Abnormal Flame Pattern - Rinnai Novo Operation Manual

Abnormal flame pattern

Each Rinnai flame fire has a distinct flame pattern, refer images below. This should look the same
every time you start your fire, after an initial warm up period of approximately 20 minutes.
Abnormal flame performance and/or pattern can indicate a problem with your fire, such as blocked
gas injectors, or shifting of burn media. There are some warning signs that could indicate a
problem:
- Unusual smell from the appliance
- Continued difficulty or delay in establishing a flame
- Either very short or very long flames
- Flame only burns part way across the burner
- Severe soot building up on the inside of the glass
If any of the above signs occur, please contact Rinnai.
