Hotblast 1357 Mods

Here are the mods that I have done to my hotblast 1357 with the help of this great forum and the people on it. I am heating a 2000 Sq. Ft. ranch style with basement. I am running this furnace right now at 19.3 lbs per day at 24 tend times, 130-180 over the load door temps, I have been lit since 10/4/14 I went and bought 3/4 inch black steel pipe the length of my stove, installed a 90 and cut 1" off from my front fire bricks so that I could run the black pipes down into the ash pan area, I got the formula from lightning that told me how many holes to drill for equal air flow. it works great so far, and this way I did not have to drill big holes the front of my stove. I came across some mica from the father-in-law that I used for the glass door, I only wanted to view the fire to see what it was doing without disturbing it with the load door open, so I did not see the need to cut a big hole and get a piece of glass, this works great and I did it with pieces lieing around the house. I moved my snap disc that controls my plenum fan to in between the two 8" warm air ducts and installed two quarters under neath it so that it would stop short cycling so much when running at low temps, this works great also. I also installed the over fire safety snap disc in the same spot, set to 175 degrees, I bought this snap disc from grainger for around $20. next I wanted to have some thermostat control of my furnace, so I got a used zone valve from a friend and made a bracket to the back of the furnace jacket, the 1/1/2" pipe coming out the back of mine feeds under grate air, and is the factory spot that the forced combustion fan goes on that you can purchase from U.S. Stove. So I bought a rain cap for a exhaust from tractor supply as a flap, and hooked a chain up to the zone valve with a arm that I bent that fits into the zone valve. I know that if I leave my manual spin draft control at a turn and a half during the day my furnace will keep a temp above 130 and will not go out seeings I do not need much heat during the day due to the sun heating the house, and I simply open it too 2 turns during the night, so I set my thermostat to say 72 degrees, and if my furnace cannot keep the house at 72 or higher with the manual settings, the thermostat opens the actuator and that lets in a small amount of extra air which ramps my stove up enough to satisfy the thermostat, since 10/4/14 my house has not dropped below 72 unless I turn it down, it is working great, now when it gets colder I will simply run my manual control at say 2 turns during the day and 2/1/2 at night, or whichever it needs, this is not a complete thermostat control of my furnace, this is to simply help when there is sudden temp drops outside or cold winds which happen often, so far the only problem ive had is the zone valve, it is old and the plastic gear is stripping, but I already have a actuator from McGiever that I am currently setting up and this one will not fail and will work great, I will keep everyone up to date on here. I hope this helps a lot of people that have these and anyone else, these furnaces are on the cheap side but can burn anthracite great! I would like to thank lightning (Lee) for the inspiration on all of these mods and the tips and tricks to make all of this happen and a thanks goes out to everyone else on here, a lot of great knowledge on here!

Absolutely, I love the exhaust rain cap idea with the zone valve as well as the snap switches for the plenum fans...clever yes and then some!

Here's what I did with some mica.

That would be nice but I would need to figure out another way to get control of my over the fire air.
My bit is really sensitive to that.

I forgot your burning bit, oh could put another spin on the load door

Just a lil update, I will try to clean the mica tonight to get a better pic of the pipes in action.

I re orientated them.. Very nice!
By the looks of the flames, I'd say that is just the right amount of secondary air

I think so too! Hopefully tonight after I get done snow blowing I can clean the mica and get a real good pic

Nice looking fire. How old is that burning coal bed? 12 hrs? 20 hrs?
