Venting venting Venting Use 4” pellet vent pipe only. 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. 4” Type “L” or Because of these facts we recommend using as few elbows “PL” Vent pipe as possible and 30 feet or less of vent pipe.

main Wiring Installation 14 To install power to the boiler, first remove the cover on the 4” X 4” junction box located on the back of the unit. There are several knockout holes provided for the incoming main power wires. Also, a knockout hole can be used for the auxiliary output overheat zone (if used). The minimum recommended circuit is 6 AMP - 120 VAC - 60 HZ. This boiler should be the only appliance on the circuit. If a 15 AMP circuit breaker is used at the distribution box, the boiler mus

Installing Duct Installation NOTE: Cold return water temperature (Sustained temperatures below 140 degrees Fahrenheit) will lead to condensation in the firebox. This moisture can lead to creosote formation. To help minimize moisture and creosote, it is strongly recommended that some form of temperature balance is incorporated into the return water system. NOTICE: When installing with the atmospheric conversion: All of the pressurized system components shown are not nec- essary. Air vents or bl

Over heat Safety Zone OverHeat Safety Zone (Dump Zone): STRONGLY RECOMMENDED in all installations. When the pellet boiler is operating at High burn, and all demand from the heating system stops, the control will reduce the feed rate and shut down completely as necessary. This may take several minutes, and the remain- ing heat may cause the water temperature to continue to rise. If the temperature gets too high, the OVERHEAT SAFETY ZONE light on the control (see page 23) will illuminate, and th
