Bolted or screwed together pieces Collar (smoke shelf / deflectors) may be removed, but must be able to be re-installed if the heater was removed.
6.3 installation into a combustible enclosure ! WARNING The stand-offs located on the back of the insert must not be removed when installing the insert into a built-in combustible enclosure. WARNING ! Outside air is mandatory for a combustible built-in enclosure install. When installing the insert as a "Built-in" heater, it is important to maintain the clearances to combustibles, see "MINIMUM CLEARANCE TO COMBUSTIBLES" section.

If installing 4" diameter vent vertically, it will be necessary to start with a 12" section of 3" diameter vent to clear the hopper, then increase to 4" diameter vent. A. To vent exit vertically, remove the two screws holding the exhaust cover. Figure 6.3.5 Exhaust Cover B.
7.0 insert finishing 7.1 Flashing installation ● 7.1.1 FIGURE 7.1.1 Secure the Right Flashing to the right side of the heater using two of the #8 x 1/2" screws. 3 4 1 5 HIGH 5 4 The three pieces of trim are assembled in the same manner as a picture frame. Place the corner brackets (with screw loosened) into the trim sections. Tighten the screw spreading the two pieces apart. Attach the adjoining section. Repeat with the opposite side. Tighten all screws firmly.
7.3 installing viewing door The main viewing door has been boxed separate from the heater, but MUST be installed before burning the heater. 7.3.1 ● Open both side panels, exposing the bushing on the left and the latches on the right. 7.3.2 ● Align the pins on the door to the bushing on the left side of the heater. Lower into place until both bushings touch. 7.3.3 ● Engage the latch hooks into the door frame. Snap the rear handle hook to lock the latch closed. FIGURE 7.3.2 8.
8.3 Lighting heater manually ! WARNING Heater may be hot. Other than placing a handful of pellets in the burn pot for lighting manually, never feed pellets through the glass viewing door. An "OVERFIRE" condition could occur, if more pellets enter the firebox than what the feed tube can deliver. Pellets must only be burned within the burn pot. Your heater can be lit manually without using the automatic igniter by following the procedure below. 8.4 ● 8.3.1 Press the ON / OFF button. ● 8.3.
AUTO / T-STAT / MANUAL This switch is used to select the operating mode. MANUAL: Sliding the switch down to manual will allow you to manually select the heat and blower settings. In manual mode the heater will run at your desired settings indefinitely, until you manually turn the heater off or the heater runs out of pellets. T-STAT: If you would like to have your heater operate using a thermostat, slide the switch to the middle position (T-STAT).
8.6 Installing a thermostat An optional millivolt thermostat is available to help keep the room temperature constant. NOTE: The thermostat must be installed by a qualified installer. ● 8.6.1 Disconnect the power supply. ● 8.6.2 Remove the right side panel to gain access to the rear of the control panel. ● 8.6.3 Strip and connect the thermostat wires to the green screw terminals on the back of the control panel. FIGURE 8.
9.0 General maintenance 9.1 Daily (whenever using the heater) 9.1.1 open main viewing door ! WARNING The front of the heater becomes very hot during operation. Let the heater cool completely before conducting service. A. Open the side doors on either side of the heater. B. On the right side of the heater are two latches. Release the latches by pulling the rear handle forward and disengaging the hook from the door frame. Swing open the viewing door. FIGURE 9.1.1a FIGURE 9.1.1b Side Door Latch 9.
9.1.6 cleaning the heat exchanger tubes ! WARNING The front edge of the hopper lid becomes very hot, do not touch the area below the handle. This rod becomes very hot during operation. Wait till heater has cooled completely or you must wear heat resistant gloves when cleaning or handling this heater. With the heater cool (or wearing heat resistant gloves), slide the heat exchange cleaner rod up and down several times to prevent the build up of ash on the heat exchange tubes.
9.2 Bi-weekly (or every 10 bags of pellets) 9.2.1 vacuum firebox ! WARNING The firebox becomes very hot during operation. Let the heater cool completely before conducting service. The more frequently you clean out the fly ash, the more efficient your heater will burn. A. Open the viewing door. See “OPEN MAIN VIEWING DOOR” section. LOUVRES B. Lift the burn pot out and set aside on a non-combustible surface.
9.3.2 soot and fly ash formation The products of combustion will contain small particles of fly ash. The fly ash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least once every year to determine if cleaning is necessary. 9.3.
9.3.6 check all seals Check for air leaks around the door, glass, and ash pan and replace gaskets as required. Air leaks into the firebox will decrease the heater's performance greatly, leading to excessive soot, inefficient burning, and may even cause a malfunction. Test the door seal by shutting the door on a piece of paper in various locations. If the paper can be easily slid out, air may be leaking around the door seal. Carefully inspect the door gasket and door catch.

13.0 frequently asked questions Before calling a service technician, read the following guide for answers to frequently asked questions. Q. When I first light the heater, pellets were not feeding and the heater turned off? A. When first starting this heater or when you completely empty the hopper of pellets, the auger feed screw is empty. If proof of fire has not been established the heater will turn off. Simply push the ON / OFF button again. Q.
14.0 troubleshooting ALL TROUBLE SHOOTING PROCEDURES SHOULD BE CARRIED OUT BY QUALIFIED TECHNICIANS OR INSTALLERS. CAUTION: When checking connections, installing jumper wires (for test purposes only) or replacing components, unplug heater from the receptacle to prevent electrical shock or damage to the components. NOTE: Many of the following tests will require that the side panels are removed from the heater or the insert be removed from its cavity to access the components.
SYMPTOM TEST SOLUTION HEATER SHUTS OFF AND THE #3 LIGHT FLASHES The hopper is out of pellets. - Refill the hopper. The hopper lid open. - Close the hopper lid. The burnpot is not seated completely into the burner housing. - Ensure the burn pot locating notch engages with the ignitor and that the burn pot sits flat. The burnpot holes are blocked. - Remove the burnpot and thoroughly clean it. The air inlet, the interior chambers, or exhaust system has a partial blockage.
SYMPTOM TEST SOLUTION SMOKE SMELL COMING BACK INTO THE HOME There is a leak in the vent pipe system. - Inspect all vent pipe connections. Make sure they are sealed with RTV silicone that has a temperature rating of 500°F or higher. Also, seal joints with UL-181-AP foil tape. Also, make sure the square to round adapter piece on the combustion blower has been properly sealed with the same RTV. The gasket on the combustion blower has deteriorated.
SYMPTOM TEST SOLUTION Circuit board malfunction. - Time the fuel feed light at each setting (after the heater has completed the start-up cycle). If the auger motor runs constantly, the board is defective. Bad pellets (applies to GLASS SOOT’S UP AT A VERY FAST RATE only). - The brand of pellets or the batch of pellets that are being used may be of poor quality. If possible, try a different brand of pellets. You might also want to try a brand that is made from a different type of wood (softwood vs.
