When trying to operate the boiler make sure that :
- All gas supply cocks are open and that the gas supply has
been purged of air.
- Electrical supply and water isolation valves are open.
WARNING: Always isolate the boiler from the electrical supply
before carrying out any electrical replacement work.
Always check for gas soundness after any service work.
Should there be any doubt about the voltage supply to any of the
components, it is possible to carry out a simple electrical test to
ensure all is operational in that area.
