When using natural gas
as the fuel:
--- The regulator supplied with the dual fuel heater
is required for use with natural gas if the natural
gas supply pressure to the heater is above the
maximum inlet pressure of 13.5 in. W.C./3.36 kPa,
as stated on the heater's dataplate and in this
owner's manual.
--- The regulator requires a minimum natural gas sup-
ply pressure of 2 PSIG/13.8 kPa.
--- Remove the POL fitting assembly with hand-wheel
from the regulator inlet.
--- Connect the regulator to the natural gas supply
line using the proper connections.
