OPERATING THE WATER HEATER

FOR YOUR SAFETY READ BEFORE LIGHTING

TO FILL THE WATER HEATER

Water Heating Applications

•Open all of the hot water tap(s) in the building (don’t forget the showers) and supply cock(s) and valve(s) in the system.

•Open the isolation valves fully on the cold, flow / return and hot water branches to the storage tank(s) installed in a bank.

•Open the cold water isolation valve on the cold water line to the storage tank(s). Air will be forced out of the taps.

•Close each tap as water flows freely from it.

•Check the pipe work for leaks.

Mechanical/Process Heating Applications

•If a header tank is fitted, ensure it is filled with water.

•Open the isolation valve on the inlet line to the water heater.

•Bleed air from the system at all high points to ensure that the entire system is filled with water.

•Check the pipe work for leaks.

TO TURN ON THE WATER HEATER

WARNING! If you smell gas do not attempt to turn on the water heater.

The power supply to the water heater must not be switched on until the system is filled with water.

•Fill the system with water (refer to “To Fill the Water Heater” on page 32)

•Open the gas isolation valve fully at the inlet to the water heater.

•Plug in the power supply cord at the power outlet.

•Switch on the electrical supply at the power outlet to the water heater.

NOTE: If the water heater is correctly installed, this will also activate the circulating pump.

The water heater will operate automatically when a call for heat occurs.

TO TURN OFF THE WATER HEATER

If it is necessary to turn off the water heater on completion of the installation, such as on a building site or where the premises is vacant, then:

•Switch off the electrical supply at the power outlet to the water heater

NOTE: If the water heater is correctly installed, this will also shut down the circulating pump.

•Close the gas isolation valve at the inlet to the water heater.

•Close the cold water isolation valve at the inlet to the water heater.

•Close the isolation valves on the cold and hot water branches to shut down an individual water heater in a bank (water heating applications only).

TO RESET THE WATER HEATER

If the system water temperature is abnormally low, the ignition system may have locked out. The ignition system can be reset as follows:

•Turn the power to the water heater off.

•Wait five (5) minutes.

•Turn the power to the water heater on.

If the water heater still fails to operate, call your nearest Rheem Service Department or Accredited Service Agent to arrange for an inspection.
