    A HEATMOR™ Stainless Steel Outdoor Furnace should be located with consideration to your neighbor’s property and in accordance with local ordinances. HEATMOR™ Outdoor Furnaces, Model 100 CB, 200 CB and 400 CB are not designed or certified to be located in densely populated areas.

  • Page 17: Warnings And Precautions

    7) Before installing the HEATMOR™ furnace, contact and inform your insurance agent. 8) The HEATMOR™ Outdoor Furnace is to be installed on a concrete base only. Any attempt to place the furnace on any other surface may void the warranty.

  • Page 18: B Electrical

    6) The red wire from the high-limit aquastat on the back of the HEATMOR™ should be wired to the indoor temperature control to override the thermostat. This will dissipate excess heat in the event of a possible malfunction with the HEATMOR™.

    1) Need to have an airtight seal between the concrete base and the perimeter of the firebox base. 2) Need to seal the perimeter of the entire HEATMOR™ so rodents are not able to find a home inside the HEATMOR™.

  • Page 23: E Filling The Heatmor™ Outdoor Furnace Initially With Water

    9) Turn off the source of water. The HEATMOR™ is now full of water and the return line is also full of water and air free, BUT the supply line leading from the HEATMOR™ to the building to be heated is still full of air.
  • Page 24 IS UNSAFE. ALWAYS WEAR PROPER PERSONAL PROTECTIVE EQUIPMENT WHEN WORKING WITH WATER AND CHEMICALS. Maintaining the Correct Amount of Water in the Bladder and in the HEATMOR™ 1) Keep your bladder valve closed when filling your stove with water, but open at all other times.

  • Page 25: G Initial Installation Of Sand

    Initial Installation of Sand Types of sand to use 1) Sand that does not contain clay, rocks or organic matter is appropriate. Use a sand that when packed will not allow air to pass through. Mortar sand, or sand that is used in the redi-mix concrete business is good.

  • Page 26: A Operation

    5) Keep the firebox door, ash auger tube cover cap, top flue cover plate, and the outer door of the HEATMOR™ furnace closed at all times except for servicing and refueling. 6) Keep the locking handle on the outer door locked at all times when not servicing or refueling to reduce the risk of tampering and possible injury.
  • Page 27 15) Wear a particle mask when removing ashes. 16) Ash auger may be hot after removing ashes. 17) In case of power failure, do not open any doors on the HEATMOR™. Monitor the water temperature very closely. Refer to “freeze protection” in this manual.
  • Page 28 Lighting the HEATMOR™ for the First Time When lighting the HEATMOR™ furnace for the first time, all installations must be complete and the furnace must be full of water. It is recommended to open bladder valve, and then build fire to bring the water up to temperature.

  • Page 29: 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 degrees Fahrenheit, the sweating will stop because you are above the dew point.
  • Page 30 Loading a large amount of coal 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.

  • Page 31: F How Does A Fire Burn Out

    What should I burn? This furnace is designed to burn coal. Types of coal allowed to be used include: Pennsylvania anthracite, Eastern Canadian Bituminous and Western Canadian Sub-bituminous. Learn to load the furnace to most appropriately match the heat demand. Warmer outdoor temperatures indicate a need for smaller loads, thereby matching demand to supply and resulting in higher efficiencies.

  • Page 32: M Types Of Coal

    Types of Coal There are three main types of coal approved for use in a HEATMOR™ furnace. They are Pennsylvania anthracite, Eastern Canadian bituminous and Western Canadian sub- bituminous. Coal can vary in size by grade. Use “stove” coal or a similar size. Smaller sizes may restrict airflow and larger sizes may not burn efficiently, if at all.

  • Page 33: Water

    • Do not add water from a well that has recently been “shocked” with chlorine. Water Level Maintenance You can verify the water level of your HEATMOR™ by checking the fullness of the bladder. The water level gauge (“add water” weight) inside the front door of the HEATMOR™ should be up near the bladder, not down near the shelf.

  • Page 34: D Water Additives

    3) Pour the entire contents of the water treatment chemical, as supplied, into the HEATMOR™ furnace. 4) Top up your HEATMOR™ furnace with water and fill the bladder. Refer to “Filling the Bladder Initially” for details or contact your local dealer.

  • Page 36 Freeze Protection Principles of Freeze Protection When the total system is operating as designed, there is no need to add anti-freeze. However if the water in the outdoor furnace is not going to be kept above 50 degrees Fahrenheit in cold weather, freeze protection must be considered. In a properly designed system, the indoor appliances will automatically come on, generate heat, and keep the supply line, return line, and outdoor furnace from freezing by transferring some of the heat generated, back to the outdoor furnace.
  • Page 37 2) Take a funnel and place it into the relief vent pipe. 3) Pour the contents of the freeze protection products, into the HEATMOR™ furnace. Do not pressurize the HEATMOR™; do not attempt to thread fittings onto the relief vent pipe and “pump” additives into the HEATMOR™ under pressure.

  • Page 38: Bladder Assembly

    Bladder Principle of the Bladder The HEATMOR™ is designed to be a semi-closed system. The bladder is a reservoir that accepts the increased volume of water that results when the water within the water jacket expands as it is heated. Similarly, when the water within the water jacket cools down, water is drawn out of the bladder.

  • Page 39: B Bladder Gate Valve And Bladder Hose

    EQUIPMENT WHEN WORKING WITH WATER AND CHEMICALS. 1) Turn off the (green) bladder gate valve located at the front of the HEATMOR™ furnace to the left of the thermometer. 2) Remove the bladder cover plate held in place by two wing nuts.

  • Page 41: Water Jacket

    Supply Line and Return Line Threaded Connectors Principles The HEATMOR™ furnace is designed to draw the supply (hot) water from the bottom of the water jacket. This may seem irregular (people know hot water rises), but this method mixes the water in the water jacket better and often extends pump life. The return (cooler) water connects to the, upper, rear spud of the HEATMOR™.

  • Page 42: Firebox And Other Components

    2) Drain all water and disconnect main power. 3) Remove the total roof of the HEATMOR™. 4) Remove sides of the HEATMOR™. 5) Remove the doors and corners of the HEATMOR™. 6) Remove the insulation. 7) Disconnect plumbing, aquastat and high limit and all electrical from the water jacket.

  • Page 43: Firebox Door

    Firebox Door Principles of the Firebox Door The firebox door is water cooled to prevent warping of the door. It also acts like a water jacket, absorbing heat from the fire, and placing that energy into the water. Being water cooled, the front of the firebox door will never be hotter than the water.
  • Page 44 shut. Make a collar of cardboard between the jaws of two pairs of vice-grips and clamp the door hoses tight at the center point of their length. 4) Loosen the hose clamps and remove the door hoses from the firebox door. 5) Loosen and remove the nuts and bolts holding the firebox door on to the hinge.

  • Page 45: Firebox Door Hoses And Elbows

    Firebox Door Hoses and Elbows Principle of the Door Hoses The door hoses allow water to circulate between the firebox door and the water jacket. Operation of the Door Hoses The door hoses allow water from the water jacket to pass through the firebox door, through thermal siphoning.

  • Page 56: Chimney And Top Flue

    CHAPTER 15 CHIMNEY AND TOP FLUE Chimney Principles The principle of the chimney is to discharge smoke from the flue into the atmosphere. Maintenance Make sure chimney and chimney extensions are clean and in good condition. The chimney may be cleaned from the top with a chimney-cleaning device.

  • Page 57: C Flue

    4) Re-attach the flue cover plate, making sure to tighten the nuts to make an airtight seal. 5) If the HEATMOR™ Furnace unit is shut down for the summer, inspect and clean the flue for the next heating season. Flue Cover Principles The flue cover is airtight and provides access to the flue for cleanout.

  • Page 58: Ashes

    ASHES Ash Management and Ash Removal 1) If ash management is deficient, the HEATMOR™ will not perform to its optimum. It is time well spent to ensure proper ash management. In the long run, the operator will be paid back many times over in higher efficiency and better performance.

  • Page 59: Ash Pan

    3) A proper method of storing the ash auger is to attach a six inch PVC pipe, three feet long, to the side of the HEATMOR™. Storing the auger in the tube will keep it from being frozen into or under snow.

  • Page 60: E Ash Auger Tube Cover Plate

    The ash auger tube is a six inch diameter tube that extends from the rear of the ash pan, to approximately four inches past the cladding of the HEATMOR™. This extension allows placing a container under the tube to catch the ashes.
  • Page 61 NOTE: The temperature reading on the temperature gauge may not coincide exactly with the temperature of the water leaving the back of the HEATMOR™ or the temperature of the water arriving into the building being heated. There may also be small variances between the temperature reading on the temperature gauge at the front of the HEATMOR™...

  • Page 62: Electrical

    Principles The HEATMOR furnace comes with all internal components pre-wired. Provision is made for easy attachment of the main electrical power supply to the HEATMOR™ controls. Electrical outlets at the rear of the HEATMOR™ accommodate plugging in circulating pumps. Electrical Supply Have a licensed electrician make all electrical connections.

  • Page 63: C Double Electrical Outlets At Rear

    “red wire”. The red wire leading from the HEATMOR™ back to the power source Wire Probe can be installed so the electrical power will sound an alarm or will override the comfortable heat settings within the heated building.

  • Page 64: F Front Light And Fan Power Switch

    • This light will then illuminate the area in front of the HEATMOR™. • The light must be turned off for electrical power to be running to the combustion air blowers.

    5) Secure the new roof to the frame of the furnace. 6) Re-seal the lift point and relief vent pipe with high temperature silicone. Sides of the HEATMOR™ Principle of the Sides The sides of the furnace are clad with your choice of steel siding.

  • Page 68: Air Leaks

    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. When the furnace is smoking, cover the chimney and turn off the blower and watch for smoke leaks.

  • Page 69: Water Leaks

    CHAPTER 21 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

  • Page 73 HEATMOR™ Inc. NOTE: To keep the Control Image (water chemical) circulated and properly coated through- out the HEATMOR™ system, it is recommended to start pumps at least once a month for approximately 2 - 3 hours.

  • 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

    Refer to: • Checking for air leaks (Located in Air Leaks). 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.
