1/2" Gas Supply
FP297a
Fig. 4 Typical gas supply installation.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected for
burner or fan servicing. (Fig. 4) See the gas specifica-
tions for pressure details and ratings.
Remote ON/OFF Switch Installation
Do not wire the remote ON/OFF wall switch
for this gas appliance into a 120v power
supply.
1. Thread wire through the electrical knockout located
on either side of the unit. Take care not to cut the
wire or insulation on metal edges. Ensure the wire is
secured and protected from possible damage. Run
one end of the gas control valve and the other end to
the conveniently located wall switch.
2. Attach the wire to the ON/OFF switch and install
switch into receptacle box. Attach cover plate to
switch.
3. Connect wiring to gas valve. (Fig. 5)

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.

location
It is strongly suggested that the wiring of
the EB-1 electrical junction box be carried
1/27/00 djt
out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commenc-
ing this procedure.
The EB-1 electrical junction box has been
supplied standard on the NV360/580 models to allow
for the easy installation of an optional fan kit.
To connect the EB-1 box to the house electrical supply,
follow the steps below:
1. Unscrew the retaining screw from the EB-1 base
plate (fig. 7) and remove the EB-1 assembly from
the fireplace.
2. Remove the front cover of the EB-1 box.
3. Remove the plug socket assembly form the EB-1
box.
4. Feed the supply line in from the outside through the
cable clamp. (Fig. 7)
5. Connect black wire of the power supply line to the
brass screw (polarized) of the socket assembly.
