The most I can recall seeing was 0.22" of water column.

Was that with properly functioning baro?

If I pin mine shut the highest I've seen here is -.1

About a week and and half ago I went to a coworkers house to help him with burning coal in his Clayton 1602. I took my mano with me to test his draft. Low draft certainly was not his problem. After getting some kindling burning we saw -.25 No baro.

IIRC KY Speedracer sees even higher than that on his.

When I set my Axeman 260 up I was worried about draft, not having enough. It was all piped up with a baro but nothing in the firetube, it was completely empty, devoid of ash and coal as it would have if operational. When I turned it on and the blower started, the manometer banged 9.0 and settled down to around 8.5. Needless to say, I had more than enough draft. It literally vaccuumed the floor around the boiler! At first I had no idea why it could be so high. Come to find out, it needs about 8" of ash and about the same of coal on top to tone down the suck that monster blower puts out.

Not sure. First big windstorm sucked all the fluid out and I haven't bothered monitoring the draft since. ;)

That's freakin hilarious!

Rob, so you mean to tell me that the draft was strong enough to lift a column of water 3 inches?

Rob, you wouldn't happen to have a dog named Toto, would you?

I actually used a mechanical draft meter rather than the fluid type, and yes I have seen it at or slightly above 0.3" WC. When it is really windy I can hear the cast iron chimney clean-out door rattle.

At one time I had a draft meter, stack temp. thermometer, and an hour meter that recorded the stoker run time. After removing the stove pipe for the 2nd or 3rd time to clean it at the end of the season, I decided not to reinstall the draft meter and thermometer. I really was not doing anything with the information, so why bother? I did use the hour meter up until this fall, which was kind of neat because you could compare coal consumption to previous years...but I ended up removing it when I rewired the controls a month ago.

Oh okay, I just assumed it was one of the Dwyer Mark II model 25 manos that measure up to 3 inches wc. That's a hell of a draft, don't let the cat near the baro lol or he WILL be last seen at 10,000 feet sailing over Burlington hahaha.

(thoop,.... REOW!)
