Pilot Burners/Thermocouples
This document is intended to aid the appliance engineer or authorized
service contractor in making a standing pilot application. Pilot burners are
manufactured with a variety of tips and mounting configurations.
Representative types of mounting with standard pilots are illustrated in
Figure 1. Dimensions shown are approximate and may vary, provided the
requirements of good ignition are met. See Good Practice Rules.
The following are good practice rules for governing the location of the
pilot:
•
Locate the pilot so that it can be reached easily for lighting.
•
Locate the pilot in a position that has a fixed relation to the main
burner (see Figure 1).
Mounting Position Examples for Pilot Burners
Pilot Ignition Port 3/8" Above
and 1/4" Away (Or Closer)
from Center of Nearest Main
Burner Port
•
Locate the pilot burner in a position that will receive incoming air and
not products of combustion from the main burner. The pilot should
be located where it will not be affected by an excessive draft of
incoming air.
•
Locate the pilot burner in such a position that it does not receive the
full force of igniting or extinguishing puffs from the main burner.
•
Locate the pilot burner in a position that will allow ready removal for
cleaning.
