CLEANING THE EXHAUST PLENUM BOX
To ensure the continued safe and efficient operation of the oven, the
exhaust system should be cleaned regularly. Towards this end, the
oven monitors the total burn time that has elapsed since the last
cleaning and warns the operator when the elapsed time exceeds
1050 minutes. Upon completion of a burn cycle, if the total burn
time since the last cleaning is 1050 minutes or greater, the oven
displays:
WARNING! Clean NTO
Exhaust System. See
Operation Manual for
details. Press ENTER
When this warning is displayed, Troxler strongly recommends
cleaning the exhaust plenum box as described on the following
page.
To ensure that the exhaust system has been cleaned, when the
operator presses
〈
START
〉
to begin another burn cycle, the oven
displays the following reminder:
Have you cleaned the
NTO Exhaust System?
YES
NO, Remind me later.
f
If the exhaust plenum box has been cleaned, press
〈
YES
〉
. The
oven restarts the total burn time counter and proceeds with the
burn cycle.
f
If the exhaust plenum box has not been cleaned, press
〈
NO
〉
to
continue. The oven proceeds with the burn cycle, but does not
restart the total burn time counter. The oven repeats the warning
and reminder displays shown above until the exhaust system has
been cleaned and the operator has pressed
〈
YES
〉
in response to
the reminder.
