New heater trips breaker after couple hours

[KYBluegrass]

New Raypak 266A Nat gas heater installed May 2023.

Dedicated GFCI 2-pole 20-amp breaker.

Runs for an hour or 2 and then trips. I reset and run again for over an hour and trips.

Electrician came back to check and shrugged.

I assume I just need to get Raypack tech over, but wondering if anyone’s ever had this issue. Feel like this is out of my DIY skills…

No error codes.

The breaker could be bad. I would think a competent electrician could track down the problem. I don't like integrated GFCI breakers.

How much current is the heater actually pulling? Do you have a Kill-a-Watt or similar device?

I don’t, but willing to get one.

Edit to add: It’s had this issue since install. Have barely used it.

These don't work for direct wired 220 volt appliances.

Going for 2 hours and then quitting makes me think it's the GFI portion of the breaker. Could be the blower motor has dirty power.

Look into getting a Pentair GFCI breaker. Check this post: GFCI breaker started tripping

KY,

Your heater should only draw a couple of amps, so you must have a GFCI issue.

I don't believe that gas heaters even need a GFCI breaker, but don't know that for sure.

I would install a standard breaker and see if the unit runs ok, even if just for a test.

Thanks,
