ETL rating for altitudes to 2000 ft.
D
Size shown is for gas connection to a single stage gas valve, not supply line size.
E
Smaller or larger vent pipe diameters may be allowed; refer to the Venting Installation Manual, Form I-V-PV. If vent diameter is different from vent connection, reducer/
enlargers will be field-required.
F
MOP = 2.25 x largest motor FLA + remaining load. Answer is rounded down to the next size of commercially available circuit breaker or fuse.
G
All other information in this table is based on a heater equipped with a standard 115 volt open fan motor."
