INSTALLATION

1.1 INSTALLATION 

RECOMMENDATIONS.

The Magis Hercules ErP boiler is designed 

solely for base installations, it is predisposed to 

be coupled with a solar panel system and with 

the Immergas heat pump. 

The electronics allow to manage the three 

systems, with which it produces domestic hot 

water for household and similar purposes, room 

heating and cooling (cooling is performed by the 

heat pump only).
In the event the unit is installed in damp places, 

one must provide an insulation system under-

neath it, to insulate it from the ground.

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.

By varying the type of installation the classifica-

tion of the boiler also varies, precisely:
- 

Type B

23

or B

53 boiler

 if installed using the rel-

evant 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 

sealed chamber boilers for air intake and expul-

sion of flue gases.

Note:

 appliance classification is provided in the 

depictions of the various installation solutions 

shown on the following pages.
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.

Before installing the appliance, ensure that it is 

delivered in perfect condition; if in doubt, contact 

the supplier immediately. Packing materials (sta-

ples, nails, plastic bags, polystyrene foam, etc.) 

constitute a hazard and must be kept out of the 

reach of children. If the appliance is installed in-

side or between cabinets, ensure sufficient space 

for normal servicing; therefore it is advisable to 

leave clearance of at least 40 cm on the right of 

the boiler in order to open the lateral hatch and 

a space of 3 cm between the remaining sides of 

the boiler and the sides of the cabinet. Leave 

adequate space above the boiler for possible 

water and flue connections. Keep all flammable 

objects away from the appliance (paper, rags, 

plastic, polystyrene, etc.).

In the event of malfunctions, faults or incorrect 

operation, turn the appliance off and contact an 

authorised company (e.g. the Authorised Tech-

nical 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: 
  - 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 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

: these boilers are used to heat water 

to below boiling temperature in atmospheric 

pressure.

They must be connected to a central heating 

system and domestic hot water circuit suited to 

their performance and capacity. They must be 

installed in rooms where the temperature can-

not fall below 0°C and must not be exposed to 

atmospheric agents.

N.B.:

 before starting the solar system, the solar 

collector must be covered to protect the ab-

sorber from overheating and the operator from 

scalding. The solar circuit must only be filled 

when the hydraulic system has been completely 

assembled and cannot be started before it has 

been possible to eliminate the heat generated by 

the solar collector. 

Attention:

- To size the solar system, contact a qualified 

heating engineer.

- In the event of installing a heat pump to 

integrate the gas appliance, the installation 

company must also be in possession of the 

requirements of the legislation in force on en-

vironmental protection relating to fluorinated 

greenhouse gasses.
