compressed air through it. NOTE: Care must be taken not to ream the orifice hole to a larger diameter
as this will result in over firing the burner and potentially causing damage to the emitter.
4. Apply pipe thread sealant Part No. 05001010 PIPETITE-STIK #11175 (resistant to LP Gas) to the threads
of the orifice and replace it into the orifice fitting. Avoid over tightening the orifice as this will make
future removal very difficult.
5. Before removing the burner base it is advisable to make sure you have spare spacer screws and nuts
available Part No. 40219520 (#10-24 MALE x MALE THREADED HEX – SS) and Part No. 02127250
(#10-24 HEX NUT – SS). The spacer screws and nuts used to secure the burner are stainless steel and
may gall and therefore shear off during disassembly. See figures below for spacer screw replacement.
6. Remove the main burner. Clean around the burner cap ports and upper burner surfaces with a small
bristle brush (available as an accessory, Part No. 43295010) or other small wire brush. After cleaning the
burner ports, use the same brush to clean inside the burner base and venturi. Compressed air can be
blown onto the burner ports and through the burner venturi to remove any remaining dust.
7. Clean both the inside and outside surfaces of the perforated emitter assembly with a large bristle brush
(available as an accessory, Part No. 43295020) or other large bristle type brush; then use compressed
air to remove any burnt dust or dirt particles from the emitter.
8. Blow all dirt and dust off the canopy with compressed air.
9. Care should be taken when reassembling the burner base to avoid distorting the burner by over
tightening the securing nuts. See figure below. If any spacer screws sheared during the removal process
they must be replaced. The hex locknuts holding the spacer screws are accessible from inside the
emitter assembly, see the figure below.
10. Review the hex nuts to ensure that they are tight.
