Use only copper wire.! WARNINGUse a separate branch electrical circuit with a properly sized fuseor circuit breaker for this furnace. See Table 7 for wire size andfuse specifications. A readily accessible means of electricaldisconnect must be located within sight of the furnace.NOTE: Proper polarity must be maintained for 115--v wiring. Ifpolarity is incorrect, control LED status indicator light will flashrapidly and furnace will NOT operate.J--BOX RELOCATIONNOTE: If factory location of J--Box is acceptable, go to nextsection (ELECTRICAL CONNECTION TO J--BOX).NOTE: On 14” wide casing models, the J--Box shall not berelocated to other side of furnace casing when the vent pipe isrouted within the casing.1. Remove and save two screws holding J--Box. (See Fig. 24.)NOTE: The J--Box cover need not be removed from the J--Boxin order to move the J--Box. Do NOT remove green groundscrew inside J--Box.2. Cut wire tie on loop in furnace wires attached to J--Box.3. Move J--Box to desired location.4. Fasten J--Box to casing with the two screws removed inStep 1.5. Route J--Box wires within furnace away from sharp edges,rotating parts, and hot surfaces.FactoryFactoryInstalledInstalledAlternateAlternateLocationLocationA10291Fig. 24 -- Relocating J--BoxELECTRICAL CONNECTION TO J--BOX6.
