Boiler Design and Clearances

Description

These boilers are designed to provide central heating from a

fully pumped open vented or sealed water system and domestic

hot water using a fully indirect cylinder.

Once the controls are set the boiler operates automatically.

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.

Compartment or Cupboard Installations

Ventilation is not required for compartment or cupboard

installations. Do not use the compartment or cupboard for

storage.

Boiler Safety Devices

Boiler Shutdown

The boiler software is designed to recognise the potential for

an overheat lockout and will shutdown before this happens.

To restart the boiler, press the reset button, see diagram 2.

If the boiler fails to resume normal operation and all external

controls are calling for heat, then call your Installation/Servicing

company or Glow-worm service.

Frost Protection

With the gas and electric supplies ON and irrespective of any

room thermostat setting, the integral frost protection device

will operate the pump when the temperature of the boiler

water falls below 8OC.

The pump will stop after 10 minutes if the temperature is

higher than 10OC or has already reached 35OC.

The burner will only activate if the boiler temperature does not

reach 10OC after 30 minutes or at any time if the temperature

drops to 5OC.

The burner will switch off when the temperature reaches

35OC.

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 or Glow-worm service if the

fault persists.

www.glow-worm.co.uk

General Note

Servicing/maintenance should be carried out by a competent

person in accordance with the rules in force in the countries

of destination.

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

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.

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.

Servicing, Maintenance and Spare Parts

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.

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 and model of the boiler.

The name and model badge is 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.
