- Construct brick support walls for the unit to your personal desired height. Concrete lintels can be used for the base support.
- Position the unit and cover the back, sides and top with insulation, before unit is bricked in. Any type of fire-glass wool or ceiling insulation can be used. Not included with this product.
- To allow for expansion, ensure a gap of 20mm between back and sides of the body of the unit and the brickwork.
- It is recommended that one steel flue pipe be installed. The remainder of the chimney may be constructed from brickwork. You may choose to use more than one flue pipe.
- The inner dimensions of the chimney must not be less than the flue outlet opening on the top of the unit. Example 230mm X 400mm. The height of the chimney is very important to ensure the correct draw of smoke. The height of the opening of the chimney should be at least 0.5m above the apex of the roof. If the horizontal distance between the chimney opening and the roof apex is more than 3m, the vertical height may be made less. Please note that wind conditions in certain areas may affect the draw of the chimney and the vertical height may need to be extended.
- Steel flue linings will provide a smooth surface for better draw and protect the brickwork against heat corrosion.
- Use standard flashing material and procedure to waterproof the roof around the chimney. Not supplied with this product.
- The flue can be offset to avoid obstructions, providing sufficient support to prevent sagging. 45 Degree bends are available at Megamaster Retailers.
- A rotating cowl is necessary to prevent down drafts on windy days and will prevent rain from entering the chimney. The chimney and the cowl must be 100 % level and the gap between the lowest part of the cowl and the chimney must be minimal. A “bolt-on base” can be purchased for the unit. (Not included with fireplaces).
- After installation, all exposed parts of the chimney and rotating cowl can be painted with good quality heat resistant black enamel paint.
- The rotating cowl axle must be greased regularly to avoid rust. The cowl is supplied with 2 x stainless steel ball bearing to allow the cowl to rotate freely. Slide these two bearing into the hollow round tube of the base.
- Before having your first fire, a normal size fire is to be made and burned until no paint smell remains. Open all doors and windows to allow the smell to vent properly.
