Check-out procedure
Check-off steps as completed.
❏
System properly filled with water?
❏ Automatic air vent, if used, open one turn (water boilers only)?
❏ Air purged from system (water boilers only)?
❏ Steam boilers properly skimmed?
❏ Air purged from gas piping?. Piping checked for leaks?
❏ Are proper orifices installed? Check page 7 for proper size.
Proper orifices must be used. Failure to do so will cause
severe personal injury, death or substantial property
damage.
❏ Follow operating instruction label on boiler for proper start-
up. Also refer to “To Place in Operation,” page 17.
❏ Proper burner flame? Refer to “Check Main Burner Flames”
and “Check Pilot Burner Flame,” page 21.
❏ Test limit control: While burners are operating, move limit control
indicator below actual boiler water temperature or pressure.
Burners should go off. Circulator should continue to operate
(water boilers only). Raise indicator above boiler water
temperature or pressure and burners should reignite.
❏ Test any additional field-installed controls: If boiler has low
water cut-off, additional high limit or other controls, test for
operation as outlined by manufacturer. Burners should be
operating and should go off when controls are tested. When
controls are restored, burners should reignite.
❏ EG only - button on spill switch pushed in?
❏ To test ignition system shut-off device:
a. For boilers with electronic ignition systems: Connect
manometer to outlet side of gas valve. Start boiler, allowing for
normal start-up cycle to occur and main burners to ignite. With
main burners on, manually shut off gas supply at manual main
shutoff 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 element will sense pilot
flame and main burners reignite.
b. For standing pilot - Turn 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 17).
❏ Limit control set to design temperature or pressure requirements
of system? Maximum limit setting - 240°F (water boilers) - 15#
(steam boilers).
❏ For multiple zones, flow adjusted so it is about the same in
each zone (water boilers only)?
❏ Thermostat heat anticipator set properly? Refer to “Room
Thermostat,” page 15 and correct wiring diagram.
❏ Boiler cycled with the thermostat? Raise to highest setting. Boiler
should go through normal start-up cycle. Lower to lowest
setting. Boiler should go off.
❏ Measure gas input (natural gas only):
a. Operate boiler 10 minutes.
b. Turn off other appliances.
c. At the natural gas meter, measure time (in seconds) required to
use one cubic foot of gas.
d. Calculate gas input:
3600 x 1000
number of seconds from step c
= Btuh
e. Btuh calculated should approximate input rating on rating
label.
❏ Check manifold gas pressure by connecting a manometer to
the downstream test tapping on main gas valve.
MANIFOLD GAS PRESSURE
NAT. = 3.5" W.C.
L.P. = 10.0" WC.
❏ Several operating cycles observed for proper operation? If
damper is provided, see Control Supplement for check- out
procedure.
❏ Room thermostat set to desired temperature?
❏ Installation and Service Certificate on this page completed?
❏ All instructions shipped with this boiler reviewed with owner
or maintenance person, returned to envelope and given to
owner or displayed near boiler?
