Millivolt conversion

fixitguy Member Posts: 91
I'm converting a Peerless 63-04L to millivolt, does anyone have a clue as to which gas valve to use?

    You will be using gas for nothing gained! You are lowering your system efficiency!

    it is not a good idea. Voids warranty and causes liability issues as well as violates gas codes.

    makes perfect sense

    #1 The system runs without power, maybe in some places the power never goes out, but around here it does a couple of times each winter. #2 In the northeast, a standing pilot is not a bad thing, lots of damp basements and rusting boilers. #3 In my experience, spark boxes fail on weekends and holidays, when the suppliers are closed.

    the reason more people arn't touching this thread

    is that we are not supposed to do what you suggest..that said, many of us have done it..we have areas here that will sometimes lose power for a couple days straight in winter..so i know where your going with this.

    Problem solved. simpler system at the least. PP mount fits in place of spark plug perfectly.

    In 1979 the mandate came

    for dual seated gas valves to replace all single seated valves being manufactured from that time forward. This was the sad end of Powerpile systems, they did however allow some transition using a back up safety such as a extra limit set to around 230 degrees F. Or in the case of steam wiring in an additional pressuretrol to kill the millivolt feed to the pilotstat portion of the gas valve in the event of over pressure. So you would have the normal P'trol set to say 2lbs off .5 on and the safety to shut off at 14 lbs back on at 9 lbs. Seeing as you have already made the change I suggest you do this for added safety and for the sake of at least offering some redundancy to the system. Honeywell makes a junction block Q313B generator that will make wiring this easier. If you need any assistance contact me at gastc@cox.net .
