NOTES: 1. Airflow values in cubic feet per minute (CFM) rounded to nearest five (5) CFM.
2. Data taken without filters in place.
WARNING
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.
WARNING
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.
