INSTALLATION #2 Extending the hot air duct from the furnace into the existing plenum will help direct the flow of air from the furnace as well as the flow in the existing furnace. Ducting entering the existing plenum at an angle (approximately 45 degrees) will facilitate air flow from the furnace while diverting air from the existing furnace. (Optional) Back Draft Damper Furnace Existing Furnace INSTALLATION #3 The baffle on this system should be made the full width of the furnace plenum in order to properly direct the air into the distribution ducts. Furnace Existing Furnace Baffle Furnace Existing Furnace Page 10 USSC USSC Page 11 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. The clearances are printed on the label located on the back of the furnace. The chart on this page also states these minimum clearances. Make sure you follow these when choosing your furnace location. Any hot air plenum connection to a furnace must be constructed of metal. NOTE: INSTALLONLYONANON-COMBUSTIBLEFLOOR.

SOLID FUEL FURNACE EXISTING FURNACE EXISTING FURNACE Page 12 USSC FLUE RECOMMENDATIONS WHAT SIZE CHIMNEY SHOULD BE USED? The Chimney size to use is either six (6) or (8) inch round or an 8 x 8" square. If you use a rectangular chimney, the minimum area it may be is 39 square inches. "Class A" chimneys are those made from tile-lined masonry (brick or block) or an independent laboratory approved allfuel factory-built chimney. CAUTION! Only a "Class A", all-fuel chimney intended for use with solid fuel should be used. Chimney experts have determined that the flue termination should be at least 2' above the highest portion of the roof that is within a 10' radius. The flue termination should be at least 3' above the roof line. The termination cap should be designed to inhibit downdrafting without restricting the exhaust discharge. 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 chimney, check first with your local building official to see if this is acceptable. An older chimney, in need of repair, is the GREATEST fire hazard in any installation. STOVE PIPE (FLUE PIPE) CONNECTION The flue pipe you should use is 6" or 8" 24 gauge or heavier steel pipe. When installing the flue pipe, make sure all joints are secured with at least three (3) sheet metal screws. This includes the connection to the flue collar of the furnace. For added protection, use some high temperature furnace cement to seal each joint. The stove pipe should slope upward to the chimney at a rate of 1/2 inch per foot. Any horizontal runs of stove pipe should not exceed six (6) feet and it should be supported every four (4) feet. Note: Flue pipe should be attached inside the flue pipe collar to prevent creosote from running down onto electrical motors. CONNECTION OF FLUE PIPE TO A MASONRY CHIMNEY When connecting flue pipe to a masonry chimney, there are two ways to go: 1. The flue pipe itself can be cemented into the chim ney or; 2. A thimble can be used which is cemented into the chimney, and the flue pipe fits into the thimble. In each case, care must be taken. The outer masonry (brick or block) must be chipped away, and the inner liner must be pierced. The flue pipe or thimble is then inserted flush to the inside face of the tile liner. NOT ANY FURTHER! Use furnace cement or mortar to seal this connection. When connecting the flue pipe, make sure the attachment is secure enough so down draft or "puffs" do not dislodge it. USSC FACTORY-BUILT OR METAL CHIMNEYS If your home has an existing metal chimney, the same rules apply as with masonry chimneys. One thing to be especially aware of is that "Class B" chimneys are for gas appliances only, not solid fuel burners. If purchasing a new package, consult with the dealer. He will provide the necessary parts and instructions for installation. INSTALLING A NEW CHIMNEY When installing a new chimney, whether it be masonry or metal, if possible, it is recommended that it is placed within the house structure. These chimneys remain warmer and, in turn, radiate this warmth into the house. A chimney located outside the house is exposed to cold temperatures which encourages creosote build-up and poor chimney draft. CONNECTING STOVE PIPE TO A METAL CHIMNEY W...
