Do not operate the boiler without the clear hose attached from
the hose barb to the pressure switch. Failure to follow this warning
could result in property damage, serious personal injury, or death.
10. If a condensate neutralizer kit is installed with the boiler, check
the assembly when cleaning the condensate trap, and replenish the
limestone chips if necessary. When replacing limestone chips, take
care to ensure chips are no smaller than ½” to avoid blockage in
condensate piping (for piping details, refer to condensate neutralizer
installation instruction.)
11. Check condensate piping for sagging and/or leakage. Repair any
sags or leaks before restoring power to the boiler.
It is very important that the condensate piping be no smaller than
1/2”. To prevent sagging and maintain pitch, condensate piping
should be supported with pipe supports, and pitched ¼” per foot
to allow for proper drainage. Failure to maintain proper pipe size
and pitch could result in condensate leakage and potential water
damage to property.
The condensate line must remain unobstructed, allowing free flow of
condensate. If condensate freezes in the line, or if line is obstructed
in any other manner, condensate can exit from the tee, resulting in
potential water damage to property.
11. If the boiler has a condensate pump, ensure the pump operates
properly before considering maintenance complete.
Part 14 - Shutdown
A. Shutdown Procedure
If the burner is not operating, disconnect the electrical supply.
If the burner is operating, lower the set point value to 70
o
F and wait for
the burner to shut off. Continue to wait for the combustion blower to
stop, so all latent combustion gases are purged from the system. This
should take a maximum of 40 to 90 seconds.
B. Vacation Procedure
If there is danger of freezing, change the set point to 70
o
F. DO NOT turn
off electrical power. If there is no danger of freezing, follow “Shutdown
Procedure”.
C. Failure to Operate
Should the burner fail to light, the control will perform two more
ignition trials prior to entering a lockout state. Note that each
subsequent ignition trial will not occur immediately. After a failed
ignition trial, the blower must run for approximately 10 seconds to
purge the system. Therefore, a time period of approximately 40 to 90
seconds will expire between each ignition trial.
If the burner lights during any one of these three ignition trails, normal
operation will resume. If the burner lights, but goes off in about 4
seconds, check the polarity of the wiring. See electrical connection
section.
If the burner does not light after the third ignition trial, the control
will enter a lockout state. This lockout state indicates that a problem
exists with the boiler, the controls, or the gas supply. Under such
circumstances, a qualified service technician should be contacted
immediately to properly service the boiler and correct the problem. If
a technician is not available, depressing and holding the RESET button
for more than 1 second will remove the lockout state so additional
trials for ignition can be performed. The unit will try to re-light once
every 6 minutes.
D. Important Notice
It is extremely important that whenever work is performed on the
plumbing system that either:
• The appliance is powered off, or,
• The appliance is valved off and isolated from the plumbing
system.
Failure to take these measures could result in a dry-firing condition.
