2.1 Introduction
1. Your Potterton Performa 28 is a gas fired,
room sealed, powered flue combination boiler,
providing central heating for your home and
mains fed domestic hot water to taps and
shower. It is fully automatic and does not have a
pilot light.
2. Priority is given to the hot water mode - when
a hot water tap is turned on the supply of heat to
the central heating circuit is interrupted.
2.2 Facia Panel
1. The facia panel is behind the hinged lower
door. As well as the on/off/reset selector switch,
temperature control knobs and pressure gauge,
the facia incorporates ten neon indicator lights.
2. Neons 12 to 15 indicate the operational status
of the boiler. Neons 6 to 11 have a dual function,
indicating the temperature of the central heating
water when constantly illuminated. If a fault
develops the appropriate neon will begin to
flash. Refer to Sections 3.3 to 3.7.
