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.

CSmaller and/or larger vent and combustion air pipe diameters may be permissible. For Model UDAS refer to the Venting Installation Manual for Separated Combustion Units. For Model UDAP refer to the Venting Installation Manual for Power Vented units. For a Model UDAP with Option AV6, refer to the Venting Installation Manual for Common Venting.

DMOCP = 2.25 x (largest motor FLA) + smallest motor FLA. Answer is rounded to the next lower standard circuit breaker size.

EAll other information is this table is based on a heater equipped with a standard 115 volt open fan motor.
