General
• Attend to any reported problems.
• Inspect the interior of the water heater cabinet; 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 water heater 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.
2. OWNER MAINTENANCE
Periodically
• Check area around the water heater.
• 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.
• Check the condensate drain system.
• If applicable, check the condensate neutralizer and ensure it is full of condensate neutralizing marble chips.
Every 6 Months
Check water heater piping and gas supply piping for corrosion or signs of potential leakage.
The water heater must be inspected and serviced annually, preferably at the start of the heating season, by a qualied service technician. In
addition, the maintenance and care of the water heater as outlined in this manual must be performed by the user/owner to assure maximum

▪ C. MAINTENANCE PROCEDURES
1. DAILY MAINTENANCE
Check the Surrounding Area
Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other flammable vapors or liquids near the water heater. If found, remove these materials
immediately
.
Air Contaminates
If allowed to contaminate combustion air, products containing chlorine or fluorine will produce acidic condensate that will cause significant
damage to the water heater. Read the list of potential contaminates and areas likely to have these contaminates in Table 1, Part 2. If
any of these contaminates are in the room where the water heater is located, or combustion air is taken from one of the areas listed, the
contaminates must be removed immediately or the intake pipe must be relocated to another area.
