SCHEDULED MAINTENANCE

Helps prevents downtime and inefficient performance,

and keeps your Boiler System in peak operating condition.

Once yearly we will:

• Open boiler doors.
• Visually inspect door seals and gaskets; repair and/or replace if so required.
• Visually inspect tubesheets for heat distortion or cracks and report.
• Visually inspect boiler fire tubes for signs of cracks, leaks, or heat distortion and report.
• Visually inspect main fire tube or Morrison tube for damage and report.
• Visually inspect refractory on doors, burner throat and liner tiles, repair cracks, wash coat and report.
• Inspect all linkages, cams, shafts, adjust and lubricate and report.
• Remove all handhole and manhole covers, drain and flush boiler, replace all gaskets, refill and hydrostatically test vessel at operating pressure.
• Arrange for inspection by the boiler inspector at this interval if so required.
• Remove head of float type low water cut off, inspect bulb for signs of leak, inspect linkage for freedom of movement replace gaskets and assure operation of control.
• Inspect relief valves for proper rating, both for pressure and input of boiler
• Check all safety components for proper operation, which includes:
• Flame safeguard relay - 4 sec. Flame response max
• Combustion air proving switch
• Low and Hi Gas Pressure Switches
• Operating Controls:
• Manual reset Hi-Pressure/Temperature Control
• Operating control pressure/temperature
• Rate of fire control
• Manual rate of fire control
• Inspect operation of blower motor and pump motors, check for noise in bearings, amperage draw, and report
• Check and inspect solenoid and motorized gas valves for leakage, perform lock up test and report.
• Set combustion for optimum fuel utilisation and minimum stack emission using flue gas analyser and report.

Semi-annual Preventative Maintenance Program

Every six months we will::

• Check the boiler for safe and efficient operation.
• Combustion Analysis and adjustments to fire with both gases.
