    To check the LOW pressure switch operation, slowly increase the LOW pressure switch setting from its standard setting of 3 inches water column with the burner operating. At some point the burner should shut down and a LOW gas pressure fault should be indicated on the CRT screen. Position the LOW pressure switch back to 3 inches water column. Proper operation of the LOW pressure safety switch has now been verified
