wall furnace

@ October 13, 2013 12:52 PM in wall furnace flame recirculation

Call the company that supplies your gas    In a lot of areas they will check your heater free of charge,  and I always recommend a good CO detector in all rooms

install

@ October 13, 2013 10:17 AM in Really bad install

Is 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

heater

@ October 11, 2013 10:22 AM in wall furnace flame recirculation

Does 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

tank

@ October 11, 2013 10:11 AM in amtrol model 30expansion tank

diaphram or commercial bladder style tanks, always make sure the air charge is correct before allowing water into tank,  should match system press.

valve

@ October 10, 2013 3:18 PM in broken cap on steam valves

 If 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

boilers

@ October 8, 2013 10:20 AM in firetube vs. watertube boilers

can you be more specific on the boilers you are talking about

relay

@ October 4, 2013 2:51 PM in HoneyWell 8043G Zone Valve Question

Use a honeywell R845A 1030 relay package

valves

@ 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

valves

@ 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.

dirty water

@ September 28, 2013 7:44 PM in Dirty Steam Water in Hot water tank

Do you have a backflow preventer on the boiler.  have you had water line repairs in the area

controls

@ September 28, 2013 7:29 PM in Pneumatic controls

worked on them for yrs.  pneumatic contols were usually used in commercial applications  

dripping

@ September 26, 2013 9:53 AM in How to find a leak

Is'nt the condensate from the flue gas

leak

@ September 25, 2013 9:53 PM in How to find a leak

Check the relief valve ,  some times hard to see if its leaking if its piped into another drain line

book

@ September 25, 2013 9:47 PM in ac system design help

available online  Bookmark Inc   1-800-642-1288, or check your local Trane supply house  $40.00,  well worth it

drain

@ September 21, 2013 10:29 AM in Help: Leaking Drain Pipe On Side Of Furnace

I 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

sizing

@ September 19, 2013 2:47 PM in ac system design help

I 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

compressor

@ September 17, 2013 11:33 AM in Heat Pump Compressor Diagnosis - Building Fire

The internal overload may have been compromised

boiler

@ 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.

dont forget that tower

@ September 15, 2013 1:14 PM in dont forget that tower

As 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

pilot

@ September 15, 2013 10:19 AM in Pilot question

In 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

steam valve

@ September 13, 2013 4:00 PM in Condensate meter

The 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.

pressure

@ 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
