Rima Heating Systems S.MAX Series, Installation, Operation & Maintenance Manual

Please note   

System must be connected to open expansion tank for safety reasons.

Any valve must not be connected to safety input and safety output lines.

For increasing safety of the system, by-pass  line must be  installed on the line  between input  and output of 

circulation pumps, as shown in diagrams.

By-Pass line's valve must be kept closed as the boiler is working normally.

By-Pass line's valve can be used in electricity  problems and must be opened if there is a risk of overheating

in system water caused by an electricity cut or problem.

The pipe used in by-pass line must be at least in the diameter of plumbing systems pipe.

UPS (Power Supply Units) can be used for preventing electricity problems.

Please note   

Any problems (malfunctions) caused by boiler clogging with dirt from the heating system and/or malfunctions

induced by clogging, are not covered by the boiler warranty.

Please note   

The filter as well as the sludge trap must be checked and cleaned regularly.

Heating water requirements 

Heating water requirements are specified in EN Standards. When the sum of  concentrations of calcium and 

magnesium  in  the   water  exceeds  1.8  mmol/l ,  additional  non - chemical   treatments   preventing   lime

deposition must be considered  (e.g. Magnetic or electrostatic field treatment).

Boiler location

S.MAX boilers can be located  both on  non - habitable  premises (e.g. in boiler room,cellar,corridor…)  and in

habitable rooms. The room in which the boiler is located  must have a permanent supply of air necessary for

the  combustion  process.  The air must be free of  halogen hydrocarbons and  corrosive vapours, and  must

not  be excessively humid  and dusty. The  room must  be protected  against frost, with ambient temperature

within the range  +5  °C  to  +35 °C and relative humidity not exceeding % 80.

To comply with fire regulations, the boiler must be installed:

• on floor constructed of non-flammable material

• on a  non - flammable material   overlapping  the  boiler footprint  by   20 mm on each side and covering the

entire  depth of the boiler body.

• if  the boiler is installed  in a cellar,  we recommend  to put it on a socket at least 50 mm high, positioning the 

boiler in the middle

boiler in the middle

To comply with  standarts,  at least  600 mm manipulation space  must be  left in front of the boiler. Minimum

distance between the  back  of the  boiler and  the wall  must be also  600 mm,  and a free space  of at least

600 mm  must  be left  between one side of  the boiler and  the wall, to allow access to the rear of  the boiler. 

Fuel  must  not  be   stacked   directly  behind  on  next  to   the  boiler   at  a  distance  less  than   800  mm. 

If   there  are   two  boilers   in  the   boiler  room,  no   fuel  is  allowed  to  be  stacked   between them.  We

recommend  to keep  a minimum  distance  of   800  mm  between  the  boiler  and  fuel  ( 

Fig. 16

 ), or  keep

fuel in a room other than the one in which the boiler is installed.

                 * Do not  put flammable  materials  on top of  the boiler  or  near  the boiler  than  specified  safety 

                   distance.
