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 11 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 "Operate boiler," page 25.
❏
Proper burner flame? See "Check burner flame — Main
burner" and "Check burner flame — Pilot burner," page 26.
❏
Test temperature limit — While burners are operating, turn
Boiler Temp adjustment knob counterclockwise until display
reading is below actual boiler water temperature. Burners
should go off while circulator continues to operate (water
boilers only). Turn Boiler Temp adjustment knob clockwise
until display reading is above boiler water temperature and
ignition sequence should resume.
❏
Test any additional field-installed controls: If boiler has a 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:
Connect manometer to outlet side of gas valve. Start boiler, allow-
ing 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.

❏
Set Boiler Temp adjustment knob to system temperature
requirements. Adjust balancing valves and controls to pro-
vide design temperature to system. (water boilers)
❏
Limit control set to design temperature or pressure require-
ments of system? Maximum limit setting - 240°F - 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 20 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:
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"
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?
