1. Remove protective cap from POL fi tting. Do not
discard cap. Position regulator as shown to protect
its vent, or install protective cover over the regulator
and cylinder valve.
2. Insert POL fi tting into propane supply valve. See
Fig.5. Thread nut on fi tting counterclockwise into
propane supply valve. Tighten nut securely with a
wrench.
-- When storing or transporting the heater, ensure the
cap is pushed onto the POL fi tting to prevent dam-

-- Connect the appropriate gas supply line to the inlet
of the regulator located on the heater. See Fig. 6.
This regulator takes an inlet pressure of 13.5 In.W.C.
(3.36 kPa) maximum or a minimum inlet pressure of
7.0 inches W.C. (1.74 kPa) The regulator reduces
the inlet pressure down to 5.1 In. W.C. (1.27 kPa)
for operation.
For inlet pressures exceeding 13.5 In.
W.C. (3.36 kPa), an additional regulator
will be needed upstream of the heater's
regulator to reduce the higher pressure to
the required inlet pressure.
