@ March 4, 2014 2:13 PM in Pressure keeps tripping relief valveThere are a few things that could be causing the relief valve to pop. The pressure reducing valve may not be sealed tight and could be letting water slowly into the system. Where does the domestic water come from? Does it come from the boiler or is there a separate hot water heater or storage tank? If there is an internal coil there may be a small hole in that as well causing the pressure to rise.
@ February 26, 2014 8:48 AM in High heating bills - looking for some ideas!I would be very concerned about seeing any steam exiting your exhaust. It could suggest a crack in the boiler above the water line. Is there an automatic water feeder on this boiler?
@ February 9, 2014 9:42 AM in burnham gas fired boilerIt's very likely that the low water cutoff is incorrectly telling the water feeder to add more water to the boiler. Do you have an internal probe low water cutoff, or an external float low water cutoff? How old is the boiler?
@ January 26, 2014 5:39 PM in Is there a leak in my heating system?Keep the boiler pressure up around 20 PSI while you go around the house and bleed each radiator. The boiler feed valve is likely factory set for 12 PSI so you will have to lift the manual lever to get the desired pressure. After you bleed the last radiator make sure the boiler is around 18-20 PSI and then check the gauge every so often to see if you are losing any pressure.
@ January 23, 2014 8:11 PM in Steam radiators leaking waterWhere exactly is the water coming out of the radiators and how often are you manually filling the boiler?
@ December 28, 2013 7:17 PM in Oil burner relayYes, it's possible for the cad cell to be bad without any visual imperfections but it's also possible the R8184D control is bad also. If it ignited and went out around a minute, it sounds like the control didn't pick up the signal for flame which indicates either a bad control or cad cell eye and wire.
@ December 28, 2013 6:28 PM in Oil burner relayWhen you first pushed the reset button and it only ran for a minute, did the burner ignite? If it did, then I think you can pretty much narrow your problem down to the control or cad cell. If it didn't ignite then there are many other things that could possibly be wrong why it keeps locking out like a plugged oil filter or pump strainer.
@ December 17, 2013 12:32 PM in Old steam system - no water in glass sight?That big black thing is your low water cut off switch and is VERY important that is working correctly. After months of neglect they tend to plug up very easily. Make sure that both valves on the top and bottom of the glass gauge are open.
@ December 8, 2013 7:50 PM in Still no heat after replacing Taco PumpHow did you come to the conclusion the circulator pump was bad? Is there isolation valves or did you have to drain the zone?
@ December 4, 2013 1:31 PM in too much heat 2nd floor!How long ago did someone replace the guts to the zone valve? The problem could be as simple as the manual lever is activated.
@ December 2, 2013 11:02 PM in Hidden steam leak between floorsDo you have an automatic water feeder on your boiler? I would keep a close eye on the water level in the boiler before cutting anything open.
@ November 24, 2013 8:47 PM in Intermittent to Interrupted ConversionPut a Carlin 60200 control in.
@ November 20, 2013 2:59 PM in Problem heating second levelHow long has this problem been going on for? Water temperature could most certainly be an issue. What kind of thermostat do you have in the bedroom? An old T87 mercury thermostat or a new digital one?
@ November 13, 2013 1:27 PM in Strange set up need helpYou will need to remove the 2" scully fill adapter, and in it's place I would put a 2" x 3/4" bushing with a 3/4" boiler drain valve so you can attach a hose to drain the fill pipe.
@ November 7, 2013 1:55 PM in water feeder & low watere cutoffWhen you press the test button on the PS-802, a dull yellow light indicates there is enough water in the boiler, a bright yellow light indicates that the probe may need cleaning.
If you haven't already before this season I would drain some enough water out of the boiler (while the water is cold) and test both LWCOs to make sure they are both operating correctly. While you have the boiler drained down it wouldn't be a bad idea to take the probe out and clean and rinse it off. Do not use Teflon tape when you re-install the probe. How old is the PS-802 probe feeder?
@ November 7, 2013 1:29 PM in Baseboards not getting hotAdding to Alan's questions, is there a vent on the baseboard to bleed air?
@ November 6, 2013 12:50 PM in water feeder & low watere cutoffThere is always power to the H terminal on the water feeder. On a 24v water feeder it should come directly from the transformer. That is so the manual water feed button will operate when you press it in.
I completely misread your post and thought you only had a M/M 67 LWCO. What model internal probe LWCO do you have? Does each LWCO send a wire to the water feeder "W" terminal? I've yet to personally come across a setup like this. Pics would be great.
When the water was originally low when you pressed in the manual feed, was the yellow low water light on?
@ November 3, 2013 5:53 PM in Hydrolevel VXT-24 OR VXT-120 Automatic Water Feeder for Steam BoilersIf you have to add water daily then there is a pretty decent sized leak. If you don't feel comfortable over-filling the boiler, then you can instead once the boiler has made steam pressure look in the draft regulator to see if you see any steam going up the chimney. This will also tell you if you have a crack in the boiler above the waterline. Otherwise check all of your piping and vents in the basement, and all of your radiators in the house for any sights of steam. You must locate all the steam leaks before doing anything else.
@ November 3, 2013 7:48 AM in water feeder & low watere cutoffDisconnect the wire that goes to the W terminal on the water feeder. If the water feeder continues to operate then the problem is isolated to the feeder. That wire from the W terminal is connected to the #4 terminal on the 67 LWCO. The #4 should only be powered when the water level is low and the float inside the LWCO drops. When the boiler has enough water in it, the float is up and the switch powers the #1 (burner) terminal.
@ October 31, 2013 11:26 AM in water feeder & low watere cutoffWas the water level low enough to activate the LWCO and shut the boiler off? You would have to test voltage to see if the LWCO is sending power to the to the water feeder. If it's not, it's likely the manual water feed switch got stuck after you pressed it.
@ October 24, 2013 3:37 PM in Domestic Hot WaterIt really makes no difference. Personally, if you aren't going to use it anymore I'd just open up the DHW relief valve to take the pressure out of the coil. You don't have to worry about completely draining the coil. How did they pipe the new gas hot water heater? Did they use a tee so the steam boiler coil could be used as a DHW backup in case anything ever happened with the hot water heater?
Also, there should be an aquastat on the steam boiler near the coil that would maintain temperature for DHW. Make sure those wires are disconnected so the boiler doesn't run on those warm days you don't need the heat.
@ October 24, 2013 3:10 PM in Domestic Hot WaterShutting off the domestic hot water to the boiler won't have any effect on your heat. Just make sure that you can see the water line in the sight glass, and if you know how to then check the safety on your low water cut off.
