  • Page 26: C Dew Point

    Just as moisture collects on the inside of a warm house window on a cold outside day, the same thing is occurring inside the HEATMOR firebox. The warm moisture in the smoke is condensing on the cold firebox walls of the HEATMOR. In most typical situations, once the water temperature is above approximately 130...

  • Page 27: D Loading Wood Into The Heatmor

    Loading a large amount of wood into the HEATMOR™ furnace once a day is not always best. We have found that you have a more efficient fire and produce less smoke when you add fuel twice a day. Example: Half of the days’...

  • Page 28: E What Can I Burn

    NOTE: To obtain the high efficiencies that the 400-4S is designed for, please follow these guide lines: The moisture content of wood is very important. Trying to burn “wet” wood is wasteful and not recommended.

  • Page 29: G Types Of Wood

    This means that roughly for every 5 cords of wood you burn at 40% Moisture Content you will waste 1 cord just because your wood was not dry. HEATMOR™ is dedicated to helping you burn your wood cleaner, and more efficiently! We recommend burning wood with a moisture content range of 17-25% in this furnace.

  • Page 30: J Efficiency Measurements And Types Of Fires

    Heating Efficiency - Output Based The percentage of the heat produced that was actually absorbed into the water and transferred into the house from the Heatmor Net Efficiency This is the product of the combustion and heating efficiencies.

  • Page 68: Air Leaks

    Checking For Air Leaks Once your HEATMOR™ system is up and running, we recommend that you conduct an initial check for air leaks from the furnace. To detect an air leak, put some green grass (or something which will create heavy smoke) into the furnace.

  • Page 69: Water Leaks

    CHAPTER 22 WATER LEAKS If you suspect that your HEATMOR™ Stainless Steel Outdoor Furnace has developed a water leak, please contact your local dealer for verification and further details.

  • Page 70: Domestic Coil

    The domestic coil provides a method of heating water indirectly through water-to-water convection. This method of heating needs to be planned from the initial stages of purchasing your HEATMOR™. A HEATMOR™ Outdoor Furnace must be special ordered and manufactured with a special hole at the back of the furnace to accommodate the domestic coil.

  • Page 71: Season Start Up & Shut Down Checklists

    “End of Season Maintenance Checklist,” follow the instructions below: 1. Remove cap from chimney. 2. Build fire in firebox and bring your furnace up to temperature. (Refer to the “Lighting the Heatmor for the first time” section of the Heatmor Operations and Maintenance Manual.)
  • Page 72 Contact your local dealer as to where to have your water tested. Pro- vide the testing person with an amount of water from your HEATMOR™, equal to approximately 20 ounces, in a clean container. The amount of water treatment that has to be added yearly is dependent on how much fresh water you have added to your system since the last test.

  • Page 74: Frequently Asked Questions

    Refer to: • Maintaining the correct amount of water in the bladder and in the HEATMOR™. Q. Why is water coming out of the overflow relief vent pipe? A. When the furnace is initially filled and too much water is in the furnace, it releases through the relief vent pipe when the furnace is up to temperature.

  • Page 75: Firebox And Other Components

    Q. Why am I experiencing an excess build up of creosote in the furnace? A. You more than likely are introducing unwanted draft into the firebox. This may be caused by several things, including a door ajar, ash auger tube cover loose, flipper assembly stuck. If your furnace is in a location where wind may effect the pressure differential across the furnace, it could cause draft to leak past the flipper.
