4 evacuation of combustion Gas

4.1 Regulation

Only flue accessories supplied by Glow-worm

must be used.

Different flue outlet configurations can be carried out.

• Consult your supplier for more information about the other

possibilities and associated accessories.

44 mm/m

• Standard flue terminal kits have an in-built fall back to the

boiler to drain the condensate. These can be fitted level

between the appliance and the termination position. All

other extended flues must have a fall of at least 44mm/m

The maximum length of the flue outlet is defined according to

its type (for example C13).

• Whatever the kind of flue system chosen, observe the

minimum distances indicated in the chart below to position

the flue terminals.

• To install the flue, refer to the separate flue instruction

supplied with your appliance.

• Explain these requirements to the user of the appliance.

a

If necessary, you must install terminal

protection.

Caution! The connection between the flue

elbow and the flue outlet must be sealed.

In Gb the minimum acceptable siting dimensions for the

terminal from obstructions, other terminals and ventilation

openings are shown in diagram overleaf.

In Ie the minimum distances for flue terminal positioning must

be those detailed in I.S.813 “Domestic Gas Installations”.

The terminal must be exposed to the external air, allowing

free passage of air across it at all times.

Being a condensing boiler some pluming may occur from

the flue outlet. This should be taken into consideration when

selecting the position for the terminal.

Carports or similar extensions of a roof only, or a roof and

one wall, require special consideration with respect to any

openings, doors, vents or windows under the roof. Care is

required to protect the roof if made of plastic sheeting. If

the carport comprises of a roof and two or more walls, seek

advice from the local gas supply company before installing

the boiler.

If the flue terminal is positioned near a light

source insects may enter the flue system.

Where safe and practical to do so advise the

homeowner to check the flue outlet and clear

visible insects from the terminal end.

H* and J* See diagram 4.2. These dimensions comply with

the building regulations, but they may need to be increased to

avoid wall staining and nuisance from pluming depending on

site conditions.

Terminal Guard

A terminal guard is required if persons could come into contact

with the terminal or the terminal could be subject to damage.

If a terminal guard is required, it must be positioned to provide

minimum of 50mm clearance from any part of the terminal and

be central over the terminal.

The guard should be similar to that shown in diagram 4.1.

A suitable guard is manufactured by: -
