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 13 - 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
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
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,
WHL-016 Rev. 4.14.16
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.
