Ensure that the gas inlet appliance isolating valve is in the “off” position.
2.
Press the power rocker switch, positioned on the front of the appliance next to the control thermostat, to

If the above occurs correctly, open the gas inlet appliance isolating valve and reset the unit by
depressing the button on both upper and lower control panels.

drain, pressure gauge etc. are in a serviceable and working condition and still comply with the relevant standards
and codes of practice, as detailed in the Installation, Commissioning and Maintenance Instructions.
