This is being posted for a new VF3000 owner looking for inital settings at startup

I have my Vf3000 adjust pretty well now.

here are my inital settings for the VF3000

I have the A350 set to 170* and Diff set to 10
At this setting it will turn on stoker at 165 and turn off at 175 but then it might over shoot to 180* ( that is OK )

I have the s350 set to offset 15 and diff set to 10
At these settings it should start overtemp dumping at 205*
I haven't seen it do a overtemp dump since i got it properly adjusted.

setting your stoker rod:
loosen up the wing nut turn the arm_nut clockwise until it stops (this is max heat setting)
if yours is like mine it will stop in the 11 oclock position.
now turn the arm_nut counterclock wise 3.5 turns.
and lock the wing nut to the arm_nut so the arn_nut cannot move.
when you are done the arm should be in the 5 oclock position (if yours is like mine.)

This setting will give you 50% hot coals in the grate when it is making heat.

set the keep alive timer on to 2 and the off to 14


I live on long island so I have mild winters, right now it is 60* day and 40* nights so I don't need alot of heat. I just got my VF3000 adjusted right for about 2 weeks now.


The settings I gave you are a good starting point. If you need more heat turn the nut_arm clockwise a half turn at a time and watch it for 1 day before you adjust it again.
