(1) It is not allowed to use any other roof flue terminal. You can order the roof flue terminal mentioning the item number with A.O. Smith, manufacturer or wholesaler’s.
3.9.4Parallel connections
The table gives the maximum pipe length for parallel systems. The maximum pipe length depends on the selected diameter.
Warning
Mount flue gas discharge material with a fall of 5 mm per metre towards the device.

(1) The given larger diameter can be used if the maximum running length is insufficient. When using a larger diameter, this shall be used for both the air supply and the flue gas discharge.
Use the longest pipe for calculating the pipe length. If, for example, the flue gas discharge pipe is 10 metres and the air supply pipe is 15 metres, use the 15 metres for calculating the length. Then add the Lequivalent to these 15 metres for each 90° and 45° bend in both the air supply and the flue gas discharge. All this will be explained using a practical example.
