  • Page 33: Operation Instructions

    OPERATION INSTRUCTIONS 5.1 Fuel The Astra 38 is designed to burn natural wood only. Higher efficiencies and lower emissions generally result when burning air dried seasoned hardwoods (moisture content below 20%), as compared to softwoods or to green or freshly cut hardwoods. The following are a few signs indicating that firewood is sufficiently dry for use: (a) cracks on the ends and surface of the logs, (b) lighter in weight, and (c) color (yellow/grey).

  • Page 34: Starting A High Efficiency Fire

    The left combustion control lever is the Activator. When starting a fire or adding a new load of wood, the Activator must be pushed in to allow maximum air to enter the firebox. The right combustion control lever is the Burn Rate Selector.

  • Page 35: Adding A New Load Of Wood

    NOTE: Sufficient air exchange is necessary for the fireplace to operate properly. Air is required in order to maintain the combustion of the fireplace. If the house is airtight, the fireplace may not function properly. If the fireplace is deprived of air, it will be necessary to provide a source of fresh air into the dwelling. This may be done by using an air exchanger unit or simply by opening a window or a door near the fireplace partially for a few minutes.

  • Page 36: Troubleshooting

    TROUBLESHOOTING 6.1 Backdraft / Smoking Draft is the force created by a difference in pressure, which moves air from the appliance up through the chimney. It is important to operate the Astra 38 with proper draft to ensure optimal performance of the unit. Draft is depended on the length of the chimney, local geography, nearby obstructions and other factors.
