Confirm that all water, gas and electricity are
turned off.
Inspect the boiler combustion chamber for foreign
objects and remove if present,
Check physical condition of burners and pilot. Make
certain that there are no unusual bends or
perforations in the burners or pilot. Replace
components if necessary.
Verify that water piping, venting, gas piping and
electrical wiring and components are installed
properly. Refer back to previous sections of these
instructions as well as equipment manufadurer's
instructions as necessary.
Fill the boiler and system with water, making certain
to vent all air from all points in the system. To check
water level in the system, open and close each vent
in the system. Water should exit from each vent
when it is opened.
The pressure reducing valve on the fill line will
typically allow the system to be filled and pressurized
to 12 psi. Consult the valve and expansion tank
manufacturer for more specific information.
7 Check joints and fittings throughout the system for
leaks. If leaks are found, drain the system and repair
as required
8. Connect a manometer to the I/8" npt inlet pressure
tap on the gas valve. See Figure 20.
9.
Confirm that the gas supply pressure to the boiler is
above the minimum and below the maximum values
for the gas being used. See the end of Section 5 for
these values. If a supply pressure check is required,
isolate the boiler and gas valve before performing
the pressure check. If the supply pressure is too high
or too low, contact the gas supplier.
10. Turn on electricity and gas to boiler
11, Light the boiler by following the Lighting/Operating
Instructions label mounted to the jacket panel. The
initial ignition may require several tries as the piping
is purged of air.
12. Use the sequence description and Figure 16 in
Section 6 (Electrical) to follow light-off and shutdown
sequences and to assist in diagnosing problems. If
the boiler does not function properly, consult Section
8. Troubleshooting.
