This unit is equipped with an oxygen depletion safety system (O.D.S.). The
oxygen depletion safety system allows safe vent-free operation. When the
normal oxygen content (20.9%) is reduced to 18%, the pilot and main burner
will turn off and cannot be relit.
When the pilot flame is extinguished by wind or interruption of gas supply, it will
also turn off. Relighting is possible in this condition.
All models, except Mini 8, are fitted with a pressure regulator for Natural Gas.
The thermostat fitted to the models S21 Mini 3 TE and S21 Mini 5 TE, operates
from a maximum to a minimum input power of the main burner, as required by
the temperature in the room.

Installation
This appliance is wall mounted. The minimum clearance from the floor to the bottom
of the heater is 12 cm. However, for a comfortable operation, it is recommended to
install the appliance with a clearance of 25 cm. from floor to bottom.
Never install the heater on the floor.
Fig. 2
Locating the Heater
•Define the height H at which the heater will be installed.
•Draw a horizontal line at a height H + 45,5 cm.

- 5 -
•Mark and drill the holes for the fixing anchors. For model Mini 8 a third hole
must be done. See figure 1c.
•Screw the upper fixing screws some turns in the anchors.
•Separate the front panel of the appliance by removing the two nuts at the
bottom and slide it up. See figure 3
•Hang heater on fixing screws by means of holes provided at the rear of the
heater.
•In model Mini 8, place and fix the bottom fixing screw.
Fig. 3
•Connect the appliance to the gas supply line. The materials used must
conform the local codes and standards.
•Once the appliance is connected, check for leaks. Use liquid detergent in
all joints. Never use a flame to look for gas leaks.
•Reassemble the heater, slide the front panel through the front edges of the
cabinet back as shown in figure 4.
•Place the screws, and fix them.

NOTE: It is normal for a new appliance to give off some odor the first time it is lit.
This is due to the curing of the paint and any undetected oil from the manufacturing
process.
It is recommended to secure a good room ventilation for at least two (2) hours the
first time the heater is used.
Installing the Thermostat Sensor (Fig. 5) - TE Models (with Thermostat)
Once the heater is installed proceed to install the thermostat sensor bracket.
Extract the bulb from the bracket.
The bracket must be fixed horizontally to the wall, with the screws provided. It must
be placed at 1 cm. over the bottom of the heater, and approximately 2 cm. from the
right side of the heater.
When the bracket is fixed to the wall, place the sensor again in the bracket.

Troubleshooting
OBSERVED PROBLEM POSSIBLE CAUSE REMEDY
When ignitor button is pressed,
there is no spark at ODS/pilot 1) Ignitor electrode positioned wrong.
1) Replace ignitor
2) Ignitor electrode broken. 2) Replace ignitor
3) Ignitor electrode not
connected to ignitor cable. 3) Reconnect ignitor cable
4) Ignitor cable pinched or
wet.
4) Free ignitor cable if pinched by
any metal or tubing. Keep ignitor
cable dry.
5) Piezo ignitor nut is loose 5) Tighten nut holding piezo ignitor
to heater cabinet. Nut is located
inside heater cabinet at bottom.
6) Broken ignitor cable 6) Replace ignitor cable
7) Bad piezo ignitor 7) Replace piezo ignitor
When ignitor button is pressed,
there is spark at ODS/pilot but
no ignition.
1) Gas supply is turned off or
manual shutoff valve closed 1) Turn on gas supply or open manual shutoff valve
