checked for looseness caused during shipment.
Check:
a. Electrical terminals in the control panel and on all electrical components.
b. Pipe fittings and unions.
c. Tubing connections.
d. Nuts, bolts, screws.
2. Open all necessary oil shutoff valves. Do not run pumps or fuel unit without oil.
3. Before connecting electrical current to any component, be sure the voltage is the same as that specified on component name-
plates.
4. Before burner operation, be sure all motors are rotating in the proper direction.
5. Before firing, make sure the burner firing head and dry areas of the boiler are protected with refractory. The burner mounting
flange must be properly sealed against the vessel front plate.
6. Make certain that the operator in charge is properly instructed in operation and maintenance procedures.
BEFORE OPENING THE MANUAL GAS SHUTOFF VALVES, READ THE REGULATOR INSTRUCTIONS CAREFULLY. THE IN-
STRUCTIONS ARE IN THE REGULATOR BOX. FOLLOW THE MANUFACTURER RECOMMENDATIONS. OPEN SHUTOFF
VALVE ON THE INLET SIDE OF THE REGULATOR SLOWLY AND CAREFULLY TO ALLOW INLET PRESSURE TO BUILD UP
