-- With the main burner in operation, check all
connections, hose connections, fittings and joints
as well as the gas control valve inlet and outlet
connections with approved gas leak detectors.
-- If a leak is detected, check the components
involved for cleanliness in the thread areas and
proper application of pipe compound before
further tightening.
-- Tighten the gas connection as necessary to stop
the leak.
-- If necessary, replace the parts or components
involved if the leak cannot be stopped.
-- Ensure all gas leaks have been identified and
repaired before proceeding.
11. A qualified service agency must check for proper
operating gas pressure upon installation of the
heater.

13. It is extremely important to use the proper size
and type of gas supply line to assure proper
functioning of the heater. Contact your fuel gas
supplier for proper line sizing and installation.
14. This heater can be configured for use with either
L.P. gas vapor withdrawal or natural gas.
Consult the dataplate, located on interior of the

figuration of the specific heater. Do not use the
heater in an L.P. gas liquid withdrawal system or
application. If you are in doubt, contact the L.B.

15. Eventually, like all electrical/mechanical devices,
the thermostat can fail. Thermostat failure may
result in either an underheating or overheating
condition which may damage critical products
and/or cause animal injury or death.
Critical products and/or animals should be
protected by a separate back-up control system
that limits high and low temperatures and also
activates appropriate alarms.
