Whenever a furnace, direct-fired water heater, or boiler is installed, the total installation must be brought into compliance with the requirements of NFPA 211 and all other rules adopted by the Board BEFORE the furnace, direct-fired water heater, or boiler is fired. Prior to leaving the installation (whether installed inside or outside any structure) unattended, the licensed solid fuel technician must observe, inspect, and test the equipment to ensure that the installation is operating safely in accordance with the Board's rules.
