WARRANTY COVeRAGe: HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered compo- nents manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period, HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty is subject to conditions, exclusions and limitations as described below. WARRANTY PeRIOd: Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent, authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for parts and labor for covered components is produced in the following table. The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These time periods reflect the minimum expected useful lives of the designated components under normal operating conditions.

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 of these facts we recommend using as few elbows as possible 4” Type “L” or and 30 feet or less of vent pipe. The maximum horizontal run “PL” Vent pipe should not exceed 18 feet.

  • Page 15: Main Wiring Harness

    Main Wiring Installation 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. This boiler should never be powered by the use of an extension cord. The recommended high and low voltages are, 130 VAC 60 Hz maximum high voltage, and 113 VAC 60 Hz minimum low voltage. The furnace will continue to operate at voltages as low as 105 VAC , although it can not be guaranteed that automatic ignition will occur. NOTe: If other sources of electrical power are to be used ( such as a generator ) for normal operation or emergency operation, this source should be checked before installation.

  • Page 21: Overheat Safety Zone

    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 remaining heat may cause the water temperature to continue to rise. If the temperature gets too high, the OVERHEAT SAFETY ZONE light on the control will illuminate, and the DARK BLUE circuit in the junction box is energized(see wiring diagram). This circuit will flow 120V to operate a circulator pump installed to flow to the overheat dump zone established in the original installation plan. If opening a zone valve is the chosen method of dumping the excess heat, a voltage reduction relay will most likely be needed. If the water temperature continues to rise to the risk of boiling point, the feed system will stop and the boiler will shut-down. A manual reset will then be required to operate the boiler. Without a dump zone in place, the excess temperature could build pressure to the point of opening the relief valve, or with the atmospheric conversion it may allow the water to boil and exit through the over-flow of the atmospheric tank. Both scenarios may create water damage and/or a slip hazard. The boiling temperature of water varies at different altitudes and atmospheric pressures. Therefore, at elevations above 3000 feet, and when using the atmospheric conversion, circuit board dipswitch #6 must be in the “ON” position.

This is usually a weekly maintenance procedure. Cleaning the burn pot with the scraper with a small amount of new fuel in the bottom is not a problem. First, scrape the ashes on the front of the burn pot into the ash pan. Then scrape the hole grid surface downward into the burn pot. When the stove is ignited these scrapings will be pushed out by the feeder. The illustration at left shows the hopper swing plate open for easy access to the burn pot. The burn pot can also be reached through the firebox door. NOTE: To minimize the amount of stress placed on the hopper swing plate hinges, opening of the hopper swing plate should be done with the least amount of fuel in the hopper as possible.

  • Page 37: Atmospheric Conversion

    Atmospheric Conversion Atmospheric Conversion: Item # 1-00-232200, provides automatic fill, and converts the heating system plumbing from pressurized to a zero pressure system. Allows for installation into more places where codes and standards restrict pressurized systems. Note that when using the atmospheric conversion, air bleeders and check valves may actually allow air into the lines. Another reason it is important to have a licensed Plumber involved in each phase of your installation. When using the atmospheric conversion, the circuit board dipswitch #6 must be in the “ON” position. This will lower the overheat temperature parameters to prevent boiling of the water. Since altitude affects the boiling point, it is also recommended to set #6 to “ON” at elevations above 3000 ft.
