to lighting, check all joints in the gas supply line for leaks. Use soap and
water solution. Do not use an open flame.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When test pressures exceed ½ psig (3.45 kPa), the hot plate and its individual shutoff valve must be
disconnected from the gas supply piping system.
When test pressures are ½ psig (3.45 kPa) or less, the hot plate must be isolated from the gas supply
system by closing its individual manual shutoff valve.
FLUE CONNECTIONS
DO NOT obstruct the flow of flue gases from the flue located on the rear of the hot plate. Proper
venting of flue gas is vital to the safe and efficient operation of the hot plate. Problems arising from the
intentional obstruction of the flue will result in voiding of warranty. It is recommended that the flue
