Backup boiler Since electrical power will be available as a cost competitive fuel in the future, the PARAT Electrode boiler will also be a valuable backup boiler in case of breakdown in the fired boilers or in the fuel distribution system. No other boiler alternative can be ready from cold condition to full load in 5 minutes.
Theses test that I'm performing are standard tests that have to be preformed on a gas boiler before you service that boiler. The four tests to be completed are earth continuity, short circuit, resistance to earth and polarity. Three tests are done with the boiler isolated and obviously polarity is a live test.
must be wired on the same electrical circuit as the boiler. • For Direct Vent units, a carbon monoxide detector that is wired on the same electrical circuit as the boiler is strongly recommended. Boiler water — • Have boiler water chemistry checked at least annually by a qualified service technician.
