Well I am in the water test stages. During the first test I discovered the pitfalls of running my wires through the frame with the burner configuration I have.
Frame made of 2x2x1/8 mild steel. The burners are hurricane burners.
Discovered that the direct connection of the burners to the upper frame allows for a much higher heat transfer to the frame.
Melted the insulation on a couple of wires. Luckily i discovered it before any shorts.
Re-wired and all is well, KIND OF.
Using 2 Honeywell Y8610U. Intermittent gas flow valves with pilot lights with Honeywell control modules.
Problem I am having is this...
I fill the keggles with 8-9 gallons of water. no leaks thank god... Plug in the RTD leads. Hit the main power switch. Beast comes to life. PIDS glow and all is WAY COOL!!
Throw the switch to the HLT gas valve to auto, Pilot sparks and lights. Valve clicks open and feeds gas to the burner, PRESTO I am cooking water.
Open the ball valves and prime the march pumps and the recirc begins. water temp comes up and all is way cool.
Same procedure for the MT. After a minute i notice the PID is flashing off and back on again which is causing the module to malfunction shutting off the gas and killing the burner. After as second or two the PID comes back to life and fires the pilot then the burner. Then dies again. I figure OKAY a bad PID. No problem get another one and lets rock.
Then after a home brew and sitting there watching the HLT continue to work properly. and VERY puzzled, The HLT hits a test temp of 150*f and shuts down just as it is supposed to do. I am VERY excited now. Pump still going on the HLT Temp stays at 150-151 FOR EVER it seemed. (I liked this)
I think HEY lets try the MT again. So I fire it up and it comes to life at 90*f and runs perfectly for about 10 minutes. The HLT drops to 149*f No Problems. No flashing PID, No flame out, PERFECTLY.
UNTILL, you guessed it, the HLT drops below 148*f and the PID calls for heat and the gas valve fires the pilot light and then the burner. Right on que, the MT PID and gas valve go into vapor lock and I have to shut it down.
I am VERY concerned at this point.
HLT: Works PERFECTLY, PEROID
MT: Works perfectly as long as the HLT burner is not running. With the HLT running PERFECTLY it has an attitude display.
What the hell is going on here?
What I know:
All is wired correctly
No Shorts during the melt down.
When each is fired individually they work perfectly.
When are fired together, the HLT continues to work perfectly and the MT has a fit.
Burners are running at MAYBE 20%, not throttled all the way up by any means.
Can anybody please give me some ideas?
I was thinking that the gas is low and thus causing the gas valve, which monitors pressure and will shut down if it is too low, to malfunction and cause the problem. but why just the MT and not both? Is it that simple? can the "Down Stream" burner be affected this easily?
I have ONE transformer to power both modules and PIDS and gas valves. MORE than enough power to cover all that. It acts like a power failure, but again why not BOTH? Why just the MT set-up?
Sorry for the book here
