Venting

A combustion blower is used to extract the com- bustion gases from the firebox. This causes a nega- tive pressure in the firebox and a positive pressure in the venting system as shown in Fig. 7. The longer the vent pipe and more elbows used in the system, the greater the flow resistance. Because of these facts we recommend using as few elbows as pos- sible 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 diameter should be increased from 3" to 4" because a larger pipe causes less flow resistance. Be sure to use ap- proved pellet vent pipe wall and ceiling pass- through fittings to go through combustible walls and ceilings. The use of a starting collar is not al- ways 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 sections 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 P68 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.

W e 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.
