IMPORTANT: On all installations without a coil, a removable
access panel is recommended in the outlet duct such that smoke or
reflected light would be observable inside the casing to indicate the
presence of leaks in the heat exchanger. This access cover shall be
attached in such a manner as to prevent leaks.
