    Installation design The first thing needed is deciding where and how the furnace will be installed. Things that need to be taken into consideration are Venting, Supply and Return Ducting, Electrical, and Condensation Drainage (if A/C is installed). Don’t forget access to the furnace for service. When the return air inlet position is known, the filter box and distribution blower can be installed.

    venting and Clearances Clearances to combustibles If installing the furnace in a room separated from the remaining living spaces, the minimum size of the room must be no smaller than 8’ x 8’. See Fig. 21. The reason for this is heat build-up and required space for service and normal operation.This is the minimum size of the room even if it is built of non-combustible material.

After the venting leaves the shaded area it may be installed as per the vent manufacturer instructions. (Only listed 4” pellet vent wall pass-throughs and fire stops may be used.) See Fig.

  • Page 15: Installation

    Installation Outside Air The use of outside air is optional. Connecting to outside air may be required by local codes, and is strongly recommended. To install outside air, use 2¾” I.D. metal flex pipe, part # 2-00-08544 (12’6”length) or part #2-00-08545 (25’ length). There is a break-away hole on the rear panel which must be removed before connecting the flex pipe.

There is a 100’ length of this cable supplied with the furnace. 100’ lengths of this cable can also be ordered separately, part #3-20-02583. Alternately, any Datacom cable -CAT3- 2 twisted pair 24ga solid wire can be acquired at a local electrical supply house.

    Operation Shut down Procedure: The proper way to shut down the furnace is to turn the mode selector to “OFF”. The control will decrease the feed rate to cool the fire. Once the ESP cools enough, the feeder will stop running. In order to ensure removal of smoke and gases from the remaining fuel in the burn pot, the combustion blower will operate until the ESP cools to a safe...

  • Page 29: Maintenance

    maintenance burnpot cleaning: The burnpot should be cleaned no less than once a week. For best operation the burnpot should be cleaned every time the hopper is filled with pellets. The fire does not have to be out to scrape the burnpot although it is recomended the furnace be on minimum burn at the time of cleaning.

  • Page 30: Ash Removal

    maintenance Ash removal It is recommended to remove the ashes when the furnace is not in operation. This lessens the chances of coming in contact with hot surfaces. Ashes can be removed while in operation but, extra care must be taken.
  • Page 31 maintenance Cleaning the accordion heat exchanger/firebox: This cleaning should be done monthly, or after each ton of pellets used. The frequency of this cleaning will be directly related to the quality and upper baffle the quantity of the pellets being used. Keep in mind that the cleaner the heat exchanger surface is kept, the higher the heat transfer efficiency will be.

See Fig. 69 Flip the latches up and pull the shield away from the furnace. It can not be fully removed, it can only be latch moved down over the wire until it hangs on the junction box.
