Hello - I'm new to the forum and to pellet stove use. I was given a pellet stove that one of my older brothers, it came with the house that he purchased about a month ago. I know absolutely nothing about pellet stoves. I have an outdoor wood burning unit that I use when it's cold outside. My plan is to use the pellet stove during the spring and fall seasons when the outdoor unit is burning wood for reason other than keeping the water jacket hot. The pellet stove is a Whitfield WP2 Advantage manufactured in 1994. It operates pretty good until approximately a 1/2 hours time of use and then it shuts off. It has done this twice since firing her up. I purchased a few bags of "blend" pellets and a few bags of premium. Do you think I should change to the premium? Can you fine people offer me any advice as to what I can do to keep this thing running? Perhaps it's not cold enough outside for it to be used right now. Any and all suggestions are welcome. Roger
