This appliance is factory
preset for propane gas. No
changes are required for
connecting to propane. Only a
qualified installer or service techni-
cian can perform gas selection and
connecting to gas supply.
CAUTION: Two gas line in-
stallations at the same time are
prohibited.
CAUTION: To avoid gas leak-
age for the gas not being used at
the inlet of regulator, a qualified
installer or service technician
must use supplied cap.
You will notice a color coded
plunger on the inside of the
regulator. This is normal. When
the inlet connection fitting is
inserted and tightened, this
plunger will be pushed back
by the fitting making all of the
adjustments for the gas being
supplied. DO NOT REMOVE THE
PLUNGER. The regulator will
not work and the warranty will
be voided.
The inlet regulator is color coded
for identification of the correct
gas type. Blue is for propane (LP
gas) and yellow is for natural gas.
