Part 3 - Maintenance Schedule
A. Service Technician
The following maintenance should be performed by a qualified
service technician annually:
General
•
Attend to any reported problems.
•
Inspect the interior of the appliance; 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 appliance 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 of Performance is Poor
• Clean heat exchanger and flue ways.
•
Remove burner assembly and clean burner head using
compressed air only.
The service technician should review service with the owner
after the maintenance items are completed.
B. Owner Maintenance
Periodically
•
Check area around the appliance.
•
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.
•
Check the temperature / pressure gauge.
Monthly
•
Check exhaust vent and intake piping.
•
Check exhaust vent and intake pipe bracing. Ensure
bracing is undamaged and in good condition.
•
Check the pressure relief valve.
Part 2 - Combustion Air Contamination Prevention
Do not operate the appliance 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 appliance’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 appliance 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 re-piped and terminated to another location.
DO NOT
re-pipe ventilation system on your own. Call a qualified
service provider for assistance.
