9. The hose assembly shall be visually inspected on
an annual basis. If it is evident there is excessive
abrasion or wear, or if the hose is cut, it must be
replaced prior to the heater being put into opera-
tion. The hose assembly shall be protected from
animals, and contact with hot surfaces during use.
The replacement hose assembly shall be that
specified by the manufacturer. See parts list.
10. Check for gas leaks and proper function upon
heater installation and before building repopula-
tion.
11. This heater should be inspected for proper
operation by a qualified service person at least
annually.
12. Always turn off the gas supply to the heater
when not in use.
13. This heater is equipped with a three-prong
(grounding) plug for your protection against
shock hazard and must be plugged directly into
a properly grounded three-prong receptacle.
Failure to use a properly grounded receptacle
can result in electrical shock, personal injury, or
death.
14. Direct ignition heaters will make up to three trials
for ignition. If ignition is not achieved, the control
system will lock out the gas control valve. If gas
is smelled after system lock out has occurred,
immediately close all fuel supply valves. Do not
relight until you are sure that all gas that may
have accumulated has cleared away. In any
event, do not relight for at least 5 minutes.
15. Use only approved gas hose or approved flexible
connectors which are rated for use with propane
or natural gas.

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 tube, causing fires leading
to building damage and injury to livestock and
humans.
-- Higher temperature differences over the length
of the tube, causing problems in temperature
control and bird performance
This heater requires clean, fresh air from a normal, atmo-
spheric 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. 2 and 3.
-- 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 cre-
ate a negative pressure.
