INSTALLATION - Electrical
The water heater is supplied with a 1,0 metre lead and plug and requires a permanent weatherproof 240 V 50 Hz general purpose outlet
(GPO) to be located within 1.2 metres of the installation. The GPO must be clear of the flue exhaust, draining water, gas supply pipe and water
connections. The water heater will only operate on a sine wave at 50 Hz. Devices generating a square wave cannot be used to supply power
to the water heater.
COMMISSIONING
All water heaters are tested and adjusted before dispatch from the factory, however further adjustments may become necessary because of
local conditions.
TO TURN ON THE WATER HEATER
Open all of the hot taps in the house (d
on’t forget the shower).
Open the cold water isolation valve fully at the inlet to the water heater. Air will be forced out of the taps.
Close each tap as water flows freely from it.
Check the pipe work for leaks.
Open the gas isolation valve fully.
Check the gas pipe work for leaks.
Plug in the water heater at the power outlet and switch on the electrical supply.
Turn on a controller, if one is fitted, by pressing the on / off button.
The light in the on/off button and the ACTIVE light (Deluxe controller) will both glow.
Open a hot tap.
The water heater will operate automatically.
Check to ensure the flow from each connected hot tap is sufficient to operate the water heater.
The minimum operating flow rate for all models is 2.5 litres per minute.
The automatic water governor incorporated in the water heater is not adjustable; water flow is automatically controlled by PCB
To complete the installation, it is necessary to check the gas supply pressure at the inlet to the water heater
GAS INLET PRESSURE
It is the Installers responsibility to check the gas meter, service regulator and pipe work 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.
IMPORTANT - CHECK (1);
The
static
gas supply pressure to be measured at the inlet to the water heater with the water heater and all
other gas burning appliances in the premises turned
OFF.
The minimum gas supply pressure must be:
Natural Gas 2.0kPa LPG 2.80kPa
If this minimum cannot be achieved, it may indicate the meter, gas supply line, gas cylinder/s or regulator to the
water heater is undersized. It is important to ensure that an adequate gas supply pressure is available to the
water heater.
IMPORTANT - CHECK (2);
The
operating
gas pressure to be measured at the inlet to the water heater with the water heater and all other
gas burning appliances in the premises turned
ON FULL
. The minimum gas supply pressure must be:
Natural Gas 1.20kPa LPG 2.75kPa
If this minimum cannot be achieved, it may indicate the meter, gas supply line, gas cylinder/s or regulator to the
water heater is undersized. It is important to ensure that an adequate gas supply pressure is available to the
water heater when other gas burning appliances on the same gas supply, are operating.
PLEASE NOTE: ALL PALOMA UNITS ARE CORRECTLY SET AND INDIVIDUALLY TESTED BY
THE MANUFACTURER. NO INTERNAL ADJUSTMENTS SHOULD BE MADE TO THE GAS
BURNER PRESSURES
