We have an All Nighter Mid Moe in our house, and have used it as a primary heat source for the last 15 years. It's a great stove. We are moving and are considering renting our house - but if we did, we would not want the tenants to use the stove due to possible liability issues. We also do not want to remove/get rid of the stove. Does anyone know if there is a way to seal the stove off so that it is not usable, but could be unsealed/used again in the future?
