If cleaning is required:
a. Shut off all power to the boiler.
b. Expose the heat exchanger by removing the
draft hood (when equipped), and venting, top
assembly, ue collector, and heat exchanger
bafes.
c. Remove the burners by lifting them off the
orices and pulling them out of the boiler.
d. Use a hand-operated spray bottle lled with
water and a wire brush to clean any soot and
loose scale from the underside of the heat
exchanger. Do not use compressed air, high
pressure water or a garden hose.
e. Clean any fallen debris from the bottom of the
unit.
f. Check to make sure that the burner ports
and pilot assembly are free of debris before
returning the burners to their original
positions.
g. Reassemble the boiler in reverse order, making
sure to replace the heat exchanger bafes.
9. The gas and electric controls installed on the
boiler are engineered for both dependable
operation and long life, but the safety of this
equipment completely depends on their proper
functioning. For this reason, it is strongly
recommended that the basic items be checked by
a competent service technician every year and
replaced when necessary.
The basic controls are:
a. Water temperature controls
b. Pilot safety system
c. Automatic electric gas valve(s)
d. Flue or vent damper
10. The blocked vent safety switch is used to shut
the boiler down in the case of insufcient draft
due to venting system problems. Before resetting
the blocked vent safety switch see the Appendix
Figure 4 - Pilot Arrangements
1) Pilot
2) Main burner ame pattern
in Section 8D of the Installation and Operating
Instructions (Document number 1254) to ensure
that all possible causes have been investigated
and corrected. If the problem continues and the
boiler cannot be restored to normal operation call
a qualied service agency.
11. The ame rollout safety switch provides
additional safety, and will shut down the boiler
should the ame from the main burners rollout
(ashback) towards the main gas valve. Before
resetting the ame rollout switch, see Section 8D
of the Installation and Operating Instructions,
(Document H2355800) to ensure that all possible
causes have been investigated and corrected.
If the problem continues and the boiler cannot
be restored to normal operation call a qualied
service agency. Never attempt to bypass the
ame roll-out safety switch for the purpose of
operating the boiler.
Do not use this boiler if any part has been under
water. Immediately call a qualied service
technician to inspect the boiler and to replace any
part of the control system and any gas control
which has been under water.
12. Check all heat exchanger water connections,
ange or header gaskets for water tight integrity
24 hours after commissioning. If there are any
signs of water leakage, re-torque fasteners or re-
seat threaded connections as necessary
NOTE: After installation and rst start-up, check
the heat exchanger for fouling after the following
periods of operation:
24 hours 30 days
7 days 90 days+
Then once every six months thereafter.
Note: The warranty does not cover any damage
caused by lack of required maintenance or
improper operating procedures.
