GOLD CGt Gas-Fired Water Boiler — Boiler Manual

Check-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 page 1
to check size.
Correctly sized manifold orifices must be used.
Failure to do so will cause severe personal in-
jury, death or substantial property damage.
❏ Followed operating instructions on boiler or in manual Sec-
tion 9 for proper start-up?
❏ Proper burner flame observed? Refer to
manual Section 7b .
❏ Test limit control — While burners are operating, move indi-
cator 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 tankless heat low limit control — While burners are
operating, move indicator on low limit control above actual
boiler water temperature. The 3-way valve should operate to
bypass all flow around the boiler. If low limit and valve operate
correctly, turn setting on low limit back to normal. The 3-way
valve should return to normal position.
❏ 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 ambient
temperature switch by disconnecting one of the wires from
the switch. Boiler shut down until wire is replaced.
❏ 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 tem-
perature 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
stat .
,
❏ 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) re-
quired to use one cubic foot of gas.
d. Calculate gas input:
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.
❏ 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.
❏ Installation instructions have been followed.
❏ Check out sequence has been performed.
❏ Above information is certified to be correct.
