7 Design: The rst thing that needs to be done is deciding where and how the boiler will be installed. Things that need to be taken into consideration are the intended use of the boiler for example, is the boiler going to be used as your primary heating system or is it going to be used as a secondary or backup heating system.
8 NOTE: All installation clearances and restrictions must be adhered to. INST ALLA TION IS T O BE PERFORMED BY A QUALIFIED INST ALLER. NOTE:Use only 4” diameter type “L” or “PL” venting system. Be sure to inspect and clean exhaust venting system frequently .
9 Requirements for T erminating the V enting W ARNING: V enting termi nals must not be recesse d into a wall or siding. NOTE: Only PL vent pipe wall pass-throughs and re stops should be used when venting through combustible materials.
10 Fig. 3 A voiding Smoke and Odors - Negative Pressure, Shut-down and Electrical Power Failure. T o reduce the probability of back-drafting or burn back in the pellet boiler during a power failur e, it must be able to draft naturally without exhaust blower operation.
1 1 The minimum vent conguration is a 90 o or T ee on a starter collar and a 24” length horizontal through an exterior wall. A cap on the end should direct the ue gasses down and away from the structure. See Fig. 5. The maximum horizontal length is 18 feet.
12 Chimneys taller than 20’ above the connection will require a draft test to determine if the draft is too high. Note: The high burn draft should not exceed .85 IWC. Some form of a restrictor plate may be required at the top of high chimneys to reduce the draft.
13 Outside Air T o install outside air , use 2 3/4” I.D.galvanized steel ex pipe, part # 2-00-08 544 ( 12’ 6” length ) or part # 2-00-08545 ( 25’ length) See Fig. 6. There is a break- away hole on the rear panel which must be removed before connecting the ex pipe.
14 T o install power to the boiler , rst 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.
15 Installing Duct Cold return water temperature (Sustained temperatures below 140 degrees Fahrenheit) will lead to condensation in the rebox.
16 Installing Duct/Air Conditioning Boilers intended to be connected to an existing boiler or boiler system shall: 1. Be capable of being installed without interfering with the normal delivery of heated water from the original boiler to the radiation system.
17 NOTE: ALW A YS REFER T O THE INDIVIDU AL C OMPONENTS RECOMMENDED INST ALLA TION INSTRUCTIONS FOR THE PROPER MOUNTING POSITION AND LOCA TION WITHIN THE PIPING SYSTEM.

20 20 OverHeat Safety Zone (Dump Zone): STRONGL Y 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 .
21 Draft T est Procedur e After the venting is completed, the rebox low draft will need to be checked and possibly adjusted. After removing the 3/8” bolt from the draft hole shown in Fig. 9, insert the draft meter tube.
22 Fuel and Fuel Storage Pellet fuel quality can uctuate from manufacturer to manufacturer , and even from bag to bag. Hearth & Home T echnologies recommends using only fuel that is certied by the Pellet Fuels Institute (PFI).
23 Power Light Indicates power to the contr ol boar d. Status Light W ill be lit anytime ther e is a call for heat. Combustion Blower Light Indicates Power to combustion blower Feed Moto r Light Indic ates Power to the feed motor . Max T emp dial The “Max T emp Dial” is used to set the desired maximum operating temperatur e of the boiler .
24 Setting The Boiler T emperature Without the Outdoor Air T emperature Sensor Installed T o set the maximum boiler water temperature, sim- ply turn the Max. T emp. water temperature dial to the desired setting. The control and the boiler will then perform to achieve and maintain the set temperature.
25 Pellet Boiler Outdoor Air Reset Operation When the outdoor sensor is installed, at 20° F . or below OA T (Outdoor Air T emperature), the boiler will operate at the temperature set on the Maximum T emperature knob.
26 1. T urn Mode Selector to “OFF”. This resets the control in addition to turning it off. Starting A Fire Automatically 2.
27 4. If Starting After an Empty Hopper , T urn Feed Adjuster to “TEST” (for one 60 second cycle). This will feed pellets into the auger tube and also allow you to check the motors for operatio n. NOTE: The auger motor will not operate with any of the doors open.
28 8. T urn the MIN. TEMP . Dial on the control board to the desired Minimum temperature. This will start the lighting process if the temperature at the aquastat sensor is approximately 5° F . less than the set temperature on the MAX TEMP . dial.

29 NOTE: Stirring the starting gel into the pellets usua lly allows the r e to become established quicker . CAUTION: A vapor ash could occur if too much time is allowed to pass before lighting the starting gel. CAUTION: Care must be taken not to get starting gel on your hands or clothing.
30 Fig. 18 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 lled with pellets. The re does not have to be out to scrape the burnpot although it is recommended the boiler be on minimum burn at the time of cleaning.
31 Ash Removal It is reco mmend ed to remo ve the ashe s when the boi ler is not in operati on. This lessens the chances of comin g in contact with hot surfaces. Ashes can be removed while in operation but, extra care must be taken.
32 Cleaning This cleaning should be done after each ton of pellets used. The frequency of this cleaning will be directly related to the quality and the ash content of the pel- lets being used. Keep in mind that the cleaner the heat exchanger surface is kept, the higher the heat transfer efciency will be.
33 Th e boi le r MUS T be OF F and COO L bef ore you shou ld attempt to clean the combustion blower . The wire to the combustion blower doesn’t need to be disconnected during the cleaning process. Loosen the three (3) thumb screws about 4 turns each.
34 1. No pellets in hopper . 2. Firebox draft may be too low for low draft pres- sure switch in feeder circuit to operate.
35 Atmospheric Conversion: Item # 1-00-232200, provides automatic ll, 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.
