Fig. 1 Fig. 2 1. Fines are small pieces of broken pellets (sawdust). Fines do not flow easily and often build up on the hopper funnel bottom angles. These fines can be pushed into the feeder opening and then fill the hopper with pellets. As the system works, they will be burned.
Automatic Ignition/Operation The Accentra Insert is more than just automatic ignition, it is also automatic temperature control. The automatic system will allow the fire size to be adjusted to match the heating needs and even put the fire out if necessary. If heat is needed after the fire is out, the Accentra Insert will automatically re-ignite and adjust the fire size to match the heating need.
Fig. 5 Fig. 7 1. Fines are small pieces of broken pellets (sawdust). Fines do not flow easily and often build up on the hopper funnel bottom angles. These fines can be pushed into the feeder opening and then fill the hopper with pellets. As the system works, they will be burned.
The Accentra Insert is capable of manual operation. This also allows the operator to manually control operation during an emergency (i.e. igniter failure, when using a 502H battery backup, or when using certain generators.) The unit can be switched between "AUTO" and "MANUAL" at any time during operation. Fig.
Power Light Indicates power to the control. Status Light Will be lit in either stove or room temp mode when pointer is not within off position band except after normal shut down. Blinks to indicate errors listed below. Indicates power to distribution blower.
Installation: Removing unit from skid How to Reduce the Weight for Installation 1. Remove the top/lid assembly and side panels. • Note: Removal of the cast hopper lid itself is NOT necessary or recommended. • Note: The hopper lid must be in the "OPEN" position before the top/lid assembly can be lifted of f or reinstalled on the stove body.

Beginning Installation IMPORTAN T: The mounting f rame/s ur round assembly and flue piping is the most critical part of the installation and must be done correctly and installed securely. 1. Choose the chimney configuration that is best suited for the installation. See venting section. •...
Optional Wing Extensions Optional wing extensions are made for fireplace open- ings which are larger than the cast wing. The 3 piece wing extension is 48" wide by 34"high. Custom oversized wing extensions can be purchased from Harman for any fireplace openings larger than the standard wing extension area.
7. If the room sensor is used as a return air sensor rather than a room thermostat/sensor, the black cable will not be used. The room sensor itself (gray cable with black and red wires) will be connected to the blue twisted wires from the control board.
9. Install the completed frame/surround assembly into the firebox and level/plumb the wing to the fireplace face using the leveling bolts as jacks. * Ash protection must be used from hearth opening to 6" in front of door glass and 6" to each side of the stove body to protect any combustibles from hot ashes.
15. Install the cast side panels by sliding them down over the lasered hinge pin. Note: Check for rotational swing, but finish with them in the open position. The cast side panels may need adjustment after the stove body is latched into place and the front door is closed. Fig.
Connecting the Room Sensor Connecting the room sensor to the blue twisted wires from the control board: • (2) 3/16 inch male terminals are provided for the ends of the room sensor wires. • They will mate with the female terminals on the blue twisted wires.
22. Slide the stove body into the mounting frame. • Note: The two spring latches on the bottom right and left side of the body must be in the proper position to enter the latch holes. (See fig. 37). • Latch the (2) spring latches into place. 23.
Wiring Always disconnect the power cord before the unit is pulled from the mounting frame. As you can see, the control board is easily accessible from the rear with the body pulled out of the frame, even if it is only pulled out several inches. •...
Low Draft Voltage Adjustment After the installation is completed but before the first fire is lit, check and record the high and low draft readings. Fig.44 These units are pre-tested at the factory with exactly 120 Volts A.C., 60 Hz. They are checked and adjusted for firebox tightness, gasket leakage, motor operation and igniter operation.
Mobile Home Installation Mobile Home Installation Mobile home installation should be done in accordance with the Manufactured Home and Safety Standard (HUD), CFR 3280, Part 24. When installing the Accentra in a mobile home several requirements must be followed: 1. The unit must be bolted to the floor. This can be done with 1/4"...
In flue pipe In fan chamber & starter collar Fig.46 + = Positive static pressure = Negative static pressure Venting A combustion blower is used to extract the com- bustion gases from the firebox. This causes a negative pressure in the firebox and a positive pressure in the venting system as shown in fig.
Vent Pipe Be sure to use approved pellet vent pipe wall and ceiling pass- through fittings to go through combustible walls and ceilings. Be sure to use a starting collar to attach the venting sys- tem to the stove. The starting collar must be sealed to the vent pipe with high temp silicone caulking.
Venting The chimney top must be capped to prevent rain and/or snow from entering the chimney. See Page 21. for information on the optional Harman Adjustable Stainless Steel Intake Extension. Fiberglass insulation pac ked a bove the damper opening and sealed plate.

Requirements for Terminating the Venting WARNING: Venting terminals must not be re- cessed into a wall or siding. NOTE: Only PL vent pipe wall pass-throughs and fire stops should be used when venting through combustible materials. NOTE: Always take into consideration the ef- fect the prevailing wind direction or other wind cur- rents will cause with flyash and /or smoke when plac- ing the termination.
Maintenance - Cleaning Glass on View Door The unit should be out and cool to clean the door glass. It may not always be possible to allow the unit to cool off before cleaning. Therefore, if the unit is turned to the lowest setting about 1 hour before cleaning, it will make it possible to clean the glass with the unit in operation.
