NVB Series B-Vent Gas Fireplace

EB-1 Electrical Box

The fireplace, when installed, must be elec- trically connected and grounded in accor- dance with local codes or, in the absence of local codes, with the current CSA C22.1 Canadian Electrical Code.

For USA installations, follow local codes and the National Electrical Code, ANSI/ NFPA No. 70.

It is strongly suggested that the wiring of the EB-1 electrical junction box be carried out by a licensed electrician.

Ensure that the power to the supply line has been disconnected before commenc- ing this procedure.

Once the fireplace is secured, complete wiring the fan kit. Remove knockout in the center of the back of the EB1 and install listed cable clamps. Feed electri- cal wire through cable clamp leaving approximately six

(6)inches of wire exposed through the EB1. Secure cable clamp to the wire.

Attach white wire from power source to one (1) wire of receptacle and secure with a nut. Attach black wire from power source to the other wire of the receptacle and secure with a nut. Be sure nuts are tightened securely.

Secure the EB1 assembly to the inside of the electrical box coverplate using two (2) screws. Attach the cover to the face of the EB1 while being careful to position excess wire completely within the EB1. Attach the cov- erplate to the fireplace. (Fig. 11)
