Vulcan Steamer.....

[generaltech1]

m#: VHL2G

Ignition locks out
If it does fire, it sounds like a train.

Any ideas?

www.vulcanhart.com..... have you checked the gas pressures? Flue? traps?

Hey Moose...Been there, done that, got the t-shirt.

I think this model has flame rod in it down the burner tube. these burners have been updated to pick up combustion air. These flame rods have to be properly adjusted as to not miss fire. If out of adjustment or worn they will sound like h##l. Also the it sound fire up into high burn after pilot with out lag. if that is correct you may have air screen on blower out of adjustment or dirty.

Hey H-T, Yes it does have a spark rod, & I downloaded the manual but it says nothing about rod adjustment. It doesnt appear to have any specific information. Can you enlighten me?
Thanks-

I think this model sets like the vhx 24g. If the unit has the new style combustion proving switch that is sensing on the manifold. the rod has a cord grip holding it in the burner. From tip of spark plug tip to end of the cord grip it is 1 1/8- 1 3/4. Put a mark on porcelain fire unit if it don't clean fire rotate rod retry. make sure the rod is clean. They are terrible about fouling. Also make sure the ground wire is good to burner and the grounding tit is clean on air screen on the end of burner.

Can I call you or chat about this unit? It also seems to be dumping water constantly, I ordered a pressure valve for it, and although the p/n is right, the pressure rating is wrong. The one on the unit is 475psi the one that shipped was 438. Ive tried VulcanHart, but theyre not much help.

TIA

It's dumping water? From drain or pop off valve? This unit has 2 pop off valves one is set at 13psi and the other is 15 psi. Did you get the unit fired properly? If so what was the steam pressure? It should be burner off at 9-10 psi steam and cycle on at 5-6. This is for vhx 24 g which is in the same family. I know the valves are the same I just looked at parts breakdown. This unit has a condensate cooling valve is this what is leaking? Leave me a way to get in touch and I will help with what I can.

You get it running?

[generaltech1]

Hey HT, sorry I didnt get back to you sooner, but I have been EXTREMELY busy. Anyway not as yet, and I pulled the burner assy out and for the 2nd time the insulator is cracked/broken, tips are fouled, and doesnt want to fire. I really need some specifics on how to align it properly.
Also yes it dumps water constantly, even when off/unplugged.
Please respond ASAP thx

I know busy I have did over 17 grand since Tuesday morning. You can get part number from vulcan site on probe or hobart office don't know how close to you they are. This unit has water fill solenoid that could have trash in it or the condenser solenoid. they or in the control box on left had side follow your tubing to see which is what. I think top is fill. Also this has a condenser t-stat this could be allowing to run due to out of adjustment. You will need probe to get to fire proper. clean the grounding post with emory cloth if not you will have to get a burner that part isn't sold by itself if it is eroded away. then follow the other post I left.to set up.These unit are very sensitive and have to be tuned in.

Is there anywhere to get an actual technical service manual for this unit. The Vulcan manual I was able to download from thier site(Installation and Operation) is of no help at all ? I have a 3rd, yes 3rd, ignitor/sensor rod on the way, probably going to replace tommorow, so I really need to know how to set this correctly, as far as gap/position.
Heres whats happened so far. I cleaned the burner assy, ground tip, and the little area on the end of the burner that i'm guessing is the area where its supposed to arc, and the screen. Im also guessing that flame rectification is used to prove the pilot to light off the main valve. And by that I mean the pilot completes the circuit between sensor and ground tip, correct?
It seens as though after the rods have been replaced, it works really well for about 3 days before it starts to act up again. Then, when I inspect the rod, the insulator is all broken at the end. So I assume its not positioned correctly, lp gas pressure is right on the money.
I was told that there was a Hobart service manager that came out to look at it a while back and after about 1500 in parts, it started acting up again. So im not exactly sure where to go from here, but I need to get it solved

Thanks for any and all advice you can give,

Jerry

I worked for Hobart for a short time. They have pretty tight security on their manuals. The only way to get the tech manuals is to actually go to the Hobart Cooking equipment school in Troy Ohio. I was scheduled to go two weeks after they laid me off. The manuals do exist in CD form but I worked for Hobart and I could never get a copy. I'm sorry, that is no help but it is important information. Vulcan is a subsidiary of Hobart which is a subsidiary of ITW which is a Fortune 50 company. That was not a typo Fortune 50 not Fortune 500.
