CARING FOR THE INFINITY

Maintenance
Even if there does not seem to be a problem with the water heater it is required in the UK
that all gas appliances are serviced every year by a certified gas engineer. This is to ensure
continued safety of the gas appliance. If you need a recommended service engineer contact
Rinnai or your supplier.
Care
When the appliance casing, operation panel, and remote controls surfaces become dirty
gently wipe them clean with a soft, damp cloth. Do not use detergents on these parts.
Filter
The water heater has a filter on the cold water inlet connection. This filter will need to be
cleaned occasionally. How often will be determined by the local water conditions. The water
filter can be located on the diagram on page 20. Isolate the cold water inlet and hot water
outlet with the valves near the heater. Release the pressure in the heater by unscrewing the
drain valve (shown on page 20.) Then remove the filter, clean it and replace it.
