Maintenance Report
CAUTION
In unusually dirty or dusty conditions, care must be taken to keep
boiler cabinet door in place at all times. Failure to do so VOIDS
WARRANTY!
WARNING
!
Allowing the boiler to operate with a dirty combustion chamber will
hurt operation. Failure to clean the heat exchanger as needed by the
installation location could result in boiler failure, property damage,
personal injury, or death. Such product failures ARE NOT covered
under warranty.
The combustion chamber insulation in this product contains ceramic
ber material. Ceramic bers can be converted to cristobalite in
very high temperature applications. The International Agency for
Research on Cancer (IARC) has concluded, “Crystalline silica inhaled
in the form of quartz or cristobalite from occupational sources is
carcinogenic to humans (Group 1).”
• Avoid breathing dust and contact with skin and eyes.
• Use a NIOSH certied dust respirator (N95). This type of
respirator is based on the OSHA requirements for cristobalite at
the time this document was written. Other types of respirators
may be needed depending on job site conditions. Current
NIOSH recommendations can be found on the NIOSH website:
http://www.cdc.gov/niosh/homepage.html. NIOSH approved
respirators, manufacturers, and phone numbers are also listed
on this website.
• Wear long-sleeved, loose tting clothing, gloves, and eye
protection.
• Apply enough water to the combustion chamber lining to
prevent dust.
• Wash potentially contaminated clothes separately from other
clothing. Rinse clothes washer thoroughly.
NIOSH stated First Aid.
• Eye: Irrigate immediately.
• Breathing: Fresh air.
The boiler requires minimal periodic maintenance under normal
conditions. However, in unusually dirty or dusty conditions, periodic
vacuuming of the cover to maintain visibility of the display and
indicators is recommended.
Periodic maintenance should be performed once a year by a qualied
service technician to assure that all the equipment is operating safely
and eciently. The owner should make necessary arrangements with
a qualied heating contractor for periodic maintenance of the boiler.
Installer must also inform the owner that the lack of proper care and
maintenance of the boiler may result in a hazardous condition.
WARNING
!
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.
CAUTION
It is very important that the condensate piping be no smaller than
¾”. To prevent sagging and maintain pitch, condensate piping
should be supported with pipe supports, and pitched ¼” per foot
to allow for proper drainage.
The condensate line must remain unobstructed, allowing free
ow 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.
6. Fill the condensate trap with fresh water prior to reassembly on
the boiler.
7. Install the condensate trap on the condensate hose from the
heat exchanger. Use the hose clamp to secure the trap. Attach the
clear plastic hose onto the hose barb. Reinstall the condensate hose
clamp to detach the condensate trap from the drain tube.
8. 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 the 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.)
9. Check condensate piping for sagging and/or leakage. Repair any
sags or leaks before restoring power to the boiler.
10. If the boiler has a condensate pump, ensure the pump operates
properly before considering maintenance complete.
