o. Every additional collector pipe

adds nearly on the total height of the installed system.

2.5.5. Sanitary Needs For a Long Boiler Life and Proper Operation

Whether your system will be self operating or in a cascade setup, the installations must always include

Oxygen seperator

Hydraulic header (in PVC circuitry, a plate

heat exchanger should be used)

Silt Trap / Strainer

Expansion vessel (per each boiler)

in order for a long life of your device and the validity of your warranty.

There a shutter valve (manual and/or automatic) between the expansion vessel and the

boiler due to dangerous situations for human health.

Extras / Warnings For Proper Installations

pressure losses of the heat exchanger coupled with the pump characteristic curves can be found in

the further pages of the text.

The con iginated) is in

acidic contamination thus must be neutralized before drainage to earth. For further information

Section 4.2. Condensate Syphon Circuit and Condensate Neutralization

A 24 lt expansion vessel should be connected per an aiM boiler in the primary circuit. The

expansion vessels for the secondary circuit region must be properly selected by the contractor firm.

2.5.6. Minimum Free Space Dimensions To Be Left Between the Boiler and the Walls

The minimum dimensions of free space to be left between the boiler and the walls taking the ergonomy of

the service personnel into account while working is stated in the below image as seen.

The LMS 14 boiler controller card has a frost protection system for a possible situation of water freezing

due to low air temperatures. In order for this property to be active, the system must be connected to

ystem parameters

menu. This advantageous property of the card is advised to be teken into account when to be used in

places like low temperature boiler rooms.

When coaxial flue pipe is used for exhaust and fresh air intake in order to prevent the possibility of

mixing of the flue gas to inhaled (sucked) fresh air, the flue pipe should be at correct distances when

installed from the roof and side walls of the building.
