A. GENERAL (WITH BOILER IN USE)
General boiler observation can be performed by the
owner. If any potential problems are found, a qualified
installer or service technician/agency must be notified.
1. Remove any combustible materials, gasoline and
other flammable liquids and substances that generate
flammable vapors from the area where the boiler is
contained.
2. Observe general boiler conditions (unusual noises,
vibrations, etc.)
3. Observe operating temperature and pressure on the
combination gauge located in the supply piping on the
left side of the boiler. Boiler pressure should never be
higher than 5 psi below the rating shown on the safety
relief valve (25 psig maximum for a 30 psig rating).
Boiler temperature should never be higher than 240° F.
4. Check for water leaks in boiler and system piping.
5. Smell around the appliance area for gas. If you
smell gas, follow the procedure listed in the Lighting

Product Safety Information
Refractory Ceramic Fiber Product
This appliance contains materials made from refractory ceramic fibers (RCF). Airborne
RCF fibers, when inhaled, have been classified by the International Agency for Research
on Cancer (IARC), as a possible carcinogen to humans. After the RCF materials have been
exposed to temperatures above 1800°F, they can change into crystalline silica, which has
been classified by the IARC as carcinogenic to humans. If particles become airborne during
service or repair , inhalation of these particles may be hazardous to your health.
Avoid Breathing Fiber Particulates and Dust
Suppliers of RCF recommend the following precautions be taken when handling these
materials:
Precautionary Measures:
Provide adequate ventilation.
Wear a NIOSH/MSHA approved respirator.
Wear long sleeved, loose fitting clothing and gloves to prevent skin contact.
Wear eye goggles.
Minimize airborne dust prior to handling and removal by water misting the material and
avoiding unnecessary disturbance of materials.
Wash work clothes separately from others. Rinse washer thoroughly after use.
Discard RCF materials by sealing in an airtight plastic bag.
First Aid Procedures:
Inhalation: If breathing difficulty or irritation occurs, move to a location with fresh clean air.
Seek immediate medical attention if symptoms persist.
Skin Contact: Wash affected area gently with a mild soap and warm water. Seek immediate
medical attention if irritation persists.
Eye Contact: Flush eyes with water for 15 minutes while holding eyelids apart. Do not rub
eyes. Seek immediate medical attention if irritation persists.
Ingestion: Drink 1 to 2 glasses of water. Do not induce vomiting. Seek immediate medical
attention.
