INSTRUCTIONS FOR INSTALLATION
(10) stick through the clamps (11). Attach screw nuts and
washers to the bolts (10) and tighten closely up to the
stop. Then slide the screw spindle (12) into the clamp
(13). Fix the screw nut and washer to the screw spindle
(12) and tighten until the interior is standing parallel to the
wall.
N.B. If easy accessible, e.g. on the ground floor, the out-
let pipe can also be mounted from the outside after the
grid interior sheet and the basket have been disassembled.
STYLE 4-01 and 5-01:
After fitting heat-exchanger fix thermostat phial in clip
provided at rear of backplat (R.H.S.).

Connection of the gas supply

For the different types are the connections as mentioned
below:
• STYLE 3-01 3/8" inner thread
• STYLE 4-01, 5-01 3/8" outer thread
If the supply pipe enters the appliance through the back
plate, press out the disc in the plate. An approved con-
necting tap with coupling should be used in the supply
pipe (For Belgium this should be B.G.V. approved). The
connecting tap with coupling should be fitted outside the
casing. Furthermore:
• Expel all air from the supply pipes/hoses before coupling
to the appliance.
• Do not turn the coupling tap when connecting it to the
gas supply.
• Avoid any pressure on the control tap and pipes.
• Check that all connections are gastight.

Operations

The manufacturer has made the appliance suitable for
the type of gas as indicated on the type identification tag.
Check that the gas pre-pressure and burner pressure cor-
respond with what is stated on the type plate. If necessary,
use the control screw to correct the burner pressure.
The control screw for burner pressure is located behind
the cover on the gas control. This cover can be removed
by removing the screw and clicking loose the lip on the
left side by means of a screwdriver. The thermostat
regulates modulatingly between "full power setting" and
"low power setting" and , when little heat is required, in
two settings, i.e. "low" or "off". In this situation, the pilot
light keeps burning. The "low" setting can only be checked
when the room temperature is higher than
± 15°C (60°F).

The low setting

The low setting has been adjusted to ± 20% of the full
consumption. The low setting screw has been fully tight-
ened and is supplied with the correct low setting bore.
This is not adjustable.

Pilot light burner

Upon delivery, the pilot light burner has the correct con-
sumption by means of a nozzle inside the pilot light burner.
The pilot light burner needs no adjustment.
Putting the casing in its place
From the top, hang the casing over the back sheet, taking
care that the hooks of the casing fit into the notches of
the back sheet and that the operating buttons fit into the
appropriate opening in the casing.
