GOLD CGs Gas-Fired Water Boiler

8Check-out procedure — checklist

❏Boiler and heat distribution units filled with water?

❏Automatic air vent, if used, open one full turn?

❏Air purged from system?

❏Air purged from gas piping? Piping checked for leaks?

❏Correctly sized manifold orifices installed? Refer to manual section 2a to check size and fuel type.

Correctly sized manifold orifices must be used. Failure to do so will cause severe personal injury, death or substantial property damage.

❏Followed operating instructions on boiler or in manual section 9 for proper start-up?

❏Proper burner flame observed? Refer to Check burner flame, manual section 7b.

❏Test limit control — While burners are operating, move indicator on limit control below actual boiler water temperature. Burners should go off while circulator continues to operate. Raise setting on limit control above boiler water temperature and burners should reignite.

❏Test additional field-installed controls — If boiler has a low water cutoff, 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.

❏Test ignition system safety device:

a.Connect manometer to outlet side of gas valve.

b.Start boiler, allowing for normal start-up cycle to occur and main burners to ignite.

c.With main burners on, manually shut off gas supply at manual main shutoff gas valve. Burners should go off.

d.Open manual main shutoff gas valve. Manometer should confirm there is no gas flow.

e.Pilot will relight, flame sensing element will sense pilot flame and main burners will reignite.

❏Set limit control(s) to system temperature requirements. Adjust balancing valves and controls to provide design temperature to system.

❏For multiple zones, adjust flow so it is about the same in each zone.

❏Verify thermostat heat anticipator (if available) set properly? Refer to Field wiring, manual section 6a, Thermostat(s).

❏Cycle boiler with thermostat — Raise to highest setting and verify boiler goes through normal start-up cycle. Lower to lowest setting and verify boiler goes off.

❏Measure natural gas input:

a.Operate boiler 10 minutes.

b.Turn off other appliances.

c.At 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 boiler rating label.

❏Check manifold gas pressure by connecting manometer to downstream test tapping on main gas valve. Manifold pressure for natural gas should be 3.5" w.c. and for propane gas should be 10" w.c.

❏Observe several operating cycles for proper operation.

❏Set room thermostat to desired room temperature.

❏Fill in Installation and service certificate below?

❏Review all instructions shipped with this boiler with owner or maintenance person. Return instructions to envelope and give to owner or place in pocket inside front panel in boiler.
