Davey POOL AND SPA GAS HEATERS - Manual (Page 6)

Part No: 96131430D 6 Rev: 2
GAS SUPPLY
The gas supply pipe and gas meter must be sized so that both are capable of providing sufficient gas for all gas appliances on the
site to operate at the same time. Insufficient gas supply will cause the heater to operate below its designed performance or not at
all.
Correct pipe sizing for the gas fitting line should be obtained from AS5601. During commissioning of the heater the burner
pressure must be adjusted by the gas fitter to conform to the specifications provided on the Davey Dataplate - located inside the
heater. The heater and its gas line must be fully leak-tested prior to normal operation.
Note: It is more important than ever that when installing a new gas pool or spa heater, the commissioning must be carried out by a
licensed plumber . Gas supply companies are increasingly supplying natural gas to new installations with 2.75Kpa. This means if
the gas pressure is not adjusted to the correct working pressure (see data plate) the heater will be over gassed and cause serious
damage within minutes. This damage is not covered under the Warranty.
Caution! Excessive Gas Pressure will damage the gas valve and void warranty.
