17.4 care with the use of
soldering flux
18.0 electrical
connection
The electrical connections to the Strata 1 boiler are made via discreet plugs and sockets (Weiland Type)
which are located within the boiler case and below the control panel.
Connections must only be made using appropriate diameter multi strand flex cables and cable entry
must only be via the rubber glanded cable entry points located at the bottom rear r/h side of the appliance.
If the boiler is to be room sealed flued then care must be taken to ensure the cable entries are reasonably
air tight.
For electrical connection plug/socket function and location see fig 20.
The Strata 1 boiler has heat exchangers fabricated from 316L stainless steel. It is most important that
the compatibility of any flux is checked with the flux supplier before use, and that any flux manufacturers
recommendations are strictly followed with regards to use in conjunction with stainless steel.
