Venting Venting Venting Use 4” pellet vent pipe to vent your PB105. A combustion blower is used to extract the combustion gases from the firebox. This creates a negative pressure in the firebox and a positive pressure in the venting system as shown in Fig. 4. The longer the vent pipe and more elbows used in the system, the greater the flow resistance. Because 4” Type “L” or of these facts we recommend using as few elbows as pos- “PL” Vent pipe sible and 30 feet or less of vent pipe. The maximum

The benefit of outside air is higher efficiency and reduced venting restrictions mainly noticed in small and very tight houses. To install outside air, use 2 3/4”" I.D.galvinized steel flex pipe, part # 2-00-08544 ( 12’ 6” length) or part # 2-00-08545 ( 25’ length) See Fig. 6. There is a break- away hole on the rear panel which must be removed Inlet Cover part# before connecting the flex pipe
