After troubleshooting my problem with Craig, who was quite knowledgeable, helpful and exhibited patience with this newbie, I purchased the heater. I followed the very informative video for the install, but alas it wasn't working. Another call to Craig, and he guided my troubleshooting and discovered that I had one wire that wasn't in the right spot. Made the change and now all is good. Great experience.On 08/02/2024 by G. W.
