PART 2 – COMBUSTION AIR – CONTAMINATION PREVENTION Do not operate the boiler if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in Table 1. These areas will always contain hazardous contaminates that can form strong acids while passing through the burner and vent system. These acids will corrode the boiler’s heat exchanger, burner components and vent system, resulting in flue gas spillage and/or water leakage, possible substantial property damage, severe personal injury, or death.
B. OWNER MAINTENANCE Periodically • Check area around the boiler. • Check and remove any blockage from the outdoor exhaust vent and intake pipe terminations. DO NOT perform this maintenance if exhaust vent and intake pipe terminations are in difficult to reach locations. •...
B. MONTHLY MAINTENANCE Check Exhaust Vent and Intake Piping Visually inspect the exhaust vent for any signs of blockage, leakage, or deterioration of the piping. Inspect the exhaust vent bracing. Ensure bracing is undamaged and in good condition. Notify a qualified service technician immediately if any problems are found. Failure to inspect the venting system and have it repaired by a qualified service technician can result in vent system failure, causing severe personal injury or death.
