Introduction
The IMAX XTRA boilers are fully automatically controlled, oor
standing, fanned, super efcient condensing appliances.
Due to the very high efciency, condensate is produced from the
ue gases and this is drained to a suitable disposal point through
the plastic waste pipe at the bottom of the boiler. A condensate
'plume' will also often be visible at the ue terminal.
Safety
Current Gas Safety (Installation & Use)
Regulations or rules in force.
In your own interest, and that of safety, it is the law that this boiler
must be installed and maintained by a CORGI registered installer
or in IE a competent person, in accordance with the above
regulations.
The appliance should be serviced at least once a year by a
CORGI registered installer or in IE a competent person.
It is essential that the instructions in this booklet are strictly
followed, for safe and economical operation of the boiler.
Electricity Supply
The appliance must be earthed.
Supply 230 V - 50 Hz. The fusing should be 5A for E80 & E120
and 7A for E160-E280.
This appliance is intended to be connected to the supply via a
double-pole switch, having a 3mm contact separation in both
poles, serving only the boiler and system controls. Alternatively, a
3-pin UNSWITCHED socket may be used.
Important Notes
• This appliance must not be operated without
the casing correctly tted and forming an adequate seal.
• Do not store objects around or on the boiler, and keep access
clear at all times.
• Do not obstruct ventilation ducts, grilles or openings in the
boiler room, room space or compartment that the appliance is
installed in, or the passage of combustion and ventilation to
the boiler.
• Do not turn off the boiler if it is to be left unattended in frosty
weather.
• If it is known or suspected that a fault exists on the boiler then
it MUST NOT BE USED until the fault has been corrected by a
CORGI registered installer or in IE a competent person.
• Flammable materials must not be placed in close proximity to
the appliance. Materials giving off ammable vapours must not
be stored in the same room as the appliance.
In cases of repeated or continuous shutdown a CORGI registered
installer or in IE a competent person should be called to
investigate and rectify the condition causing this and carry out an
operational test after each intervention on the device. Only the
manufacturers original parts should be used for replacement.

To light the boiler (Refer to Frame 1)
1. CHECK THAT THE ELECTRICITY SUPPLY TO THE BOILER
IS OFF.
2. Set the burner on/off switch (A) to off.
3. Switch on the electricity supply to the boiler and check that all
external controls, e.g. programmer, room thermostat etc. are
on. Allow the boiler to carry out a self check.
4. Set the burner on/off switch (A) to ON.

1 BOILER CONTROLS / DISPLAY
In normal operation the display (C) shows the boiler status (see
table above) and the water system ow temperature.
Blocking Mode
The boiler will enter blocking mode under certain fault
conditions. Whilst in blocking mode the burner is switched off.
Once the fault conditions are clear the boiler will automatically
reset itself. In blocking mode the display will alternate between
showing a '9' in digit one, along with the ow temperature in
digits 2, 3 and 4, e.g.
Followed by the blocking code 'bxx', e.g.
Error Mode
In error mode the display will ash on and off with the error code
shown, e.g.
The boiler will enter error mode under certain fault conditions.

The unit will be inoperative until the fault is rectied. The reset
button is used to reset the boiler control module after an error
has occurred.
Self Check and Anti-Seize Modes
After switching on the mains power or after a reset, the boiler
performs a selfcheck, i.e. the DHW valve (if connected) is
energised rst for 15 seconds then the CH pump is switched on
for a further 10 seconds. This cycle repeats itself every 24hrs,
as long as no heat request is given in 24hrs.
Burner on/off Switch
With the burner switch set to 'off' the boiler will not respond to a
CH demand. However, it will respond to a DHW demand and the
pump anti-seize and frost protection modes are still operational
any one of which could cause the boiler to re. Note. The burner
switch is NOT a mains isolation switch.
CH/DHW Systems
In standby mode pressing and holding the '+' button for 3
seconds turns the CH system on/off.
In standby mode pressing and holding the '-' button for 3
seconds turns the DHW system on/off.

is left, after 20 minutes it automatically returns to 'standby' mode.
Parameter settings and limits are listed below.
Parameter mode is entered from standby mode by pressing the 'mode' button once.

To shut Down the Boiler
1. For short periods
Set the external controls to OFF. Wait 10 minutes and then
isolate the mains supply to the boiler.
2. For longer periods
Set the external controls to OFF. Wait 10 minutes and then
isolate the mains supply to the boiler. For longer periods the
entire system should be drained, including the domestic hot
water supply.
To Relight the Boiler
Rell the system if it has been drained, taking care to ensure no
air is in the boiler or system.
Repeat the procedure detailed in 'To light the boiler'.
Frost Protection
The IMAX XTRA b oiler has built into its control system the
facility to protect the boiler only against freezing.
Note.
This may not protect remote parts of the system, in which case
a separate frost thermostat should be tted.
Boiler Overheat
Boiler overheating is detected by electrical sensors connected
to the boiler control module. If the boiler overheats it will shut
down and the display will show E18. Press the 'reset' button (D)
and the boiler will relight. If the fault recurs turn off the boiler
and consult a CORGI registered installer or in IE a competent
person.
Condensate Drain
The condensate drain must not be modied or blocked.
Blockage of the condensate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler or leakage from the
condensate trap mounted on the bottom of the boiler.
If freezing is suspected and the pipe run is accessible an attempt
may be made to free the obstruction by pouring hot water over the
exposed pipe and clearing any blockage from the end of the pipe.
If this fails to remedy the problem the assistance of a CORGI
registered installer or in IE a competent person should be sought.
Escape of Gas
Should a gas leak or fault be suspected contact your local gas
supplier without delay.
Do NOT search for gas leaks with a naked ame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains use a damp cloth and mild
detergent.
DO NOT use abrasive cleaning materials.
