safe, trouble free operation and maximum efficiency.
11 - GENERAL MAINTENANCE AND CLEANING
WARNING
Combustion chamber insulation in this product
contains ceramic fiber material. Ceramic fibers 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
(Group1). Avoid breathing dust and contact with
skin and eyes. Use NIOSH certified 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 the job site conditions. Current
NIOSH recommendations can be found on the NIOSH
http://www.cdc.gov/niosh/homepage.html.
NIOSH approved respirators, manufacturers, and
phone numbers are also listed on this website. Wear
long-sleeved, loose fitting 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.

WARNING
Before servicing, turn off electrical power to boiler
at service switch. Close manual gas valve to turn
gas supply OFF to boiler. Test for gas leaks on any
gas carrying components after servicing. Service
not complete until appliance operation verified per
Installation, Operation & Maintenance Manual provided
with boiler.
!
WARNING
Following service procedures must be performed by
qualified service agent. Boiler owner shall not attempt
these steps. Failure to do so could result in death or
serious injury.
!
CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation. Failure to follow these
instructions could result in minor or moderate injury.

11.2 Maintenance And Routine Servicing
Check and service boiler as necessary.
Frequency of servicing will depend upon installation conditions
and usage, manufacturer recommends annually.
• Check combustion is correct using combustion analyzer.
•
Check flue terminal outside and ensure it is not blocked.
• Operate boiler. Check operation of boiler's controls.
•
Ensure all system connections and fittings are sound.
Correct any joints and fittings that maybe leaking.
• Follow safety valve manufacturer recommendations for
service.
To ensure boiler operates at peak efficiency, following checks
must be performed every year:
• check appearance and tightness of gas and combustion
circuit gaskets
•
check condition and position of ignition and flame
sensing electrodes
• check condition of burner and its connection to
aluminum front plate
• check for dirt in combustion chamber. Use vacuum
cleaner for this cleaning operation
• check gas valve is calibrated correctly using
combustion analyzer
• check there is no dirt in condensate trap
• check central heating system pressure
• check expansion tank pressure
• check vent system, clean if necessary
Record details and maintain service history.
11.3 Component Replacement And Cleaning
1.
Remove any deposits from heat exchanger using suitable
soft brush.
Do not
use brush with metallic bristles.
2.
Check condition of the combustion chamber insulation
panels. Any damaged panels must be replaced.
3.
Check condition of burner. Clean burner with soft brush
and check flame ports are clear. Blockages may be
removed with stiffer brush. Do not use a brush with
metallic bristles this might damage the burner.
4.
Remove any fallen deposits from bottom of inner case.
5.
Check condition of electrodes.
6.
Check spark gap, positioning and height of electrodes.
7.
Check fan impeller is clean and free to rotate.
AFTER ANY COMPONENT REPLACEMENT OR
CLEANING AUTO CALIBRATION IS REQUIRED.
