Just had a new M55 insert installed by the dealer and have turned it on three times. Twice the pellets funnel in the center and do not drop from the sides causing the fire to go out. Third time the fire went out right after I put in a bag of pellets. I've turned the stove ft each time and it restarts fine. I'm using Golden Fire pellets and the dealer and I are trying to figure this out. Help would be much appreciated.
