Been running 3 teeth on the feed, 2 wasn't keeping the boiler hot enough to produce enough hot water, but that was in the early spring, now the incoming water is not quite as cold. Low setting is 150 and the high is 200. Boiler temps have been staying around 170 to 180. Outfire timer was at 2 minutes every half hour for the warmer weather to keep the draft going (winter is 2 minutes per hour).
This morning the boiler was at an even 200 degrees. The obvious problem here is once the high limit is reached the timer won't fire the stoker, the fire could be lost. The other problem was the cellar was 90 degrees! I had 3/4 of the jacket on, no insulation except the front cover.
So I spent a good part of the day insulating the boiler, which is exactly the wrong thing to do for a boiler running near the high limit.
I also reduced the timer to 1 1/2 minutes every half hour.
I'll see what happens.
I have photos but I'm having problems posting, after I write a post and click "submit" I'm logged out and everything is gone, I'll post them after this problem is resolved.
