If the system has been operated for a period of
time without the lamp(s) being illuminated (such as at
startup or with a failed lamp), an odor may occur when
lamps are (re)started. This symptom is considered to
be typical and should only be temporary. In the event
that an odor does occur, it should subside and dis-
sipate within 12 hours of full operation. If this odor per-
sists longer than 48 hours, immediately contact your
Lennox dealer.
Clean lamps prior to installation using a cotton
cloth to remove dirt and fingerprints.
Failure to clean lamps could reduce the system’s
efficiency.
