INSTALLATION
Only For Qualified Installers
Burn Only the Fuel for which the Heater is
Equipped
The Serenity III Direct Vent will burn either natural gas
or propane, but requires a change over kit for propane.
The label on the burner system module indicates the fuel
for which it is equipped. A second label, (on the valve)
also indicates the fuel type.
Making The Gas Connection
The gas inlet is located on the bottom right side of the
fireplace. The inlet fitting is a 3/8” female flare flexible
pipe.
A separate gas shut-off valve and a 1/8” N.P.T. plugged
tapping should be installed immediately upstream of the
connection to the appliance.
The Serenity III Direct Vent Gas Heater must be
disconnected from the gas supply piping during any
pressure testing of that system at pressures in excess of
1/2 psig (3.5 kPa).
The Serenity III gas control valve must be in the OFF
position during any pressure testing of the gas supply
system at pressures equal to or less than 1/2 psig (3.5
kPa).
WARNING: This product must be installed by a
licensed plumber or gas fitter when installed within
the Commonwealth of Massachusetts.
WARNING: To avoid pipe compounds from entering
into the gas train, apply compounds only to male
pipe threads and do not apply compound to the first
two threads.
CAUTION:
TEST ALL JOINTS FOR LEAKS
BEFORE OPERATING.
Gas Pressure Requirements:
Correct gas pressure and the use of a properly sized
gas supply line are essential for the safe and efficient
performance of this appliance. Make sure that the
plumber or gas supplier checks the gas supply line and
gas pressure at installation.
NOTE:
Improper gas pressure can affect heater
performance, flame color, or cause pilot outage.
