Part 1: INSTRUCTIONS FOR THE INSTALLER

1. General

The infrared radiant heaters of this series are gas appliances which can operate on
natural or LPG
They conform with the European Norms ( EN 416-1:2009 ) and

The installation of the gas radiant heaters must conform with the current
national/international regulations for gas appliances and take into account the local
Building Regulations and the requirements of the local gas supply company.
Electrical installation, gas and electrical connection of the appliance must be
undertaken by qualified installers and executed in conformity with regulations in
force in the destination country of the goods.

Because there may be local differences in some of the requirements, the following
recommended installation instructions are not binding. Any necessary approval must
therefore be obtained before the installation is carried out.

2. Areas of use

The gas radiant heaters are fully automatic, direct fired appliances for ceiling or wall
mounting.
They are intended for the heating of halls and large rooms by infrared radiation: they
heat, in the same way as the sun's radiation, the body, the floor, the walls and all the
objects which their radiation reaches and which, for their part, absorb a part of the
energy radiated.
The surrounding space and the air are thus only heated minimally by convection by
the warm surfaces and objects.
Thermal inertia is thus practically eliminated.

The radiant heaters are particularly suited for installation in the following spaces:

- with installation heights between 4 and 9 m dependent on heat output (Guidance:

5.5-7 m generally recommended, dependent on model, 4m for very localised
heating, 9m for background heating)

- in which it is not wished to create any air movement

- in which various temperature ranges or heating time cycles are wanted.

Against this, installation is to be avoided in the following cases:

- installation heights under 3 and above 9-10 m

- where inflammable or explosive materials are being used or can arise

- where air flow rates above 2.5 m/s or high air or ground humidity exist
In some individual cases, the installation can still be possible if special approval is
obtained at the appropriate stage in planning.

4. Radiant Unit Construction and Assembly.

The gas radiant heaters are constructed from the following main parts:
gas burner, radiant tube, reflector and flue gas fan.

1. Gas Burner 5. Flue gas fan

2. Gas connection 1/2"BSP 6. Reflector

3. Electrical connection 7. Radiant tube support and
(mains and controls plug) mounting bracket

4. Combustion air intake 8. Radiant tube

As delivered, there are the radiant tubes, reflector sections and a carton containing
the following parts: gas burner, flue gas fan, U-bend,pipe connectors (3/9E, 4E and
L versions), support and intermediate brackets, stirrup clamps and reflector screws.

The radiator is assembled as follows - see the drawing which follows and assembly
diagrams.

4.1. Lay the radiant tubes, with both ends free on the appropriate supports,
preferably under the position where it is to be mounted. Note that one end, the
burner end, has an inner stainless steel tube

4.2. Push the U-bend, with the securing screws upwards, onto the tubes until these
are firmly against the shoulders. Tighten the securing screws firmly!

4.3. Place the support brackets on the tubes at both ends and in the middle, place
the stirrup clamps in place and firmly - maintain the distances indicated .

4.4. Lay the intermediate brackets, fasten with the stirrup clamps: first screw the
lower nuts on as far as the end of the thread, insert the stirrup clamps, tighten the
upper nuts.
Important ! After the stirrup clamps are laid in place, the intermediate brackets must
be able to be moved freely on the pipes!

Remove the protective plastic film from the reflector sections and push them into the
support brackets. Fasten the reflectors to the intermediate brackets with the
provided screws.
If preferred, the reflectors may be fitted after the unit is in place.

4.5. Insert the burner, with the warning lamps downwards, on the pipe until it comes
up against the shoulder. Be sure that the burner is mounted on the pipe with inner
stainless steel tube (look for the inner pipe!). Fasten the clamps.

Important:
Check the alignment of the burner: The burner axis and the pipe axis must

coincide, misalignment of the burner shortens the life of the pipe! If the mounting is
to be at an angle, the burner must be fitted to the lower pipe and vertically
orientated. Check also that there is a minimum separation between the burner box
and the reflector of 5-10cm.

4.6. Insert the flue gas fan into the free end of pipe until it comes up against the
shoulder, arrange the connection socket horizontally or vertically according to the
flue arrangement, fasten the clamp, plug the motor connection into the socket on the
burner housing.
