burnham revolution question

Unknown

Based on everything you have told me thus far, it appears that your boiler has been modified by someone. You stated that you have an S8670E Ignition Module in your earlier posts. The RV has been equipped with ONLY the Honeywell Smart Valve until December of 2004 when it was configured with the S8670E and VR8204C gas valve.As I stated in my last post, the Smart Valve has the ignition module built into it so you won't see one...only a gas valve. You are going to have to determine what you have first before we can help you. If you want, I can try and get our Field Technical Service agent down to Waltham to help you out with this. He is based out of Southern NH. E-mail me at the address below with your name and phone number and I'll have him get in touch with you first thing in the morning.

burnham revolution question

RV3 boiler about 3 years old... Had non related pipe burst above boiler and flood cellar. Today leak resolved. Boiler will not go do full power up. Have a.c. power. The little module on left (the one that controls the internal circ pump) has green power led & the one beneath it flashes around every 3 seconds (which I think is normal for cold boiler). Have motor running. Have draft in firebox. After powering up I hear faint click at around 20 seconds and then a very quiet one a few seconds later.

The question is: if I monitor the 24 volts on Honeywell S8670E ignition module should that 24 volts be present all the time or will that only be a short time??? Didn't have meter on board today & due to Saturday no parts around didn't dig into it more.

My guess is this was flooding for hours before anyone arrived.

TIA.

Question

A year old Revolution would not have been equipped with an S8670E ignition module. They were equipped with the Honeywell Smart Valve until just recently. Has this one been converted to spark ignition somewhere along the way or recently after the flood? Provided it has been converted correctly and is wired correctly, where is the wire from the S8670E "Burner Ground" terminal connected? Is the pilot trying to light? Electronic ignition systems need a good source of ground to the pilot assembly and to earthen ground to operate correctly. The Smart Valve got its ground through the connected pilot tubing to the valve. The S8670E needs a good source of ground to the pilot assembly by means of a ground wire connection to the VR8204C Gas Valve. You've got me a little concerned about this one because as far as I am aware, there are no factory conversion kits to convert the RV to spark ignition. When we recently changed to spark ignition on the RV (12/04) the wiring harness and controls changed as well. Hope this helps.

Been no mods on this at all. It was one of four installed summer of 2001. Pilot is not lighting. Hear no spark at all. That is why I am wondering if I place leads on electronic ignition should I see 24 volts constantly OR will it time out?

There was a lot of water that came down on top of the boiler - enough to make an 800 sq foot basement have an inch of water.

Also that little board on left side that I believe controls circ pump has power light on and the green led below flashes at maybe 3 second interval. If memory serves me correctly the lower lite is kinda monitoring the internal circ pump. And when the boiler gets over some temp I think that the circ pump is on constant and the lite is constant?

Off memory there on electronic ignition there were 2 molex plugs. One had maybe 3 (or 4 wires) & the other one had maybe 6 wires.

All documentation got soaked so I downloaded what I thought was correct wiring online.?

Where is the exact wiring located then for something this age?

I am not getting ignition so was thinking to check the 24 volts to electronic ignition for openers. Then go from there.

I have no heat, no domestic, a mad tenant, cannot get parts over the weekend... I want to do my homework now to resolve this Monday.

Well.......

As I stated, the Revolution has always been equipped with the Honeywell Smart Valve and Hot Surface Ignition until December of 2004. That configuration would have had a 4-pin square molex plug with 3 wires (yellow, pink and blue) that plugged directly into the valve and a rectangular plug with 4 pins (3 wires) that connects to the pilot assembly. There was no ignition module (S8670E) because it was integral to the Smart Valve. I have attached a link to the new (current) wiring diagram with the S8670E and VR8204C gas valve (The wiring diagram is on page 52). Also check the other three that were installed to see if they are configured the same way.

The VS3000 control for the internal circulator does have a green power LED that should remain on without blinking. The lower or yellow LED will either blink (fast or slow) or remain on solid to depict the speed that the internal pump should be operating at that moment. A slow blink depicts that the boiler water is cool and a fast blink will indicate water temperatures getting hotter. When the water temperature rises above 170F the light will begin to blink real fast and eventually stay on solid.

If at all possible, e-mail me with the serial number of this boiler. It appears that it has somehow been field converted and that concerns me. The serial number will indicate exactly how this boiler originally left the factory, where it went and how it was equipped. Hope this helps.

figure 31 / page 52

Is what I am looking at now. You can email me an attachment at my email address.

This boiler is 40 minutes away and when I go there I have no access to the web..

Am I interpreting this schematic correctly??? History is cold water pouring on top of boiler that was running. Boiler is used for heat and domestic.

Turn power on and hear fan running. Placing hand on intake for firebox I have a healthy draft. Boiler is not lighting - no spark. Gas valves are on. I do hear some faint click maybe 20 seconds after power applied and then a fainter one a few seconds later.

There is a controller on lower right side that had 2 molex plugs in it. And the spark plug wire. Should that module have 24 volts constantly or will it time out?

update

had someone drop me off the soaked manual today. A few quesions...


1. - Page 78 troubleshooting chart makes reference to "smartvale control". Is this the main gas valve?

2. - The manual flow chart page 70 makes a reference to the ignition module having a 30 to 45 second delay for prepurge. Where exactly is the ignition module located?

3. - Can I visually see the pilot though that little glass peephole?

4. - Who will have best stocked parts near Waltham Mass.?

TIA

Oreo, to help you out...

I'm providing two links. The first one is Honeywells brochure for the S8760 Ignition Module you have now. The second is for the Honeywell SmartValve that you are most likely supposed to have in there. Hope these are helpfull.

My concern with this situation is that this boiler seems to have been field modified. The wiring harness would have also have had to have been modified to do this. I'm concerned as to whether it has been done correctly or not as to not cause any safety problems. I want someone from our company to set eyes on this one.

I totally understand and agree with your concern. I posted these two links so he can understand better what a smart valve is as shown in his book as opposed to the spark retro parts he has in there now. Your absolutly right that the harness must have been at the elast cut up and if that's the case the unit is probably not wired right and coul be a saftey hazzard. More importantly, if the unit has been retrofitted, and anything goes wrong with it, now Oreo owns it as the last person who touched it, even if he didn't do the conversion.

no field retros done on it...

I did ask Glenn to have his local service rep call me in the morning. Hopefully he can fit me into his service call schedule. The whole top of this boiler got flooded for hours. At least its above freezing.

The first questions were based after looking at the documentation I downloaded online. I would not have known if they are the same until I look at the boiler on site. I looked at the downloaded schmatic & I asked a few questions.

Later on today I had someone drop off a manual that came with the boiler and there is a difference between manual and what I downloaded Saturday.

I am positive that no one has done any mod on the 4 of these that went in around 3 years ago. So they will be as they came from the factory.

We got leak resolved on Saturday and knew that we couldn't get parts on Saturday :-( And I didn't have a meter onboard that was working.

Question for Glenn

Will the older RV's continue to use the Smart Valve as a
replacement or will a factory replacement/conversion be coming out for the spark ignition?

Thanks

Yes

The older models will continue to use the Smart Valve for the time being. Hope this helps.

ignition system

Why has burnham replaced the smart valve ignition system? The brand of warm air units I use have also stopped using the smart valve.
