INSTALLATION Continued
6. When pressure testing the gas supply piping to a
maximum of ½ psi (14” WC, 34.9mbar), the appliance
must be isolated from the supply line by closing the
manual shut-off valve.
7. To ensure optimal operation of this unit, it is
recommended that the dynamic gas supply pressure into
the appliance regulator is a minimum of 1” WC(2.5mbar)
higher than the pressure stated on the rating plate.
Start Up
1. Inside the unit, ensure the burners are in the correct
position and the shields hanging under the burners have
not rotated out of position during transit.
2. Install cast radiants over each burner and place the
cooking grates in position on the unit.
3. Ensure the gas supply to the appliance is open and the
unit is connected to the power supply. Activating the
one or two power switches on the right leg operates the
unit.
4. Check all gas connections for leaks using a soap solution.
Do not use an open fl ame to check for leaks. Be sure
to inspect connections outside and inside the unit (ie:
valves, manifold fi ttings and connections in the left leg
channel) to make certain all connections are gas tight
after shipping.
5. Verify the unit is running at the pressure stated on the
rating plate as follows:
FOR HEEGM24 & 36 SIZE UNITS
• Connect a manometer to the test spigot on the
manifold.
• Turn on the unit and adjust the burners so that they are
all set to high.
• If necessary, adjust the pressure so that the reading
on the manometer matches the pressure value stated
on the rating plate. To adjust the pressure, access and
rotate the pressure adjustment screw on the regulator
installed at the appliance.
FOR HEEGM48 & 60 SIZE UNITS
• Connect a manometer to the test spigot on the LEFT
manifold.
• Turn on the LEFT side of the unit only (by activating
the left switch) and adjust the burners so that they are
all set to high.
• If necessary, adjust the pressure so that the reading
on the manometer matches the pressure value stated
on the rating plate. To adjust the pressure, access and
rotate the pressure adjustment screw on the regulator
installed at the appliance.
6. Inspect the fl ame of each burner to determine whether
adjustments to the burner air shutter are necessary.
Adjustments are made by loosening the air shutter screw;
rotating the shutter and re-tightening the screw. If the
tips of the fl ame appear too yellow, the shutter should
be turned to allow MORE air to enter the burner cavity. If
the fl ames appear to be lifting off the burner ports, the
shutter should be turned to allow LESS air to enter the
burner cavity.
