• Remove ashes from the ash pan and replace with a moisture absorbing material (such as kitty litter) to keep the interior of the stove dry. • Inspect and clean the refractory package and catalyst. • Clean the dust from the inner sides of bottom, rear or pipe heat shields if your stove is equipped with them. Clean surfaces are better heat reflectors than dirty surfaces. • Touch up the black paint. 24 7001135 Dutchwest The Chimney Connector When to Suspect A Combustor Problem TWO WEEKS: • Inspect the chimney connector and chimney. Clean if necessary. TWO MONTHS: • Inspect the chimney and chimney connector. Pay particular attention to the horizontal runs of chimney connector, and the elbows. Clean the system if necessary. Yearly Spring Cleaning • Disassemble the chimney connector and take it outdoors for inspection and cleaning. Replace weak sections of connector. • Inspect the chimney for signs of deterioration. Repairs to a masonry chimney should be made by a professional mason. Replace damaged sections of prefabricated chimney. Your local Dutchwest dealer or a chimney sweep can help determine when replacement is necessary. • Thoroughly clean the chimney. Care of the Catalytic Combustor This wood heater contains a catalytic combustor, which needs regular inspection and periodic replacement for proper operation. It is against the law in the United States to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if the catalytic element is deactivated or removed. Under normal operating conditions, the catalytic combustor should remain active for two to six years (depending on the amount of wood burned). However, it is important to monitor the combustor periodically to ensure that it is functioning properly, as well as to determine when it needs to be replaced. A non-functioning combustor will result in a loss of heating efficiency, and an increase in creosote and emissions. The combustor should be visually inspected “in place” for fly ash accumulation and physical damage three times per year. Actual removal of the combustor is not recommended unless a more detailed inspection is warranted because of diminished performance as outlined below. The refractory package housing the catalytic combustor should be inspected annually for a build-up of fly ash and cleaned if necessary. This may be done during examination of the catalytic combustor. There are two ways to evaluate the performance of your stove’s combustor. The first is to monitor the temperatures on the probe thermometer. A properly-functioning combustor should operate in the range of 800-12000F. (430-650°C.). Combustor temperatures consistently less than 8000F. (430°C.) merit a closer examination of the combustor. The second performance test is to observe the amount of smoke leaving the chimney — both when the combustor has achieved “light-off” and when it has not. Follow this simple two-step procedure: • With a fire in the stove and the combustor properly activated by the closing of the stove damper to route smoke through it as described in the Operation Section, go outside and observe the smoke leaving the chimney. • Then, open the stove damper and once again observe the smoke leaving the chimney. Significantly more smoke should be observed after the second step when the stove damper is open and exhaust is not routed through the combustor. Be careful not to confuse smoke with steam from wet wood. Unlike smoke, steam disappears very quickly in air. If either of these tests indicates a problem, consider other possible factors as well. Assess Your Present Operating Conditions In Spring or Fall, draft strength is less than in the middle of winter, and a related change in stove performance may result. Small hot fires are a good solution to sluggish performance under these conditions. Burning “green” (insufficiently seasoned) wood will result in poorer performance than when burning properly seasoned fuel. Was your fuel supply good and dry to start with, or has it changed? You may have to run your stove hotter (more air) to achieve good performance if you are burning green or wet wood. Also, any changes in operating routine should be considered at this time as a possible reason for changed performance. Once you have ruled out any other possible causes for a decline in performance, you may proceed with an inspection of the catalyst. 7001135 25 Dutchwest Remove and Inspect the Combustor • Wear safety glasses, a dust mask, and gloves. • Remove the four bolts that secure the stove top plate. There are two each on both the left and the right side, just under the top plate overhang. With the bolts removed, lift the top. Remove these bolts ST443 Fig. 31 Remove four bolts securing stove top plate. The combustor is located beneath the removable re- fractory package. • Carefully remove the refractory package. It is ex- tremely delicate; handle it as little as possible. Stove Top Catalytic Burner ST444 Fig. 32 Remove refractory p...
