WARNING
syncFURNACE OD Instruction & Installation Manual – Rev 09
Replace any gaskets, seals or refractory that shows any signs of damage. DO NOT
REUSE. Failure to follow these instructions may result in fire, property damage or death.
Refractory Ceramic Fibers (RFC)
Personal Protective Equipment Required – Read the following warnings and handling
instructions carefully before commencing any service work in the combustion chamber.
The insulating material on the inside of the burner door and at the back of the
combustion chamber contain Refractory Ceramic Fibers and should not be handled
without personal protective equipment.
POTENTIAL CARCINOGEN – Use of Refractory Ceramic Fibers in high temperature
applications (above 1000°C) can result in the formation of Crystalline Silica
(cristobalite), a respirable silica dust. Repeated airborne exposure to crystalline silica
dust may result in chronic lung infections, acute respiratory illness, or death. Crystalline
silica is listed as a (potential) occupational carcinogen by the following regulatory
organizations: International Agency Research on Cancer (IARC), Canadian Centre for
Occupational Health and Safety (CCOHS), Occupational Safety and Health Administration
(OSHA) and National Institute for Occupational Safety and Health (NIOSH). Failure to
comply with handling instructions may result in serious injury or death.
CRYSTALLINE SILICA – Certain components confined in the combustion chamber may
contain this potential carcinogen. Improper installation, adjustment, alteration, service
or maintenance can cause property damage, serious injury (exposure to hazardous
materials) or death. Installation and service must be performed by a qualified installer,
service agency or the gas supplier.
See APPENDIX D for handling instructions for Refractory Ceramic Fibers (RCF).
