Also the joints must be sealed with high temperature silicone We cannot emphasize enough the importance of sealing every seam and joint in the venting system which is inside the home Even the smallest pin hole can leak and when it does you will smell wood smoke or a creosote smell in the room If this occurs check for leaks Leaks are easiest to see during start up Alternatively you can use a smoke pellet to leak test the venting before lighting your first fire XXV Pellet Stove 7 Outside air flex pipe goes here Flex pipe partt 1 00 08543 Inlet Cover partt 1 10 08542 Indoor Half Adjustable from 4 1 2 to 10 5 8 wall 8 XXV Pellet Stove Outside Air Here are four benefits of outside air 1 Having air introduced from outside the living area boosts overall efficiency 2 It eliminates draft problems that can occur in tight homes 3 It reduces smoke spillage in the event of a power failure 4 It allows your vent termination to be as close as 18 from windows or doors Outside air is optional except in mobile homes and where building codes require The benefit of outside air is mainly noticed in small very tight houses To install outside air use 2 3 8 1 0 non combustible flex pipe There is a break away hole on the rear panel of the XXV stove which must be removed before connecting the flex pipe The pipe should be run outside and terminate to the side or below the vent pipe outlet so th
6. of these facts we recommend using as few elbows as possible and 15 feet or less of vent pipe The maximum horizontal run should not exceed 48 If more than 15 feet of pipe is needed the interior di ameter should be increased from 3 to 4 because a larger pipe causes less flow resistance Be sure to use approved pellet vent pipe wall and ceiling pass through fittings to go through combustible walls and ceilings The use of a starting collar is not always necessary The first piece of pipe should be fastened securely with at least 2 fasteners to the flue collar of the stove If a starting collar is used to attach the venting system to the stove the starting collar must be sealed to the stove with high temp silicone caulking Vent Pipe Pellet venting pipe also known as PL vent is constructed of two layers with air space between the layers This air space acts as an insulator and reduces the outside surface temperature to allow a clearance to combustibles of only 3 inches The sec tions of pipe lock together to form an air tight seal in most cases However in some cases a perfect seal is not achieved For this reason and the fact that the XXV operates with a positive vent pressure we specify that the joints also be sealed with silicone Aluminum tape can also be used for any joint that is 1 ft or more from the outlet of the stove When using the top vent option 6 inch single wall pipe must be connected with at least three 3 screws
