Maintenance
42 OAU-SVX005C-EN
1. Shut the system down totally, disconnecting or locking
out power supply.
2. Inspect the burner carefully, including upstream and
downstream sides of mixing plates as well as burner
body face.
Note: The complete burner assembly may have to be
removed for proper inspection and cleaning. Any
accumulation of scale or foreign material on either
side of the mixing plates should be removed with
a wire brush. Visually check that no holes in the
mixing plates are blocked. If burner ports are
plugged (even partially) clear with a piece of wire.
See maintenance of gas ports.
3. If any mixing plates are loose or missing fasteners,
tighten/replace as necessary. Always use zinc plated or
stainless fasteners
Note: The missing plates on the burner may display
hairline cracks. These cracks are normal and
caused by thermal stresses occurring during
combustion. The presence of these hairline cracks
in no significant way affects the combustion
efficiency or performance of the heater. Should a
large opening develop, the specific mixing plate or
plates must be replaced. Otherwise, it may cause
difficulties in cross ignition of flame across the face
of the burner.
4. Place the system back into operation and view burner
while cycling through full firing range. This will give a
visual check for blocked burner spots.
5. Inspect the flame rod and ignition electrode for dirt and
moisture. Wipe off if necessary. Examine for any
evidence of premature arcing. If in doubt, check
continuity of flame rod to be sure it is not grounding
out. Replace if required.
6. The porcelain on the ignition electrode must be intact
(not cracked). The spark gap should be 1/8 in.
7. Replace all access panels which have been removed
and operate the unit for a test period.
8. Check for normal response and function of all controls.
9. Check all gas piping for possible leaks using a soap
bubble solution.
10. Inspect the support means to be sure that everything is
firmly anchored in-place.
