High altitude installations

For altitudes above 5,500 feet,
must be set to the proper Lightoff rate
addition, the minimum and maximum firing rates
must be set as specified for high altitude. Follow
the procedures given in "Set/verify blower speed
settings" on page 90. Failure to properly set the
firing rates could result in unreliable operation
and loss of heating.
