and mounted.
The oil burner is mounted on three stud mounting bolts on the mounting plate covering the opening in the
front of the heat exchanger. This unit is designed with a pre-positioned chamber. There is no insertion
adjustment necessary. The unit requires only the mounting of the burner. Insertion is pre-determined.
The top panel is removable by taking out the four screws for easy access to the burner and the piping.
