Thanks guys. I'll take a picture of it when I get home tomorrow.

Need help with replacement intermittent pilot on Crown boiler

@ November 28, 2012 9:15 PM in Need help with replacement intermittent pilot on Crown boiler

I'm looking for a replacement intermittent ignition pilot assembly for our Crown boiler. I spoke with Crown on the phone and they gave me Crown part number 35-4700 and Honeywell part number Q348A1275 however neither is turning up any good results when I do a web search. I didn't see any markings on the existing pilot when I pulled it out last night to look at it.

I see that Pex Supply sells universal intermittent pilot assemblies which looks like what I need. The pictures on the website aren't the greatest but the batwing hood universal model looks like the closest match. Am I on the right track? I was hoping someone could help aim me in the right direction.

Macon and Honeywell TRV's for sale

@ October 24, 2012 11:05 AM in Macon and Honeywell TRV's for sale

(5) TRV's complete with thermostats. These are in good working condition and only have a couple days use on them. I purchased them to install on 2nd floor steam radiators to control the heat in bedrooms but I ended up going a different route, so now I'm left with (5) TRV's that are pretty much brand new which I have no use for.

(1) Macon MAOPSK (minus steam vent), sells for $134
(4) Honeywell 002042HSL10, sells for $56 each
(4) Honeywell T100M2056, sells for $36 each

Looking for $60 for the Macon OPSK, and $40 for each Honeywell TRV/T-stat combo.

Located in Worcester, MA. Can ship in USPS Flat Rate box for actual shipping cost.

Payback

@ February 15, 2012 1:40 PM in Is oil-fired boiler more effective for steam than gas-fired?

Yes, the payback is quick. Our oil fired boiler failed a couple years ago, thankfully in the early fall so we had the luxury of taking our time and investigating natural gas. The data we found suggested something like a 3-4yr payback if I remember correctly. Well after two seasons the savings has pretty much paid for the new system.

As an added bonus I got more floor space in my workshop by getting rid of the oil tank.  And also worth mentioning is how much quieter our gas boiler is. The old oil boiler with the Becket blower was friggn' obnoxious...

Think I might be on to something...

@ January 30, 2012 3:17 PM in Added Honeywell TRV's, now radiators are accumulating water

Ok, so after some more research it looks like this particular TRV lacks a vacuum break which is what could be causing the problem. So in order for these to work I'd have to add a vacuum break between the TRV and the radiator. Problem is I'm having trouble finding a suitable vacuum break (1/8" NPT).

Am I on the right track? If so, does anyone have a suggestion for a suitable vacuum break?

Seems I could have avoided this entire mess by going with Macon TRV's in the first place as they have an integrated vacuum break, but since I've invested over $300 into the Honeywell products I'd like to try to make them work.

Added Honeywell TRV's, now radiators are accumulating water

Hi Guys,
I have a two story house with a one pipe steam system. I've always had a problem with the second floor getting much warmer than the first floor so to alleviate this problem I purchased and installed Honeywell TRV's with temp sensors on (3) second floor radiators:

http://www.pexsupply.com/Honeywell-T100M2056-Integral-Temp-Sensing-and-Integral-Setpoint-for-V100-and-V2000-Series-Radiator-Valves?source=igodigital

These three radiators are approximately 25' feet horizontal, and 12' vertical from the boiler. All steam lines are pitched. Radiators are pitched as well.

The problem I'm having is these radiators are now accumulating water and spitting it from the vent. I never had this problem before I installed these vents so I feel this has to be due to poor venting. There are no main line vents anywhere on my system and it's always functioned fine without them, but perhaps these TRV's just aren't allowing enough ventilation?

Would it be advisable to drill/tap an 1/8" NPT into the supply pipe just before the radiator gate valve and install a main line vent before each radiator?
