establish the gap opening.
3. Replace the old orifice with one for the new fuel. Pipe sealing compound is required to ensure a proper seal between the
orifice and the adapter fitting.
4. For information with regards to the size of the Primary Air Setting and orifice, please refer to page 32. To reinstall the
burner tube assembly please refer to page 24 & 24.
