bearings

@ November 4, 2013 11:25 AM in blower assembly

ball bearing and set collar      start by checking new parts make sure shaft is straight and there are keyways or flat sots in shaft. Sand and put rust dissolver on shaft by bearings, cut shaft and remove old wheels, install new wheels , slide shaft through wheels  dont forget set collars which I like on inside of bearings , you can move shaft back and forth to install bearings,   bearings are removed and instlled in bracket by turning 90 degrees,   tighten blower wheels on shaft, reinstall blower pulley

heater

@ October 30, 2013 1:14 PM in InfraRed radiant shop heater - need help !

I recommend you have a hvac contractor look at it   could be gas press. defective element.  Remember unvented radiant heaters require a minimum of 4 cfm of fresh air per 1000 btus, either mechanical or gravity per code

air

@ October 29, 2013 8:11 PM in baseboard stays cold

When bleeding air from a system which can travel throughout the system you need to keep system press. up, this may require partially opening fast fill valve if you have one or introducing another water source other than the prv. As far as the piping  the pump is a ( differential machine ) if your piping is not installed or balanced correctly your pump cant cause a differential and a no or per flow condition will exist

@ October 29, 2013 2:28 PM in baseboard stays cold

If the system worked before you may have some air in system, any time work is done on hydronic systems air will get back in system after refilling,  are you bleeding at highest point and for how long, are you bleeding with pump off, do you have purge valves for zones

shut off valves will allow isolation of individual radiators for any future repairs,  proper piping practice used by steamfitters for decades,  some balancing valves,circut setters are not 100% shutoff.   I worked in the Bay Area for 20 yrs,  If you dont already have a contractor call RMA   Redwood Mechanical or ABCO Mechanical

 Direct return      Make sure you install positive shut off valves on supply and return on each radiator as well as your balancing valve and drain and purge valves or air vents at high points,  these valves will help you when filling and draining system.  some prefer balancing valves on the return of the radiator,  ball valves not recommended for balancing, use a good quality balance valve that has gauge ports for installing a balance meter or gauges.   Bell&Gosset, Taco or Victaulic make good valves

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

can 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 tank

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