II. General Operating Instructions
A. Lighting lnstructions
Gas and Electric
-
Read all safety information first. Turn gas cock clockwise to "OFF" position and
temperature indicator to the lowest setting. Turn off all electric power to the appliance. Wait 5
minutes for gas to clear the area. Turn gas cock counterclockwise to "pilot" position, press reset
button and light pilot, hold down until pilot remains lit. Turn gas cock counterclockwise to "ON"
position. If pilot goes out, repeat above procedure. On initial start-up, this may take several times
to purge the air from gas lines. Turn on all electrical power if combination electriclgas, and set
temperature dial to desired setting.
Gas and Electric With Reianitor
-
Place reignitor control in "OFF position. Turn gas cock clockwise
to "OFF" position, and temperature indicator to lowest setting. Turn off all electric power to appliance
and wait 5 minutes for gas to clear. Turn gas supply and electrical power to appliance on. Turn gas
cock counterclockwise to "pilot" position, press reset button and switch the electric reignitor module
to "ON" position. Spark will start between electrode tip and pilot hood. When pilot lights, the spark
will stop. Continue depressing reset button for approximately 1 minute or until light remains lit. On
initial start-up, it may take several times to purge air from lines. Turn gas cock counterclockwise to
"ON" position and set temperature dial to desired location.
When reignitor switch is in the "ON" position, it will operate automatically when the pilot flame is
extinguished. When the vehicle is to be stored or the LP supply is to be turned off, be sure to turn the
reignitor control switch to the "OFF" position. This will prevent the battery from being discharged (the
reignitor will continue sparking). The reignitor has an alarm that will sound when the pilot is
extinguished or the LP supply is turned off.
Direct Spark lunition
-
Read all safety information provided. Turn off all electrical power to the
appliance. Turn off gas supply and wait 5 minutes for gas to clear the area. Turn on gas and
electrical supply to the appliance. Turn switch to "ON" position, there will be a 15-second purge
before spark. If lockout occurs before main burner lights, turn switch to "OFF" position, wait 5
seconds and turn switch to "ON" position. This will restart the ignition cycle again. On the initial start-
up, it may require several ignition cycles to purge all the air from the gas lines.
B. VoltagelGas Pressure Requirements
The DSI water heater must have an acceptable DC-voltage range to function properly. An adequate
voltage range would be between 10.5 volts DC and 13.5 volts. This voltage must be supplied directly
from the battery or from the power converter wired in parallel with the battery.
The LP system working pressure should be 11" of water column (WC). When testing the pressure
of the system, at least'one other gas appliance needs to be in full operation to get accurate results.
Check pressure with manometer at unit and pressure coming through orifice to get correct reading.
Adjust accordingly. Do not overfill the propane tanks. The minimum working pressure is 11" WC,
while the maximum is 14" WC.
C. Safety
-
Gas Leak Check
A leak in the LP gas system is a critical area that involves checking for and then repairing the leak.
Most leaks occur when the system is open for service and improperly resealed, when LP tanks are
filled, or when appliances are installed. One way to check for leaks is to use a pressure gauge and
simply pressurize the system and turn off the gas valve. If pressure drops, find the leak and correct
it. A liquid leak solution can be applied to any fitting that was opened. Do not use a soap solution
with ammonia, as it is corrosive to brass. Also the electronic gas sniffer is a must for finding leaks in
hard-to-reach pla.ces.
