Testing

1.Purge gas, hot water and cold water supply lines before making the final connection of the water heater. Swarf in either the gas or water supplies may cause damage.

2.Turn on gas and cold water supplies.

3.Test for water leaks and gas escapes near the unit.

4.Isolate gas and electric supply. Remove test point screw located on the inlet gas valve connection inside the heater and attach pressure gauge.

5.Turn the power on at the switch and turn on gas. Warning: There are 230V AC live supplies inside the heater.

6.If remote controllers are fitted, turn the controller on, select the maximum delivery temperature and open ALL available hot water outlets. If remote controllers are not fitted, simply open all available hot water outlets. (CAUTION: Ensure building occupants do not have access to hot water outlets during this procedure).

7.The gas pressure check must be carried out with all other appliances on the same main operating at maximum capacity to ensure that there is sufficient gas pressure.

8.With all other appliances operating the pressure at the test point on the inlet to the gas valve should read 20 mbar for Natural Gas. For LPG (Propane) the pressure should be 37 mbar. If the pressure is lower, the gas supply is inadequate and the water heater will not operate to specification. Check gas meter, regulator and pipework for correct operation/sizing and rectify as required. Note that the gas regulator on the appliance is electronically controlled and factory pre-set. Under normal circumstances it does not need adjustment during installation.

9.Close hot water outlets.

10.Inspect and clean the strainer and the filter located on the cold water inlet pipe. This procedure may need to be repeated to ensure the strainer remains clear.

11.If temperature controllers are fitted, it is necessary to test their operation through the complete range of functions.

12.Confirm the hot water delivery temperature using a thermometer. If controllers are fitted, compare the measured value to the set point.

13.After testing is completed, explain to the user the functions and operation of the water heater and temperature controllers.
