A
CSA ratings for altitudes to 2000 ft.
B
Size shown is for gas connection to a single-stage gas valve, not supply line size.
C
Smaller and/or larger vent and combustion air pipe diameters may be permissible. For Separated Combustion models refer to the Venting
Installation Manual for Separated Combustion Units. For Standard Power Vent models refer to the Venting Installation Manual for Power Vented
units. For a Standard Power Vent model with Option AV6, refer to the Venting Installation Manual for Common Venting.
D
MOCP = 2.25 x (largest motor FLA) + smallest motor FLA. Answer is rounded to the next lower standard circuit breaker size.
E
Except where indicated, information in this table is based on a heater equipped with a standard 115 volt open fan motor.
