INSTALLATION
THIS WATER HEATER IS FOR INDOOR INSTALLATION ONLY. THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. Check the water heater is suitable for the gas type available (refer to the rating label on the water heater).
Note: The 620 130 heavy duty water heater is designed for small commercial applications requiring sanitising temperatures and has a maximum temperature setting of 80°C. This model should not be installed in a domestic residence.
WATER HEATER LOCATION
The water heater should be installed close to the most frequently used outlet and its position chosen with safety and service in mind. Make sure people (particularly children) will not touch the flue outlet.
Clearance must be allowed for servicing of the water heater. The water heater must be accessible without the use of a ladder or scaffold. Make sure the temperature pressure relief valve lever is accessible and the front cover and burner can be removed for service.
You must be able to read the information on the rating plate. If possible leave headroom of one water heater length so the anode can be inspected or replaced. Remember you may have to remove the entire water heater later for servicing.
The installation must comply with the requirements of AS/NZS 3500.4, AS 5601 and all local codes and regulatory authority requirements. In New Zealand, the installation must conform with NZS 5261 Code of Practice for Installation of Gas Burning Appliances and the New Zealand Building Code.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or where aerosol propellants are released. Remember the air may be safe to breathe, but when it goes through a flame, chemical changes take place which may attack the water heater.
A secondary flue must be installed with an indoor water heater to discharge combustion products outside the building. The flue must be self supporting and not impose a load on the water heater. Use a slip joint or similar to allow for disconnection. There must be a vertical rise of 600 mm from the draught diverter before changing direction. The flue design and installation must comply with AS 5601.
