operating and installation manual set carefully to verify that
the boiler is properly set up for operation. Check that all

have been correctly installed. Verify the supply of fuel. Check
to make sure the burner is wired as shown on the wiring
diagram. Ensure that all control wiring terminals are tight.
Complete the following checklist in preparation for system
startup:
• Confirm that the fuel and electrical connections have
been completed in accordance with the applicable codes
and insurance requirements (if necessary), and that con

nections comply with the piping schematic and wiring
diagram.
• Check the combustion air fan motor for correct rota-
tional direction.
• Check that the boiler is filled with water to the proper
level, and that all circulating pumps (hot water units) are
correctly installed and operational.
• Verify that there is proper gas pressure at the gas train,
