Form#7.2-70 Issue#2
Do not attempt to locate leaks by using an open flame. Repair and re-test the system
before putting it into operation.
For more detailed general instructions on the installation of Propane systems on boats,
please refer to the American Boat and Yacht Council’s pamphlets #A-1 and #A-22
respectively. These pamphlets may be ordered directly from A.B.Y.C.
OPERATING INSTRUCTIONS
1. The first time you use your heater you will have to purge the air out of the supply
lines before it will light. Turn the knob to the “pilot” position and push in. You
may hear a hissing sound. Keep the knob pushed in until you smell gas, then
immediately turn the knob to the “OFF” position. Wait a few moments before
lighting to allow any excess propane to dissipate. Purging air can take quite a
while if you have a long supply line. This is only necessary when fuel supply is
disconnected.
2. Do not forget to remove any plastic before using.
3. Push control knob in, hold it in and turn counter-clockwise to pilot position. If this
is the first time or the first time in a while that the heater is being used, push in the
knob on the pilot setting for 60 second or until you smell gas. This will purge the
pilot light parts of air. Then, with the knob depressed on pilot, push in the black
spark-ignition button to ignite pilot. Once ignited, hold control knob in for 10 to
20 seconds. If it does not light, repeat this procedure. If it still does not light,
purge the line some more or hold match over pilot.
4. When the oxygen depletion pilot flame comes on, you must hold the knob in for
10 to 20 seconds. During this time the pilot flame heats up the thermocouple.
When the thermocouple is hot it generates a small amount of voltage, which will
energize a small solenoid coil inside the gas valve. This energized coil permits the
valve to regulate propane into the burner.
5. Adjust the burner by turning counter-clockwise to Low. To extinguish, turn the
knob all the way clockwise to Off.
Caution: This heater consumes oxygen. You must supply sufficient outside
air to replace the oxygen used by the heater. This unit is equipped with an
oxygen depletion device which will turn off the pilot flame when the oxygen
level drops to 95% of normal. This, in turn, cools off the thermocouple,
which shuts off the main valve.
