To install the Enviro Westport Cast Iron stove:

1. Cut Openings: Cut a 10-inch (25.4 cm) hole in the ceiling and roof for the flue outlet.
2. Ceiling Support & Insulation Guard: Install the ceiling support and insulation guard.
3. Roof Flashing: Install the roof flashing under the roofing material to create a watertight seal.
4. Flue Pipe Installation: Install the flue pipe from the top of the stove through the roof, ensuring all clearances to combustibles are maintained.
5. Corner Installation (Optional): If installing in a corner with a 90° elbow in the horizontal plane, subtract 36 inches (91.4 cm) from the allowable horizontal run.
6. Drafthood Adaptor (For Vertical Venting): If using a vertical vent, install the Drafthood Adaptor (50-841) and wire it to the gas control valve.
