Error codes
We haven't confirmed which error codes or diagnostic lights this model uses yet, so we're not listing any here rather than guess. Your owner's or installation manual (linked below) is the right place to check what a flashing light or code means on your unit.
Common problems
- The remote stops working. Put fresh batteries in the remote first. It's the most common, and the cheapest, fix.
- It won't light, or it lights and then goes out. Turn it off, wait a moment and try once more. If it still won't stay lit, stop there. Repeated tries won't fix it, and the cause usually needs hands-on diagnosis.
- You're not sure what a flashing light means. Look it up in the manual linked below before you try anything else.
When to call a tech
- Any gas smell (leave first, then call your gas supplier from outside)
- It won't light or stay lit after one retry
- The glass is cracked, or you notice unusual noises, soot or a strange smell when it runs
