Temperature Controlled Burners, Brutus, Banjo BG14, Piloted Honeywell Valve Questions
 
I'm building a Brutus 10 style single tier stand with an automated HLT and direct fired MT setup. I have some questions about the gas lines. First off, I'm using BG-14 LP Banjo burners converted to low pressure. I'd like to have valve-integrated standing pilots with safety valves on the HLT and MT only (I'll light my boiler with a manual spark ignition).

I've been searching and reading through the forum to find all of the parts I'll need for this. I liked the one-stop kit nature of the Y8610U setup (see this thread for more on that), but if I read it right, that would mean over $230 per burner which seems excessive. It does have the added benefit of a "controller" to initiate a reignition sequence, but I don't need all that. For me, if a strong wind blows out my pilot I want the pilot and burner valves to shutoff, that's it.

Here's the list of gas parts that I think I need for each automated burner (I'm not including the liquid-side PID, etc). To all you experts, does this look right? (Sawdustguy, kladue, and others come to mind):

66.32 Honeywell VR8200A2132 Link
5.40 LP Orifice 390686-1 Link
5.65 Natural Gas To LP Conversion Kit Link
3.95 24" Thermocouple Link
15.95 Honeywell Q314A4586 Pilot Burner Link
------
97.27 Total

[Prices may vary]

Thanks for looking! Your comments and suggestions are much appreciated.

Anyone want to sanity check this parts list?

The part list and prices look right, you do not normally need the Orifice for the pilot or the LP conversion spring for the valve as it usually is included. A 75Va 24 volt transformer should complete the needed parts for a dual valve setup. You might check PEX supply for valve price and see if a combined order would save some on shipping and handling.

Thanks kladue. I assumed that the valve came with a NG orifice which needed to be swapped out for the LP version. Are you saying that the orifice and the spring that come with it will work fine with LP?

I hope not, cuz I just spent $25 to have 3 of those orifices delivered.

Wow I didn't see this before but apparently the conversion kit comes with it:

"Includes: Natural to LP Conversion Kit, One 1/2" x 3/8" reducer bushing, One 3/4" straight flange"

At the bottom of this page.

EDIT:

The pilot burner also comes with the needed conversion orifice:

"Includes: 1/4 in. CC INLET FITTING. SPECIAL MOUNTING BRACKET WITH SCREWS FOR CONVERTING "B" BRACKET TO "A". and LP Orifice"

Which is at the bottom of this page.

Normally the pilot comes bagged with the LP orifice, and usually the gas valve has a spring and cap for change over to LP operation. Just remove old spring and cap and replace spring with heavier spring and new cap from package.

Ahh, well since I didn't get the conversion kits I guess I'll still need them :D. I bught a 3rd in case I ever need another and don't want to pay $10 'handling' for a $5 part. It's impossible to find anything for propane in my neck of the woods. It's all natural gas or fuel oil in these parts.

I'm looking around for one of these now. Do I really need a 75Va? Seems a bit high maybe.

Can I get away with a single 24 volt 40Va transformer to power both honeywell valves (VR8200A2132) ?

Transformer ratings are new to me, but if I'm calculating this correctly, based on what I've read the transformer size should be:
volts x load current x 125% (for startup factor)
or for each valve:
24V x .3A x 1.25 = 9Va
So I'm figuring 2 valves would be 18Va, making a 40Va transformer plenty, right?

Thoughts?
