3. LOCATION OF HEATER
When used as a space heater mount at a height of 1.8 –3m above floor level and a minimum of 300mm from the ceiling and adjacent walls.
If the 830T is used as an overdoor heater on an external door we recommend that the heater’s mode is set to mode II so the fan continuously runs
and the heat goes on and off with the thermostat. This will stop the built-in thermostat being unnecessarily activated when the outside door is
opened or heat gets trapped in a small entrance area. See “Section 6 –Changing mode of operation”for more information.
4. MOUNTING INSTALLATION
 IMPORTANT! DO NOT mount heater directly below the socket outlet.
 IMPORTANT! Ensure that the mounting surface / ceiling supports are capable of taking the weight of the heater.
 IMPORTANT! Do not allow any object to come closer than 1.5m to the heater outlet.
 IMPORTANT! Always mount the heater horizontal mounting at any other angle will reduce the heater’s life and invalidate the guarantee.
 IMPORTANT! The air intake and discharge areas must be kept completely clear for a minimum of 1.5m from the front of the heater.
4.1 MOUNTING KIT
The mounting kit supplied with each heater consists of the following items.
1 x Fixing Plate (approximately the same length as the heater), 2 x Small Side Brackets, 2 x Large Side Brackets, 2 x Plastic Domes
4 x M2.9 Self Tapping Screws, 6 x M4 x 10mm Long Pozi Drive Screws and 2 x M4 Lock washers.
4.2 WALL MOUNTING ABOVE AN INTERNAL DOORWAY
Attach the two Small Side brackets to the heater using the Plastic Domes and M2.9 Screws. Make sure both open slots are facing downwards
and the brackets face towards the back of the heater (see Pic 1).
Securely attach the Fixing Plate to the wall. Partially insert M4 screws into the outer two holes in each end of the bracket. Make sure the screw
goes all the way through and the thread is just showing the other side (see Pic 2). The heater with its two end brackets should now be slotted
onto the fixing bracket (see Pic 3). Now tighten up the four end screws and add an additional M4 centre screw and lock washer into the centre
hole at each end of the fixing bracket (see Pic 4). UNDER NO CIRCUMSTANCES MUST THE HEATER BE TURNED ON IF THESE TWO
CENTRE SCREWS AND LOCK WASHERS ARE NOT PRESENT OR TIGHTENED UP.
4.3 CEILING MOUNTING ABOVE AN INTERNAL DOORWAY (See notes above in section 3)
The best method is to use M8 drop rods in the two threaded holes in the top of the heater (drop rods not supplied)
leaving a 300mm gap between ceiling and heater or you can use the supplied brackets but spacing them down
300mm. If mounting using the supplied brackets use the method (section 4.2) above with the exception that you
use the Large Side Brackets and they must face upwards (see Pic5). Do not switch on unless the 2 centre screws
and lock washers are fitted to the side brackets and tightened.
4.4 WALL MOUNTING FOR SPACE HEATING
The mounting method is the same as described above (section 4.2) above with the exception that you use the
Large Side Brackets and they must face backwards (see Pic 6). Do not
switch on unless the 2 centre screws and lock washers are fitted to the side
brackets and tightened. The angle of the heater can be adjusted by
releasing the Plastic Domes by unscrewing the self-tapping screws a half
turn twist the heater to required angle then tighten up the screws. The
heater may only be used between 90° (horizontal) and 180° (vertically
downwards).

6. CHANGING MODE OF OPERATION
The heater has two modes of operation to suit different applications.
These two modes are selected by a switch on top of the heater near the mains
connection box.
Mode I
With the switch on the top of the heater in the “I”position both the heater
elements and the fan turn on and off with the thermostat. This mode is best used
when using the heater as a space heater but may give long periods of on / off
switching when the heater is used as an overdoor heater.
Mode II
With the switch on the top of the heater in the “II”position the fan runs continuously and only the heating elements go on and off with the thermostat.
If you use this heater as an overdoor heater, in a confined space or within 300mm of a ceiling, we recommend you use this mode of operation.
7. CONTROL
Standard control is by the on/off switch located on the right of front grille and by adjusting the electronic thermostat knob.
8. MAINTENANCE
Note: Before examining or carrying out any maintenance ensure the heater has cooled down and is disconnected from the mains supply.
The heaters are intended to operate for many years, problem free. All moving parts are factory lubricated and therefore should require no service.
Maintenance is limited to keeping both the inlet and outlet areas free from any accumulation of dust or any other foreign materials. This is especially
important immediately before the heating season. Any dust build up can be loosened using a brush and a vacuum cleaner applied to the airways to
ensure completed removal of any dust. When the heater is first turned on after cleaning an unusual odour may be noted this is due to the dust
particles which inevitably will be disturbed and will be burnt off from the heating element.
If in any doubt always consult a qualified electrician for advice.
9. AUTO CUT OUT
This heater is fitted with a semi-automatic safety device to prevent overheating. The device will isolate the heating element while the fan continues
to operate. Should this occur, disconnect the heater from the mains supply for a minimum of 5 minutes, check and remove any foreign materials
around the airways. If the heater fails to operate or the safety cut out operates again, turn off the heater and contact a qualified electrician.
