Red flag - he either doesn't understand how the unit works, or doesn't care.

Also, what feed rate for that 4.5 air?
You can check how many teeth it is, each time the pawl pushes forward on the gear.
Good questions. I would also check to see that the timer is wired properly and is actually functioning. The timer may have never been hooked up properly, might not be set correctly, etc. The default settings for this boiler are: 4 teeth of feed, 4 air, 160 low, 200 high, 10 differential, and 2 minutes every half hour on the timer. The draft needs to be checked, and the boiler/smoke pipe needs to be clean.
If you aren't sure how to check these things, I think it would be good to have someone more familiar with EFM's stop by to check it over. A good "coal guy" will check it out and show you the important things to look for. Matt Direnzo is one option. http://www.anthracitecoalstokers.com/
