Hey can I ask you for some help? We purchased a new Suburban SW6DE heater and after installation, it runs for about 20 secs (gets hot) then shuts down. You have to go through about 30 minutes of resetting the on off button Before it will get hot enough to take a shower. Can you please advise me as to what I’m doing wrong? Heater was self installed. I followed some posts here for installation info but I believe it is installed correctly. Thanks for your time. You can call me if you like. 502-379-2889. Thanks for your help. This is my living quarters, not a summer home. Thanks.
