Always follow the manufacturer’ s instructions when installing a new pilot burner. Read these instructions very carefully before beginning any work.
If no installation instructions are available, the following location and mounting requirements should be carefully observed:
1. Choose a location for the pilot burner that provides easy access, observation, and lighting.
2. Rigidly affix the pilot burner to the main burner. Other mounting surfaces should not be used (see Figure 5-60).
3. Mount the pilot burner so that the flame is properly positioned
with respect to the main burner flame (see Figure 5-61).
A pilot flame should never be exposed to falling scale, which could impair the ignition of the main burners. Furthermore, the flame should not be exposed to draft conditions or to sudden puffs of air sometimes caused by igniting or extinguishing the main burner. Always provide an ample air supply free of contaminating products of combustion.
