INSTALLATION OF HOLD DOWN BRACKET
1. After installation of the cooktop, locate the two sheet metal screw holes on each end of the bottom of the burner
box. Screw hold down brackets (Item 1) using the #10 x 1/2”
sheet metal screw (Item 2) to the burner box.
2. Screw the eye bolt (Item 3) into the self-retaining nut (Item 4)
and tighten firmly aganist bottom of countertop.
GAS CONNECTION
The gas supply (service) line must be the same size or greater than the inlet line of the appliance. All cooktops use a
1/2” (1.3 cm) I.D. NPT (Sch40) inlet. Sealant on all pipe joints must be resistive to LP/Propane gas.
1. Manual shut-off valve:
The installer-supplied valve must be installed in the gas service line ahead of the appliance and regulator in the
gas stream and in a position where it can be reached quickly in the event of an emergency. IIn

A “T” handle type manual gas valve must be installed in the gas supply line to the appliance.
2. Pressure regulator:
a) All heavy-duty, commercial-type cooking equipment must have a pressure regulator on the incoming service
line for safe and efficient operation, since service pressure may fluctuate with local demand. The regulator
supplied with this cooktop must be installed before any gas connections are made.
b) Any conversions required must be performed by your dealer or a qualified licensed plumber or gas service
company. Please provide the service person with these manuals before the work is started on the cooktop.
(Gas conversions are the responsibility of the dealer or end user).
NOTE:
This cooktop is shipped from the
factory with fixed orifices, jets and fixed regulator. If you have ordered a natural gas cooktop and want to
convert to LP/Propane, you will need to order a conversion kit (LPK2-VGSU). See LP/Propane conversion in
this manual to convert to LP/Propane.
c) Manifold pressure should be checked with a manometer; natural gas requires 5.0” WCP and LP/Propane
requires 10.0” WCP. Incoming line pressure upstream for the regulator must be 1” WCP higher than the
manifold pressure in order to check the regulator. The regulator used on this cooktop can withstand a
maximum input pressure of 1/2 PSI (14.0” WCP). If the line pressure is in excess of that amount, a step-
down regulator will be required.
d) The appliance, its individual shut-off valve, and pressure regulator must be disconnected from the gas
supply piping system during any pressure testing of that system at pressures in excess of 1/2 PSI (3.45kPa).
e) The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2
PSI (3.45kPa).
3. Rigid Connections:
a) Incoming gas is brought from an intake pipe (not supplied) at the rear of the unit to the pressure regulator;
then to the manifold pipe for distribution. The only connection necessary is from the service supply, through
the shut-off valve (not supplied), to this intake pipe (not supplied) to the regulator supplied, but not
connected through the cooktop. IIn

flexible gas connector.
b) Double-check any installer-supplied intake pipes visually and/or blow them out with compressed air to clear
any dirt particles, threading chips, or other foreign matter before installing in a service line. Those particles
will clog orifices when gas pressure is applied.
c) Check the gas supply and the regulator for the proper supply of gas. A properly adjusted burner should be
stable and quiet. The flame should have a sharp, well defined blue inner cone with no yellow tipping. The
flame should also be stable and uniform with no flames lifting off the burner ports.
CAUTION:
Before placing the cooktop into operation, always check for gas leaks with a soapy water solution or other
acceptable method.
DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS!
