Foreman Ductable Dual Fuel Indirect-Fired Heater

Duct Installation

This heater may be ducted using the approved
L.B. White distribution devices:
-- (2) 12 in./30.48 cm Dia. x 25 ft. / 7.62 m duct
kit, L.B. White Part # 30052, duct adapter not
required.
-- (1) 16 in. / 40.64cm Dia. x 25 ft. / 7.62 duct kit,
L.B. White Part #30076. Duct adapter part #30902
is required.
-- Substitute ductwork material is acceptable but
must conform to the following requirements:
Only the ducting and the air distribution acces-
sories as supplied and specifi ed by the heater's
manufacturer shall be used.
1. Duct must have a minimum material temperature
of 300°F/149°C
2. Ducting up to 100 ft./30.48 m can be connected to
the heater as long as the static pressure does not
exceed the dataplate limit. Increased static pres-
sure will reduce fl ow rate and can cause the high
temperature limits to shut the heater down. Bends
and kinks in the duct, or duct collapse are all likely
to increase static pressure.
-- Locate the duct under suitable wind barrier materi-
als for jobsite requirements.
3. Alternate 12" duct can be used from the following
manufacturer's:
- Artic Helix - Norseman
- Artic Econorush - Norseman
- Hitex Series - NTI Global
- Ventfl ex Series - NTI Global
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 fl ows freely, thereby
preventing overheating. If there are excessive
bends, the high limit switches may open.
OPTIONAL: Air Recirculating Duct Kit, 20 in. /
50.8 cm Dia. x 25 ft. / 7.62m, may be attached to
the heater supply air inlet.
