About the Boiler
•This is a Floor Mounted, Fan Assisted Balanced Flue
Gas Boiler. This boiler is for use with Natural Gas (G20)
only at 20 mbar and for use in GB/IE only.
•The information given in these instructions will help you
obtain the maximum comfort from your boiler with the
minimum trouble and cost. Please take time to read
through these instructions as they will help you
understand how to get the best use out of the boiler.
•Powermax HE is a condensing combination boiler in
which the gas burner heats the contents of the built-in
hot water store to provide domestic hot water. A pre-
mixed burner is used to ensure that the gas is burned
cleanly and efficiently.
•To reduce running costs, timed operation of the central
heating is essential and a Powermax programmer is
built-in to provide this function. It enables both hot water
and heating periods to be timed for both comfort and
economy. Your installer may have fitted another make
of programmer remote from the boiler and should have
provided you with instructions on its use.

Lighting
Check that the mains electricity and gas supply are both
turned ON. The amber neon on the control will light
when electricity is being supplied. Set the boiler On/Off
Switch to 'I' (ON), the boiler is now operational.
If the programmer is set to an ON period for Hot Water
the green 'burner' neon will light to indicate that the
burner has ignited and is heating the water (unless the
pre-set hot water temperature has already been
reached).
If the programmer is set to an ON period for Central
Heating the green 'burner' neon will light to indicate that
the burner has ignited and is heating the radiators
(unless the pre-set hot water store temperature has not
been reached or the system thermostat is not calling for
heat).
If the burner fails to light, the ignition sequence will be
automatically repeated until either the burner lights or a
safety Lock-Out condition is signalled by the red neon.
If the red neon lights note the error display code,see
Page 7. If appropriate, press the reset button on the
control panel and the boiler will re-set itself.
Operating Hints
When the burner is heating the water, the approximate
flow temperature can be indicated in the status display
window by a 't' for Hot Water or 'c' for Central Heating.
The temperature of the Hot Water can be adjusted by
turning the Temperature Control knob on the control
panel. The control temperature of this knob ranges
approximately from 45 °C to 65 °C. We recommend a
setting of 55 °C for normal operation.
During the summer period you can turn the Central
Heating off at the programmer. The life of the Central
Heating pump will be prolonged if you switch the Central
Heating on for a few minutes or so each week during the
summer period. Note: The boiler control will operate the
pump for a few seconds every day.
To turn the boiler off for short periods - set the central
heating and hot water channels to the OFF position at
the programmer. This leaves the boiler's built in frost
protection operational. To turn the boiler off for long
periods - set the boiler On/Off switch to the 'O' (OFF)
position and isolate the gas supply at the boiler. It may
be advisable to contact your Service Engineer if you
wish to do this.
How your boiler Works
Control of the Boiler
The boiler is fitted with a control panel which indicates
basic functions and also contains a programmer. If your
installer has fitted another make of programmer remote
from the boiler, the programmer display on the control
panel will operate as a clock only.
The burner automatically adjusts its heat output to meet
the demand of your central heating or hot water.
Central Heating
Your new Powermax HE works as part of a ‘sealed’;
pressurised hot water system which is why the boiler
has a pressure gauge and a means of re-filling the
central heating circuit.
Constant pressure in the pipework will find old or badly
made joints and allow water to weep or leak through.
Your installer should have advised you of this possibility
and recommended a course of action. It is not a fault of
the boiler.
Hot Water
To ensure a plentiful supply of hot water the Powermax
HE has a built in water store which during timed 'On'
periods is maintained around the selected temperature.
Your hot water taps may also leak due to the pressure
increase.
Hot water always takes priority over central heating
during a timed 'On' period. Where a significant volume
of hot water is drawn off (e.g. a bath) whilst the central
heating is on, the boiler will temporarily shut down the
heating until the required store temperature is restored
(this will typically take only 10 to 15 minutes).
Optional Immersion Heater
The hot water storage cylinder in your Powermax HE
may have been fitted with the optional electric
immersion heater. This is of a special type fitted with a
safety cut-out which switches off the heater in an
overheat situation. It is not interchangeable with
standard immersion heaters. Should it fail, use only a
genuine Powermax or Heatrae 'Mega' replacement
(Part No. P3223/5106143) which must be fitted by a
competent person.
A thermostat setting of around '3' (approx. 55 °C) is
recommended in hard water areas. Should the overheat
cut-out operate, it can be manually reset by pressing the
red button at the side of the thermostat dial. ALWAYS
investigate the cause of overheating before resetting.

Publication No. 5106228

Things you need to be aware of
Air Locks
The boiler pump is fitted with an automatic air vent and
will bleed air from the boiler when required.
To access the bleed screw for this vent, pull off the top
front cover, remove the small inner panel and the
screw cap is situated just below the opening. Unscrew
by no more than one turn when air in the system is
suspected. e.g. after replacing a radiator. Tighten
screw again after 24 hours.
C.H. System Pressure
The Status Display window shows the actual water
pressure in the central heating system. It will drop
slightly when the central heating starts and will rise by
anything up to 1.5 bar as the central heating reaches
full temperature.
We recommend that the system pressure, when cold
be between 1.0 and 1.5 bar. If the pressure is falling,
the status display will flash ‘P 0.9’or lower and it is
advised to top up at this stage. If the pressure drops
below 0.5 bar the boiler will not light, the status display
will show ‘P 0.4’or 'A 15’and it will be necessary to
top up the pressure.
To top up: Pull bottom panel off front of boiler and
connect filling loop to valve on cold water inlet. Open
both valves slowly and allow pressure to rise. Close
valves, disconnect filling loop and re-fit bottom panel.
If regular topping up is needed get your installer to
check the system for leaks.
Severe loss of system pressure is indicated by 'A 15'
on the display and the red 'Lockout' neon will be on.
Top up as above then press the ‘Reset’button, this will
reset the boiler and it should now light.
Flue
This exits through the roof or outside wall. Ensure it
does not become obstructed, particularly by foliage or
snow. Due to the high efficiency of the boiler and the
resulting low flue gas temperature, a plume of white
condensate may be emitted from the flue outlet
terminal. This will be particularly noticeable during cold
weather and does not indicate a problem with the
boiler.
The flue pipe becomes very hot when the boiler is
operating. If the pipe is visible (such as in a loft space)
it is important that no flammable materials are allowed
to come into contact with the pipe.
Freezing Conditions
If the water temperature within the boiler drops below
5 °C, a sensor operates and runs the burner to keep
the water from freezing. This will only operate if the
electricity supply to the boiler is ON. If you are away
during periods of cold weather we recommend leaving
your boiler on and adjusting your control system (e.g
thermostat) to suit.
Condensate Outlet Pipe
If this has been run externally, it may drip water. This is
perfectly normal. Steps should be taken to prevent the
outlet freezing in very cold weather.
Safety Discharge Pipe
Ask your installer to identify the discharge pipe from
the pressure relief valve. Normally no water is vented
but scalding water and steam may be emitted and
indicate a fault condition. Switch off the boiler and call
your Installer.
Precautions should be taken to prevent the outlet
becoming blocked and to minimise the hazard to
persons (especially children) where the pipe
discharges.
Cleaning
The outer case parts can be wiped down with a damp
cloth to remove any marks. Do not use abrasive
cleaning agents as they may damage the finish on the
case parts.
Other controls
These may be fitted within the system e.g. room
thermostat. Full instructions on their use should have
been supplied with them.
In an Emergency
Gas - In the event of a gas leak turn off the supply at
the isolating cock. If the leak is in the pipe from the gas
meter then turn off the isolating cock at the meter as
well. Call your gas supplier immediately.
Electricity - The boiler can be isolated from the mains
supply by removing the plug from the socket or
switching the fused supply off.
Central Heating system - If a radiator, pipe or the
boiler starts leaking, set the boiler On/Off Switch to
‘Off’as this will stop the pump from working and will
minimise loss of water. Reference can be made to the
Installation & Servicing Instructions on how to remove
the outer casing and close the isolating cocks to the
central heating flow and return.
Hot Water - If a hot water pipe starts to leak, set the
boiler On/Off Switch to ‘Off’, turn off the mains water
supply at the stopcock and collect the water in a
suitable container, take care, it could be Very Hot.
(Remember to switch on any supplies you have closed once the
problem has been corrected).

How to set the Programmer
This section is relevant only if your programmer has
been enabled. Refer to 'Programmer not working' on
Page 7 if unsure.
Using the Powermax programmer, you can set your
Hot Water and/or Central Heating to come on for three
time periods per day, with different or common times
for Hot Water and Central Heating.
It does take time for the boiler to produce the required
temperatures, so set the programmer to switch on, for
example, 30 minutes earlier than you will require
Central Heating and around 20 minutes earlier than
that to allow the Hot Water store to heat up.
Other controls in your system (such as a room
thermostat) may affect the switching of your boiler. So
although the indicator shows that the central heating is
on, the boiler itself could be off.
(Ask your installer how they work).
Setting the Programmer for Built-in Times
The programmer already has built-in time periods,
which are shown below (represented as a 12 hour
clock).
Central Heating - Monday to Friday
ON1 OFF1 ON2 OFF2 ON3 OFF3
07.00 09.30 12.00 12.00 5.00 11.00

changes have been made to them, firstly ensure the
programmer is in Normal Operation (Section 1.0, Page
6). Then press & hold down the + and - buttons
together, after 2 seconds or so, release the two
buttons and the built in periods will be active.
Using the HW and CH 'SELECT' Button
During normal operation, by pressing these buttons
you can select how you wish your system to work:
OFF When selected, the boiler will stay
turned off.
TIMED Allows the Central Heating and/or Hot
Water to run to the times you have set in
the programmer’s memory.
ONCE Allows your Central Heating and/or Hot
Water to run once a day, from the first
ON time to the last OFF time.
ON Will turn the Central Heating and/or Hot
Water on continuously 24 hours a day.
Using the 'ADVANCE' Button
The ADVANCE button allows you to go forward to the
next ON or OFF time for Central Heating only, when
timed is selected. To advance the programme, simply
press the ADVANCE button and the Central Heating
neon will go OFF (if on) or ON (if off), press again to
return to original setting.
Programmer Memory Backup
If the electricity fails or is switched off, the display will
go blank, but the programmer will maintain the set
times and the clock for 12 hours. When the power
comes back on, you may have to reset the clock and
switch times.
Note: During the time that the electricity is off, any
electrical items, e.g. Boiler, pumps, etc. will not
operate.
If the programmer battery fails, a replacement (Part
No. 5106294) is available. Always dispose of the old
battery in a safe manner.
