Vulcan Hart experts?

[fixbear]

You won’t find a exact manual as they made many variations. It’s the ML number that is important on Hobart machines. Vulcan Hart is part of there group that now belongs to ITW. The SS is for Stainless Steel Griddle. 900 series, 48 inches wide. Next everything goes to the ML number. Front or back drain, Electronic ignition, pilot light, gas valve design, safety system design, Thermostat, or thermostats, Even chimney vent can vary. Then you have towel bars and cutting boards.

What is it you are looking for?

And have you looked at the AGE or AGM series. (Wolf Branding). Or even the MSA model books

This is the 2019 revision service manual;. VH-MSA48_sm.pdf (static-pt.com)

and this is the latest parts manual; VH-Vulcan-900RX-MSA-Heavy-Duty-Gas-Griddle_pm.pdf (static-pt.com)

I want to caution you that this is for North American market. They were built for export as well, And will have been different with some electrical and Gas parts and specs.

<font face=”inherit”>Thanks for the reply. I </font>wasn’t<font face=”inherit”> so much expecting an exact manual as I was hoping to find alignment with what the unit I have has in it and what the Partstown manuals (948A for example) indicate. For example, my unit has 1 single solenoid gas valve for each burner and for each pilot, whereas the 948A manual directs to what appears to be a dual solenoid, which I assume serves each burner/pilot configuration? </font>

Interestingly there doesn’t appear to be an ML number. Just model and serial. However, I am going off of a picture I took of the plate and will have to have a look at the actual plate later.

I’m looking in general so that I can be prepared in the event of a parts failure. But specifically for the correct replacement solenoid. One or two of the solenoids on my unit are buzzing during operation however they do seem to be working as they should – burner comes on and off when thermostat is satisfied, etc.

I do plan on checking for any lose connections and to verify that the solenoid is getting 110V.

I will take a look at the two manuals you provided.

Thanks!

What parts are you looking for? What is different about yours?

Solenoid chatter is not good. It means that either the coil is not getting the design voltage, or the armature is unable to fully seat in the open position. Internal swelling of the coil, broken buffer stop, improperly mounted coil, or corrosion are all things I’ve seen. Low voltage will normally not pull in. That is when the current flow is highest. IT take very little to hold it in. Often I’ve found that someone replaced a coil, and either it was upside down or they put the spring washer for the top in the wrong place.
