The Harman VF3000 Coal boiler is not supported factory direct and most dealers have little if any knowledge of them. Please copy and paste links from the past and post here in the future any info that would be helpful to VF3000 owners.

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.
