The direct vent design ensures none of the traditional moisture build up associated with propane heating and allows the heater to use outside air for combustion instead of interior air to keep oxygen levels steady with no worry of oxygen depletion. Despite its low output, the P9000 will consistantly put out a good amount of dry heat to keep your small space warm and toasty. The P9000 propane heater comes with one 28” length of flexible chimney to allow you to accomplish installations in tight spaces. The maximum length of the chimney is 56”. Also while we recommend a straigh installation if possible, the flexible venting allows for a horizontal exit. Included as well is a cap that doubles as a through deck fitting. The cap comes complete with a thick rubber gasket for a water tight seal and a stainless steel dress ring for the interior of your boat
