WARNING
Asphyxiation Hazard. The outlet pressure for the gas valve has been factory set and requires no eld
adjustment. This setting is satisfactory for both natural gas and propane. Attempting to adjust the
outlet pressure may result in damage to the gas valve and cause property damage, personal injury or
loss of life due to carbon monoxide (CO) poisoning.
WARNING
Asphyxiation Hazard. Each boiler is tested at the factory and adjustments to the air-fuel mixture
are normally not necessary when operating on natural gas at sea level. Consult the factory before
attempting to make any such adjustments. Improper gas valve or mixture adjustments could result in
property damage, personal injury or loss of life due to carbon monoxide (CO) poisoning.
