CHAPTER 5 Maintenance
5.1 — Overview
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 free him from certain repetitive chores, provid-
ing time for upkeep and maintenance.
Unusual noise, improper gauge reading, leak, sign of overheating, etc., can indicate a developing malfunction,
requiring corrective action.
5.2 — Control System
Most operating controls require very little maintenance beyond regular inspection. Examine electrical connec-
tions. Keep the controls clean. Remove any dust from the interior of the control. Covers should be left on controls
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
removed. They must be replaced, and securely anchored before testing, adjusting, or running the burner or burner
related equipment.
It is important that support is provided for the hosing when in the open position to prevent damage to the hinges and
subsequent components.
