LPG FUEL

It is strongly recommended that, on LPG installations, gas detection equipment is fitted. This equipment should be
positioned near the appliance and at low level. It is also important that the space housing the appliance is
adequately ventilated at high and low level. This appliance must not be located below ground e.g. in a cellar

In addition to those documents listed in Section 4.1: RELATED DOCUMENTS within the main body of the installer's guide the gas installation
should also comply with the guidance offered in the following documents.

This process must be carried out in the order stated when the water heater is switched on for the first time. Failure to follow the following
procedure may lead to non-warrantable damage to the water heater.
Before starting the conversion procedure the control parameter for gas type should be adjusted as below:
P4 BD Gas type (0=standard, 1=propane , 2=B/P) (display D8)
This parameter is set 0 for the common used gas types such as natural gas G20 or G25.
By setting this parameter 1 for propane G31, fan speed is reduced.
Set this parameter 2 for B/P. G30
0 = standard gas (e.g: natural gas)
1 = propane
2 = B/P
For each setting, the relevant Soft start settings are automatically adjusted, depending on its main setting P4BE, see section 15.4.
If this is a gas conversion, paste the corresponding sticker at the appropriate position in the Water heater and
mark the square for the used gas type. Also mark the square, indicating that the correct value has been set for
parameter P4BD.
Due to the design of the water heater, the conversion to LPG-Propane requires adjustment of the gas valve only (see 24.2.1). The sequence
is as follows:
1. Ensure that the gas inlet appliance isolating valve, provided by the installer, is in the "off" position.
2. Press the power rocker switch, positioned on the front of the appliance next to the control thermostat, to bring the equipment on.
3. Depress the recessed button located below the computer interface port to place the water heater into service mode.
4. The combustion fan should ramp up to full speed to purge the combustion chamber and then drop back to half rate in order to light.
The spark generator should create a spark, visible through the burner sight glass. As the gas inlet appliance isolating valve is closed,
the controls should go to a flame failure condition after four ignition attempts.
5. Isolate the electrical supply to the appliance. Turn screw 2 clockwise until the screw stops then turn anti-clockwise through two full
turns.
6. Turn on the main power to the water heater, press the reset button and place the unit into service mode.
7. If the water heater does not fire after three ignition attempts, turn screw 2 through a further half turn anti-clockwise.
8. Turn the set point dial fully clockwise, this should ramp the fan up to its maximum speed.
9. Adjust screw 2 to give a CO

10. Turn the set point dial fully anti-clockwise, this should ramp the fan down to its minimum speed.
