Prior to applying power to the appliance its circulation pump should be bled and checked to ensure free rotation of the armature. Also ensure that the ignition electrodes spark gap is set to 4mm. 17.
© MHG Heating Ltd The output of the appliance can be altered by using the maximum outout and 0% minimum output. buttons to move between 100% Alterantaivley the output of the appliance can be altered by using the increase the output by 1% per press. buttons to descrease or This mode is maintained until the limit thermostat temperature is reached or the coommissioning buttons are pressed from more than 1 second.
© MHG Heating Ltd The combustion setting required for all ProCon appliances are as detailed in the following table. Gas Type Natural Gas (G20) LPG (G31) High Fire 8.5% C02 11.0% CO2 Low Fire 9.0% CO2 11.0% CO2 17.3 Conversion of the Appliance to Operate on LPG (G31). Unless specified at the time of ordering the appliance/s will be supplied ready to operate on a Natural Gas (G20) fuel supply. The appliances data badge will indicate the type of fuel gas the modules have been set to operate with.
© MHG Heating Ltd 18.0 Routine Inspection and Servicing.(A QAA73 Room Unit/service tool is required to reset the modules service interval timer.) As with all Gas Appliances, we would highly recommended that a competent heating engineer services the ProCon, at least every 12 months. This is assuming a normal daily usage of 8 – 10 hours. If however the boiler is to be operated 24 hours a day, 7 days, we would recommend services every 6 months.

If the heat exchanger has not suffered from dis-colouration, as ‘Item g’ above, then a Standard Service can be undertaken. Using a natural bristled brush ONLY, remove the worst of the mineral/debris build up.
