Instructions for installing the spark electrode and sensor assembly are
typically provided by the appliance manufacturer. It is important to follow
those instructions. If such information is not included, use the following
basic instructions.
Location/Mounting
The pilot burner/igniter-sensor must be positioned for easy access and
securely mounted to the main burner to ensure that the pilot burner flame
remains properly positioned with respect to the main burner flame. The
pilot burner must be located such that the flame receives an ample supply
of air free from the products of combustion. The flame must not be
exposed to draft conditions, the full force of main burner ignition, or
falling scale, which could otherwise impede ignition of main burner flame.
The pilot burner/igniter-sensor should be securely mounted to the main
burner with metal screws at a distance approximately 9.52 mm (3/8 in.)
above and 6.35 mm (1/4 in.) away from center of the nearest main burner
port. Ensure that the main burner flames do not impinge on any part of the
pilot burner.
Make sure that the flame sensor wire and the high voltage spark
transformer cable are separated from one another by a minimum distance
of 6.35 mm (1/4 in.) and not wrapped around any pipe, other wiring, or
devices.
