These units go into high fire after 10 minures of low fire there is a dip on the board that we have been using to eliminate low fire. Or there is the option of jumping out W1` and w2 to get high fire right away. Are you running a 2 stage t-stat?If not F low fire and jump w-1 and w-2. 2 stage to me is stupid.
