We purchased a Ravelli RV100 in August 2022 and we have had nothing but issues with it, is it possible we received a lemon? First, the tech never set up our RDS so we had to have a service call from another company we purchased from. We got the No Flow alarm when turning on the stove and when I finally get the stove up and running I try and go to the setting to adjust % of pellets and % of air draft. It goes to a blank screen and cannot turn it off unless I turn off in the back. What are we doing wrong? This should not be happening with a stove less than a year old and costing over 7k dollars.
