FLOOR FURNACE LOCATION Choose a central location such as a hallway but where occupant traffic is minimal and where there is at least 18 inches of room from two adjoining sides of the grill to the nearest wall so that occupants may pass without stepping on the gill . See Figure Number 1 . M , ) WALL < Bedroom ' t Bath _ Kitchen 8 " Minilntun Vent Pipe | Bedroom I Living Room ] FIGURE 1 FIGURE 2 Give consideration to available air for combustion , location in relation to chimney or vent system , thermostat location , clearance under floor , clearance to combustibles , and heat circulation . Any open foundation is unacceptable as wind can cause pilot outage and reduced efficiency . Keep furniture , drapes , doors , and other combustible materials at least 12inches from the edge of the gill . Never locate the floor furnace closer than 8 inches to a walt and never in a corner . See Figure 2 . Two adjoining sides of the floor furnace must have a minimum clearance of 18 " . See Figure 1 . After selecting a location in the home , go beneath the floor and check the position of the floor furnace in relation to joists , supporting FLOOR FLOOR columns , electric wires , water pipes and walts . There must be aminhnum of 6 inches clearance between the top of the draft hood and floor _ JOIST FLOOR joists . There must also be at least 6 inches clearance between the FURNACE bottom of the floor furuace and the ground . See Figure 3 . . d _ In order to find the location beneath the floor it may be necessary to drill a 1 / 16 inch hole through the floor approximately in the center of Ground _ , the selected floor furnace location to use as a reference point when Level 6 " Minimum measuring under the floor . FIGURE 3 FRESH AIR FOR COMBUSTION AND VENTING Adequate air for combustion and venting must be provided . Any reduction in the necessary amount of fresh air can result in an oxygen starved flame that emits Carbon Monoxide ( C . O . ) an odorless , colorless gas that can cause serious injury or death . A ventilated crawl space will usually provide enough tiesh air . However , you must check to see that there is 1 square inch of free area of ventilation opening for each 1,000 BTU's input of your floor furnace . EXAMPLE : 50,000 BTU floor furnace 1,000 50 square inches . If another gas burning appliance such as a water heater is installed within the same crawl space or basement , add the B . T . U . ' s of the other appliance to those of the floor furnace before calculating the total ventilation needed . EXAMPLE : 50,000 B . T . U . floor furnace plus 40,000 B . T . U . water heater equals 90,000 B . T . U . ÷ 1,000 90 square inches . To compensate tbr the loss of square inches of ventilation due to the use of louvers , gills , or screens add approximately 50 % to the square inches calculated . Screen all openings with mesh not less than ¼ inch to prevent animals or insects from entering the crawl space . All type " B " vents shall extend in a generally vertical direction with oft ; ets not exceeding 45 degees , except that a vent system having not more than one 60 degee oft ; et may be allowed . Any angle geater than 45 degees t'rom the vertical is considered horizontal . The total horizontal run of a vent plus the horizontal vent connector shall be not geater than 75 percent of the vertical height of the vent . Any ofl ; ets used should be as far above the drafthood as possible to allow a venting action to begin before any restriction is encountered . Page 4

CUTTING THE FLOOR OPENING Consult the specification chart on Page 2 t \ ) r the correct floor opening size for the floor furnace to be installed . Lay out the opening size on the floor by using masking tape or cutting a piece of cardboard to the opening size . The opening must be cut square . If you have determined that there is nothing under the floor to interfere with the installation , you are now ready to cut the opening . Start by drilling 1 / _ i , nch holes inside the lines of each corner . Use a keyhole saw or a properly grounded saber saw to cut along the lines making sure to keep the lines straight and the comers square . If the opening dimensions are not correct , it may be difficult to fit the floor furnace into the opening . Forcing the floor furnace through the opening may create stresses that cause the floor furnace to be excessively noisy . Most installation will require cutting a floor joist . Cut the floor joist JOIST so that double headers of the same size lumber can be used to frame around the floor furnace . Double headers are necessary to maintain DOUBLE the strength of the floor . See Figure 4 . < HEADER FLOOR If the clearance between the bottom of the floor furnace and the m < FURNACE - ' _ ground is not adequate , dig a pit that will provide clearances of at OPENING least 6 inches under the floor furnace , 18 inches on the end where 4 , the gas valve is located and 12 inches on the other three sides . Slope the sides of the pit to prevent dirt fiom caving into the pit . See Figmre5 . FIGURE 4 FLOOR FLOOR i JOIST JOIST FLOOR " w 6 " Minimuln FURNACE i _ \ : e _ t pipe £ _ - " _ _ - M2nuln ' - - t , , _ 12 " FIGURE 5 If there is any possibility that water may accumulate in the pit , a drain must be provided . Ifa drain cannot be provided , fabricate a waterproof pan of at least 16 ounce per square foot sheet copper or a suitable substitute . Size the pan to provide 6 inches clearance to the bottom of the floor fflmace , 18 inches on the side where the gas valve is located and 6 inches on the other three sides . The sides of the pan must extend at least 4 inches above the ground . Anchor the pan to prevent it from floating up against the bottom of the floor furnace when water is present . Failure to do so may result in the pan rising to seal offair for combustion and venting . If this occurs , carbon monoxide ( C . O . ) a colorless , odorless gas that can cause serious injury or death may be formed . SETTING THE FLOOR FURNACE Lay aside the grill and package containing the thermostat , wires , etc . , grasp two opposite sides of the outer casing and lower the floor furnace gently through the opening . Support the furnace evenly by the flange at the top of the outer casing . Trim back carpet , padding , and other types of floor covering so that the entire flange rests directly on the floor . If not evenly supported on all four sides , stresses may be created that cause excessive expansion and contraction noises as the floor furnace heats and cools . Anchor the floor furnace in place by driving two galvanized roofing nails through each side of the outer casing into the double headers approximately 1 inch below the flange . Place the grill into position making sure it lays flat against the outer casing flange . Leave the grill in place until time to light the furnace to keep occupants from thlling into the furnace .

INSTALLING THE DRAFT HOOD The draft hood must be installed in the same atmospheric pressure zone as the combustion air inlet . The draft hood is packed in its o , am carton within GASKET the master pack . Make sure the draft hood received is the correct one for MATERIAL the floor furnace being installed . Included in the carton are two rope - like gaskets and 7 sheet metal screws . Begin by pressing the rope - like gasket material into the groove provided around the two male vent outlets on the floor furnace . See Figure 6 . Slip the two female couplings in the draft hood over the male outlets extending through the outer casing , making sure the gaskets remain in place . Press the draft hood tight against the casing and use the 7 sheet metal screws to secure it tightly . All 7 screws must be used to prevent leakage of vent gases . Never install or operate a floor furnace without a draft hood . To do so could result in serious injury , property damage or death . FIGURE 6 CONNECTINGTHEVENT Refer to the specifications on Page 2 for the correct vent pipe size . Familiarize yourselfwith local codes or contact authorities to determine the approved material and method of installing the vent . NOTE : An existing vent that has worked for years may not be adequate for todays design because of higher efficiency requirements that result in lower stack temperatures . Improper or unsafe venting presents a hazard that may result in property damage , bodily injury or loss of life . Listed below are some guidelines to observe when installing the vent system . 1 . Never reduce the vent pipe to a size smaller than the outlet on the draft hood . 2 . Never run pipe more than 15feet horizontally . 3 . The total horizontal mn of avent plus the horizontal vent connector shall be not greater than 75 percent of the vertical height of the vent . 4 . Slope horizontal pipe upwards at least * / 4inch per lineal foot . 5 . Do not use more than one elbow . An elbow restricts the flow of vent gases by approximately 10 % . 6 . Use anoncombustible thimble when connecting vent pipe to amasonry chimney . 7 . Do not insert vent pipe farther than V4inch into the interior of the chimney . 8 . Single wallpipe must not be used . 9 . Never connect the vent pipe to aw chimney or vent system serving a solid fuel - burning appliance . 10 . If another appliance is being vented through the vent system with the floor furnace , the vent pipe must be increased to compensate for the additional load . 11 . Never install any kind of damper in the vent system . 12 . Do not use transite or any other type of ceramic pipe for venting . Class " B " double wall pipe is acceptable to most codes , and if installed in accordance with the pipe manufacturers instructions provides the safest and most efficient vent system . Class " B " pipe has an integral lock for securing sections together . These locks must be properly fitted together . Fasten pipe to draft hood using at least three self - tapping sheet metal screws at equal intervals around the circumference of the pipe . Support horizontal pipe at three - foot intel - vals with metal strapping attached to joists . The floor furnace you have selected was carefully designed to operate both safely and efficiently when vented with the proper size vent listed t \ _ r each furnace on Page 2 of these instructions . We do not recommend doing so , but if you must vent into a masonry chimney use the following instructions . Continued next page Page 6

CONNECTING THE VENT - Continued I l I l I I I I l m 1 / 4 " I I SAFE UNSAFE RECOMMENDED FIGURE 7A FIGURE 7B FIGURE 7C If the floor furnace is vented into a masonry chimney , the chimney must be inspected to deterlnine that it is clear and free of obstructions and that it is sate for the intended use . The inside of the chimney must be at least 6 inches in diameter or 6 inches by 6 inches if rectangular . Insert the vent pipe into the chimney through a masonry or noncombustible corrosion - resistant thimble of the correct diameter . Do not push the pipe fiartherthan ¼ inch into the inside of the chimney . See Figure 7A . Pushing the pipe farther into the inside of the chimney may cause partial or complete blockage as illustrated in Figure 7B . Even following these instructions you may still have a venting problem because of the larger area to be heated inside the chimney . This could cause pilot outage , odors coming tioln the furnace , or noise due to excessive heat not being vented out of the combustion chamber . If you experience any of these problelns , we recommend running the proper size " B " type vent pipe down the chimney and connecting to the horizontal mn of vent pipe with a 90 - de _ ee elbow inside the chimney . See Fig . 7C . Extend the vent system at least 3 feet above the point where it exits the roof and at least two feet higher than any part of the roof system within 10 feet . Terlninate with a listed or approved cap .

CONNECTING THE GAS PIPING Refer to Figure 11 for the basic fittings you will need at the furnace . 1 . Use black iron or steel pipe and fittings or other pipe and fittings that are approved by local codes . 2 . Use pipe joint compound that is resistant to the GAS VALVE action of Liquefied Petroleum ( L . P ) Gas or to any other chemical constituents of the gases to be TEE conducted through the piping only on male threads . 3 . Use two wrenches when making the connection to the valve to keep from bending the mounting bracket or manifold pipe . Do not overtighten as damage to the valve can occur . 4 . Provide a 1 / 8 " nominalpipe thread ( NPT ) plugged tapping t \ _ r test gauge connection immediately upstream of the gas supply connection to the floor furnace . 5 . Provide a sediment trap at least 6 inches long to trap dirt and moisture . Provide space to permit cleaning or emptying . 6 . Use a ground joint union . 7 . Install an approved manual shut - offvalve . FIGURE 11 ADDITIONAL L . P . GAS REQUIREMENTS Have all connections made at the storage tank by a licensed L . R Gas installer . 9 . Have L . R Installer check all lines , piping , and connections fioln the storage tank to the floor furnace when the floor furnace is connected to the storage tank . 10 . The regulator on the storage tank should be set at 11 inches water column . CHECKING THE GAS PIPING All joints must be tested tbr leaks by applying pressure to the piping system . If the test pressure is equal to or less than L / _ , PSIG the floor furnace must be isolated fioln the gas supply piping system by closing the manual gas shut - offvalve on the floor furnace . If the test pressure exceeds _ / _ P , SIG , the floor furnace and its manual gas shut - offvatve must be disconnected fiom the gas piping systembefore testing . Failure to do so may result in damage to the pressure regulator in the gas valve resulting in overfiring . Overfiring can result in combustion chamber failure , property damage , bodily injury or death . Use a mixture of soap and water or liquid detergent to check each joint . Leaks will be indicated by bubbles forming . Correct even the smallest leak at once . Since some soaps may cause corrosion , or stress cracking , rinse the gas piping exterior with water after testing to remove the soap . WARNING Never use a match , candle , open flame or other method which could provide a source of ignition to test for leaks . To do so may result in property damage , bodily injury or death . ( ; AUTION : Label all wires prior to disconnection when servicing controls . Wiring errors can cause ilnproper and dangerous operation . Verify proper operation after servicing . Page 9

Loosen the screw at the bottom side of the sliding air shutter . Slide the air shutter closed until yellow tips start to appear at the top of the flame . See Figure 19 . ( 75,000 BTU floor furnace has two burners , both of which may need adjustment ) . Now open the shutter slightly beyond the point that the yellow disappears and the flame burns blue . ( See Figure 20 ) . Airborne dust particles may cause flashes or streaks of yellow flame as they are drawn into the flame but will have no effect on the efficiency of the floor furnace . If you are satisfied that the burner is properly adjusted , tighten the set screw to lock the shutter in position . Replace the bottom pan . Check air shutter setting at least twice each season to assure that changing conditions are not causing yellow tipping .
