Step 4. FIELD WIRING
CAUTION: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation.
ATTENTION: Au moment de l'entretien des commandes,
étiquetez tous les fils avant de les débrancher. Des erreurs
de cáblage peuvent entraîner un fonctionnement inadéquat
et dangereux.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adéquatement une fois
l'entretien terminé.
CAUTION: Ground supply lead must be connected to the wire
attached to the green ground screw located on the outlet
box. See Figures 27 and 28 on Page 20. Failure to do so will
result in a potential safety hazard. The appliance must be
electrically grounded in accordance with local codes or, in the
absence of local codes, the (USA) National Electrical Code,
ANSI/NFPA 70—latest edition, or the Canadian Electrical
Code, CSA C22.1—latest edition.
Route Cable
NOTE: Electrical wiring must be performed by a qualified electrician.
• Install the strain relief in the hole provided on the right side of
fireplace for the electrical wiring (see Figure 20).
• Either use the intgrated junction box, or position an electrical
junction box (not provided) within reach of the termination wiring
pigtail (see Figure 23 on Page 19). Route the pigtail to the junction
box as the termination is installed.
• Route 14 gauge AWG grounded solid wire Romex
stranded cable (e.g., SJOT) from the fireplace to the newly installed
junction box near the termination. Ensure the cable is safety
plated to prevent damage from framing nails and finish drywall
screws. Route it into the lower control compartment and cut to
length before installing the terminals. Install provided hardware on
the ends of the cable. Cable is not provided. The provided crimp
terminals are intended for use with stranded cable. If using Romex,
connect per National Electric Code or local code.
