M. Maintenance
A maintenance program avoids unnecessary downtime, costly repairs, and promotes safety. It is
recommended that a record be maintained of daily, weekly, monthly, and yearly maintenance activities.
Electrical and mechanical devices require systematic and
periodic inspection and maintenance. Any
“automatic” features do not relieve the operator from responsibility, but rather frees him from certain repetitive
chores, providing time for upkeep and maintenance.
Unusual noise, improper gauge reading, leak, sign of overheating, etc. can indicate a developing malfunction
re
quiring corrective action.
ONLY FACTORY AUTHORIZED BURNER SERVICE PERSONNEL SHOULD START UP, ADJUST, OR
SERVICE THE EQUIPMENT.
ANY COVER PLATES, ENCLOSURES, OR GUARDS ANCHORED TO THE BURNER, OR ANY BURNER
RELATED EQUIPMENT, MUST REMAIN IN POSITION AT ALL TIMES. ONLY DURING MAINTENANCE
AND SERVICE SHUTDOWN CAN THESE COVER PLATES, ENCLOSURES, OR GUARDS BE ALLOWED
TO BE REMOVED. THEY MUST BE REPLACED, AND SECURELY ANCHORED BEFORE TESTING,
ADJUSTING, OR RUNNING THE BURNER OR BURNER RELATED EQUIPMENT.
CONTROL SYSTEM
Most operating controls require ver
y little maintenance beyond regular inspection. Examine electrical
connections. Keep the controls clean. Remove any dust from the interior of the control. Covers should be left
on controls at all times. Keep the control cabinet doors closed. Dust and dirt can damage motor starters and
relay contacts. Starter contacts are plated with silver and are not harmed by discoloration. Never use files or
abrasive materials such as sandpaper on contact points.
PROGRAMMING CONTROL
This control requires no adjustment, nor should any attempt be made
to alter contact settings or timing logic.
Those programmers with contacts may require occasional cleaning. If so, follow instructions given in the
manufacturer’s bulletin. Never use abrasive materials. The manufacturer’s bulletin also contains
troubleshooting information. The flame detector lens should be cleaned as often as conditions demand.
A periodic safety check procedure should be established to test
the complete safeguard system. Tests should
verify safety shutdown with a safety lockout upon failure to ignite the pilot or the main flame, and upon loss
of flame. Each of these conditions should be checked on a scheduled basis. The safety check procedures are
contained in the manufacturer’s bulletin.
