I have a Rinnai Sapphire RIB2310MN/A. When I turn it on it

Customer Question

I have a Rinnai Sapphire RIB2310MN/A . When I turn it on it lights then goes out after about 30 seconds. When we don't use it for about 2 days it works fine again for about a day and the problem happens again. What could be causing this to happen?

Have you noticed ABNORMAL FLAME PATTERN upon startup like flame lifting and clouding up then blow out completely ?

I flame looks normal and it just shuts down...?

The issue is caused by the Flame rods. Near the 2 pilots at the front and the back. Those small rods each that 'senses' the flame become inadequate, so they need to be replaced with a new pilot assembly from Rinnai that has longer rods and better coverage.

Contact your Rinnai dealer for details for replacement parts.
