manual shutoff gas valve is open,
apply a soap and water solution to
all connections and joints. If bubbles
appear, leaks can be detected and
corrected. DO NOT USE OPEN

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.

OWNER'S MANUAL

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.
