The standard door option requires that the rectangular

from the wall.
• Apply RTV sealant or butyl tape to the entire back flange of
the bezel.

Bezel
• Place the bezel over the tabs and flush with the front edge
of the casing. Be sure the edge of the bezel marked "TOP"
faces the top of the casing. Bend the casing tabs over the
bezel.
• Push the Furnace and bezel against the side wall. Secure
using six #6 or #8-18 Pan Head Type A screws (not
provided) placed through the bent tabs, bezel, and into
the RV wall.
• Place six more screws (three per side) to the le and right
side of the bezel. The bezel MUST fit tightly against the
