Windows
If a window is punctured, signifi cantly
scratched or removed from the throttle cup,
the burner performance could be impaired,
resulting in safety lockout, appliance soot-
up, equipment damage, hot gas puff-back
and asphyxiation hazard.
Use a clean soft cloth and degreaser, on an annual
basis, to remove any build-up or dark stains from the
windows.
If damaged, replace the nozzle line assembly with
an assembly that has a windowed throttle cup.
