PREVENTATIVE MAINTENANCE
Minor maintenance should be performed every six months by the dwelling occupant and a
major service should be performed every five years by a suitably qualified person.
Note:
The water heater is not fitted with frost protection and must be drained if freezing
conditions are likely to occur (refer to 'Frost Protection & Draining the Water Heater' on
page 7).
Only genuine replacement parts should be used on this water heater.
Minor Six Month Maintenance
1. Inspect around the air inlet / flue terminal and the water heater in general for plant
growth and trim back any shrubs or bushes that have encroached around the water
heater.
2. Inspect around the water heater for insect infestations such as ants. Spray insecticide
around the water heater if necessary to rid the area of insects. Do not spray the water
heater surface or into the air inlet / flue terminal of the water heater.
Do not spray around the water heater with insecticide while the water
heater is operating. Propellants in insect spray may contain hydrocarbon
which can catch fire. Close the cold water isolation valve to the water
heater to prevent the water heater from operating while you spray around
the water heater. Open the cold water isolation valve when finished.
3. If required, clean the water heater with a soft cloth and warm mild soapy water. Under
no circumstances should abrasive materials, powders or chemicals be used.
4. Check to ensure the drain line from the safe tray (if one is installed) is not blocked.
5. Check heater operation.
6. Warn customer of the danger of storing chemicals and/or using flammable materials or
aerosol spray packs near the heater. Aerosols and harsh chemicals can also cause
premature failure of heater components.
Major Five Year Service
Servicing must be performed by a suitably qualified person.
1. Conduct the Minor Six Month Maintenance procedure detailed above PLUS;
2. Remove and clean cold water inlet strainer (refer to component replacement
procedure 15 on page 55).
3. Remove and clean burner (refer to component replacement procedure 10 on page 53).
4. Check and if necessary adjust the burner gas pressure (refer to 'Checking & Adjusting
the Burner Gas Pressure' on page 47).
5. Inspect all plumbing connections and components for leaks.
6. Inspect all electrical connections.
7. Visually inspect the water heater for any potential problems.
DO NOT return the heater to service if any test/check result is outside
specifications or if an unsafe condition exists.
