SPECIAL INSTALLATION REQUIREMENTS
This appliance is equipped with an automatic combustion characteristic adjustment system, provided the
installed elevation above sea level is entered into the operating control (FMT 914) when the height is greater
than 2,000 feet and less than or equal to 9,000 feet. To enter the operating elevation:
•
Press the
reset button
continuously for 3 seconds, the appliance shows the adjusted altitude
of the appliance (0 = sea level). Each time the
service button
is pressed, the value increases by
100 feet (20 through 90 = 2,000 through 9,000 feet). After reaching the maximum value, the
counter returns to the minimum value (example: when the value is 90 and the service button is
pressed, the new value will be 20). When the right altitude has been set (example: 53 = 5,300
feet of elevation above sea level), press the
reset button
for one second and the value will be
programmed. The factory default is 20 (which equals 2,000 feet), and there is no need to adjust
below
that.
See Figure 8-3 on page 56 for the button locations.
•
The adjusted altitude entered is internally converted to an offset on top of the maximum fan
speed.
•
By adjusting the combustion characteristics as described above, there is no de-rate
required at altitudes up to 9,000 feet. For elevations in excess of 9,000 feet or gas BTU
content levels below 950 BTU/cubic foot, consult the factory at 734.419.0200 or 800.968.5530
for adjustments and de-rating information.
