@ October 13, 2013 10:17 AM in Really bad installIs this boiler atmospheric, if so why barometric damper, it looks like the horizontal flue is not pitched upward could just be the angle of the picture
@ October 11, 2013 10:22 AM in wall furnace flame recirculationDoes he mean flame roll-out which could be caused by a blocked, damaged or incorrectly installed flue, does the heater have a fan? could the heat exchanger be cracked ? which would require replacement of heater
@ October 11, 2013 10:11 AM in amtrol model 30expansion tankdiaphram or commercial bladder style tanks, always make sure the air charge is correct before allowing water into tank, should match system press.
@ October 10, 2013 3:18 PM in broken cap on steam valvesIf you can find the same brand valve you can loosen the bonnet on the old valve, remove the disc and stem assy. and replace it with disc stem and handle from new valve. Or just replace the valve. I dont recommend this as a homeowner type job
@ October 8, 2013 10:20 AM in firetube vs. watertube boilerscan you be more specific on the boilers you are talking about

@ October 2, 2013 11:13 PM in Radiator Valves: Full Port?All the supply houses I would deal with (Cal Steam, Ferguson, Pace supply ) had no problem letting me take valves and fittings to a job as long as I returned them the next day no restocking charge, I am not in favor of import valves but sometimes the dimensions would fit a problem radiator job
@ October 2, 2013 10:22 AM in Radiator Valves: Full Port?Hoffman or Hammond, used either or on 1 pipe steam for years, dont get to hung up on this full port thing get 1 of each brand and see how they match to your old rad. return the 1 that you dont need.
@ September 28, 2013 7:44 PM in Dirty Steam Water in Hot water tankDo you have a backflow preventer on the boiler. have you had water line repairs in the area
@ September 28, 2013 7:29 PM in Pneumatic controlsworked on them for yrs. pneumatic contols were usually used in commercial applications
@ September 25, 2013 9:53 PM in How to find a leakCheck the relief valve , some times hard to see if its leaking if its piped into another drain line
@ September 25, 2013 9:47 PM in ac system design helpavailable online Bookmark Inc 1-800-642-1288, or check your local Trane supply house $40.00, well worth it
@ September 21, 2013 10:29 AM in Help: Leaking Drain Pipe On Side Of FurnaceI agree with all, you should also clean drain pan, there are products available to put into the pan to lesson future clogging ( pan pills ). Check the equip. install instruct. and see if this equip requires a trap
@ September 19, 2013 2:47 PM in ac system design helpI would find someone with a background in ductwork to help. Get a Trane Ductulator, the Trane air conditioning manual ( hard back book ) and fan curves on your equip. to get started

@ September 17, 2013 11:29 AM in It's that time again!Working in San Fran for 20 yrs I remember that part of September and October were the only months you could shut down boilers for more than a week. In July 2011 it never got above 60 degrees the whole month. But starting my career in Denver yrs ago I know what you mean, I always loved the smell of an old boiler room when firing up the boiler in the fall.
@ September 15, 2013 1:14 PM in dont forget that towerAs we approach fall dont forget to schedule a cooling tower shut down and drain of the smaller towers. I remember a job in Denver years ago when we forgot to check a tower, we were counting on a auto drain system (3 way zone valve ) that failed. Got a call from the customer that something did not look right on the tower, , thats when we found the tower and pump froze, the tower looked like a beer can left in a freezer,and the pump volute was cracked. lesson learned
@ September 15, 2013 10:19 AM in Pilot questionIn my years of working on gas fired equip, mostly commercial, I have found most pilots (Honeywell, Johnson controls ) come with a natural gas orfice and a smaller diameter propane orfice. Larger systems use pilots made for there equip. incorpoating either flame rods or U.V scanners
@ September 13, 2013 4:00 PM in Condensate meterThe Old Spence amd hoffman press. reducing valves required a set horizontal pipe length coming off the outlet piping as well as the pilot piping, If the piping run was to short the valve may hunt and have a hard time maintaining lower outlet pressures.
@ September 12, 2013 10:24 AM in SYSTEM PRESSURE --need assistance,Sounds like the good old systems , compression tanks allowed somewhere for the air to go, what do you mean by self bleeders, if they are auto air vents they should be valved off after initial fill of system
@ September 11, 2013 6:29 PM in What happened to all the solar thermal systems from 30-40 years ago?I remember back in the mid 1970s congress passed the energy tax act which allowed home owners a 40% or more tax credit on solar system installs and additional 15% on insulating , not sure what tax credit was allowed for commercial installs, this created an overnight appearance of solar companys, some legitimate some with non tested systems, the better systems still had the problem of storage when there was no sun. When President Reagan took office in the 1980s the tax act was dissolved. I remember solar companies going out of buisness with in days. The fact that some of these systems were never proven and that the life span of alot of solar hw panels is between 25-30 yrs may be the reason some of these old systems are being abandoned
