Inlet Air Requirements
WARNING
Combustion Hazard
■ Provide a properly located and sized fresh air
inlet for the heater.
-- Refer to Inlet Air Requirements instructions.
■ Failure to provide a fresh air inlet can lead to:
-- Sooting causing building damage
-- High carbon monoxide levels, causing serious
injury or death to livestock and humans.
-- Overheating of the first 10 ft. tube, causing
fires leading to building damage and injury to
livestock and humans.
-- Higher temperature differences over the length
of the tubes, causing problems in temperature
control and bird performance
This heater requires clean, fresh air from a normal,
atmospheric pressure environment for proper
operation and combustion. Contact L.B.White
Company if you have any questions regarding the
installation of this heater.
Inlet air may be drawn from the attic or through side
walls under a protective eve. See Figs. 3 and 4.

Owner's Manual • Oval Radiant Tube Heaters
-- All inlet air seams and joints must be sealed
-- Do not use any filters on the air inlet system
-- The air inlet system must be kept as
straight as possible. No more than 1 -
90º bend is allowed.
-- Contact L.B.White Co. if you have any questions
regarding the installation of the heater.
Inlet air for combustion MUST NOT be drawn
from:
■ Inside the confinement room.
■ An attic or location where negative pressure
(vacuum) affects the air draw of the heater's fan.
Examples include, but are not limited to:
a. Houses with attic soffit vent area smaller than
ridge cap vent area
b. Heater air inlet located within 20 ft. of building
ventilation fans
c. Locations where wind and/or the elements can
create a negative pressure.
Ensure inlet cap is
unblocked by insulation.
Inlet tube must be
12 in. min.
above insulation
Cut 4-1/4 in. hole in ceiling adjacent to
joist. Spread insulation away and fasten
ceiling flange to joist.
Flex tube: Cut to length
-- Do not exceed 4 ft. max. length
-- Do not kink (part #573382)
