GAS SUPPLY TESTING

Note: This section is intended as a guide for qualified technicians installing gas to this vent-free firebox.

CAUTION: Do not connect vent-free heater before pressure testing gas piping. Damage to gas valve may result and an un- safe condition may be caused.

The appliance and its shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply piping system by closing manual shutoff valve during any pressure testing of the gas supply piping system at test pres- sures equal to or less than 1/2 psig (3.5kPa).

HARD-WIRING FIREBOX

Model FBPS can be hard-wired to the du- plex outlet located inside the firebox bottom if desired. This allows the blower accessory to be plugged into the duplex outlet.

NOTICE: A qualified electrician must connect electrical wiring to duplex outlet for built-in in- stallation. Follow all local codes. In absence of local codes follow The National Electric Code ANS/ NFPA 70.

ELECTRICAL INSTALLATION

A model GA3500A blower system assembly is available for use with the FBPS vent-free firebox as an optional accessory. This blower is designed to be installed on the wall side of the FBPS firebox, when provisions for a 120 VAC supply connection are made at the end of the cabinet. Use of a blower system other than those manufactured by DESA Interna- tional voids the warranty.

Electrical connections are made within the receptacle with wires that are routed through the bushing provided (see Figure 15). The receptacle may be relocated to either side, when necessary. However, the cover plate must be replaced over the unused access point. Be certain to properly ground the vent-free firebox using the green grounding wire (see Figure 17 on page 12).

Note: A 120V supply connection to the leads to the receptacle must be provided for use with the optional blower kit whether installed during or after initial firebox in- stallation. You may not be able to install a supply connection after the final installation is completed. Refer to Optional Blower As- sembly Installation on page 12 for specifics.
