  BOILER INSTALLATION

1.1 INSTALLATION 

RECOMMENDATIONS.

The Eolo Mythos 24 2 E boiler has been designed 

for wall mounted installation only, for heating 

environments and production of domestic hot 

water for domestic use and similar purposes.

The place of installation of the appliance and 

relative Immergas accessories must have suitable 

features (technical and structural) such to allow 

(always in safety, efficiency and comfortable 

conditions):

-  installation (according to the provisions of the 

technical legislation and technical regulations);

-  maintenance operations (including scheduled, 

periodic, routine and special maintenance);

- removal (to outdoors in the place for loading 

and transporting the appliances and compo-

nents) as well as their eventual replacement 

with appliances and/or equivalent components.

The wall surface must be smooth, without any 

protrusions or recesses enabling access to the 

rear part. They are not designed to be installed 

on plinths or floors (Fig. 1-1).

By varying the type of installation the classifica-

tion of the boiler also varies, precisely:

- Type B boiler

22

 if installed using the relevant 

terminal for air intake directly from the room 

in which the boiler has been installed.

- Type C boiler

 if installed using concentric 

pipes or other types of pipes envisioned for 

the sealed chamber boiler for intake of air and 

expulsion of flue gases.

Only professionally enabled companies are 

authorised to install Immergas gas appliances.

Installation must be carried out according to 

regulation standards, current legislation and in 

compliance with local technical regulations and 

the required technical procedures.

Attention:

 the manufacturer declines all liability 

for damages caused by boilers removed from 

other systems or for any non-conformities of 

such equipment.
Before installing the appliance, ensure that it 

is delivered in perfect condition; if in doubt, 

contact the supplier immediately. Packing ma-

terials (staples, nails, plastic bags, polystyrene 

foam, etc.) constitute a hazard and must be kept 

out of the reach of children. If the appliance is 

installed inside or between cabinets, ensure suf-

ficient space for normal servicing; it is therefore 

recommended to leave at least 45 cm between 

the upper part of the boiler and the ceiling and 

a gap of 3 cm between the boiler casing and the 

vertical sides of the cabinet. Keep all flammable 

objects away from the appliance (paper, rags, 

plastic, polystyrene, etc.).

Do not place household appliances underneath 

the boiler as they could be damaged if the 

safety valve intervenes (if not conveyed away by 

a draining funnel), or if there are leaks from the 

hydraulic connections; otherwise, the manufac-

turer cannot be held responsible for any damage 

caused to the household appliances.

For the aforementioned reasons, we recommend 

not placing furnishings, furniture, etc. under 

the boiler. 

In the event of malfunctions, faults or incorrect 

operation, turn the appliance off immediately 

and contact an authorised company (e.g. the 

Immergas Technical Assistance centre, which 

has specifically trained staff and original spare 

parts). Do not attempt to modify or repair the 

appliance alone.

Failure to comply with the above implies personal 

responsibility and invalidates the warranty.
• Installation regulations:
  - this boiler can be installed outdoors in a 

partially protected area. A partially protected 

area is one in which the appliance is not 

exposed to the direct action of the weather 

(rain, snow, hail, etc..).

  - Installation in places with a fire risk is pro-

hibited (for example: garages, closed parking 

stalls), gas appliances and relative flue ducts, 

flue exhaust pipes and combustion air intake 

pipes.

  - Installation is prohibited on the vertical 

projection of cooking hobs.

  - Installation is also prohibited in places/en-

vironments that constitute common parts of 

office condominiums such as stairs, cellars, 

entrance halls, attics, lofts, escape routes, 

etc. if they are not located inside technical 

compartments under the responsibility of 

each individual building and only accessible 

to the user (for the features of the technical 

compartments, see the technical standards in 

force).

Attention:

 wall mounting of the boiler must 

guarantee stable and efficient support for the 

generator

The plugs (standard supply) are to be used only in 

conjunction with the mounting brackets or fixing 

template to fix the appliance to the wall;

 they only 

ensure adequate support if inserted correctly (ac-

cording to technical standards) in walls made of 

solid or semi-hollow brick or block. In the case of 

walls made from hollow brick or block, partitions 

with limited static properties, or in any case walls 

other than those indicated, a static test must be 

carried out to ensure adequate support.

N.B.: the hex head screws supplied in the blister 

pack are to be used exclusively to fix the relative 

mounting bracket to the wall.

These boilers are used to heat water to below 

boiling temperature in atmospheric pressure.

They must be connected to a central heating 

system and hot water circuit suited to their 

performance and capacity.
