that any servicing must be carried out by a competent person. Removal of the appliance
cabinet by anyone other than a competent person will automatically invalidate the
appliance warranty.

BOILER SETUP & OPERATION
Check that the gas supply from the gas meter is turned on. Switch on the electrical supply to
the boiler. The display will now run through a self check procedure. Set any controls to call for
heat.
To light the boiler
The Q37 features separate two temperature controls to allow different settings depending on
the source of the demand, i.e. heating or hot water. To set these press the “+” or “-” buttons
associated with the 1st stat or 2nd stat temperature and set the required temperature. After a
few seconds the display stop flashing and will change back to show the actual boiler

is less than the desired
temperature the boiler will

corner of the display to
