Verify fi ring input range
Refer to appliance manufacturer’s instructions (if
available) for the fi ring input range. Otherwise the
maximum recommended fi ring range for the burner
depends on the length and width of the fi ring chamber
and the distance from the burner center to the chamber
fl oor. Verify that the chamber dimensions are at least as
large as the minimum values given in Figure 2. If the
appliance dimensions are smaller, reduce the fi ring rate
accordingly.

Test For Gas Pipe Leaks
Leaking gas could result in asphyxiation, explosion,
or fi re hazard.
The gas supply piping must be absolutely leak-free.
Pressure test the gas piping with air that is at least
three times greater than the gas pressure being
used.
Verify that there are no leaks before proceeding.
