• Installation • Start-Up • Maintenance • Parts
1. System properly filled with water?
2. Automatic air vent, if used, open one turn (water boilers only)?
3. Air purged from system (water boilers only)?
4. Steam boilers properly skimmed?
5. Air purged from gas piping? Piping checked for leaks?
6. Are proper orifices installed? See
Control Supplements
for orifice sizes.
7. Follow
Control Supplement
and operating instruction label on boiler for proper start-up. Also refer to
Section 8, Placing boiler in operation
, page 26.
8. Proper burner flame? Refer to
Check Pilot Burner Flames
and
Check Main Burner Flame
,
Section 10
, page 30.
9. Test limit control — While burners are operating, move the indicator of the limit control below actual boiler
water temperature or pressure. Burners should go off. The circulator should continue to operate (water
boilers only). Raise the limit control above boiler water temperature or pressure and burners should reignite.
10. Test any additional field-installed controls — If boiler has low water cutoff or additional high limit or other
controls, test for operation as outlined by the manufacturer. Burners should be operating and should go off
when controls are tested. When controls are reset, burners should reignite.
11. Test ignition shutoff device — Turn off gas at manual main gas valve. Connect 24 VAC leads across PV and
MV/PV terminals on pilot proving control module. Establish call for heat. Pilot solenoid valve will close
within 15 seconds and remain off for minimum 5 minutes, then retry for ignition. Reset system by turning
off and on the main electrical switch.
12. Limit control set to design temperature or pressure requirements of system?
13. For multiple zones, flow adjusted so it is about the same in each zone (water boilers only)?
14. Boiler cycled with operating control? Raise to highest setting. Boiler should go through normal start-up
cycle. Lower to lowest setting. Boiler should turn off.
15. Measure gas input (natural gas only):
a. Operate boiler 10 minutes.
b. Turn off all other appliances.
c. At the natural gas meter, measure cubic feet of gas in ten seconds.
d. Calculate gas input:
•
Btuh = 1000 x (3600 x CFH)/10
e. Btuh calculated should approximate input rating on rating plate.
16. Check manifold gas pressure by connecting a manometer to the downstream test tapping on main gas valve.
•
Manifold gas pressure = 3.5" w.c. for
natural gas
.
•
Manifold gas pressure = 10" w.c. for
propane gas
.
17. Several operating cycles observed for proper operation?
18. Operating control set to the design requirement?
19.
