3.2. Flue Requirements
Class 1
- A flue having
no cross sectional dimension less than 175mm (7”) e.g. 225mm
(9”) by 225mm (9”) Masonry chimney or 175mm (7”) diameter clay liner.
Class 2 -
A flue having
no cross sectional dimension less than 125mm (5”).
Class 2 - Pre-cast -
A flue constructed of pre-cast concrete/terracotta blocks conforming
to BS EN 1858 or BS 1289:Part 1 and having a minimum cross sectional area of
12,272mm
2
with the smallest dimension being no less than 63mm.
1. All flues require a minimum height of 3 metres (10ft). For installation in GB, please refer to
BS 5871 Parts 2 for further information. For installation in IE, refer to the current edition of
I.S.813 “Domestic Gas Installations”.
2. A faulty flue or chimney may result in smoke and fumes entering the room.
3. The flue should be sound, free from obstructions and, if it has previously been used with a
solid fuel or oil fired appliance, it should be swept before installing this gas fire. The flue
must be inspected annually to ensure continued clearance of combustion products.
4. Any flue damper plates or obstructions etc. must be removed and no restrictor plates shall
be fitted. Where removal is not practical, the damper plate/restrictor must be fixed
permanently in the fully open position.
Note: To comply with the expression “permanently fixed in the open position”, a
mechanical fixing that prevents user intervention should be used e.g. requires
the use of tools for removal.
5. It is recommended that a smoke test be carried out before installation to ensure that there
is no spillage of fumes into the room. If spillage occurs this problem must be rectified
before commencing installation.
6. The flue must serve only one appliance.
7. If any terminal, cowl or chimney pot is fitted on the flue, ensure that it is suitable for use
with this gas fire and the flue system and does not restrict the cross sectional area of the
flue. Please consult the manufacturer of the terminal/cowl/chimney pot for guidance.
