The model you choose must be approved for use in a mobile home. Proper venting is an essential for proper appliance performance, dwelling safety, maintenance frequency, and indoor environment. Pellet stoves produce little or no visible smoke after startup, but exhaust gases, fine ash, and water vapor must be removed safely from the appliance to the outdoors without leaking into the house. The purpose of all vents is removal of combustion by-products during normal operation. A few stoves operate without a combustion air fan and use natural draft both for exhaust and combustion air intake.
Some heat also moves through the vent.
Protection of nearby combustibles is essential. The minimum clearance between the vent and combustibles, as specified in the vent installation instructions, must be met or exceeded to assure safety. The product specifically tested and listed for use with pellet stoves is PL vent pipe, labeled as tested to UL 641. Pipe joints must be sealed gas tight to prevent exhaust products moving through the vent under pressure from leaking into the home. Stoves tested and listed requiring PL vent must use no substitute venting materials.
