I have a 31ER1HT, question is..Can I fit this instead, they have the same connections. What do the numbers signify? Thanks Rob October 25, 2008 at 12:52 pm #266487 WashmanParticipant Re: Energy regulators Hi I think the difference between 30ER and 31ER is the 31 ER has pilot light switch and the 30ER hasn’t.
