Process inside your stove, it is extremely important that theĮxhaust system be properly installed and maintained.ĭoors must remain closed while in operations and the seals on the Is then pulled across the heat exchanger by the exhaust motor orĪs the stove reaches operating temperature, roomĪir is then circulated around the heat exchanger by a room airīlower, distributing warm air into the room.īecause a forced draft pressure is required for the combustion Should ignite the fuel within 3-5 minutes of pressing the On/OffĪs pellets fill the burnpot and ignite, outside air is drawnĪcross the fuel and heated during the combustion process which Your stove is equipped with an automatic ignition system that Pellet Stove Exhaust Fan - Draft Fanįor example here is an excerpt from the Serenity Pellet stove produced by Castle: Setting a higher voltage causes the fan to run faster, extracting more heat from the pellet stove. The user can set the exhaust voltage, called "Stall voltage" at an of five settings between about 85V and 110V that in turn regulate the stove's blower. Pellet Stove Exhaust Voltage Adjustmentįrom our same example pellet stove, the Serenity model, the manufacturer explains another control over pellet exhaust draft, the exhaust fan voltage.Įxcerpt: Increasing the exhaust voltage, and thereby increasing theĪmount of air in the burn pot, will also assist in burning lowerquality fuels that may otherwise cause unwanted buildup. (Water Column) and normal pellet stove "low draft) of -0.35 to -0.45 in. Harman specifies a normal pellet stove "high" draft (for their model) of -0.50 to -0.60 inches of W.C. Other pellet stove installation manuals, for example the Harman Pellet Stove cited below, specifically describe using a manometer to check the appliance draft and may provide a mechanical adjustment of the combustion motor speed. Travis Industries recommends a minimum vertical vent of 5’ to ensure adequate draft Illlustration: The AGP Pellet Stove from Lopi, Travis Industries, excerpted from the company's instruction manual cited below. Exhaust draft fan voltage adjusts fan speed. Using Castle Pellet Stove's Serenity Pellet Stove as an example, here we illustrate examples of controls on pellet stove heaters, all of which ultimately affect the stove's exhaust draft. Pellet stoves usually make use of a draft fan for proper burning, though in event of a power failure some models permit limited operation using natural draft.Ī separate blower fan helps extract heat from the pellet stove and transfer it to room air. Pellet Stove Draft Measurement, Settings, Controls We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article series catalogs and describes all types of air and draft regulation devices used in buildings where control of heating appliances is needed. Here we describe various methods used to control the draft and airflow through wood-pellet burning stoves or heaters. Pellet stoves usually operate using a forced draft that supplies combustion air and effects the exhaust of combustion products, but to readers unfamiliar with these devices it can come as a surprise that a typical pellet stove heater has at least two and some more than two adjustments to the stove's draft and to its heat output.
