A cap on the end should direct the flue gasses down and away from the structure. See Fig. 5. The maximum horizontal length is 18 feet. The minimum termination height above the...

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. See page 21 for the Draft Test proce...

13 Outside Air To install outside air, use 2 3/4” I.D.galvanized steel flex pipe, part # 2-00-08544 ( 12’ 6” length) or part # 2-00-08545 ( 25’ length) See Fig. 6.

28 8. Turn 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. This is more than just an automatic ignition pellet boile...

29 Operation NOTE: Stirring the starting gel into the pellets usually allows the fire to become established quicker. CAUTION: A vapor flash 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 filled with pellets. The fire does not have to be out to scrape the burnpot although it is recommended the boiler be on minimum burn at the t...

31 maintenance Ash Removal It is recommended to remove the ashes when the boiler 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. Open Ash Door Lift the latch and open the door as shown in fig...

32 maintenance 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 ...

33 maintenance The boiler MUST be OFF and COOL before you should attempt to clean the combustion blower. The wire to the combustion blower doesn’t need to be disconnected during the cleaning process.
