The heaters can be delivered with following accessories:
4-way air outlet cones (when in use, never block any of the
outlets), plenum head (when in use, always have at least one
large and one small side opened).

The new head with the exception of the "plenum", may be
connected to new air ducts if the user wishes to satisfy spe-
cific needs. In this case and in particular if the diameter and
length of the ducts have been changed or if the number of
bends has been modified, air output may vary. Consequently
it is very important to check and regulate air output when any
modification is made to air heads or air ducts. In all circum-
stances you must ensure that:
• The fan motor does not absorb more current than the
maximum permitted limit;
• The volume of air flow corresponds to the recommended
level.

CONNECTION TO FLUE

Thermal efficiency and proper functioning are directly rela-
ted to correct draft in the the chimney.
• Make sure distance between heater and chimney is as
short as possible, do not create ciosed angles or chimney
section reductions.
• If the heater is not connected to an outside chimney, it
must be equipped with a vertical steel flue and a draft regu-
lator.
RUNNING THE HEATER
To start the heater
• Set switch (2) on position "O", connect heater to mains
(see model plate for electrical specifications).
• If the heater is to be run under manual control, set switch
(2) on position the burner will start and after a short time of
combustion chamber preheating the main ventilator will start.
• If the heater is to be run under automatic control, set
desired value on selected control, set switch (2) on position
......the heater will now start and stop automatically.
• If after these operations the heater does not run properly,
revert to chapter "OBSERVED FAULTS, POSSIBLE CAUSES
AND REMEDIES" and find out reason of malfunction.
To stop heater
• In manual mode, set switch (2) on position "O" or turn off
control in automatic mode.
• Burner will stop and main ventilator will stop later when
combustion chamber has cooled off.
Warning
Never pull plug to stop heater. Never pull plug
before heater has stopped by itself.
Ventilatlon
To run your heater as a ventilator only, set switch (2) on
position

MAINTENANCE

Troublefree running of your heater requires regular mainte-
nance. Unplug heater before doing any maintenance work.
Cleaning of combustlon chamber and exchanger
This operation must take place at least once a year when
the heating season is over. Excessive sooting is mainly due to
incorrect flue, incorrect burner setting or bad quality fuel.
Excessive sooting can be diagnosed if heater has rough
starts.
Access to exchanger is made via two access doors (one
via air outlet, the other after removal of the body panel op-
posite to the burner). Access to combustion chamber require
removal of burner.
Soot and debris can be removed with a vaccum cleaner.
