Ash Post-Mortem

PostBy: Chief20 On: Sat Jan 17, 2009 10:27 am

I am new to coal burning. Just bought a 2300 square foot Gambrel in central MA. Previous owners had a Russo #1 coal wood stove installed in 1983. They burned some wood over the years but never coal. All inspections of the stove and fireplace were performed prior to the closing and the stove was given a clean bill of health. I added a baro will help form this forum set for .05" per the manual. I am burning Blaschak nut. No problems lighting or loading. I find that I have to poke up from the ash pan to clear the corners after shaking. Its throwing plenty of heat. It will bring my 2300 sq ft from 68 to 72 with -6 outside in 3 hours. I am very please with its performance. However, I have been only able to keep it going through to morning twice and both times were barely recoverable. Last night we turned in at 11:00 and by 2:30 the there was nothing left of the fire. I happened to wake and wanted to check on it. This is a photo of what I dug out of it this morning. I'm up again on wood and slowly adding coal and will try again. I had the ash door air slide set on 2 and the fire looked strong when I last saw it. Any advice?

Are you filling it to the top of the firebrick when loading it for the night? what temp are you running the stove at? Is the coal mostly burned up upon waking or just extinguished?

Looks like the coal is mostly consumed, indicating the stove needed more new coal to continue burning.
How much coal, by weight or gallons, does the stove hold when you fill it from empty?

I have a Rutland and Minuteman thermometer side by side. The Minuteman is as old as the stove. The Rutland I purchased this week. The Rutland indicates 450 and the Minuteman 550. Russo's manual states that a coal load is 30-35 pounds. I managed to get 30 pounds or 3/4's of a 40 pound bag in it last night. 1/3 of the ash bucket is black, 1/3 is white and 1/3 is gray. I intend to borrow a digital contact thermometer this week to determine which is more accurate. Thanks for the help.

Back up on coal. Stove temp is 300 and nicely rising. Blower kicked in about 10 minutes ago. Stove room is 72 and comfortable up from 66 when I started 2 hours ago. Ash door is closed and I've set the air control back to were it was last night. Will watch wait and see. Can the stuff I dug out this morning be fed back in?

The black colored pieces at 10% of the load to be safe.
How far open were the air vents open?
At 35 lbs it is a small stove heating a large space, you need to either feed often when cold outside or cut back the heat output to get a longer burn.
The Russo is a great stove, but you will need a bigger stove to heat the house with low outside temps and a desire for 8-12 hour burn times.
My MarkII holds 90lbs when I stuff it full and would not go 12 hours at 500* body temp.
The 'rents Hitzer 503 insert will take 120 lbs when stuffed!

Fill it up! Coal likes it deep.

I just looked up the heating capacity in Russo's manual. Its rated for 11,000 cubic feet (Max) thats about 2/3's of the space that it is currently heating. If you can actually get that kind of performance out of the stove. Currently the stove room is a comfortable 72 with the coldest room at 68. Outside temp is 13 and its a sunny day. Any thoughts on running this stove at a lower surface temp in an effort to try to prolong the burn. I am more concerned now with keeping the burn going than the amount of heat it throws. This heating season is going to be a learning experience. This house also has provisions for a second stove in the finished basement. The previous owners finished the room with the future expectations of adding a second stove. I had pondered the idea of moving the Russo into the basement and replacing it with an insert. The dog agrees we can't give up on this project. Thanks for the help.

Chief,

Nice Russo....

And is that dog a Pug?

A friend of mine bought one, I told him he was the only person in the world that would pay $400.00 for a dog that looked the same on both ends! :lol:

It's hard to tell in the photo, but a friend of mine has a vigilant that looks about the same size. His is a whole new stove since I went over and encouraged him to fill 'er up. It doesn't make it hotter, that's controlled by air inlet, but it gives it the fuel it needs for a longer burn. But, now that he's learned to fill it up, he does run it hotter also.

It looks like you might not have a barometric damper. It's possible you are losing a fair amount of heat up the chimney.

Sure is. Best dog I've ever owned and your friend got a bargain. I've been stepping over her all morning, but she sure loves the fire.

There is a baro hidden behind. Not much stove pipe before it disappears into the fireplace damper. Here are some pictures I used on this forum when I added the baro and manometer to adjust it. Baro was set at .05 per Russo's recommendation. Its actually open about 1/2" currently with the stove temp at 450. This typically is where I like to keep it. I just may be burning out overnight at this rate.

11,000 cu ft with 7'6'' ceiling yields 1467 sq ft heated.
Stoves are usually rated under ideal conditions not real world.
Most medium sized stoves hold 50-80 lbs coal, heat 1200-1800 sq feet and will hold a fire for 8-14 hours before needing coal.
Your run time seems 'normal' given your 'conditions'.
An insert would work out well with the smaller stove relocated down stairs.
Long thread on the Hitzer 503 insert, but I am biased, 'rents love the Hitzer heats 2000 sq ft gambrell to 75* on a medium setting 350* when it was 10* outside.
Bottom line is 'stove is not big enough to heat the given space and burns up the limited amount of coal attempting to do so'
You need to upsize that stove!
Some pics or descriptions of the other flue will help!
Is the basement finished?

That baro looks to be upsidedown, is the weight on top or bottom?

Basement is finished. Ceiling was modified with fire rated drywall. Flue access was left accessible with simple trim cover located approximately 50" off the floor. Floor is ceramic tile over concrete slab. Don't know flue dimensions, have only been in the house for 2 months.

The baro is a Field Controls Company Draft Regulator 6" Style B34. The counterweight is on top at 12:00 position the weight is actually on the flue side of the damper. What is seen is the knurled knob and hex nut that is used to position the counterweight and lock it down when adjustment is complete.

Currently the stove has settled in at 400F with the ash door air adjuster set at "2" which is the mid position and the baro is open about 3/8" measured at the 6:00 position. Stove room temp is 75F and outside temp is 24F.
