Warning - Smith Cast Iron Boilers GB300 Installation & Operating Manual

Any appliance that burns natural gas, propane gas, fuel oil, wood or coal is capable of producing carbon
monoxide (CO).
Carbon Monoxide (CO) is a gas which is odorless, colorless and tasteless but is very toxic.
If your Smith boiler is not working properly, or is not vented properly, dangerous levels of CO may accumulate.
CO is lighter than air and thus may travel throughout the building. BRIEF EXPOSURE TO HIGH
CONCENTRATIONS OF CO, OR PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY RESULT IN
CARBON MONOXIDE POISONING.
EXPOSURE CAN BE FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY RESULT IN THE
SUDDEN ONSET OF SYMPTOMS INCLUDING UNCONSCIOUSNESS.
Symptoms of CO poisoning include the following:
dizziness
headaches
nausea
The symptoms of CO poisoning are often confused with those of influenza, and the highest incidence of poisoning
occurs at the onset of cold weather or during flu season. A victim may not experience any symptoms, only one
symptom, or a few symptoms. Suspect the presence of carbon monoxide if symptoms tend to disappear when
you leave your home.
The following signs may indicate the presence of carbon monoxide:
• Hot gases from appliance, venting system, pipes or chimney, escaping into the living space.
• Flames coming out around the appliance.
• Yellow colored flames in the appliance.
• Stale or smelly air.
• The presence of soot or carbon in or around the appliance.
• Very high unexplained humidity inside the building.
If any of the symptoms of CO poisoning occur, or if any of the signs of carbon monoxide are present, VACATE
THE PREMISES IMMEDIATELY AND CONTACT A QUALIFIED HEATING SERVICE COMPANY OR THE GAS
COMPANY OR THE FIRE DEPARTMENT.
To reduce the risk of CO poisoning, have your heating system "tuned up" by a licensed heating contractor or the
gas company - preferably before each heating season. Also have the service company check your chimney or
vent pipes for blockage.
Your home should also be adequately ventilated, particularly if you have insulated your home.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS
SHOULD PERFORM WORK ON YOUR SMITH BOILER!
WARNING: Install, operate and maintain unit in accordance with manufacture's instructions to avoid
exposure to fuel substances or substances from incomplete combustion which can cause death or
serious illness. The State of California has determined that these substances may cause cancer, birth
defects, or other reproductive harm. Also, install and service this product to avoid exposure to airborne
particles of glasswool fibers and/or ceramic fibers known to the State of California to cause cancer
through inhalation. The ceramic combustion chamber in the burner box and its gasket contain crystalline
silica. Wear a tightly fitted dust mask when servicing the burner and gently handle the burner and its
gasket to prevent inhalation of airborne fibers. Crystalline silica fibers have been identified as
carcinogenic, or possibly carcinogenic when inhaled.
