manual abstract
5. A listed factory-built wall pass-through system may be purchased and installed according to the instructions packaged with it to provide a safe method of passing the chimney connector through a combustible wall for connection to a masonry chimney. Additional requirements pertaining to Figure 8 and the above wall pass-through systems: 1. Insulation material used as part of wall pass-through system shall be of noncombustible material and shall have a thermal conductivity of 1.0 Btu • in./ft.. • °F (4.88 kg • cal/hr • m. • °C) or less. 2. All clearances and thicknesses are minimums: larger clearances and thickness are acceptable. 3. A chimney thimble, as shown for 3" and 4" above (Parts C and D) shall be for types "3" and 4" connections to facilitate removal of the chimney connector for cleaning. The chimney thimble shall be of ASTM C315 fireclay with 5/8" minimum wall thickness, or material or equivalent durability. The inside diameter of the thimble shall be sized for the proper snug fit of a 6" diameter chimney connector pipe. The thimble shall be installed without damage to the chimney flue. The thimble shall extend through the chimney wall to, but not beyond, the inner surface of the chimney flue and shall be permanently cemented in place with high temperature cement. 4. A chimney connector to a masonry chimney, except for 2" above (Part B), shall extend through the wall pass-through system to the inner face of the chimney flue, but not beyond. It does not have to be fastened in place so long as it cannot accidently be pulled out of the chimney or shoved into the chimney flue. If fasteners are used to secure the chimney connector to a masonry chimney, the fasteners shall not penetrate the chimney flue liner. 5. Any material used to close up any opening for the connector shall be noncombustible. PART E - (Figure 12) In addition to the methods shown by A, B, C, and D of Figure 12, a listed factory-built wall pass-through system may be purchased and installed according to the instructions packaged with it to provide a safe method of passing chimney connector through a combustible wall for a connection to a masonry chimney. CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY WHEN CHIMNEY CONNECTOR DOES NOT PASS THROUGH A COMBUSTIBLE WALL If the chimney connector does not have to pass through a combustible wall to get to a masonry chimney, simply connect the chimney connector directly to the masonry chimney's chimney thimble as described and shown by parts C and D of Figure 12. Remember, the chimney connector should extend into the chimney thimble to the innerface of the chimney flue but not beyond; if the chimney connector is extended through the chimney thimble into the chimney flue, resistance to the flow of smoke and gases up the chimney will occur; that flow resistance will have an adverse affect on the operation and performance of the heater and venting system. 12 13 THERMODISC THERMODISC COVER 4” ELECTRICAL JUNCTION BOX BLOWERS BLOWERS GASKET CLIP NUTS (Not used in the upper center hole.) 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. Remove all parts from inside the furnace and inspect for damage, including the firebrick as some breakage could occur during shipment. 2. Assemble the Damper Box Assembly to the Feed Door and the Black Knob to the Damper Box if not already installed. Ensure the damper operates by sliding the knob up and down. Damper should operate freely with slight tension. 3. Attach feed door locking handle as in Figure 14 with screws and nuts provided. Note: Slotted holes are for adjustment of handle. Adjust handle until some pressure is required to lock feed door during firing sequence. 4. Install the thermodisc on rear of furnace cabinet with the two screws provided. Mount the conduit assembly from the junction box to the thermostat bracket. Crimp the two female terminals to each of the wire leads. Plug the wires to the thermodisc. NOTE: It does not matter which of the two wires plugs to which terminal on the thermodisc. 5. Remove blowers from cartons. Remove junction box cover. Attach clip nuts as in Figure 15. Install blower(s) and gasket(s) with 1/4"-20 x 3/4" bolts as shown. 6. Wire right side blower first (See wiring diagram) and replace cover on junction box on blower. 7. Wire left blower same as above and replace cover. 8. Check operation of shaker grates with grate handle before operating furnace. Figure 15 (Model 1357M has only one blower) Figure 14 Figure 13 14 NOTE: For model 1357M, disregard the wiring (wires M1 & M2) of one blower motor. Wire leads from the distribution blower are usually BOTH BLACK. Makes no difference which leads from the motor(s) connects to the corresponding leads coming out of the conduit.
