NOTE: These instructions are provided to ensure
the proper installation and operation of Raypak
boilers. Should questions arise regarding the
specifications, installation, operation or servicing of
these boilers, we suggest that the local Sales
representative or the factory be consulted.
WARNING: This unit contains refractory ceramic
fiber (RCF) insulation in the combustion chamber.
RCF, as manufactured, does not contain respirable
crystalline silica. However, following sustained
exposure to very high temperatures (>2192F), the
RCF can transform into crystalline silica
(cristabolite). The International Agency for Research
on Cancer (IARC) has classified the inhalation of
crystalline silica (cristabolite) as carcinogenic to
humans.
When removing the burners or heat exchangers,
take precautions to avoid creating airborne dust and
avoid inhaling airborne fibers. When cleaning spills,
use wet sweeping or High Efficiency Particulate Air
(HEPA) filtered vacuum to minimize airborne dust.
Use feasible engineering controls such as local
exhaust ventilation or dust collecting systems to
minimize airborne dust. Wear appropriate personal
protective equipment including gloves, safety
glasses with side shields, and appropriate NIOSH
certified respiratory protection, to avoid inhalation of
airborne dust and airborne fiber particles.
WARNING: To minimize the possibility of improper
operation, serious personal injury, fire, or damage to
the heater:
• Always keep the area around the heater free of
combustible materials, gasoline, and other flam-
mable liquids and vapors.
• Heater should never be covered or have any
blockage to the flow of fresh air to the heater.
WARNING: Do not use this heater if any part has
been under water. Immediately call a qualified
service technician to inspect the heater and to
replace any part of the control system and any gas
control which has been under water.
WARNING: Should overheating occur or the gas
supply valve fail to shut, do not turn off or disconnect
the electrical supply to the heater. Instead, shut off
the gas supply at a location external to the heater.
DANGER: Make sure the gas on which the heater
will operate is the same type as that specified on the
heater rating plate.
