This appliance is factory
preset for propane/LP gas.
No changes are required for
connecting to propane/LP.
Only a qualified installer or service
technician can perform gas selec-
tion 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 plug.
WARNING: Do not attempt to
access or change the setting of
the fuel selection means.
1. The inlet regulator is color coded for iden-
tification of the correct gas type. Blue is for
propane (LP gas) and yellow is for natural
gas.
2. The inlet regulator requires a 3/8" NPT
threaded fitting. Apply a thread sealant
that is rated for use with the type of gas
that is being used.
3. Determine the type of gas that will be
used by the appliance. If your gas type is
Propane/LP remove the blue dust cover. If
your gas type is Natural gas remove plug
from natural gas inlet. Remove blue dust
cover from propane/LP inlet and install
plug. This will keep debris out of regulator.
Note: After the outside plug on the bottom
of the regulator has been removed, 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 to the gas being supplied.

been hand tightened into the regulator
use a wrench to complete tightening of
the fitting.
