Great questions. If you are looking at the front of the stove, the handle is installed on the right hand side of the stove. The installation manual is located here: https://hvacdirect.com/hvac/pdf/napoleon-S20i-Installation-Operation-Manual.pdf and page 35 includes a troubleshooting list. For more information on technical questions and concerns, we recommend that you reach out to the manufacturer, here at: https://www.napoleon.com/en/us/company/contact-us and they would be happy to assist you. Thank you and have a wonderful day.
