EMPIRE FBB4 Gas Fireplace Variable Speed Blower Kit Installation Guide

INSTRUCTIONS MUST BE LEFT WITH OWNER FUTURE REFERENCE AFTER INSTALLATION.

ATTENTION: Install blower assembly before connecting gas inlet supply line
NOTE: Junction box on right side of fireplace must be pre-wired at time of fireplace installation for use with blower assembly. It is recommended that an ON/OFF wall switch be installed that will activate the power supply to the fireplace by a qualified electrician.

WIRING

The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 , if an external electrical source is utilized.

This appliance is equipped with a three-prong [grounding] plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug. For an ungrounded receptacle, an adapter, which has two prongs and a wire for grounding, can be purchased, plugged into the ungrounded receptacle and its wire connected to the receptacle mounting screw. With this wire completing the ground, the appliance cord plug can be plugged into the adapter and be electrically grounded.

STANDARD MILLIVOLT VALVE MODELS

A factory installed junction box is located on the lower right side of the fireplace. Wiring must be fed to the junction box and attached to the receptacle that is provided. Leave approximately 6″ of wire in the junction box for connection.
Attach black wire to one side of the receptacle and white wire to opposite side of receptacle. The ground wire should be attached to the green (ground) screw.

JUNCTION BOX CONNECTIONS

To wire Junction Box Receptacle, remove the tab on the side of the receptacle (hot side) to split receptacle. This will be required to separate blower and valve circuits.
Power for switched and live sides of Duplex Receptacle must come from the same power source. (One circuit breaker on main panel must switch all power off.)
From the wall box to the fireplace a 3-wire conductor with ground is recommended, however (2) two-wire conductors with grounds may be used in place of a 3-wire conductor with a ground if the black wires from the thermostat and blower switch are identified.
Two wall switches, or a wall switch and thermostat may be used to activate the two receptacle plugs independently. Attention: If installed, do not damage gas inlet supply line when blower assembly is inserted into If necessary, removal of the gas inlet supply line may be necessary.

BLOWER MOTOR

The blower motor does not have oiling holes. Do not attempt to oil the blower motor.

BLOWER WHEELS

The blower wheels will collect lint and could require periodic cleaning. If the air output decreases or the noise level increases, it indicates a dirty blower wheel. Remove fan and clean blower wheels
