Tip: Install hold down bracket without the adjusting
screw installed. Turn hold down brackets flush with the
sides of the cutout. This will help with inserting cooktop in
hard-to-reach spaces.
Connect Gas Supply
The gas inlet to the unit is located at the right rear of the
cooktop.
Install the pressure regulator (supplied with unit) to
manifold pipe using Teflon tape on threads of manifold
pipe. Turn to hand tighten plus 1/4 turn, not exceeding 1
turn for alignment. To prevent possible damage to the
gas pressure regulator, install it after the cooktop is in its
permanent position. When the regulator is securely
installed on the manifold pipe, the conversion nut will be
easily accessible.
Pressure Regulator
9 WARNING
Do not attempt any adjustment of the pressure
regulator, except when converting to propane.
Adjustments could lead to leaks or cause incorrect
gas pressure to the appliance.

Gas and Electrical Location
Connect the gas supply line to the unit pressure
regulator using a 1/2” flex gas line connector between
manual shut-off valve and pressure regulator. Always use
a new flex line.
Check supply line connections for leaks using a soap
solution or non-corrosive leak detection fluid. Do not use
a flame of any sort.
1. Turn on gas.
2. Apply a soap solution or non-corrosive leak detection
fluid to all joints and fittings in the gas connection
between the shut-off valve and the cooktop. Include
gas fittings and joints in the cooktop if connections
may have been disturbed during installation. Bubbles
appearing around fittings and connections indicate a
leak.
3. If a leak appears, turn off supply line gas shut-off valve
and tighten connections.
4. Retest for leaks by turning on the supply line gas shut-
off valve. When leak check is complete (no bubbles
appear), test is complete.
5. Wipe off all soap solution or detection fluid residue.
