CONVENTIONAL FLUE

A - Boiler

B - Flue

C - Max. 2 bends at 135°

D - Anti down-draught terminal

E - Chimney

• Open (conventional) flued appliances must

not be installed in a bedroom, bathroom or

bedsitting room.

• The flue system must be in accordance with

BS 5410 : Part 1 and the current Building

Regulations.

• The flue must be constructed of materials

suitable for use with condensing combustion

products.

• External flue systems must be of the insulated

type.

• Brick and masonry chimneys must be lined

with a suitable non-combustible material and

properly jointed to withstand the effects of

the working temperature (minimum rating of

material 120°C) of the appliance and any

condensate which may form.

• All flue joints must be sealed to prevent the

leakage of condensate and combustion

products.

• Ensure that joints are made so that the

condensate runs away and is not collected

within the joint.

NOTE: The flue can be increased in size from

the boiler take off point providing the joint is

correctly sealed. Never reduce the flue diameter

from the boiler take off point.

CF Sizing:

• 32/50 & 50/70 = 150mmØ

• Because the flue operates at a lower

temperature on a condensing boiler

compared to that of a conventional

appliance, the flue draught will be lower.

Typically the draught will be between

0.5mmwg and 4.4mmwg, measured with the

flue warm but the burner not firing. The actual

figure will vary depending on weather

conditions, flue height and position.

• The flue should be vertical and contain as few

bends as possible, a maximum of two 135°

bends should be used.

• The flue outlet must be extended beyond the

eaves of the building and where possible,

above the apex.

• Fit a suitable anti down-draught terminal

where down draughts are experienced.
