3.4 ELECTRICAL CONNECTION
The boiler is supplied with a standard 10 amp 3 pin plug for connection to a 240V 10 amp earthed GPO. The
boiler incorporates a 240/24 VAC transformer which supplies power to the control circuit only and must not be
used for any additional equipment. All equipment connected to mains power should be protected by an RCD
circuit breaker. The boiler has a 240 volt power supply for the pump electrical connection which incorporates the
pump run on feature. A terminal strip is provided for a 24 volt room thermostat.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a suitably qualified
person in order to avoid a hazard.
If the Hurlcon Genus IV central heating thermostat is used the 24volt room thermostat connection must be bridged.
Also unplug the spade connector from terminal IN-1 on the small heatsaver PC board in the electrical box and
make safe. This is the middle terminal on the top side. See page 16.
3.4.1 GAS CONNECTION
A ¾”BSP FI is provided for gas line connection. An approved manual shut off valve must be installed in the gas
fitting line before the boiler so that the gas can be turned off and the boiler removed for servicing if required. The
gas shut off valve should be sized the same as the gas fitting line to prevent excessive pressure drop in the gas
pipe.
The gas fitting line should be installed by an authorised person and comply with local regulations and A.G.A. code
AGS5601. The gas line from the meter will usually be of a larger size than the gas inlet connection. Therefore a
reduction to the boiler connection fitting will be necessary. The reduction should be as close to the boiler as
possible.
Before using the boiler, test all connections for gas leaks using soapy water.
The boiler gas valve has a built in pressure regulator with a
⅛” pressure test point provided. On starting the boiler,
a manometer must be used and burner pressure checked against the boiler data plate. The gas valve regulator
may need adjustment to correct manifold pressure. Incorrect burner pressure may void warranty.
