WARNING: Cooktop model ZGU375NS is shipped
from the factory set to operate only with natural
gas. Do not use with LPG. If you wish to use
LPG, you must have cooktop model ZGU375LS.
These cooktops are designed to operate on natural
gas at 4 in. of water column pressure or on LP gas
at 10 in. of water column pressure, depending on
model. For proper operation, the maximum inlet
pressure to the regulator must be no more than
10 in. of water column pressure for natural gas
and 14 in. of water column pressure for LP gas.

Gas Supply Shutoff Valve
The cooktop itself is not equipped with a gas shut-
off valve. If installed correctly, a shutoff valve will be
in the main gas supply line "upstream" of the
appliance pressure regulator.
Measuring the Gas Pressure
Supplied to the Burners
A pressure tap hole is located on the side of the
regulator to allow checking of the manifold pres-
sure. Remove the regulator plug and install a
WB02X10820 tap (or 1/8 in. NPT nipple) for test
with a manometer. Turn on the gas and light at least
one burner to serve as a load. Reinstall the regular
plug and check for leaks.
Optional Combination Installations
This cooktop may be installed in combination with a
ZVB36 Monogram downdraft vent, with a ZTD30
warming drawer, or with a ZET837 single convec-
tion oven. The gas and electrical supply must be
located where it will not interfere with the vent
housing, the oven, or the warming drawer.
