260 coal gun up and running!!

BodyshopPat · Post by **BodyshopPat** » Sun. Dec. 23, 2018 8:52 pm

I have the 260 coal gun up and running as of this afternoon, its been burning about 5 hrs and has not ashed,,

I am a little concerned about this, my manual covers the Fuji controls and I have the love controls
I set everything as per the email that ahs sent me, I have the low number at 130 but the upper number the pv I cant find out what that number is or what is should be reading,, I feel the bottom of the unit is very hot and the ashpan is so hot I cant touch the handle,, I wondered if anyone on here knowing what I should be seeing could give me a phone call ,,, 304 719 2657 hate to shut it down since I just got my water all warm and everything,,, any help will be appreciated,,, Pat that upper number is hovering around 250 to 300

they also sent me instructions that were not too clear about rewiring the grate switch, i did that but have since put it back like factory to see if it would ash below are a couple of pictures, excuse the temp wiring! I was concerned the fire was too high in the firepot.. hoping if it ashed it would go down some, any input is appreciated. thanks!

This needs to ash only when the fan is running, and below the setpoint of the controller.

I believe the top number on your controller is just what the sensor is sensing.

If it's only been running for 5 hours it is not time for it to ash yet. You should probably go about a day before you let it ash. I would let it run, you have a whole day to figure out if the ashing is wired right.

just concerned about the super heated ash pan area,, and the height of fire,, does that all look ok to you don?

hotblast, its never ashed even once,, any idea of that top number and what it represents,,
?

I've seen 273 degrees and higher on mine, but it is rare. Did you start the fire with only coal in the pot, or did you add a couple gallons of ashes first and then add coal? I'm guessing the former, as you have may have fire clear to the bottom of the fire tube. That's OK, but adding a few pounds of ashes first gets things normalized faster. The high temperature is almost assuredly because you started with nothing but coal. You can turn the ash switch on now, since at 273 degrees in the ash grate area it will be a number of hours before it ever gets below 130 and starts ashing. I see nothing wrong here.

BTW: If it starts ashing at 120 degrees on the grate and stops at 130 degrees, then your hysteresis is set for 10 degrees.

You just fired it up so the fire is at it's most intense. There is no ash yet, it's all coal so, yeh, it's going to be hot. The main thing to keep an eye on is the water temperature. If that stays under 200, yer good.

Your ash pan area will cool down once you actually have ash rather than coal.

There is no top number, only the ashing setpoint which is a "makes contact on temperature drop" kind of thing.

You didn't do anything like, seal the ash doors, did you? The fire breaths the air that comes from under the 1/4" gap at the bottom of those doors.

The top number is 'effectively' the temperature of the ash grate at any given moment. 273 degrees is not all that high. I've seen 300's a few times as I recall. The bottom number combined with the hysteresis setting control the ashing.

The top number has absolutely nothing at all to do with water temperature. I'm willing to guess that hand fired stove grates routinely see appreciably more than 273 degree heat, and they are very weak components by comparison to the durable ash sled (grate) of the AA/AHS design.

yes, you are right, i had read about putting in ashes and i went by the book and did it with all coal, you are 100% correct,, i went thru the setup they sent me for the love conrols and have it set to 1 degree differential.

does the fire look ok to you as far as height wise in the pot? not too high?

Everything looks fine to me.

I have the water temp set at 150 and its kicking on and off about every 15 minutes,, I have all radiant on, both garage and house, and a water to air coil on, and a fan blowing ever so gently thru the dump zone Modine,, but the Modine is off ,,, also heating the 100 gallon reserve tank and an 80 gallon indirect water heater,, But I sure did have a heck of a time getting a fire started,,, but that's a whole different ball of wax,, but the floors are all about 50 in garage to start with and 70 in house, so its having to work pretty hard,, I am seeing 130 degree entering garage floor and 110 going into the house,, this is just about what I wanted. and this way it wont overheat my domestic, I don't have a temering valve in it .

260 coal gun up and running!!
