Combustion efficiency

Well the good news is if I open the ash door some I am able to maintain a good flame/boil rate without using the AUF. I did remove the rain cap and pull the extra grating from the firebox so crisis maybe averted for now. I will take relocation the stack under advisement but it would be a summer retrofit.

I don't understand what's going on with the AUF. Are you trying not to use it for some reason? If it's properly sized, it should give you much more air to your fire than opening the ash door.

I have the same evaporator as you, and also have a long (around six feet) of vertical in my stovepipe. I have no trouble maintaining a good boil - I get between 11.5 - 12 GPH. I use a squirrel blower for AUF.

vertical? or horizontal?

I don't get the blower not functioning either but it seems to kill the burn when I turn it on.....regardless of volume of air I am pushing. I need to see if the fan is obstructed from the move north.

Oops, thanks for the correction. I meant horizontal. Is your blower AC or DC? If DC, could the wires be connected backwards? If so it might suck rather than blow!

Update: my last few boils have been fine with no issues at all anymore......I did remove that cap and the extra grates I had installed and the stove is firing normally now with the blower running. Thanks all for the advice. Tight lines, everyone.
