VII Venting
WARNING
• Improper venting may result in property damage and/or the release of flue gases, which
contain deadly carbon monoxide (CO), into the home, which can cause severe personal
injury or death.
• Inspect existing chimney before installing boiler. Failure to clean or replace damaged pipe
or tile lining will cause property damage, severe personal injury or death.
• Do not de-rate the appliance. Failure to fire the unit at it’s designed input may cause
excessive condensation upon the interior walls of the chimney. In addition, the lower input
may not create enough draft to adequately evacuate the products of combustion.
• Do not omit the blanket when called for in the table above.
• Do not add any extra baffles beyond those prescribed for the model/burner combination
shown in Table 4.1.
Doing either of these things could cause accelerated chimney deterioration due to condensa-
tion or inadequate draft resulting in severe property damage, personal injury or death.
