Introduction

The IMAX XTRA E 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 Gas Safe Registered

Engineer or in IE a competent person, in accordance with the

above regulations.

The appliance should be serviced at least once a year by a Gas

Safe Registered Engineer 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 7A for E320-E560.

This appliance is intended to be connected to the supply via two

double-pole switches, having a 3mm contact separation in both

poles, serving only the boiler and system controls. Alternatively,

two 3-pin UNSWITCHED sockets may be used.

Important Notes

• This appliance must not be operated without

the casing correctly tted.

• 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

Gas Safe Registered Engineer 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 Gas Safe

Registered Engineer 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.

Minimum Clearances

Rear:

1000mm or adequate space from the rear of the jacket to make

the ue connections and access to the ue sample point, drain

connection, ue and any safety or control devices.

Left Side:

450mm.

Right Side:

450mm.

Front:

600mm; except, access doors may be closer, but not less than

200mm and 600mm must still be available for service across the

width of the boiler.

Top:

500mm.

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.

The boiler will commence the ignition sequence, supplying heat to

the system when required.

BOILER CONTROLS / DISPLAY (MASTER PANEL SHOWN)

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 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.

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 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 protection 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 Gas Safe Registered Engineer 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 Gas

Safe Registered Engineer 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.
