3.3 INSTALLATION
3.3.1 GENERAL NORMS FOR INSTALLATION OF THE APPLIANCE
•
Installation must be carried out be professionally qualified personnel, following the manufacturer’s
instructions.
•
Professionally qualified personnel means personnel that have specific technical expertise in the sector of
components of heating plants. In any case you may obtain any information that you may require by
calling ROBUR S.p.A.’s Pre-sales Office on 035/888111.
•
Erroneous installation may cause damage to persons, animals or things. The manufacturer may not be
held responsible for such damage.
•
Installation must be carried out in compliance with current national and local norms.
For installation purposes, the following regulations should be respected:
-
The minimum distance of the appliance from the wall behind it should be enough to allow adequate air
renewal (at least 350 mm). The minimum distance from the side walls is indicated in Figure 5.
- The optimum height recommended from the ground to the base of the heater is 2.5 – 3.5 m (see Figure 5).
The heater must NOT be installed at heights of less than 1.8 m from the ground (for models E 32 and E
42), or 2.5 m (for models E 43, E 52 and E 72).
- To obtain maximum comfort and performance from the plant, we recommend that the following rules are
observed:
•
make sure that the flow of air from the appliance does not strike workers directly
•
take into account the presence of obstacles (pillars and suchlike).
•
for better heat distribution, if several machines are installed, create alternating flows of warm air (see
Figure 6).
•
in such cases it may also be a good idea to position the appliances near main doors so that they
perform the additional function of creating an “air barrier” at the moment these doors are opened.
- Do not install Evoluzione series heaters in greenhouses or environments with a high degree of humidity or
other such climatic conditions, as they have not been designed for this type of use.
On the basis of the installation plan, set up the gas and electricity supply lines, as well as the holes for exhaust
gas outlet and combustion air intake (together with the mounting brackets, ROBUR supplies an “installation
template” on which the layout of the holes has been reproduced).
A) Unpack the appliance, taking care to check that it has not been damaged during transport; each appliance
is tested in the factory before being dispatched. Therefore, damage has occurred, tell the transporter
immediately.
B) Fit the mounting brackets, chosen from the three available types (for further information see the paragraph
entitled “Wall installation” on page 18), following the instructions supplied with the accessory.
C) Fix the heater to the bracket, using the screws supplied with the bracket.
D) On the gas supply pipe, provide a gas shut-off valve and a three-piece joint.
E) Check that an adequate gas distribution network exists. In particular, if the appliance is fuelled by:
Natural gas
Make sure that the gas supply pressure from the distribution network, when the appliance is in operation,
is set to the value of 20 mbar (204 mm H
2
O) (with a tolerance from 17 mbar to 25 mbar).
L.P.G. (Propane-Butane mix)
It is essential to fit a first-stage pressure reducer in proximity to the liquid gas tank to reduce pressure to
1.5 bar, and a second-stage pressure reducer for a further reduction from 1.5 bar to 30 mbar (306 mm
H
2
O) in proximity to the heater (with a tolerance from 20 mbar to 35 mbar).
L.P.G. (pure Propane)
It is essential to fit a first-stage pressure reducer in proximity to the liquid gas tank to reduce pressure to
1.5 bar, and a second-stage pressure reducer for a further reduction from 1.5 bar to 30 mbar (306 mm
H
2
O) in proximity to the heater (with a tolerance from 25 mbar to 35 mbar).
