The safety valve must be connected to the boiler outlet and no other
valve or flap must be interposed between it and the boiler.
Minimum safety valve flowrate as a function of maximum boiler nominal output :
Minimum relieving capacity
Maximum gross boiler output
(a) = kW, (b) = Kg/h, (c) = MBtu/h, (d) = lb/h

Connecting the condensates discharge conduit
It is imperative that a siphon (optional equipment) be connected to
the condensates discharge pipe to prevent any leakage of
combustion products.
The condensates in oil-fired condensing boilers are acidic. We
recommend the installation of a condensates neutralisation system to
protect the pipes and the environment.
