Bypass the OD reset

@ November 4, 2013 1:31 PM in How can we temporarily bypass a Burnham IQ outdoor reset?

Yes jumping terminals #&$ on the card will simulate and call for DHW and override the t-stat demand. The control also has priority built into it so the heat circulator will shut down.
Are they using deep night set back? If so reduce the degree of setback. How many zones? Maybe change the boost time on the ODR card.

Sq ft

@ October 23, 2013 10:16 PM in EDR

3.4 sq ft pes lineal ft.

Short cycling

@ September 29, 2013 9:44 PM in First high efficiency boiler on my own...short cycling! Help!

At some point our industry will learn to do heat loss' for every job. Nothing works better or saves more fuel than properly sized or slightly smaller due to multiple zone boilers.
The Alpine can be de-rated both for heat and DHW, also can slow down or speed up the modulation rate, differential above and even the light-off rate to reduce input in the first 10 seconds.
One stat and cast iron radiation should be able to work this out. I would not add anything for the indirect unless big hot water demand.

MPO-IQ

@ September 9, 2013 9:59 PM in Searching for Oil Boiler

The easy add option cards for LWCO and ODR are a plus, pre-purge on he circulator, self troubleshooting etc.
I also agree that 3000 sq ft @ 100k loss is high. I would suspect more like 60 - 70K. 

Burnham Alliance Stone Lined

@ September 9, 2013 9:49 PM in stainless vs stone lined on long island(Mr O' Brien)

No anode, not required. Water conditions will not affect these tanks, also replaceable coils if needed down the road.
I have installed many with absolutely no problems.

Shut off fill valve

@ August 23, 2013 8:07 PM in Boiler at Minnesota daycare explodes

Not sure if they still do it but B&G stated in their manual for auto-fill valves to close the manual vale prior to the auto-fill when the system is filled and purged.

I wonder

@ August 7, 2013 8:12 AM in Giannoni HX?

What percentage, fact not opionions, of the worlds Stainless heat exchangers are made by Giannoni?

Boiler bypass?

@ August 2, 2013 5:12 PM in Boiler cleaning? Blaa! Who needs it?!

A boiler bypass will allow much of the return water to bypass the boiler and go back to the supply therefor bypassing the boiler. Reducing the flow in the boiler mill allow cooler water to enter the boiler and reduce condensation.
Many try to do this with a system bypass that takes hot supply to cold return which is the opposite of what should be done on residential boilers. When boilers had larger water volume a system bypass was a good thing.
Today with much less water volume in the cast iron boilers we need to reduce the flow into the boiler to get the water temperature up quicker. To quote the late great Gil Carlson " thermal stress and condensation is a result of extremely cold water entering the boiler or coo water at a high flow rate." While we cannot control the temperature with a system bypass we certainly can control he flow rate with a boiler bypass. Adjust the flow to a 20f - 40f delta-t in the boiler and things will work fairly well. Hydronic s Institute states that a boiler bypass sytm will usually give ou 3 times the low in the system than through the boiler. Been using the boiler bypass for years with no boiler issues.

Pipe size

@ July 26, 2013 10:10 AM in circulators/pumps

Now I am confused. Pipe size has to affect gpm. If I use smaller pipe the velocity changes which in itself will not affect flow, agreed.
If velocity increases so does resistance to flow ( head), does that not affect gpm flow?

LWCO

@ July 11, 2013 9:08 PM in Best Location ModCon Low Water-

In PA it must be above the heat exchanger and not more than 18" above the het exchanger.

Chair

@ June 15, 2013 10:57 PM in I want one of these!

I'd run chilled wter for summer and warm water for winter.

Steam to water

@ June 6, 2013 8:21 PM in Radiator - can I use for FHW?

Western Pa has done many many steam to water conversions with virtually zero problems. I am not saying it was financially a good decision but they were one successfully. The rep estimates over one hundred.

Selling in China

@ June 6, 2013 8:08 PM in Buy American

They were one of the few boiler manufacturers to sell there product in China. Not sure they still are or not. I remember seeing the chinese literature. actually remember Russian literature but i know that stopped due o Russian economy. Maybe it was part of the deal. Scratch my back I'll scratch yours kinda deal.
You never know what goes with the deals.

Indirect s

@ May 18, 2013 10:07 AM in Longest lasting indirects

I have super-stor & Vaughn stone lined tanks in excess of 20 years. I have many Burnham Alliance tanks (Vaughn) with not one issue but only about 6 years to present. I switched to them due to local water quality in a certain area with lots of farms. I was losing stainless steel tanks in a few to 5 years.

Supports

@ May 16, 2013 2:19 PM in Hey all, looking for old cast iron feet supports

Also sold by Burnham

Burnham Alpine

@ May 10, 2013 4:45 PM in Burnham has a sense of humor!

I saw a newer piece where that was straightened out. Probably a marketing error. They are saying radiant heat and large wter volume systems are a good application. Guess someone caught it.

Us boiler

@ May 10, 2013 4:18 PM in Polypropylene vents becoming the way to go

If you remember Burnham was trying to stick to their guns stating the same thing 5 or 6 years ago but caved in. Now we are starting to see it happening. I heard a rumor of about three states considering a look at stopping PVC venting. Not sure they will or not.

Close spaced tees

@ May 10, 2013 4:12 PM in Primary Secondary Problem

I thought the spacing before and after the tees is important. I read somewhere the distance before should be a minimum of 8 pipe diameters and 4 pipe diameters after the tees.

DHW

@ April 22, 2013 9:31 AM in Burnham Megasteam sizing

You can add an Indirect water heater tot he Megasteam. There are control and pipe tapings(tapings K & L) for doing just that on the boiler.
Avoid the domestic hot water coiler. very expensive way to make hot water as the boiler maintains temperature all the time.
The boiler is cold start and only runs in the summer for a call for hot water.

ES2and Burnham Alliance

@ April 18, 2013 9:25 PM in Pros / Cons of Indirect Water Heater

I have used these together with much success. I have also used the Burnham Series 3 with the Alliance with no problems. Just size them correctly.

DHW coil?

@ April 18, 2013 9:05 PM in Burnham Megasteam sizing

Forget that idea. It is the most expensive way o make hot water. Use n IWH as it can pipe into the boiler.

Conversion

@ April 1, 2013 3:24 PM in Steam experts/contractors in lower Westchester NY for gas burner install on oil steam boiler

The v8 is not suggested to be converted to gas if you look at the installation manual.
