Section VII: Check-out Procedure
Check-off steps as completed.
□ ■ 1. Boiler and heat distribution units filled with water?
□
2. Automatic air vent, if used, open one turn?
□
3. Air purged from system?
□
4. Air purged from gas piping? Piping checked for leaks?
□
5. Are proper orifices installed? Check page 5 for proper
DANGER
Proper orifices must be used.
Failure to do so will cause se¬
vere injury, death or substan¬
tial property damage.
□
6. Follow operating/lighting instruction label on boiler
for proper start-up. Also refer to "lb Place in Opera¬
tion," page 11.
O
7. Proper burner flame? Refer to "Check Burner Flames,"
page 12.
□
8. Tfest limit controls: While burners are operating, move
indicator of high limit control below actual boiler
water temperature. Burners should go off while cir¬
culator continues to operate. Raise limit control above
boiler water temperature and burners should reignite.
□
9. Tfest any additional field-installed controls: If boiler
has low water cut-off, additional high limit or other
controls, test for operation as outlined by manufac¬
turer. Burners should be operating and should go off
when controls are tested. When controls are restored,
burners should reignite.
□ 10. Button on spill switch pushed in?
□ 11. Tfest ignition system shut-off device:
a. For standing pilot - TUm gas cock knob to PILOT
position and extinguish pilot flame. Pilot gas flow
should stop in less than 3 minutes. Put system back
into operation (see page 11).
b. For intermittent- ignition systems - Connect ma¬
nometer to outlet side of gas valve. Start boiler, al¬
lowing for normal start-up cycle to occur and main
burners to ignite. With main burners on, manually
shut off gas supply at manual main shut-off gas
valve. Burners should go off. Open manual main
shut-off gas valve. Manometer should confirm there
is no gas flow. Pilot will relight, flame sensing ele
ment will sense pilot flame and main burners re¬
ignite.
□ 12. High limit control set to design temperature require
ments of system? Maximum high limit setting is 240°F
□ 13. For multiple zones, flow adjusted so it is about th<
same in each zone?
□ 14. Thermostat heat anticipator set properly? Refer t(
"Install Room Thermostat" page 10, and wiring dia
gram on jacket door.
□ 15. Boiler cycled with thermostat? Raise to highest set
ting. Boiler should go through normal start-up cycle
Lower to lowest setting. Boiler should go off.
□ 16. Measure gas input (natural gas only):
a. Operate boiler 10 minutes.
b. T\im off other appliances.
c. At natural gas meter, measure time (in seconds
required to use one cubic foot of gas.
d. Calculate gas input:
3600x1000
— —
——
=
Btuh
number of seconds from step C
e. Btuh calculated should approximate input ratinj
on rating label.
□ 17. Check manifold gas pressure by connecting manome
ter to downstream test tapping on main gas valve
Manifold gas pressure for natural gas should be 3
V
inches water column and for propane gas should be 1(
inches water column.
D
18. Several operating cycles observed for proper operation-
See Control Supplement for damper check-out procedure.
□ 19. Room thermostat set to desired room temperature?
□ 20. Installation and Service Certificate on this page com
pleted?
□ 21. All instructions shipped with this boiler reviewed witl
owner or maintenance person, returned to envelop
and given to owner or displayed near boiler?
