3. Install the orifices in their correct location according to
the tables above.
• All of the replacement orifices in the conversion kit
have straight threads (not pipe threads) and do not
require thread sealing compound.
4. Perform a gas leakage test of each orifice and
associated supply tube fittings. See "Check for Gas
Leaks" on page 8.
• Leak-checking should occur after the orifice
conversion is complete, and before the burner is
reassembled and tested.
