8.6 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.
See Section 5:
Safety Device Testing
in this guide for a description and instructions for
performing these tests.
8.7 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 of one or two burner gaskets
(depending on BMK model), and blower and gas train O-Rings, which are included in all 24
Month Maintenance Kits. 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 Kits. Instructions are in the
Technical Instruction Documents (TIDs) included with the kits:
