    So came across 3 of these units and went into extensive lengths with tech support about operation etc... whoever posted up 500mv is right, tech said the same thing, working on one

    right now that was converted to propane and the pilot due to restriction/pressure issues exploded/released pressure after installing 2 new thermopiles polarity sensitive like explained

    above just use your little mirror and reference the bottom of the valve to line up the thermopile connections. So the first two systems that I came across it was the valve and no

    matter I did the led would blink normal/no error code fan would ramp up and on and nada. So tested pressure/mv/valve/remote to no avail nothing. Called tech to verify what

    I did and it was pretty much a expensive conversation which bummed me out, who wants to tell a customer that the valve is no longer available and that you'll have to do a complete

    change out valve/pilot assembly or get a new unit? So this system that I am working on now was pretty surprised that is was in working order until the pilot hood blew. Initally when I

    showed up the system had servere sooting/no visible signs of pilot tube/hood failure when I let it sequence for 20 minutes heard a loud pop and a small fire under the pilot cap where

    it was not suppose to be): Haven't went back to perform the whole assembly change out because their supply pressure to that unit and another lennox in the bedroom were off and

    they are waiting for the propane supplier to bump it up/check out the issue. So my opinion on this system is that they f'ed up on putting a remote/board/valve all in one. Who wants

    to just go off a LED light to change thermopiles, change them and still back at square one. So going to have that cut your losses talk with the homeowner before I order the part, and

    let them make the choice to invest in the old system or a new one.

    I just joined the forum. I'm looking at the pages above you were nice enough to post. I have a honeywell rv8310 in a Majestic DV360. The pages are very helpful. I have a pilot that won't stay lit and I have replaced the thermopiles which generate 690mv and 790mv and light the led on the valve (blinks normally) but as soon as I let up on the pilostat the pilot goes out. I'm getting ready to replace the valve but I see on page one of the four pages you posted it says "should the pilot drop out, there is a safety interlock on the valve which must be reset before the pilot can be re-lit". I don't see such a safety on the valve. Do you know where this is and how I'd reset that? Thanks. Ron
    I believe I have the same issue. Replaced thermopiles and I’m seeing 400+ on each with the pilot light on (pushing in button). As soon as I release the pilot light goes out.

    I can’t post a link to the manual ( not enough posts) but if you Google honeywell rv8310 it will be the first result.
