Boiler Design

These boilers are designed for use as part of a sealed water

central heating system with fully pumped circulation. The

pump, expansion vessel and associated safety devices are all

tted within the boiler. The hot water PRE HEAT temperature

facility will improve the boilers hot water delivery response.

The daily pump and 3 way valve exercise programme combined

with the built-in frost protection will help to maintain and protect

the boiler.

Range Rating

The boilers are fully modulating for central heating, it is

therefore not necessary to range rate the boiler. However, if

desired, it is possible to range rate the max. CH output in 1kW

increments, refer to section 11.

Electrical Supply Failure

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 press the reset button. If

the boiler does not resume normal operation after this call your

Installation/Servicing company or Glow-worm service.

Overheating Safety

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 on the controls fascia.

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.

Safety Discharge Valve

A safety discharge valve and discharge pipe are tted to the

boiler. This valve must not be interferred with, should there be

any discharge from the pipe, isolate the boiler electrical supply

and call your installer or Glow-worm’s own service organisation

using the telephone number on the inside front cover of this

booklet.

Safety Devices

Frost protection

The appliance has a built in frost protection device that protects

the boiler from freezing. With the gas and electric supplies

ON and irrespective of any room thermostat setting, the frost

protection device will operate the pump when the temperature

of the boiler water falls below 8°C.

A timer is used so that the temperature can be checked

periodically. After 10 minutes the pump will be stopped if the

temperature is higher than 10°C or has already reached 35°C.

The burner will activate if the boiler temperature does not reach

10°C after 30 minutes or at any time if the temperature drops to

5°C.

The burner will switch off when the temperature reaches 35°C.

Condensate Drain Blockage

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

drain becomes blocked. During freezing conditions an ice

blockage in the condense drain, external to the house would

also activate the safety feature. Use warm cloths on the pipe to

release an ice blockage.

Once the blockage is removed the boiler should then restart.

Condensate Drain

A plastic drain pipe must be tted to allow discharge of

condensate to a drain. Condensate should, if possible, be

discharged into the internal household draining system. If

this is not practical, discharge can be made externally into the

household drainage system or a purpose designed soak away,

see section 8 for more details.

Pluming from ue terminal

Like all condensing boilers this appliance will produce a plume

of condensation from the ue terminal in cool weather. This is

due to the high efciency and hence low ue gas temperature of

the boiler. This is normal and not an indication of a fault.

Servicing, Maintenance and Spare Parts

Servicing and Maintenance

To ensure the continued efcient and safe operation of the

boiler it is recommended that it is checked and serviced as

necessary at regular intervals. The frequency of servicing will

depend upon the particular installation conditions and usage.

If this applaince is installed in a rented property 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 approved at the time by the Health and Safety

Executive in accordance 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 literature.

After servicing, complete the relevant Service Interval Record

section of the Benchmark Checklist located on the inside back

pages of these instructions.

Spare Parts

Remember, when replacing a part on this appliance, use

only spare parts that you can be assured conform to the

safety and performance specication that we require. Do not

use reconditioned or copy parts that have not been clearly

authorised by Glow-worm.

If a part is 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 appliance, this infomation will be

on the name badge on the front of the appliance.

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.
