THE UNIT, AS SHIPPED, IS FACTORY SET AT SETTING "A" TO RUN AT THE MIDDLE OF THE HEATING RISE RANGE SHOWN ON THE UNIT RATING LABEL.
When operating the furnace in the heating mode, the static pressure and the temperature rise (supply air temperature minus return air temperature) must be within those limits specified on the rating label. Failure to follow this warning could lead to severe furnace damage.
Turn OFF all gas and electrical power to furnace before performing any maintenance or service on unit. (Unless specific test requires gas and electrical supplies.) Failure to take this precaution may result in personal injury due to electrical shock or uncontrolled gas leakage.
