Wood & Coal Burning Furnace Owners Manual Models: 24A, 30A TESTED TO UL 391 All installations must be made in accordance with local and state codes which may differ from this manual. UNITED STATES STOVE COMPANY 227 Industrial Park Road P.O.
United States Stove Company recommends a Parallel Furnace Installation with direct (ducted) feed or return air to your fur- nace. NOTE: Cold air duct intake must be at least 25% larger than hot air duct outlet.
...to the world of solid fuel heating! Your new furnace has been designed and built with a high grade of materials and the strictest regard to quality. Before you start installing your new furnace, take the time to read these instal- lation and operating instructions.
Rules for the Safe Installation and Operation of Your Furnace... Check local codes, the installation must comply with strict conformance in regard to clearances. The Furnace must be installed on a noncombustible floor. Connect the furnace to tile lined inside masonry chim- ney or approved insulated all fuel prefabricated chim- ney only.

How Your New Furnace Works Unlike conventional heating (gas, oil, electric), wood or coal heating requires more user attention. Your furnace, with its automatic combustion air blower, alleviates the constant need for adjusting the burn- ing rate common to other units on the market. The fire, however, must be started and subsequent fuel added by the user.
Furnace location Before you start! It is very important you check with your dealer, local fire department, or building inspector. They will be able to inform you of any state or local codes per- taining to the location and installation of your fur- nace.
Your furnace is designed to be added on to existing duct work and operate either with or without another heat source such as a gas furnace. The following diagrams illustrate acceptable ways of ducting your furnace. Clearance to Combustible Materials Your Furnace has been tested to determine the SAFE clearances to combustible material.

FLUE RECOMMEND Page 8 UE RECOMMENDA A A A A TIONS UE RECOMMEND UE RECOMMEND UE RECOMMEND Only a "Class A", all-fuel chimney in- tended for use with solid fuel should be used. "Class A" chimneys are those made from tile-lined masonry (brick or block) or an independent laboratory approved all- fuel factory-built chimney.
FLUE RECOMMEND CHIMNEY INSTALLATION With the chimney being the most important part to your installation, great care should be given to its design. MASONRY CHIMNEYS If your intention is to use an existing masonry chim- ney, check first with your local building official to see if this is acceptable.
ASSEMBL ASSEMBL ASSEMBLY ILL ASSEMBL ASSEMBL NOTE: Your furnace may come partially pre-assembled, but in the case that it is not, follow the instructions below. Also use these instructions for future maintenance and disassembly. Drawings and photos are for illustration purposes only. Actual parts may differ. Prior to assembling, place the unit in the general vicinity of the installation.

Push in bypass damper after fire has progressed. Your furnace is capable of putting out many BTU's, so don't fully load your furnace until you have be- come familiar with the operation of the furnace. Keep in mind, a full load will not always give you the best results for your needs.
BURNING COAL Your furnace is capable of burning both Bituminous and Anthracite coal. Anthracite is perhaps the best coal fuel because its long even burn time, high heat output, and cleanliness make it a good choice for the home. However, keep in mind it is a much more difficult fuel to use, requires more care and patience, is not so widely available, and is usually much more expensive than bituminous.

If, however, there is no flame then the fire needs more air from the bottom (unless it is near the end of its burn cycle and needs to be recharged). Only when the coal is burned down to half its origi- nal depth is it time to add fresh coal.
Whenever the loading door is opened, it should be cracked slightly (for about ten (10) seconds) to allow oxygen to enter and burn any combustible gases that are present before fully opening. Failure to do this could result in sudden ignition of the unburned gases when the door is opened. This furnace is equipped with a safety latch system to reduce the rsik of sucjh an ignition.
TROUBLE-SHOOTING, PROBLEM SOLVING FOR YOUR FURNACE Problem: Smoke puffs from furnace. Solution: Check chimney draft. Check for blocked chim- ney or flue pipe. Use mirror to check chimney clearance. Check ash pit - if too full, empty. Make sure furnace room is not too airtight. Make sure all chimney mortar connections are air tight.
