CENTURION Installation, Operation & Maintenance Manual
SECTION 7: MAINTENANCE
7.5 Safety Device Testing
Systematic and thorough tests of the operating and safety devices should be performed to
ensure that they are operating as designed. Certain code requirements, such as ASME CSD-1,
require that these tests be performed on a scheduled basis. Test schedules must conform to
local jurisdictions. The results of the tests should be recorded in a log book.
7.6 Burner Inspection
The burner assembly should be
inspected
every 24 months to ensure that all components are
intact and functioning as designed. This requires the replacement the burner gasket and blower
and gas train O-Rings, which are included in the 24 Month Maintenance Kit. If the burner is not
fully intact, it must be
replaced
as soon as possible.
The burner assembly is located at the top of the unit's heat exchanger. The burner assembly
may be hot. Therefore, allow the unit to cool sufficiently before removing the burner assembly.
Burner inspection parts are included all 24 Month Maintenance Kit. Instructions are in the
Technical Instruction Documents (TID) included with the kit.

7.7 Condensate Drain Trap
All Centurion Water Heaters contain a condensate trap (P/N
24441C
), located external to the
unit, attached to the
exhaust manifold’s drain at the rear of the unit. This trap must be
inspected
for leaks and blockages,
cleaned
to ensure that the float is free to move, and
condensate flows normally, and the O-Ring (P/N
84017C
included in all 24 Month Maintenance
Kits) replaced if it is worn or damaged. In addition, you must ensure the vent (under the
removable cover) is free and clear of obstructions.
