10.6 Checklist after installation

To verify the system was properly installed, perform the following checks:

– Be sure there are no leaks in the gas lines.

– Be sure all the components contained in the flame monitoring and control system,

pressure switch and wiring are properly installed.

– Be sure all components of the spark ignition system are installed and functioning

properly.

– Be sure the blower rotates in the proper direction. If the rotation is incorrect, have

a qualified electrician rewire the blower to rotate in the proper direction.

– Be sure all valves are installed in the proper location and correctly oriented relative

to the flow direction.

After installation of the burner system components is complete, the following steps

should be followed in order to prepare for adjustment:

– Set the air flow switch so that it drops out at 20% of the maximum pressure of the

combustion air blower.

– Set the low gas pressure switch at 50% below the gas pressure measured at the inlet

to the main gas valve train.

– Set the high gas pressure switch at 50% above the gas pressure measured at the

inlet to the main gas valve train.

– Try to ignite the burner before the purge and other timers have finished their cycles.

Make sure that the flame monitoring system indicates a flame failure.

– Trip out the pressure switches and other limit interlocks. Make sure that the main

gas valve train closes.

– If the simulated limit condition or the simulated flame fault cannot be responded at

the specified fault response time, the fuel system needs to be turned off to correct

the existing problems.

Special attention:

The SSA80 Series burners, described herein, are designed to mix fuel with air. All fuel

burning devices are capable of producing fires and explosions, if improperly applied,

installed, adjusted, controlled, or maintained. Do not bypass any safety feature; fire

or explosion could result. Never try to light a burner if it shows signs of damage or

malfunction.

If you are adjusting burner for the first time, you must follow these steps

Reset the system: Start circulating duct fan with valve fully open, close all the

automatic gas valves and manual gas cocks. Pay more attention to rotate direction

of blower.

Set the system to high fire, but DO NOT ignite the burner(s). Use the datasheet
