You're not following what the previous poster informed you to do. You need to measure the "low draft". To make it easier,
let the stove run in "test" mode for 2 minutes, and then when the stove starts blowing air into the room through the
air outlet, the stove will now be in "low draft" mode. It will stay this way for sixty seconds. It is in this sixty seconds
that the manometer should be read and potentiometer adjusted. After sixty seconds, the stove will return to "high draft"
mode for another sixty seconds. This "high draft"/"low draft" will now alternate.

Pellet brand/quality difference. Vent configuration. Do you have the distribution blower on high (or at least between low and high)? If you leave the dist. blow on low the stove may be reaching maximum exhaust temp on th ESP without a high flame. You may even have a defective ESP (can happen on brand new stoves)

Hi Cantman!
According to the book.. after 60 seconds in test mode, the combustion fan slows down and this is the
time to check/adjust. That is precisely what happens. The combustion blower does slow down. There
just isn't any adjustment via the potentiometer. I have a call into my dealer. I'll let you all know how
I make out. FYI, this is a boiler, there's no heat exchanger blower like a hot air furnace.
Thanks again.

Are you sure you're not confusing the combustion blower
with the room air blower? You will not be able to hear the
combustion blower when it increases or decreases. When the room
air blower is blowing hard through the front vent (where the "XXV"
symbol is), then the combustion blower will be at it's "low draft"
mode and ready for adjustment.

My XXV was taking 8 to 10 minutes to ignite. Also, I was getting way too many pellets in the burn pot. I thought it was the ignitor. After taking your advice on turning the draft back 45 degrees, it starts in 3.5 minutes. I didn't get any smoke at start up like I had previously. Problem solved. My dealer never adjusted the draft. When I asked about it, he replied that it wasn't necessary.
I am going to check and see how it runs at very low burn rates.
