2.0 Operating the Boiler
4
2.1 Operating the Boiler
1. Turn on the main gas and electricity supplies
to the appliance.
2. Switch the on/off switch on (Fig. 1).
4. The fan will start to run and after a short period
the ignition spark will commence. Sparking will
continue until the flame is established then stop
automatically. Check that a flame is visible
through the sight glass.
2.2 To shut down the Boiler
1. Turn off the electricity supply to the appliance
at the mains.
2. Press the on/off switch off (Fig. 1), then turn off
the gas supply at either the appliance gas cock
or the meter.
2.3 Frost Protection
1. The boiler does not have integral frost
protection. It is recommended that the installer
fits a suitable protection device to the system
controls if required. For frost protection the boiler
must be turned on.
2.4 In Operation
1. The Potterton Promax 15 HE and 24 HE are
high efficiency condensing boilers. In common
with other condensing boilers its exceptional
efficiency means the flue gases are cooled to
such an extent that steam is often visible at the
outside flue terminal. The amount produced
depends on system design, product use and
outside air temperature but it is not harmful to the
individual or the working of the appliance in any
way.

3.1 Operation of Safety Devices
1. Your Potterton Promax 15 HE or 24 HE is fitted
with safety devices which shut down the
appliance if:
a) the system overheats.
b) the condensate drain is blocked.
c) there is no gas to the boiler.
2. If your radiators and hot water are both cold
despite the programmer and room thermostat
being on, then one of these safety devices may
have operated and the boiler may need resetting.
NOTE: In the case of persistent operation of
the devices, turn off the boiler and consult your
service engineer as an appliance or system
fault is indicated.
3.2 Resetting
1. Allow the boiler to cool if hot.
2. Check that the gas supply to the appliance has
not been inadvertantly turned off.
