servicing.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in unit damage or improper
operation.
Do NOT use this kit with furnaces with an input of 26,000 BTUH; the
unit will be severely over-fired. This could result in delayed ignition,
sooting or premature heat exchanger failure.
