We have a Lopi Northfield, recently installed, which renders our living room unusable because of intense odor. The installer put a new vent stack on saying “Let it run for 3 days.” Had to shut down the room due to intolerable odor. Turned the stove off, leaving pilot on. Opened windows even! This morning odor was less but still quite strong. Turned gas off to unit and called dealer. Told “We can have a tech to you by Friday, in a week”. Our stove has a “new metal” finish. Any experience with this stove, its’ finish, or this problem?
