Procedure for Removing/Cleaning The Burner
Perform the following to remove/clean the burner:
1. Remove top and side panels from the boiler outer jacket.
2. Disconnect both wire plug connectors to the pre-mix blower.
3. Disconnect the UV scanner/fl ame rod, ignition wire and ground wire block.
4. Disconnect air sensing tubing from Venturi mixing unit, carefully swing the
tubing away.
5. Disconnect air switch sensing tubing between switch and Venturi mixing
unit inlet.
6. Disconnect high backpressure sensing tubing between switch and ignition
assembly connection point.
7. Disconnect the four bolts between the Venturi mixing unit fl ange and
the gas train fl ange. Verify the gas train is properly supported prior
to removing the above-mentioned four bolts, also verify supply gas is
isolated. Inspect gasket located between these two fl anges for signs of
deterioration.
8. Undo four nuts holding pre-mix blower to the burner/blower mounting
plate. Use care, the pre-mix blower/venturi-mixing unit is heavy. Inspect
gasket for signs of deterioration.
9. Undo four nuts holding burner/blower-mounting plate to the outlet water
header.
10. Remove burner, being careful not to scrape burner on heat exchanger or
outlet water header. Inspect gasket for signs of deterioration.
11. Inspect burner and wipe off (do not scrub or use wire brush) any soot or
foreign material that may have accumulated. If available, use compressed
air to clear the burner. Wipe out the inside of the burner with a clean cloth.
12. Check that the gap between the electrode and the ground rod. Gap
should be 1/8-inch (3mm) +/- 1/16,-0. For Liquid Propane, the gap should
be exactly 1/8-inch (3mm).
13. Check the horizontal gap between the point of ignition and the exterior of
the mesh burner. The required gap is 5/16-3/8-inch (8-10 mm).
