Burner Relays are Required for 12-Volt Burners

The reason many 12-Volt Burners fail prematurely is because the ‘hammering shock’ the components receive from the 12-volt source. This relay acts as a ‘shock absorber’ for 12-volt electricity before it passes it along to the burner.  When you install this relay, you will dramatically extend the life of your flow switch, thermostat, hi-limit switches as well as the fuel pump solenoid.
