Thanks thats good to know, so the only time you need to adjust with a mag is if your changing to a different pellet than?, or once it is set you can adust with the trim for a different pellet ?
Depends on which model you get. If it has the trim adjustment I would use it. Lock the damper rod with provided collars. You can adjust the feed trim down(less fuel) for rich and up(more fuel) for lean. Combustion blower trim would be up(more air) for rich or down(less air) for lean. Both is trickier. Do one at a time and I usually start with the combustion blower trim.
My Omega only has feed trim. So I like using the damper. But I have used feed trim for final treaking.
You could adjust with the mag, Its more precise. But not really needed if cash is tight. Once its set its good to go all season. I got mine more to verify my vent is clean and I like to tinker! But I really don't absolutly have to have it. I did my own install, So it was cheaper to buy my mag than have it set by a tech(at $85/hr). I paid less than $40 total for mine on flea-bay
She chart below for mag settings.
Are you going to do you own install?
