That makes sense. I have 2 thermostats in the house, one is the normal one for the furnace and the other is below it and just runs the fan in the furnace. Right now I am solely running off the furnace, I could put a 1 or 2 degree differential between the 2? I was just trying to make sure the boiler stays at set temps.windyhill4.2 wrote:The reason it is going into idle fire is that there are not enough demands for heat. Cutting the feed back will only require more from your propain unit. Leave the coal boiler settings alone,cut the propain back a bit & leave the coal boiler work more.

If you have the propain t-stat set just a bit below the coal t-stat,the propain should kick in b4 the coal boiler drops terribly far.This would aid the coal boiler in it's recovery.

I thought we could have a movie night which might help you guys get a better visual of what's going on. This first vid is how I have been running last couple days. This is about the max I can run the fire with both stokers. I know the grate is not full and this was done purposely to try and get a complete burn and lower consumption while I have been running with the propane furnace.

This next vid is me messing around tonight. This is lowest fire to keep fire on one stoker and max burn on the other. I actually had to close the blower gate some more as I lost more draft as the fire got hotter. This is what I have been talking about with my expectations should be with both stokers running. Again, the fire has not totally settled yet so I know the fire on grate may need to be tuned.

This video is just to show what I'm seeing on the manometer at fire box and breech. This is as hard as I can run the stokers and still have a draft to prevent pressurizing the fire box. The reason I messed around with running one side hard as I talked with the other boiler owner on here and he is having the same issues as me but he is running a chimney. He said his seemed to run better running one side at max fire then both sides at what I think is less than max. I left one side running as low as I could to stay lit because it's a pain to re-light. Not sure if I'm right or wrong but just thought videos might help you guys see what I'm seeing.

My opinion,for what little it may be worth... is that you should get it firing properly at the maximum possible & then.... only after that .. then worry about consumption. BUT, my main priority in life during cold weather is to get warm and stay warm.... consumption is just the cost of being warm.If I had consumption at the top of my priority, I would keep the pipes from freezing by electric tapes & insulation,only heat 1 small room & wear insulated clothing all the time. BUT, I LIKE being warm,consumption will not be my top priority.

I think the videos help.
Can you take a nice long video showing us around the boiler? Go slow showing us around. Also Show us the heat exchanger , and modine connections.

Exactly windy, this is the best I can get it to burn without pressurizing the fire box. This unit is rated higher than yours I believe, is your fire bigger than this?windyhill4.2 wrote:My opinion,for what little it may be worth... is that you should get it firing properly at the maximum possible & then.... only after that .. then worry about consumption.

Are the pipes under the garage & over the garage insulated ? The pipes I saw looked like they were not insulated.

swyman,i noticed that your hopper lid was not on,is that not required on that unit ? I do know that many stokers on this forum have issues if the unit is operated without the hopper lid.
