Safety and Environmental Testing The H530 Insert/Firebox for the Klassic has been tested by OMNI-Test Laboratories, Inc. of Portland, Oregon and is listed to UL 1482 and ULC S628. It is also EPA certified. Features and Items Included Your KLASSIC has a built-in convection system, so it creates air circulation in the room to spread the heat faster and more evenly.
Specifications UL 1777 Listed chimney liner (with a 6” (15cm) diameter) up through the block off plate of an existing masonry chimney, a zero-clearance chimney, or Class A, UL-103 HT, 6” (15cm) diameter chimney Dimensions (h x w x d) – 60” x 32” x 22” (152cm x 81cm x 56cm) Firebox Dimensions (h x w x d) – 14” x 24” x 12” (35cm x 60cm x 30cm) Thermal Output – 20,000 BTU (6 kW); range is 11,100-28,800 BTU Approximate heating area – 600-1,500ft2 Minimum stove pressure at above output – 15 Pascals Efficiency –
Chimney The Klassic must be installed using a Class A UL 103 HT approved factory-built chimney system or a code-approved masonry chimney with a flue liner. In Canada, the installation must conform to NFPA 211 or CAN/CSA-B365. The chimney must extend through the roof at least 3’ (1 m), and 2’ (6 m) above any structure within 10’ (3 m). The condition of the chimney and height is very important. We recommend a minimum height of 10’ (3 m) above the stove collar.
This prevents any amount of condensed or liquid creosote from running down the outside of the pipe or the stove top. All joints, including the flue collar connection must be secured with three sheet metal screws to ensure that the sections do not separate. For the best performance the chimney connector should be as short and direct as possible, with no more than two 90° elbows. The maximum horizontal run is 36" and a recommended total length of single wall stove pipe connector should not exceed 10 feet.

Before installation, it is also important to check that the Vermiculite panels are correctly fitted in the combustion chamber. The wood holder in the combustion chamber is not to be removed. On some baffle plates you will find a metal band. This band is mounted for transport protection only, and should be removed. Heat generation and distribution The Klassic is really two stoves in one. Inside is the actual stove, produced from strong steel plates, and on the outside a covering of steel.
3. SENSIBLE WOOD BURNING Proper wood burning When dry wood is burned in a wood-burning stove the following process occurs (over a period of approx. 1 hour): - After lighting the log starts to dry and heats up. - After drying the temperature of wood rises to approx. 300–400°F (150-200°C) and is converted into combustible gases/charcoal. - As the wood is gasified a certain portion of the gases produced burn and are converted into carbon dioxide and water.
Types of fuel and heating values Combustion involves conversion of the fuel from solid form into gases, water vapor and charcoal. The heating value is an expression of the content of combustible gases - stated in kcal/kg. All wood has roughly the same heating value per kilogram. The lighter the wood, the more that must be used to achieve the same heating value as with a heavier species of wood. Type of wood Beech and oak Ash Maple Birch Mountain pine Fir Poplar Dry wood - Lbs./ft3 (Kg/m3) 36.2 (580) 35.
4. OPERATING INSTRUCTIONS First Fire Once your Klassic stove is installed and all instructions have been read, the first fire can be started. However, please take careful note of the following: - Your new stove should be broken in gently for top performance and to prevent paint damage, cracks in the vermiculite or firebox lining, and excessive wear and tear. - The baffle plate and vermiculite panels may crack under hard impact. These are not covered by the warranty, so avoid tossing the wood in the firebox.
5. TROUBLESHOOTING Combustion problems can arise if the combustion conditions are not optimal. This can be corrected by following the advice given below. Lighting and burning problems are usually due to wet wood or insufficient draft.
6. MAINTENANCE Gaskets and vermiculite panels are parts which need to be replaced from time to time – depending on how much you use your stove. In some cases, you may need to replace them every year, while in others, replacement every second or third year will suffice. As a rule of thumb, gaskets need to be replaced when it has become flattened and the door no longer fits tightly against the front of the stove. You can purchase gaskets – with adhesive – from your local dealer.
7. WARRANTY The Klassic comes with a 5-year warranty. The warranty covers defects in materials or workmanship. Any claims during the warranty period should be directed to the dealer who sold the stove. All stoves from Wittus come with their own individual serial number on the type plate on the top of the firebox. Record this number and keep it in a safe place. Provide the stove model and serial number to your dealer in connection with service tasks.
