OPERATION
IMPORTANT
Only qualied personnel shall perform the initial ring of the heater.
At this time the user should not hesitate to ask the start-up technician
any questions regarding operation and maintenance of the unit.
Lighting and Operating instructions are included with this manual.
By using these instructions, the user may be able to make minor
operational adjustments and save unnecessary service calls.
However the user should not attempt repairs, but should contact
a service technician or gas supplier.
GENERAL
Never operate the water heater without rst making sure the water
heater and system are lled with water, in addition:
• Make sure a temperature and pressure relief valve is installed
at the water heater and if used, the storage tank. Also check
for leaks.
• Also be sure to check the gas piping for leaks before beginning
the initial ring of the heater.
FILLING
1. Close the systems drain valve by turning handle clockwise.
2. Open a nearby hot water faucet to permit the air in the system
to escape.
3. Fully open the cold water inlet pipe valve allowing the heater
and piping to be lled.
4. Close the hot water faucet as water starts to ow.
5. The heater is ready to be operated.
GAS LINE LEAK TESTING
Fire and Explosion Hazard
Leak test before placing the water
heater in operation.
Disconnect gas piping and main gas
shutoff valve before leak testing.
Install sediment trap in accordance
with NFPA 54.
Use joint compound or Teflon tape
compatible with propane gas.
Any time work is done on the gas supply system perform a leak test
to avoid the possibility of re or explosion.
1. For test pressures exceeding 1/2 psi (3.45 kPa) disconnect the
water heater and its Main Gas Shutoff Valve from the gas supply
piping system during testing, see Figure 21. The gas supply line
must be capped when disconnected from the water heater.
2. For test pressures of 1/2 psi (3.45 kpa) or less, the appliance need
not be disconnected, but must be isolated from the supply gas line
by closing the Main Gas Shutoff Valve during testing.
3. Coat all supply gas line joints and connections upstream of the
water heater with a non-corrosive soap and water solution to
test for leaks. Bubbles indicate a gas leak. Do not use matches,
candles, ame or other sources of ignition for this purpose.
4. Repair any leaks before placing the water heater in operation.
PURGING
Gas line purging is required with new piping or systems in which air
has entered.
Purging should be performed per the current edition of NFPA 54 the
National Fuel Gas Code.
CAUTION
BEFORE PROCEEDING WITH THE OPERATION OF THE
UNIT, MAKE SURE HEATER AND SYSTEM ARE FILLED
WITH WATER AND ALL AIR IS EXPELLED FROM HEATER
AND PIPING.
THE MAIN MANUAL GAS SHUTOFF VALVE AND THE PILOT
ADJUSTING VALVE (WHEN APPLICABLE) MUST HAVE BEEN
CLOSED FOR AT LEAST FIVE (5) MINUTES. THIS WAITING
PERIOD IS AN IMPORTANT SAFETY STEP. ITS PURPOSE
IS TO PERMIT GAS THAT MIGHT HAVE ACCUMULATED
IN THE COMBUSTION CHAMBER TO CLEAR. IF YOU
DETECT GAS AT THE END OF THIS PERIOD, DO NOT
PROCEED WITH LIGHTING. RECOGNIZE THAT GAS ODOR,
EVEN IF IT SEEMS WEAK MAY INDICATE PRESENCE OF
ACCUMULATED GAS SOMEPLACE IN THE AREA WITH A
RISK OF FIRE OR EXPLOSION. SEE THE FRONT PAGE
FOR STEPS TO BE TAKEN.
DO NOT USE THIS HEATER IF ANY PART HAS BEEN UNDER
WATER. IMMEDIATELY CALL A QUALIFIED SERVICE
TECHNICIAN TO INSPECT THE HEATER AND TO REPLACE
ANY PART OF THE CONTROL SYSTEM AND ANY GAS
CONTROL WHICH HAS BEEN UNDER WATER.
Light the unit in accordance with the instructions on the lighting
label attached to the water heater. These instructions are
repeated in the following.
