WARNING: Risk of fatal Injury from explosion of
flammable gases!
▶ Installation, connection of the fuel supply and flue
pipe, commissioning, connection of the electrical
power supply, servicing and repair may only be
carried out by an authorized heating engineer.
▶ Any work on gas-carrying components may only be
carried out by an authorized gas installer.
The local regulations regarding minimum pressure detectors and low-
water safety cutouts must be observed. Installation and operation must
comply with the device manufacturer's technical documentation.
We recommend fitting an 80 mesh dirt filter externally to the boiler
return to prevent contamination of the boiler by the water source.
Leak test
A leak test must be carried out. The testing pressure is based on the
normal operating pressure of the heating system and should be 1.3
times that pressure, and in any case no less than 14 psi (1 bar).
The details on the boiler rating plate are definitive and
must be observed.
