Solus fire pits  are certified as appliances just like a boiler or a stove.  There is a significant difference in the certification of a burner that is simply inserted into a vessel or sculpture.   Solus fire pits are tested by an independent laboratory and certified in their entirety.  There are many jurisdictions, municipalities and counties increasingly requiring full certification of the fire pit as an appliance.  Gas authorities and insurance companies who sign off on behalf of the installation are oftentimes the final inspection point who require this.  States like MA and CA and provinces like BC and ON have requirements for fully certified appliances in commercial applications. A fire pit must have a listing report to ensure compliance – see Solus certificates of conformity below
