Appliance with parallel flue gas discharge material
The longest pipe must be used to check the maximum length. In this case, the
chimney pipe is the longest. This is 25 metres. This 25 metres is the sum of pipe
sections 1, 2, 3, 4 and 5. The length of the transition piece can be ignored. The
total number of bends used in the flue gas outlet and air supply is 8. The bend
in the transition piece can be ignored. According to the table, 4.6 metres must
be added for each bend. This brings the total pipe length to:
(4.6 x 8) + 25 = 36.8 + 25 = 61.8m.
This is less than the maximum length of 80 metres stated in the table. The
installation therefore fulfils the requirements.
