AnthraKing 110 Hot Air Furnace

The 110 model utilizes a single Pocono feeder and operates with the Coal-Trol, more data to be posted soon. (220 Furnace shown)

Specs: 5,000 – 110,000 BTU Input, Height 50”, Depth 36”, Width 29”, Hopper Capacity 200 lbs, 1800 CFM blower, 6” side Vent Flue (can be configured for either side, Weight 600 lbs

Boiler and Hot Air Furnace Efficiency

Full DOE testing has not yet been comleted on the boilers and furnaces, however based on stack temperatures and other test data collected over the past year it appears that the boiers and furnaces are in the 85% to 90% efficiency range

110 boiler Fire Tube Design

There are two configurations for the 110 boiler with two types of economizers used,  The stock Axeman Anderson economizers are left in place for oil operation, the diffuser plate shown to the left is not installed and there are pieces of insulation that cover the coal feeder mechanism and prevent heat loss out the base.  During coal operation special twisted economizers are used including two from which the diffuser hangs.

Furnace Heat Exchanger Design

The 110 model furnace utilizes 20 heat exchanger tubes in it's current configuration and has over 27 square feet of heating surface.  The 220 model furnace has 28 heat tubes and almost 35 square feet of heating surface.  A difuser plate diverts the flmae from direct contact with the tubes on both units

Boiler Testing

Both the 110 and 220 model Boilers have been tested extensively.  The 110 model has been tested utilizing the gas and oil options as well

Furnace Testing

The 220 and 110 Furnaces have been undergoing extensive testing. 

We are currently working to obtain a slot for UL 391 Compliance

Development Activities

We at Leisure Line want to make sure that every product that is released through our dealer network is ready for prime time.  That is why the boiler pictured here has been almost one year in development and is stil undergoing changes to meet ASME certification requirements.  Thank you for your patience!

Boiler and Furnaces can be power vented just as the stoves can, more information to come in the future.

Leisure Line Stoves generate heat through combustion of fuel. The heat is transferred through the heat exchanger and distributed to the conditioned room. The products of combustion, however, must be vented safely out of the structure. In a conventional chimney, venting is achieved by the natural lifting action of the hot combustion gas. New, efficient systems absorb more of the heat in the heat exchanger and produce lower temperature vent gas. Lower temperature gas does not rise as quickly or as reliably as in older, less efficient systems. A power venter uses a motorized blower to vent the products of combustion. A power venter is interlocked with the appliance to ensure that proper draft is achieved.

The SWG combines the motor, blower, and vent hood in one complete, easy to install unit. The SWG mounts on the outside of the building and pulls the combustion gas from the appliance through the outside wall utilizing 100% negative pressure.

Benefits of the SWG Power Venter include:

• 100% Negative pressure in the vent pipe for maximum safety.
• No need to seal vent pipe joints, saving time and money.
• Significantly longer vent lengths than positive pressure, direct vent systems.
• The SWG is recommended by major heating appliance manufacturers.

Planning the Venting System

Location of the termination of the venting system should comply with the National Fuel Gas Code, A.N.S.I. Z223.1, manufacturer's recommendations and/or applicable local codes. See Diagram for typical terminal locations.

1. The exit termination of a mechanical draft system must not be less
   than 7' above grade when located adjacent to a public walkway.
2. The vent termination of a direct vent or sealed combustion
   appliance with an input of 50,000 BTU's per hour or less must be
   located at least 9" from any opening through which vented gases
   could enter the building. With an input over 50,000 BTU's per
   hour, a 1' termination clearance is required. Another term for direct
   vent is sealed combustion.
3. The venting systems with the exception of direct vent appliances,
   must terminate at least 4' below, 4' horizontally, or 1' above
   any door, window or gravity air inlet into the building.
4. The bottom of the vent terminal must be located at least 1' above
   finished grade.
5. A venting system must terminate at least 3' above any forced air
   inlet located within 10'.
6. The vent termination point must not be installed closer than 3'
   from an inside corner of an L-shaped structure.
7. The vent termination should not be mounted directly above or within 3' horizontally from an oil tank vent or gas meter, (not shown)

Extension Kits

The standard SWG Power Venter is designed for walls up to 8" thick. PEK extension kits allow the SWG to be installed into walls up to 16" thick. The PEK kit includes the inner/outer pipe extension and air flow damper.

There are currently over 10 of the new 110K model Dual Fuel boilers sold and in operation at varoius customer locations
