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. If the boiler combustion air intake is located in any area likely to cause or contain contamination, or if products which would contaminate the air cannot be removed, the intake must be repiped and terminated to another location.

DO NOT re-pipe ventilation system on your own. Call a qualified service provider for assistance.

General



Attend to any reported problems.



Inspect the interior of the boiler jacket area; clean and vacuum if necessary.



Clean the condensate trap and fill with fresh water.



If applicable, check the condensate neutralizer and ensure it is full of condensate neutralizing marble chips.



Check for leaks: Water, gas, flue and condensate.



Verify exhaust vent and intake piping are in good condition and sealed tight.



Check exhaust vent and intake pipe bracing. Ensure bracing is undamaged and in good condition.



Check boiler water pressure, piping and expansion tank.



Check control settings.



Check ignition electrode. Sand off any white oxide. Clean and reposition.



Check ignition and ground wiring.



Check all control wiring and connections.



Check burner flame pattern (stable and uniform).

Additional Items if Combustion or Performance is Poor



Clean heat exchanger and flue ways.



Remove burner assembly and clean burner head using compressed air only.

Once the maintenance items are completed, the service technician should review service with the owner.

B. OWNER MAINTENANCE

Periodically



Check area around the boiler.
