This optional kit will include all components necessary to install the exhaust blower on any external vertical wall surface. Choose a location for your stove that meets the requirements stated in this manual and allows installation with the least amount of interference to house framing, plumbing, wiring, etc.
Installation NOTE: Ensure that all vent connections are installed by placing three (3) screws evenly spaced and a small bead of high temperature silicone at each chimney connection. Also ensure that all vertical vent sections are properly supported and that all clearances to combustibles are maintained in accordance with the vent manufacturer’s specifications.
Installation THROUGH WALL VERTICAL INSTALLATION WITH EXHAUST BLOWER - FREESTANDING: Refer to INSTALLATION - INSTALLATION WITH EXTERIOR MOUNTED EXHAUST BLOWER - FREESTANDING and INSTALLATION OUTSIDE VERTICAL INSTALLATIONS - FREESTANDING. Ensure that vent pipe is properly secured to wall using wall straps. Maintain clearances to combustibles on vent pipe as well as unit.
Installation MASONRY FIREPLACE INSERT INSTALLATION - FIREPLACE INSERT: The Fireplace insert model requires a surround faceplate and a pedestal. When installing this unit, ensure that the pedestal is removed from the inside of the hopper and installed on the bottom of the unit (Refer to INSTALLATION - INSTALLATION OF PEDESTAL AND LEVELING LEGS - FIREPLACE INSERT).
Installation INSTALLATION AND REMOVAL OF CONTROL PANEL IN THE SURROUND PANEL - FIREPLACE INSERT: When installing the circuit board control panel into the surround panel, the surround does not need to be assembled. The circuit board will be found in the firebox. Place the circuit board control panel on the backside of the right surround panel so the hinge is on the outside and the top and bottom holes on the control panel line up with those on the surround.
Installation 6. Place the second side of the trim on the surround panel in the same manner used on the first side and secure in the same manner. 7. On the side trims, there are holes 2” (50 mm) from either end. Use a Phillips screwdriver to place a #8 screw 11⁄4” long in each hole and tighten (refer to Figure 36). This will keep the trim tight against the surround. Magnetic Strips Figure 33: Magnet placement on trim. 8.
Installation PLATED TRIM INSTALLATION: TO AVOID PERSONAL INJURY DO NOT REMOVE OR REPLACE TRIMS WHEN PELLET STOVE IS HOT! KIT COMPONENTS: Quantity Upper Cabinet Trim Description 2 Upper Cabinet Trim 2 Lower Cabinet Trim 1 Top Trim 3 Louver 4 #8 nut plated (spares) Lower Cabinet Trim TOOLS REQUIRED: ● T-20 screwdriver Left Cabinet Side #8 Hex Nut (x8) #8 Stud (x8) ●11/32” socket Figure 38: Right cab side with upper and lower cabinet trims.
Installation two (2) screws under the corner lips above the door. Align top then tighten screws. REMOVAL OF LOUVER BAR SET: Door must be open. The three (3) arrows in Figure 40 point to three (3) of the nuts that hold the louvers on. There are three nuts on each end. Remove the six nuts by hand; if the nuts are tight, a 11/32” socket can be used. When removing the louvers, pull one end of the louver up over the stud.
Installation THERMOSTAT INSTALLED: This control board can be placed into two (2) different modes: HI / LOW OPERATION: When the jumper J9 is not jumped then the control board is in a HI / LOW mode operation. If the unit has been placed in the HI / LOW mode, the unit will be taken to a low or idle setting when the thermostat is not calling for heat. When the thermostat calls for heat, the unit will go to the setting that is displayed on the control board Heat Indicator.
Installation HEAT LEVEL and when turned down to LOW HEAT LEVEL, a 0.07” to 0.11” w.c. (0.018 to 0.028 KPa). Some fuels may require higher or lower settings. The pressure readings are taken through a hole in the front of the firebox under the door, using a Magnehelic Gauge. Exhaust Blower Exhaust Channel Slider Damper Figure 43: Hole for Pressure test with Magnehelic Gauge. Note: Some parts have been removed in order to see components more clearly.
Troubleshooting DO NOT: ● Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard if handled improperly. Only qualified technicians should deal with possible internal electrical failures. ● Do not remove from the firebox any screws without penetrating oil lubrication. ● Hold the ON / OFF BUTTON down. This is a momentary contact switch and can be damaged if held down too long. WHAT TO DO IF: 1. The stove will not start. 2. The stove will not operate when hot. 3.
Troubleshooting hose from vacuum switch. Check exhaust vacuum readings by placing the open end of the vacuum hose on a Magnahelic Gauge (readings must be above 0.18” to 0.20” W.C. (44.8 to 49.8 Pa) on low fire). If the motor fails to reach a 0.10” W.C. readings, then replace the combustion blower. üPoor quality fuel – insufficient energy in the fuel to produce enough heat to keep the stove burning or operational. üExhaust temperature sensor failure.
Troubleshooting 6. The 200 °F ( 93 °C) high limit temperature sensor has tripped. üReset sensor and determine cause – was it convection blower failure or 160 °F ( 71 °C) temperature sensor failure? Bypass the 160 °F ( 71 °C) sensor, does the convection blower come on high? If no, replace the blower. If yes, replace sensor (located on the left side of the firewall). üCheck the fuses on the circuit board (see “TROUBLESHOOTING - FUSES”). 7. The convection blower will not function normally.
