7.3.3 Replacing the burner
Warning
The IBC heat exchanger has a small amount of combustion chamber insulation
(refractory), which contains ceramic fibers.
When exposed to extremely high temperatures, the ceramic fibers that contain
crystalline silica can be converted into cristobalite, classified as a possible human
carcinogen.
Avoid disturbing or damaging the refractory. If damage occurs, contact the factory for
directions.
Avoid breathing and contact with skin and eyes and follow these precautions:
1. For conditions of frequent use or heavy exposure, respirator protection is
required. Refer to the “NIOSH Guide to the Selection and Use of Particulate
Respirators Certified under 42 CFR 84” for selection and use of respirators
certified by NIOSH.
For the most current information, NIOSH can be contacted at 1-800-356-4676 or
on the web at www.cdc.gov/niosh.
2. Wear long sleeved, loose fitting clothing, gloves and eyes protection.
3. Assure adequate ventilation.
4. Wash with soap and water after contact.
5. Wash potentially contaminated clothes separately from other laundry and rinse
washing machine thoroughly.
6. Discard used insulation in an air tight plastic bag.
NIOSH stated first aid:
Eye contact - Irrigate and wash immediately.
Breathing - Provide fresh air.
1. Turn off the electric power and gas supply to the combi boiler.
2. Remove the front cover, then remove the four top panel Torx screws to remove the top
access panel.
Warning
Wear a suitable protective mask to avoid ingesting particles from the refractory.
3. Remove the electrical connection to the gas valve with a Philips head screwdriver.
