Important Information

Boiler Design

Description

Xtramax HE Model: The boiler is designed to provide central

heating and instantaneous hot water.

Once the controls are set the boiler operates automatically.

Compartment or Cupboard Installations

Ventilation is not required for compartment or cupboard

installations.

Do not use the compartment or cupboard for storage.

The minimum clearances to ﬁxtures are shown in

diagram 1.

Pluming from ﬂue terminal

Like all condensing boilers it will produce a plume of

condensation from the ﬂue terminal in cool weather. This is

due to the high efﬁciency and hence low ﬂue gas temperature

of the boiler. It is normal and not a fault indication.

Electrical Supply Failure Reset Switch

The boiler will not work without an electrical supply.

Normal operation of the boiler should resume when the

electrical supply is restored.

Reset any external controls, to resume normal operation of

the central heating.

If the boiler does not resume normal operation turn the mains

reset switch off and on. If the boiler does not resume normal

operation after this the overheat stat may have operated.

+ A removable compartment door can be placed

at least 5mm in front of the appliance

Boiler Safety Devices

Overheat Reset

The boiler software is designed to recognise the potential for

an overheat lockout and will shutdown before this happens.

To restart the boiler. Turn the mains reset switch 0, wait for

ﬁve seconds, turn mains reset switch to I, the boiler is reset,

see diagram 2.

If, however the boiler fails to resume normal operation and

all services and demands are calling for duty then call your

Installation/Servicing company.

Overheat Lockout

In the event of the boiler overheating the safety device will

shutdown the boiler. If this happens, call your Installation/

Servicing company.

Frost Protection

The boiler has a built in frost protection programme as long

as the electricity and gas are left switched on. This device

operates the burner and system pump when the temperature

in the heating circuit falls below 40C.

When the temperature inside the boiler rises to 70C the

burner will switch off and only the system pump will run, at

100C the pump will switch off as frost protection will no longer

be required.

NOTE: Any other exposed areas of the system should be

protected by a separate frost thermostat.

Condensate Drain Blockage

As a safety feature the boiler will stop working if the condensate

drain becomes blocked. During freezing conditions this may

be due to the forming of ice in the condense drain external

to the house. Release an ice blockage by the use of warm

cloths on the pipe. The boiler should then restart. Contact

your installation/servicing company if the fault persists.

Safety Discharge Valve

A safety discharge valve and discharge pipe is ﬁtted to the

boiler. This valve MUST not be touched. If there is any

discharge from the pipe, switch off the boiler electrical supply,

then call your Installation/Servicing company.

Spare Parts

REMEMBER: When replacing a part on this boiler, use only

spare parts that you can be assured conform to the safety

and performance speciﬁcation that we require. Do not use

reconditioned or copy parts that have not been clearly

authorised by Glow-worm.

If replacement parts are required contact Glow-worm’s own

service organisation using the telephone number on the inside

front cover of this booklet.

Please quote the name of the boiler, this infomation will be

on the name badge on the front case.

If in doubt seek advice from the local gas company or

Glow-worm’s own service organisation using the telephone

number on the inside front cover of this booklet.

Servicing

To ensure the continued efﬁcient and safe operation of the

boiler it is recommended that it is checked and serviced at

regular intervals. The frequency of servicing will depend upon

the site conditions and usage, but in general, once a year

should be enough.

If this boiler is installed in a rented property in the UK there

is a duty of care imposed on the owner of the property by

the current issue of the Gas Safety (Installation and Use)

Regulations, Section 35.

Servicing/maintenance should be carried out by a

competent

person inaccordance with the rules in force in the countries

of destination.

To obtain service, please call your installer or Glow-worm’s

own service organisation using the telephone number on the

inside front cover of this booklet.

Cleaning

The boiler casing can be cleaned using a mild liquid detergent

with a damp cloth, then a dry cloth to polish.

Do not use any form of abrasive or solvent cleaner as you

may damage the paintwork.

Frost Protection

If the mains electricity and gas services are to be turned off for

any long periods during severe weather, it is recommended

that the whole system, including the boiler, should be drained

to avoid the risk of freezing.

Maintenance

www.high-efﬁciency.info

1. Check that all isolating valves are open, see diagram 5 and water ﬂows from the hot water taps.

2. If you are in any doubt about the boiler being ﬁlled with water contact your installer or Glow-worm's own

service organisation using the telephone number on the inside front cover of this booklet.

Do not operate the boiler without water.

3. Check that the electrical supply to the boiler is ON and set any remote controls as required.

4. With the User controls in their "OFF" (0) positions, turn the Mains Reset Switch to the ON (1) position,

the running lamp will initially illuminate (green) then go off, the system pressure will be displayed and should read

on the digital display, at least 0.7bar (recommended 1.0bar), if less, pressurise as described in the Digital/Display

System Pressurisation section.

Digital Display/System Pressurisation

The digital display, see diagram 4, normally shows the operating temperature of the unit when there is a central heating demand

and gives a pressure reading when there is no demand or when the appliance is in the domestic hot water mode.

If the digital display shows pressure less than 0.7bar, re-pressurise the system to 1bar by gently opening the built in ﬁlling tap

underneath the boiler, see diagram 3. A tap extension tool is provided to facilitate this. Ensure the tap is closed. If the system

repeatedly looses pressure, YOU MUST CONTACT YOUR INSTALLER OR GLOW-WORM'S OWN SERVICE ORGANISATION

USING THE TELEPHONE NUMBER ON THE INSIDE FRONT COVER OF THIS BOOKLET.

If there is a fault, then a fault symbol displays and the control light on the control panel ﬂashes red.

WARNING: Never try to service or repair the appliance by yourself and only start the appliance once a skilled professional has

repaired the fault.
