must conform to the following requirements:
1. Duct must have a minimum material temperature
of 300°F/149°C
2. Duct length not to exceed 25 ft. /7.62 m per duct.
-- Locate the duct under suitable wind barrier materi-

NOTE:
■ When using the ducting, ensure that bends in
ducts are kept to a minimum. A maximum of two
90° bends is allowed.
■ Reducing the number of bends will ensure that the
warm air exiting the heater flows freely, thereby
preventing overheating. If there are excessive
bends, the high limit switches may open.
