When an appliance is converted from a liquid or gaseous fuel
to a solid fuel, the conversion burner must be listed by Underwriters'
Laboratory or by an independent nationally recognized testing laboratory and
must comply with all Sections of this Chapter.
9.14.1
Testing in Individual
Appliance Required
A conversion burner must be tested for use in the individual

2. The conversion
burner has been tested by an independent testing laboratory in the individual
appliance in which it is intended to be installed and has been certified for
use in such appliance by the independent testing laboratory; or
3. The conversion burner has been tested by
the appliance manufacturer in the individual appliance in which it is intended
to be installed and has been approved for use in such appliance by the
appliance manufacturer.
Such appliance manufacturer or licensed professional engineer
must provide installation and combustion set-up instructions for the
appliance.
9.14.2

be returned to service at some future date, all of the following requirements
must be met before the alternative fuel is used:
9.14.6.1.1 The vent piping must remain intact

9.14.8
Limited Control
Required
Furnaces must have a 250 degree Fahrenheit limit control
installed in the supply plenum not more than 10" above the top surface of the
heat exchanger. The limit control shall extend at least 12" into the supply
plenum.
