HOW THE FURNACE FUNCTIONS PARALLEL INSTALLATION: (See Optional Wiring Diagram, Page 13, Fig. 13) The design is such that when the blower comes on, the blower on the central system also comes on. The blower will only come on when the temperature in the plenum has reached the setting on the blower control. This is to insure that there is sufficient warm air in the system to make it efficient for the unit to operate.
DIMENSIONS OF FURNACE 49-1/8" Figure 1B Figure 1 1400/1500 Models 1500/ 1537G 32-1/8" 24-1/16" 1-3/4" 33-7/8" 40-11/16" 9" CAUTION GASES THAT ARE DRIVEN FROM FRESH COAL MUST BE BURNED OR THEY WILL ACCUMULATE AND EXPLODE. NEVER SMOTHER A FIRE WHEN ADDING FRESH COAL. CAUTION NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR FLAMMABLE LIQUIDS TO START OR "FRESHEN UP" A FIRE IN THE FURNACE.
Locating the Furnace 18" 1. The furnace should be located in the same room as the central system and as close as possible, but not closer than 9". There should be no wall between the furnace and the warm air outlet duct that is connected directly to the warm air outlet plenum of the central furnace. (See Fig. 2) 12" 6" CHIMNEY 9" CENTRAL FURNACE 48" 2. The unit will require installation with the following clearances: Unit to sidewall...............12"(305mm) Unit to backwall............
THIMBLE 6" ELBOW 6" SOLID DAMPER 6" BAROMETRIC DRAFT REGULATOR (OPTIONAL) 6" CHIMNEY CONNECTOR NON-COMBUSTIBLE WALL 6" ELBOW Chimney Connection Fig. 4 MASONRY CHIMNEY Before using an existing masonry chimney, clean the chimney and inspect the flue liner to be sure it is safe to use. Make repairs before attaching the furnace. See page 4, item 5. Look at Fig. 4. The connector pipe and fittings you will need to connect directly to a masonry chimney are shown.
Rules for Connector Pipe Installation 1. The crimped end of the chimney connector fits inside the furnace flue collar. Install additional chimney connectors and elbow with the CRIMPED END TOWARD THE FURNACE. This will allow any condensation in the flue to run back into the furnace. Use 6" dia. steel pipe and elbows for connection to chimney. Never use less than 24 gauge and although blued steel is satisfactory, high temp painted black is much more desirable. 2.
Assembly of Furnace Your furnace requires the following items to be assembled or installed by the service person: Feed Door Pull Handle Feed Door Locking Handle Blowers and Blower Controls Electrical Connections 1. 2. 3. 4. 5. 6. 7. 8. 9. Remove all parts from inside the furnace and inspect for damage, including the firebrick as some breakage could occur during shipment. Assemble the feed door pull handle as shown in Figure 8.
Fig. 11 NOTE: Wire leads from the distribution blower are usually BOTH BLACK. Makes no difference which leads from the motors connects to the corresponding leads coming out of the conduit.
Installation Pipe to combustible: Sides: 21" Back: 18" The installation must be made only on a noncombustible floor. d) Install the smoke pipe connector to the chimney with 26-gauge pipe and elbows (to be purchased separately), maintaining the proper clearances for the specific model. Seal the smoke pipe in the chimney with furnace cement. (The chimney connector shall be securely supported, and joints fastened with sheet metal screws or rivets.
Figure 12 PLENUM 6"18" MIN. TO MIN. CEILING 2" MIN. AIR SPACE REQUIRED BY CODE CENTRAL FURNACE Operating Instructions FUEL, Models 1500 & 1537G Egg size (1-3/16" or larger) bituminous coal for residential furnaces, or any of the specially packed fireplace coals can be used. Coal with a low ash content (2% to 6%) is recommended. Hardwood, 18" to 26" should be split and air dried (seasoned) for 6 months. LIGHTING 1. Set the thermostat on "HIGH" for maximum draft. 2.
Service Hints Do not expect a furnace to draw. It is the chimney that creates the draft. Smoke spillage into the house or excessive build-up of water or creosote in the chimney are warnings that the chimney is not functioning properly. Correct the problem before using furnace. Possible causes are: 4. If the chimney is operating too cool, water will condense in the chimney and run back into the furnace. Creosote formation will be rapid and may block the chimney.
