When installing as a fan assisted conventional flue appliance models EF150-EF180 are factory supplied in a Twin-pipe configuration so only
require an Air inlet guard as below
Due to the large Flue pipe size required Lochinvar does not supply conventional flue components for models EF150,
EF180 except the air inlet guard. For this installation type a flue system designer/installer should be consulted.
8.8.2 Maximum length – conventional/twin-pipe flue
The maximum length of the flue system is determined by the resistance of the components within the flue When a conventional or twin-pipe
flue is to be used, the maximum length of the flue system is limited by the combined resistance of the inlet (if used) and outlet flue components
as detailed in the following tables.
The resistance must not exceed 200 Pa.
The information shown in table 8.6.12 is for the Lochinvar supplied flue system only; other flue system suppliers
may have different values.
