OPERATIONS & MAINTENANCE
A. PLACING BOILER IN OPERATION
1. Start up the boiler per the Lighting Instructions
shipped with the boiler.
2. Prove the correct operation of all controls on the
boiler as outlined below.
3. Check the operation of the ignition and flame
proving controls:
a. Electronic Spark-Ignited Pilot System (S8610M
Control)
• With the boiler operating, close the Pilot
manual shut-off valve.
• The ignition control should close the main
gas valves within 1 second.
• The control will spark and attempt to relight
the pilot burner.
• After 15 seconds, the control will shut down
and wait 5 to 6 minutes for another ignition
trial.
• Open the Pilot manual shut-off valve and re-
start the boiler per the Lighting Instructions.
(Standing pilots will have to be manually re-
lit per the Lighting Instructions.)
b. Electronic Standing Pilot System
• With the boiler operating, close the Pilot
manual shut-off valve.
• The ignition control should close the main
gas valves within 3 seconds after the pilot
goes out.
• After 15 seconds, the control will lock out.
• Open the Pilot manual gas shut-off valve and
re-start the boiler per the Lighting
Instructions. (Standing pilots will have to be
manually re-lit per the Lighting Instructions.)
4. Check the manifold gas pressure and use a soap suds
mixture to check the gas tightness of all gas joints.
5. Test the limit and operating controls to assure they
are operating correctly.
6. Inspect and test all low water cut-offs. (Float type
controls must be flushed (blown down) weekly to
remove any sediment from the float chamber.)
7. Test the pop safety relief valve(s) using the procedure
given by the valve manufacturer on the valve tag.
8. Visually inspect the burner and pilot flames.
a. See Figure 12.1.
b. The flame inner cone should be about 1-1/2"
(4 cm) high and should have a very sharp, blue
color characteristic.
c. Poor flame conditions can be caused by dirty
burners, obstructed orifices, or incorrect gas
pressure.
Figure 12.1: Pilot and Burner Flames
Do not store or allow combustible or flammable
materials near the boiler. Substantial fire or explosion
hazard could result, causing risk of personal injury,
death or property damage.
Do not use this boiler if any part of it has been under
water. Immediately call a qualified service technician
to inspect the boiler. Any part of the control system,
any gas control or any burner or gas component
which has been under water must be replaced.
Should overheating occur or the fuel supply fail to
shut off: Shut off the fuel supply at a location
external to the boiler. Do not turn off or disconnect
the electrical supply to the pump. Immediately call a
qualified service technician to inspect the boiler for
damage and defective components.
