Works great. I make a small camp type fire at one side of the burn pile, theat I know will start up. Once it starts, I use the blower over that small area. Much like a blacksmiths fire pit, the blower will get a very hot fire going. The speed of the bolwer varies as necessary to tend the fire. Usually it is only needed to get things started, especially if the pile is damp at all.
Are you allowed to burn now? Out here, even a charcoal grill is kinda scary now. We've had 40-50,000 acres burn over the last few weeks, and we are not even at the peak of fire season yet. One of my Fire Fighter buddies from the station I used to work out of just got back from a strike team on a fire about an hour from here. Tinder dry conditions, crowning in the trees and brush....
Seems a lot of insurance companies are not taking on new policies in urban interface zones now, and are also starting to not renew policies. The San Diego fires really had an impoact on them. Calif Dept of Forestry recomends 60' of fire safe clearance, but now the insurance companies are asking for a LOT more, even if the brush is at the neighbors.
Whatever you do, be safe about it, get the right permits, confirm with your local FD it is a permissive burn day, and your pile is proper size.
