8.5 Connection to the heating control system
A heating control system should be connected which can operate at least one heating circuit pump and the
voltage free burner requirement.
We are happy to provide suitable circuit diagrams and diagrams of other system solutions.
9 Flue Connection
The flue tube on the stove must be connected to the flue in accordance with the current Building Regulations.
Please contact your SHT dealer or your heating engineer for information on this subject. All flue pipes must be
designed to conform to current British Standards.
The EVO AQUA is able to operate with a flue draught between 5-15 Pa as the suction draught fan conducts the
exhaust gases safely into the flue. If the flue draught is higher than 15 Pa, we recommend fitting a draught
regulator in the flue. This must not draw air from the installation room.
In order to guarantee optimum combustion, the number of bends in the flue pipe must be minimised, no more
than four bends, and laid such that they rise towards the terminal. No reduction in the flue pipe cross-section
is allowed.
Standpipe: RKA1015
The standpipe, or starter pipe, is specifically designed to allow cleaning access and the attachement of a
flue draught stabiliser if required. The horizontal length can be reduced in size according to the individual
installation requirements.
