I have been using my h4 for about 45 days here in ohio it has been down in the 30s at night and low 40s in the day well this morning I woke up from being cold furnace blower on so I went outside and the blower was in but no flame I had to relight it at 2am. I have not had any issues so far just wondering why it would go out after so long with cooler weather I am burning pine maple and cherry right now and have been doing so since the start. You guys have any opinions on why this would happen
-
Sounds like the fire burnt itself a hole and the wood didn't "fall "in..Wood was hung up..
-
Marty is probably right, it's called bridging
-
I never thought of that the wood was still piled in there almost like I had just put it in there but burnt. I am still new to this is there a reason this would happen I thought mabye had to much ash in the ash box so I cleaned it out its going now I hope its no big deal thanks for the input if there is any way to keep this from happening please let me know
-
How much difference do you have set on your aquastat?
-
The dealer set it at 164 on 174the off
-
You want to leave some of the coals in the ash pan. When the blower kicks on it will turn the caols bright red and create a lot of heat to get the fire going again. Is your wood seasoned really well? I can burn some wet stuff in mine but only if there is a high heat demand on the stove. The wet stuff will tend to go out.
-
alot of my wood i believe is seasoned cause i split it small and alotof it is pine and it doesnt weigh much but i believe next time i split wood if it will fit through the door i belive i wont split it, what size splits do you guys burn
-
I haven't burnt a lot of pine so I'm not really familiar with how it burns. I split a lot of my wood to about 6-8" around. When it gets cold, if it fits in the door I will burn it. I will always put some smaller logs around the big one though.
I don't know a whole lot about the H4's but just out of curiosity, do you have the holes on the flat steel that covers your blower? The one that the solenoid lifts up when your blower kicks on? Mine has two holes on it, one has a screw in it to regulate the air that goes into the boiler when the blower isn't running. Is one of the holes open?
-
yeah i have a screw in one of the holes like i said this is the only time this has happened plus me being new to burning wood i just thought i would ask thanks
-
okay, just thought I would ask. I have come home to my H2 being out before. I guess it just happens sometimes.
-
I have had the same problem. I splite some dry wood I have very small to built up some coals, and I took 2 of the screws out to give it more air at idle. I also bought a cap for the chiminey at rural king to keep the rain out.
-
I would like to buy a cap and possibly a couple of stack extensions
-
Well I woke up to a cool house this morning I figure its cause I am burning pine only. If I take the second screw out if the blower cover plate will my wood usage increase or not the lows at night have been in the low to mid 20s this is third time this has happened in roughly 60 days is it from burning pine as it doesn't leave many coals or not enough air on down time
-
I would think that your wood usage would go up if you took the other screw out. Does your pump run 24/7 or do you have it hooked up to only come on when the house calls for heat? Is your house insulated really well? I would think that with the temps being in the 20's that you would have plenty of heat load and that you wouldnt have any issues with the fire going out. I have never burned pine in mine so I don't know how it burns. You might try mixing it with some over hard woods. Is it seasoned well? I can burn wet hard wood in mine and it doesn't go out so I'm thinking it is from the Pine.
-
no my pump only runs when the house calls for heat as for the insulation i believe that it is good but my guess is the pine also cause it doesnt leave many coals. also the pine has been c/s/s since early this spring it weighs less than when i cut it
-
ok. I run my pump 24/7 on my setup. I don't have very well insulated lines and my house isn't insulated very well so it calls for heat more than normal.
I am guessing that I have a lot of heat loss in the lines so my owb probably cycles more than it should, so it never goes out.
Have you tried loading the wood to the very back of the stove so that it's closer to the blower? I really think that the pine is your issue though, maybe someone that has burnt pine will chime in soon.
Also, when I empty my ashes I make a little pile like right in the middle of the ash pan so that when the blower kicks on it blows right onto the ashes and they get bright red. Maybe try this?
What is your aquastat set at?
-
So for this season I have been burning mostly Hemlock but I also mix it with two or three pieces Red Oak. To date, I have had no problems and usually have a nice bed of coals by the time I get home from work.
Currently, I run my pump 24/7 which lets my furnace cycle more often. When winter sets in, I will change my pump to come on when the house calls for heat.
-
I'm a little confused....Was the wood bridged when you went outside or just burnt up?
I've never had a problem with bridging but I have used pine. If your using only pine
it burns a lot quicker than hardwood.
I use pine in my stove and haven't had problems with the fire going out. I have had
problems with the wood burning up and my fan will stay on blowing cold air into
my firebox cooling the water temp.
I installed a timer on my blower. I pack my stove (2) times a day and set the timer for
8hrs. The timer is setup to power the Aquastat. The Aquastat will work normally cutting
the fan on and off until the timer has ran out of time.
-
the wood wasnt bridged it just burnt out i usually load it in the evening and i leave both the ash door and the main door open and get the fire really going but last night the blower was on so i just loaded and walked in the house no big deal just curious. i have hardwood just wanted to burn the pine up since i have acess to a bunch of it and other than the few times it went out it does great
-
I have had same problem in past, started mixing the pine with hard wood , seldom have fire to go out anymore.
-
Here is my opinion, after having used a Hardy for 14 years. You said the wood was still sitting there just like you put it in there. right?
Pine burns hot and fast, so I think it heated the water up so fast it shut the blower down before any coals could form. The water stayed hot long enough that the fire went completely out before the fan kicked back on. As others have mentioned you need a bed of coals all the time.
I don't know about the pine you have, but Missouri pine is not going to give you that. I burn a little of everything but I always make sure I have enough seasoned oak or hickory mixed in. to keep that bed of coals.
I also don't clean my ash pan completely out, I make sure the ashes stay below the grates, and leave ashes along the edges on top of the grates.

I took both screws out of the blower cover and seems to be fine for now and that's what my friend does plus he has a paper clip under it also. I dint notice any difference in burn time either

i would question why you had to do this? The stove was not made to operate this way when built and i am going to guess this stove did not operate this way in the past?
you say you now have taken the cover off so there is no longer any restiction on how air gets into the stove through the blower? if this is correct i am unsure why you dont have a runaway fire to the point of overflow (boil)
have you looked at the air passage between the fan and where the air enters the stove? (perhaps there is creosete buildup partially blocking the passage?) having to change the way a stove was built to get it to burn seems quite strange to me
-
There are two breather holes in the plate the covers the blower it had one open and one plugged I took both screws out to allow just a bit more air while on idle. The blower cover is still there if I think about it ill post a pic so you can see hope I didn't offend you by the way I explained it this is all new to me mabye that's why I am having the troubles lol
-
you havent offended me, ii just did not understand teh removal of the screws, i thought that meant you removed teh cover completely (my misunderstanding)
