3.2. Flue Requirements
General
The following information sets out the flue requirements for these models.
3.2.1. Masonry Flue
1. The flue serving this appliance shall have no cross sectional dimension less than 175mm
(7”) e.g. 225mm (9”) by 225mm (9”) Masonry chimney or 175mm (7”) diameter clay liner
and a minimum height of 3 metres (10ft). For installation in GB, please refer to BS 5871
Part 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.
