LUE ISCHARGE
The flue system must ensure safe and efficient operation of the equipment to which it is attached, protect the combustion process from wind
effects and disperse the products of combustion to open external air.
The flue must terminate in a freely exposed position and be so situated as to prevent the products of combustion entering any opening in a
building.
For further information on terminal locations, please refer to Section 8.3.1.

YPE ONVENTIONAL
To convert the EF80 – EF120 to conventional flued operation, the approved air intake grille should be fitted to
the concentric flue spigot. The grille will have an opening in the top plate that allows the connection of the flue
system to the exhaust port of the Water heater.
When the heater is installed as a Type B

Height A
This is the height of the air inlet. A rain hood should prevent rainwater entering
the air supply system.
When the inlet and outlet are mounted on a flat roof, the inlet should be at least 60 cm
above the roof surface and at least 30 cm above the maximum snow level.
Example 1:
When the maximum snow level on the roof surface is 45 cm then the air inlet should
be at 45+30=75 cm. 75 cm is more than the minimum 60 so the height will be 75 cm.
Example 2:
When the maximum snow level on the roof surface is 15 cm then the air inlet should
be at 15+30=45 cm. 45 cm is less than the minimum 60 cm so the height will be 60
cm.
Height difference B
This is the distance between the flue outlet and the air inlet.
The flue gas outlet should be at least 70 cm above the air inlet. It is advised to be
equipped with a conical outlet.
When no air inlet connection is applied on the roof, the flue outlet should be
situated at least 100 cm above the roof surface.
Distance C
The horizontal mutual distance at roof level.
This distance should be at least 70 cm.
