Checklist After Installation
To verify proper system installation, do the following:
Verify that there are no leaks in the gas and air lines.
Verify all components of the flame monitoring control system
are properly installed. This includes verifying that all
switches are installed in correct locations and all wiring,
pressure and impulse lines are properly connected.
Verify components of spark ignition system are installed and
functioning properly.
Verify that the blower rotates in the correct direction. If
incorrect, have a qualified electrician rewire the blower to
reverse its rotation.
Verify all valves are installed in the proper location and
correctly orientated relative to the gas or air flow direction.
Prepare for Start Up/Adjustment
After installation of the burner system components is complete, the
following shall be followed to prepare for adjustment:
Close all the burner shut-off valves.
Try to light a burner before the purge and other timing relays
have finished their cycles. Verify that the flame monitoring
system indicates a flame failure.
Trip pressure switches and other limit interlocks. Verify that
the main gas valve train closes.
DANGER:
If simulated limits or simulated flame failures do not shut
down the fuel system with the required failure response time,
immediately correct the problem and retest before proceeding.
