I just installed an Atrama 7 wood boiler in conjunction with my oil furnace. The instructions came in Lithuanian only, and I'm not sure how to set the vents/air controls to maintain a good fire. There is a side fresh air vent I'm guessing to assist cool air up the chimney for draft, there is the firebox draft door on the bottom and the top door for wood loading and the bottom door which also holds the draft door. I do not have an electronic draft blower. I can't get the temp of the water over 165. My oil furnace keeps trying to come on, even though I've set it at 160. Any ideas?

Have you got this corrected yet,if not maybe I can help.
What aquastat do you have on the oil boiler? I have the
same problem that the boiler wants to turn on if it gets
down to the low setting on the aquastat.I have to keep the
boiler heat up high to prevent this.This is the only way that my
oil boiler will kick on when the fire dies down in my coal
Next year I'm going to put an aquastat on the coal boiler to
have it control the circulator and let the oil just keep itself hot
to act as a backup if needed.All of my zone valves (4) will
be controled by the coal boiler aquastat.
Whats wrong with the Atrama 7?
European boilers are made to operate at 160 to 190 water
rather than the 190 to 200+ in the US.
With wood you use the side secondary air to get the gases
to burn before the heat exchanger and exrtract huge amount
of energy in the volitile gases the wood creates,when the fire is
going strong adjust the throttle to get a comlete burn indicated by
the white hot heat in the burn area.
I burn bituminous coal and I find that full open works good on
the volitiles and I get a torch like flame and high heat.
