Check-out procedure, Each zone water boilers only?

8	EG, PEG, EGH GAS-FIRED BOILERS — SERIES 4 — BOILER MANUAL

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.

❏Testlimitcontrol:Whileburnersareoperating,movelimitcontrol 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).

❏Limitcontrolsettodesigntemperatureorpressurerequirements 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	= Btuh

number of seconds from step c

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?
