The P61A was installed before last season and replaced a St Croix. Nothing was up to code. The house is a 100yrs old and there is a damn window on every nook and cranny of every room. To be nearly legal where it was installed two of the 3 windows were caulked shut and non operating. You can see the size of these windows even with the old blue blanket covering them. All legal now just have to clean her and reinstall the oak.
