800 Series - High Level and Over Door Fan Assisted Heater
INSTALLATION AND OPERATING INSTRUCTIONS
Please read carefully
Personnel - Installation and maintenance must be carried out by suitably qualified personnel.
Application –800 Series High Level Fan Assisted Heater is designed for mounting above a doorway to counteract the
draughts associated with frequently opening doors or for mounting at high level as a space heater in commercial or industrial
premises. They are intended for use normal dry atmospheres and should not be exposed to excessively damp conditions.
Packaging - Carefully unpack the heater and discard the packaging.
Location - When used above a doorway, the heater can be wall or ceiling mounted at a height between 1.8m and 3m above
floor level and a minimum of 300mm from adjacent walls. It must be mounted horizontally. When used as a space heater, it
should be wall mounted at a height between 1.8m and 3m above floor level and a minimum of 300mm from the ceiling and
adjacent walls. Ensure that the airflow through the heater is not obstructed in any way and that no object is closer than 1.5m
from the heater outlet. Do not position the heater beneath a socket outlet.
Mounting - 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 L shaped End Brackets
2 x Plastic Domes
4 x M2.9 screws
6 x M4 bolts
A. Wall mounting above a doorway
Inspect the Fixing Plate. You will see that it has a side with countersunk holes. This is the back of the Fixing Plate and will
eventually be mounted against the wall. Offer the long section of the two End Brackets up to the front of the Fixing Plate so
that the threaded holes align with the countersunk holes. Use the six M4 bolts to fix the End Brackets to the Fixing Plate
ensuring that the 90° bends in the brackets are at the extreme ends of the Fixing Plate. Use the slots in the Fixing Plate to fix
this assembly securely to the wall. Offer the heater up to the brackets, ensuring that the air outlet is pointing vertically
downwards. The plastic spigot in either end of the heater should be firmly located in the 25mm diameter hole in the End
Bracket. Lock the heater in place by using the four screws provided to fit the Plastic Domes to the outside of each End
Bracket.
B. Ceiling mounting above a doorway
The mounting method is as described above (A) with the following changes. 1. The short section of the End Bracket should be
fixed to the Fixing Plate using four M4 bolts (the other two bolts can be discarded). 2. The Fixing Plate should be fixed to the
ceiling rather than the wall.
C. Wall mounting for space heating
The mounting method is as described above (A) with the following changes. 1. The short section of the End Bracket should be
fixed to the Fixing Plate using four M4 bolts (the other two bolts can be discarded). 2. Before locking the heater in place with
the Plastic Domes, the angle of the heater outlet can be adjusted between 90° (horizontal) and 180° (vertically downwards).
Connection
Always check that the supply voltage is the same as shown on the rating label. Connection to the heater should be made
using a suitably rated cable.

General
800 series heaters are fitted with an automatically resetting over temperature protection device. Should an overheat situation
occur the fan will continue to run. In these circumstances, isolate the heater and ensure that no foreign matter is obstructing
the airway through the heater before re-energising. Should the over temperature device operate repeatedly, turn off the heater
and contact a qualified electrician.
Maintenance - This heater is factory assembled and tested with all moving parts being factory lubricated. It is intended for
many years of satisfactory operation without servicing by the user. Maintenance is limited to keeping the heater clean and
preventing an accumulation of dust or other foreign material. Periodically and at least once every year the heater should be
wiped over with a soft dry cloth to remove dust. Any dust build-up in the air inlet and outlet should be loosened with a brush
and a vacuum cleaner applied to the airway to ensure all dust is removed. When the heater is first turned on after cleaning an
unusual odour may be noted. This is a result of dust particles being burnt off the heating element and should not be a cause of
concern.
If in doubt always contact a qualified electrician.
Warranty - Your BN Thermic product is guaranteed for one year from date of purchase. We will repair or replace, at our
discretion, any part found to be defective. We cannot accept any consequential liability. This guarantee in no way prejudices
your rights under common law and is offered as an addition to consumer liability rights.
