In an Emergency
If a water or gas leak occurs or is suspected, the boiler
can be isolated at the inlet valves as follows;
1. Turn off the electrical supply and turn the selector
switch on the facia box to the Off position.
2. Using a suitable open ended spanner or screwdriver
turn the square on the gas tap to the left to isolate the
gas supply at the boiler (Fig. 1).
3. The isolating valves are positioned under the boiler
and can be closed by turning their taps to the right
towards the wall (Fig. 2).

Introduction
1. Your Potterton Performa System HE is a gas fired,
room sealed, powered flue boiler, providing central
heating and hot water for your home. It is fully
automatic and does not have a pilot light.
2. Due to the high efficiency and resultant low flue
gas temperature when in condensing mode a white
plume of condensate will be emitted from the
terminal. This will be particularly evident during
periods of low outside temperature.

temperature control knob and pressure gauge, the
facia incorporates nine neon indicator lights.
2. Neons 10, 11 & 12 indicate the operational status
of the boiler. Neons 4 to 9 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.

(Fig. 5).
) will illuminate
4. On Position: In this position the boiler will provide
central heating or domestic hot water according to
demand (Fig. 7). The boiler on ( ) will illuminate

Temperature Control
1. The water flow temperature can be adjusted
between 30° C (± 5° C) minimum and 85° C
(± 5° C) maximum.
2. Turn the control knob clockwise to increase the
temperature (Fig. 8).
3. In normal winter usage we recommend that the
temperature be set at maximum.
Flame Failure Reset

Temperature Control
1. The red flame failure neon ( ) will illuminate in
the event of the burner failing to light, when
incomplete lighting of the burner occurs or blockage
of the condensate drain (Fig. 9).
2. Turn the selector switch fully anti-clockwise
against the spring pressure to the ‘Reset’ position for
at least two seconds and release (Fig. 10).
3. If the flame failure light illuminates repeatedly a
fault is indicated with the boiler, gas supply or
condensate drain. Your Installer or Service Engineer
should be contacted as soon as possible.

Air Flow Monitor
1. The boiler is fitted with an air pressure sensing
device. This monitors the flue system.
2. If the (
) neon illuminates it indicates that the
flue or flue terminal is blocked or obstructed in some
way, or that there is an internal fault. If there is no
external blockage of the flue terminal that can be
easily removed contact your Installer or Service
Engineer (Fig. 11).

Safety Thermostat
1. Your Potterton Performa System HE is fitted with
an additional safety devices, which shut down the
boiler in the event of the system, boiler or flue
overheating. The safety thermostat neon ( ) will
light in this instance (Fig. 11).
Fig. 12
2. To reset: Turn the selector fully anti-clockwise
against the spring pressure to the ‘Reset’ position for
at least two seconds and release (Fig. 12).
3. If after turning the selector to the ‘Reset’ position
the boiler does not relight or the safety thermostat
operates repeatedly, causing boiler shutdown, a fault
is indicated. Your Installer or Service Engineer should
be contacted as soon as possible.

Normal Pressure (operating)
1. The water pressure in the central heating system
is indicated by the pressure gauge.
2. With the system cold and the boiler not operating
the pressure should be between 0.2 and 1.0 bar.
During operation the pressure should not exceed 2.5
bar, and will normally be between 1.0 and 2.0 (Figs.
13 & 14).
3. A pressure of 3 or greater indicates a fault. The
safety pressure relief valve will operate, at a pressure
of 3 (Fig. 15). It is important that your Installer or
Service Engineer is contacted as soon as
possible.
4. The minimum pressure for correct operation is 0.2.
If the pressure falls below 0.2, this may indicate a
leak on the central heating system (Fig. 16).

*NOTE: The boiler can be operated with a clearance
of 5mm at the right. This is also sufficient for routine
maintenance. However a clearance of 20mm is
required if it is necessary to remove the secondary
heat exchanger. This should be considered when
siting the appliance and in the event of any
subsequent alteration in the area of installation.
780mm
2. These areas must not be obstructed in any way.
Blocking the clearance spaces may result in the
boiler overheating and damage may occur.
3. The gas burning compartment of your boiler is
completely sealed from the room in which it is fitted.
Products from the combustion of gas are vented to the
outside through the flue terminal which must be kept
free from obstruction as this would interfere with the
correct operation of the boiler.
4. The boiler may be installed in a cupboard if these
minimum clearances are kept. The compartment
should be large enough to house the boiler and
ancillary equipment only.
