A contractor installed an Astria Compass DLX 55 inch linear fireplace in place of an older gas log set in October. The flame is uneven ...right side flame different than left side. Also have problems with sooting. Not terrible but more than the "once a year" cleaning suggested in the manual. Contractor seems frustrated. I'm frustrated. Seems there is no one to call at IHP, the manufacturer. I've searched the websites and made calls with no results. Anyone know where to go to get some answers? Help!
