SECTION P: POST START-UP CHECK
Check off steps as completed:
1. Boiler and heat distribution units or storage tank filled with water?
2. Automatic air vent, if used, open two full turns during venting procedure?
3. Air purged from system?
4. Air purged from gas piping? Piping checked for leaks?
5. Followed start-up procedure for proper start-up?
6. Is burner flame visible?
7. Test safety controls: If boiler is equipped with a low water cutoff or additional safety controls, test for operation as
outlined by manufacturer. Burner should be operating and should go off when controls are tested. When safety devices
are restored, burners should reignite after pre-purge time delay.
8. Test limit control: While burner is operating, move indicator on high limit control below actual boiler water
temperature. Burner should go off while blower circulator continues to operate. Raise setting on limit control above
boiler water temperature and burner should reignite after pre-purge time delay.
9. Test ignition system safety device:
• Turn power off.
• Close the pilot manual valve.
• Turn power on; after about 45 seconds of pre-purge, the pilot comes on. The pilot (and therefore the burner) should fail
to light. The standard lockout time is 90 seconds; then the pilot light goes off and the boiler goes into post-purge. (If
the lockout module is attached to boiler, a lockout light comes on.)
• Turn the power off; open the pilot manual valve; (reset the lockout module if applicable).
• Wait 30 seconds, then turn power on. The burner should ignite after pre-purge time delay.
10. To restart system, follow lighting instructions in Section O.
11. High limit control set to design temperature requirements of system?
For multiple zones: flow adjusted as required in each zone?
12. Boiler cycled with thermostat? Raise to highest setting and verify boiler goes through normal start-up cycle.
Reduce to lowest setting and verify boiler goes off.
13. Observed several operating cycles for proper operation?
14. Set room thermostat or tankstat to desired temperature?
15. Reviewed all instructions shipped with this boiler with owner or maintenance personnel, returned to envelope
and given to owner or placed in pocket inside front panel on boiler?

3.5 Follow-up
• Safety checks must be recorded as performed;
• Turn unit on;
• After main burner ignition. Check Manometers for proper readings;
• Verify that the blower shutter is locked;
• Cycle unit several times and recheck readings;
• Re-analyze with unit running record or print results;
• Turn unit off, remove all Manometers and replace blower switch hose, replace all gas pressure caps and plugs;
• Check for gas leak one more time;
• Check around unit for debris and remove combustible and flammable products, i.e. paper, gasoline etc.
