Conversion To/From Lp (Propane) Gas - GE Monogram ZGU375NS Technical Service Manual

Conversion to/from LP (Propane) Gas

Before you begin, read these instructions completely and carefully
WARNING
This conversion kit must be installed by a qualified service
agency in accordance with the manufacturer's instructions
and all applicable codes and requirements of the authority
having jurisdiction. If the information in these instructions
is not followed exactly, a fire, explosion or production of
carbon monoxide may result, causing property damage,
personal injury or loss of life. The qualified service agency
is responsible for the proper installation of this kit. The
installation is not proper and complete until the operation
of the converted appliance is checked as specified in the
manufacturer's instructions supplied with the kit.
PROCEDURE
CAUTION:
Before proceeding with the conversion, shut off
gas supply to the appliance prior to disconnecting the
electrical power.
The following steps must be followed to ensure the proper
conversion of the Monogram Sealed Burner Cooktops from
Natural Gas (NAT) to Liquid Propane Gas (LP) or Liquid
Propane to Natural:
STEP 1
Gas Supply
Measure the incoming gas pressure to the regulator.
With the installation of this conversion kit, the cooktop should
operate on LP gas at 10" of water column pressure and
on natural gas at 4" of water column pressure.
• The pressure regulator must be connected in series with the
manifold of the cooktop and must remain in series with the
supply line.
• When checking the regulator, the inlet pressure must be at
least 1" greater than the regulator output setting.
– If the regulator is set for 10" of water column pressure, the
inlet pressure must be at least 11".
For proper operation, the maximum inlet pressure to the
regulator must be no more than 14" of water column pressure
for LP gas.

piping system during any pressure
testing of that system at test
pressures greater than 1/2 psig.
Isolate the cooktop from the gas
supply piping system by closing
the individual manual shutoff
valve to the cooktop during any
pressure testing of the gas supply
piping system at test pressures
equal to or less than 1/2 psig.
