To ensure optimal performance of your PortaSauna in the UK, it’s crucial to maintain proper ventilation and fire management. Keep the rectangular air intake vent at the bottom of the tent open, allowing fresh air to flow towards the stove. The air control vent on the ash tray should also be fully open. Start the fire with fire starter squares and 1-2 pieces of dry hardwood (optimally 30-40 cm long). After lighting, keep the stove door closed for about 15 minutes before adding more wood. Repeat this process to achieve the desired heat (around 82°C to 93°C). If necessary, adjust the ash tray position or add more wood to increase the temperature.
