1.0 Installation of your Morsø stove Installation of woodburning stoves must be safe and legal. If your Morsø stove is not installed correctly, it may cause a house fire. To reduce the risk of fire, the installation instructions must be followed carefully. Contact the local building officials about restrictions and installation inspection in your area.
1.2 The chimney / flue system Note that the flue system must be independently secured and must not rely on the stove for support. The stove must not be connected to a chimney flue serving any other appliance. (Several flues may run up a single chimney stack; use one flueway per appliance). Use a residential type masonry or listed type HT factory-built chimney.
1.3 Flue Connection The stove is supplied from the factory with a flue collar fitted to the top plate and a round blanking plate blocking off the rear flue exit (behind the rear shield plate). Use a 24 MSG black or blue chimney connector or listed double wall chimney connector. Refer to local codes and the chimney manufacturer’s instructions for precautions required for passing a chimney through a combustible wall or ceiling.
When the stove is positioned near non-combustible materials, a gap of 4 inches or more is recommended for cleaning purposes and to ensure that heat circulates around the stove and out into the room. 3410 and 3450 CLEARANCE REQUIREMENTS STANDARD RESIDENTIAL INSTALLATION...
