INTRODUCTION
●The OPALIS 6 models have a permanent pilot
and a fixed output of 9,65 kW.
●The OPALIS 5 models have a permanent pilot
and a fixed output of 8,70 kW. They may only be
run for short periods.
The OPALIS 6 models are fitted with a flue safety
device that shuts off the appliance in the event of
a problem with the flue system. It is essential, for
correct operation of this device, that the
appliance is correctly flued in accordance with
the latest issue of BS 5440 Part 1.
The OPALIS 5 models are fitted with an
atmospheric control pilot and a safety
mechanism to prevent operation in the event of a
fault or blockage.
These appliances are available in the following
versions :
- normal pressure without taps,
- normal pressure with taps.
These instructions describe how to install and
useSaunier Duvalappliances. Itis importantto
pay attention to the warnings on the packag-
ing and the casing of the appliances, and
follow the information given in this document.
The water heaters are gas-fired appliances pro-
viding instant hot water.
This appliance is of an atmospheric type, i.e. the
air in the premises in which the water heater is in-
stalled, is used for the burner combustion. It is there-
fore important for the installation to be carried out
in compliance with the current Standards, espe-
cially in terms of the ventilation of the premises.
In situations where the appliance may be used
continuously for more than five minutes at a time,
the appliance must be flued in accordance with
the latest issue of BS 5440 Part 1.

WATER HEATER INSTALLATION
LOCATION
●Avoid installing the appliance in a room in which
the air is corrosive or dusty.
●Avoid installing the appliance in close proximity
to a cooking appliance.
●Therecommendedheighttoinstalltheappliance
is 1.5 m (59 in) from the viewing window to the
ground.
●Space required for maintenance :
- each side = 50 mm (2 in)
- base = 150 mm (6 in).
●The appliance must be installed with a minimum
dimension of 20 mm (3/4 in) from the rear of the
appliance to the mounting surface.
INSTALLATION
●Flush out service pipes to remove any foreign
material before connecting to the 15 mm water
inlet elbow on the wall plate.
●Mark the position of the hook which supports the
top of the heater, see diagram 3.
●Temporarily attach the heater to the wall fixing
plate and measure the distance between the wall
and the back of the heater. This will indicate the
lenght of hook required.
●Remove the heater. Drill a 6.5 mm hole in the
wall and insert the wall plug, supplied.
●Screw home the hook and leave it protruding
the correct distance to keep the heater vertical.
●Mount the heater onto the hook and connect
the gas and water unions at the wall fixing plate
using the two washers supplied.
●Tighten up all fittings.
●For installation with a spout - attach the swivel
spout to the spout outlet.
●For multipoint installation - remove the nut and
blanking plate from the multipoint outlet, see
diagram 4.
●Fit the 12 mm copper multipoint outlet
connector and washer.
●Connect the pipe to the remote draw off taps.
