Verify Package Contents

•  Hold down brackets (2)
•  Grates (3)
•  Burner sets (5)
•  Gas pressure regulator with 3/4” to 1/2” reducer
•  Stainless steel cleaner

Installing the Cooktop

•  Verify that the power supply meets the specifications 

on page 4 before proceeding.

•  To prevent damage to the gas pressure regulator, 

install it only after the cooktop is mounted in its perma-

nent position.

•  Do not over-tighten the hold down bolts. Over-

tightening the hold down bolts may result in improper 

operation of the dual gas burners.

•  Do not use a hardening compound or caulk to perma-

nently seal the cooktop into place. The cooktop must 

be readily removable if service is required. Removal 

of sealant to service the unit will be performed at the 

customer’s expense.

1.  If the cooktop will be used with a raised vent, install the 

vent according to it’s installation instructions first.

2.  Lower the cooktop into the cutout. Slide it forward as 

far as possible and center it side to side.  

3.  Secure the cooktop to the countertop using the two (2) 

provided hold-down brackets as shown.

Installation Instructions

Connecting the Gas Line

•  Verify that the gas supply meets specifications before 

connection. See page 4.

•  Do not install the cooktop without also installing the 

included gas regulator. Do not use the cooktop without 

the regulator installed.

•  Ensure that the arrow on the regulator points in the 

direction of the gas flow, towards the cooktop.

•  Do not apply excessive pressure when tightening gas 

connections and fittings.

•  Do not use Teflon tape, pipe thread sealant or any 

other sealing compound on the seat of flared gas line 

connections.

•  Test the gas lines for leaks as instructed before use. 

Do not use a flame to check for leaks. 

•  The maximum gas supply pressure to the regulator 

must never exceed 1/2 psi (3.5 kPa).

•  The cooktop and shut-off valve must be disconnected 

from the gas supply piping system during any pres-

sure testing exceeding 1/2 psi (3.5 kPa).

•  The cooktop must be isolated from the gas supply pip-

ing system by closing the shut-off valve to the cooktop 

during any gas supply piping system pressure testing 

equal to or less than 1/2 psi (3.5 kPa).

•  For LP gas installations, the LP gas tank must have its 

own high-pressure regulator in addition to the pressure 

regulator supplied with the cooktop.

1.  Attach the gas pressure regulator (included with the 

cooktop) to the cooktop pipe nipple inlet. For tight 

installations, the regulator may be installed upstream 

from the pipe nipple, anywhere between the shut-off 

valve and the cooktop. For best performance, minimize 

gas pressure loss by attaching the regulator as close 

as possible to the cooktop gas inlet.

2.  Complete connection of the gas supply to the cooktop 

by installing a minimum 1/2” flexible gas line (not 

included) between the pressure regulator and the shut-

off valve.

3.  Check for gas leaks:

◊  Turn all cooktop control valves to the 

OFF position.

◊  Turn on the gas supply valve and check all lines 

and connections for leaks using a soap and water 

solution or a gas leak detector.

◊  Turn the gas supply off.
