NORMAL OPERATIONAL CHARACTERISTICS

During the initial burning in period some fumes and smell may be experienced. This condition may last for a couple
of hours, however this is a normal part of the burning-in process. We recommend to ventilate the space for this
period.
When using the heater for the first time, or after a long period of non-use, ignition may not occur the first time it is
operated due to air in the gas pipes. If ignition does not occur the unit will switch off automatically. Try operating
the heater again. If this condition persists however, contact Rinnai for advice.
The heater may make noises after ignition or switching off. This is due to thermal expansion and contraction of the
internal components and is normal.
As a safety precaution the heater will not ignite if the Standby / ON button is pressed immediately after the heater
has been turned off. It will take approximately 20 seconds for the unit to reset and switch back on again.
