OEM parts available

@ May 3, 2014 8:12 AM in Repair vs repaired rate.

This problem does occur when local reps refuse to carry replacement parts. It should not be the contractors responsibility to stock these items. It is time that the manufacturers reps increase there inventory and eliminate this problem. I can't tell you how many times over the years a rep has told me that we will have to order the part from the factory and is your customer willing to pay for overnight shipping. My feelings are if you are going to be a rep than be a rep. Don't provide excuses rather results. This way everyone will have a good day, especially the homeowner.

I came across a Trane cast iron boiler which appears to be a re-brand of an Italian Ferroli boiler. All the controls are EuroHoneywell. The gas supply line is gasketed going into the gas valve. It is my understanding Trane no longer sells these boilers. I contacted Ferroli in Italy and they stated they do not have a USA distributor. I asked Trane if they kept parts locally and they stated that they do not.
It is a sad day when a customer has to replace the boiler because there is no parts available in a crisis situation.
I am still trying to find some components to have on hand when this unit fails.
We have a responsibility as ethical contractors not to sell products which are not supported locally. I suspect that the contractor who sold this boiler never considered this possibility.

RP340 vs Milwaukee

@ October 25, 2013 9:03 AM in Press Tools - Ridgid vs Milwaukee

I have become very bias with regard to press technology. I used a Ridgid 330B for six years and have pressed everything from 1/2"-4" and have not broken a jaw or had a leak. Furthermore more recently I have begun utilizing Mega Press for gas distribution and it is exceeding our expectations with regards to time savings and performance. To summarize ! as for me I will stick with a proven track record. I recently ordered the new 340 tool.
Keep on pressing !

RbI whining boiler

@ December 4, 2012 11:35 PM in Whining RBI 600 Dominator

Thanks for the info Mark. I think you nailed the problem diagnosing buildup inside the tubes. I feel that after 15 months some type of film or scale has bonded and is causing localized flashing. What are your thoughts on valveing off the boiler and circulating a cleaner through the HX and then flushing. Would it be better to go after the entire system?

I have a copper boiler that has been in place for fifteen months . It provides both space heat as well as domestic hot water by way of a turbo max. The system is piped p/s through a low loss header. The gas pressures are correct and the flow rate is 20 degrees delta T across the heat exchanger at high fire. The system has not made up any water to speak of. The building is approx. twenty feet high to the top of the radiation. The system pressure is 18-20 PSI. Two weeks ago the boiler began to whine as it approached the set point of 175 degrees. The system did not appear to be dirty when the equipment was replaced. Why would this problem start now? I would appreciate any help

Lochinvar KBN 106 noise

@ October 9, 2012 9:23 PM in Lochinvar KBN 106 noise

I was contacted by a homeowner who has had a lot of banging in his system. The system pressure in within normal limits 12# and all combustion values are good. I heard the noise and isolated the system. I removed the top on the spiro vent as well as the screen and found small pieces of a nylon,Teflon, polymer or plastic material restricting flow. After cleaning it seemed to quiet down but not totally. I attempted to close the webstone flange isolation valves on the boiler pump and they would not move. I am wondering if these valves have failed and perhaps have lodged similar material in the heat exchanger reducing flow therefore causing the banging. Has anyone ever experienced a ball valve disintegrate and cause problems of this nature? I know that the pump is working properly and the right size. Is there an effective way to flush foreign matter from a gianonni heat exchanger?

Stiffening bracket

@ October 9, 2012 8:11 PM in Lochinvar knight boiler noise

The bracket fits inside the cabinet and tightens across the top of the heat exchanger. Give tech service a call at Lochinvar 1-800-722-2101 and they should be able to help you with this

Permeates anti seize

@ September 16, 2012 7:52 PM in Giannoni thread size

Thank's for the info . Given the heat generated around the heat exchangers on these mod-con boilers I am going to apply permatex to every thread.I have had enough of a scare. With the fine metric threads and the heat. I will add that to my tool bag .

Thank's for the info, I was able to determine that the thread size is an M6-1 that is a metric size 6 and 1thread per milliliter. I found a store that specializes in metric nuts & bolts.I also purchased a hex die which I can chase the threads with. I have found that several of these heat exchangers have some ragged threads which could cause a cross threading event. I also purchased some M6 stainless flange nuts. these are also handy to have on the truck in case some are lost.

@ September 11, 2012 8:22 AM in Giannoni thread size

I was trying to find out what the Metric bolt size was for the Giannoni heat exchanger. I am referring to the stainless studs that surround the front opening where the front burner plate connects. I have serviced some wher the threads have been damaged and has made it difficult to tighten the nuts. I thought that if I had a hex die in my tool kit when servicing, i could dress the threads if there were a problem.
