Operational Test

When the installation and all burner adjustments are completed, the entire burner control system
should be tested in accordance with the burner manufacturer’s instructions. The procedure should
verify the correct operation of:

1.

Each operating control (temperature, pressure, etc.).

2.

Each limit switch (temperature, pressure, low water cutoff, etc.).

3.

Each interlock switch (air flow switch, high and low fuel pressure or temperature switches,   low
fire start switches, fuel valve proof of closure interlock, etc.).

4.

Pilot flame failure response and lockout.

5.

Main flame failure response and lockout.

6.

Tight shutoff of all fuel valves.

7.

Note: Before attempting to reset the lockout switch, wait approximately 2 minutes for the lockout
switch heater to cool.
