I am curious if other VC Montpelier insert owners find that the air handle does not seem to slide fully to the left. There is a detent that seems like it is there to lock the flue full open. When I slide my handle to the left it stops before I can lock into the detent. The insert seems to be doing just fine but a little more air at startup would keep me from opening the door to get s solid draft started. Anyone able to move their lever fully to the left?
