Electronics / second thermostat won't run blower fan on oil furnace

« on: October 31, 2019, 07:00:38 PM »

I have my OWB installed, Everything works just as it should with the exception of the fan in my oil furnace wont come on with the second thermostat.  I have read 30+ posts from all different OWB websites. Lots of info out there, I have tried many different things to get it to run the fan.  Right now the only way i can turn on the fan with the second thermostat is to take the face off the thermostat and jump a wire from W to RC.  I ran a jumper back up to G on first thermostat and fan only works on first thermostat.  Is this because I have a delay on the fan for the oil furnace? is it waiting for heat build up?  I am currently burning a Hardy H4 i picked up used, aquastat controls the furnace and i run my pump all the time to keep hot water flowing. Any help would be great.  Thanks Paul

Hardy / looking at a lightly used H-4

« on: February 13, 2016, 06:09:54 AM »

hello all, I am green here and looking at a hardy H-4.  its used and was professionally removed from where it was sitting and replaced with propane due to traveling keeping home owner away.  I went and looked at this thing yesterday, its big. My uncle and several of his neighbors have hardy stoves most of which have been in service 12 years or more.  My uncle told me to pressure test the unit before buying it.  I purchased fittings to pressurize this thing and want to know if its possible, i know that a leak is a bad thing.  second question, this thing has two pumps, does it run both pumps off of one tank? third question is how do you hook up the line for the water heater, that line is different and does not come from the 130 gallon tank?  the main tank used for heating just keeps reusing the same water over and over doesn't it? Couple of things my uncle has an H-2, thats really my only experience with these things but i really like his. No one has really been able to explain how this thing works, i have read Hardys PDF file, and there sales pamplet.  Oh this is a H-4 made in 2009, and it was unhooked last november, and drained.  Last question the condensor tank top, it will hold pressure without damage?  I did notice the 6 ash grates were slightly warped, not sure if it came that way or the ashes were not emptied when they should have been.  OK let me have it, pictures would be great, help me understand this stove and what i am looking at.
