10.9 Stop Procedure

Do not turn the combustion air blower off until the chamber temperature is below

120°C. This will prevent hot gases from back flowing into the burner and blower

causing damage to the burner.

1. Stop the burner through the burner control system.

2. Run the combustion air blower until the chamber temperature drops below 80°C.

3. Shut off the combustion air blower.

4. Close all manual gas valves to the burner

Preventive maintenance is the key to a reliable, safe and efficient combustion system. The

core of any preventive maintenance system is a list of periodic tasks. These are guidelines

only. The customer should make the final determination on maintenance intervals and

tasks to be performed while considering the working environment.

System regular safety audit must be taken out, including gas leakage check no longer than

every half a year. If necessary, the frequency of audit should be increased. Leak detection,

control functions of the equipment must be included in the scope of audit. Only Anderson

technicians or those who are been trained and qualified by Anderson, as well as other

relevant professionals, can maintain the burners. All valves, especially ball valves, must be

slowly open or close when switching in order to prevent pressure shock in pipe.

– Inspect the flame sensing devices for good condition and cleanliness.

– Check for proper air and gas pressures.

– Test all the system alarms for proper response signals.

– Check and clean igniter electrodes.

– Check valve motors and control valves for free, smooth action and adjustment.

– Check for the proper operation of ventilating equipment.

– Test the interlock sequence on all safety equipment. Manually force each interlock to

intentionally fail while at the same time noting if related equipment closes or stops as

specified by the manufacturer. Test the flame safeguard by manually shutting off the

gas to the burner.

– Test the manual gas shut off cocks for proper operation.

– Inspect and clean the combustion air blower rotor. Clean and/or replace the

combustion air blower filter if applicable.

– Leak test the safety shut–off valves and pipe for tightness of closure to make sure no

leakage.

– Test the pressure switch settings by checking the switch movements against pressure

settings and comparing these with the actual impulse pressure.
