INTRODUCTION

 

The New Condens FS Series boilers are fully automatically 
controlled, floor standing, fanned, super efficient condensing 
appliances. 
The Siemens LMS14 Boiler Management Unit (BMU) built 
into the appliance is a comprehensive boiler control unit 
which provides all supervisory and control functions re-
quired for burner operation, space heating and DHW heat-
ing. It also offers modular system extensions in the form of 
integrated communication interfaces. 
Through a sophisticated control system combined with pre-
mix burner technology and an aluminium heat exchanger, 
the boilers are capable of high operating efficiencies of 
98.1% (gross) and low emissions. 
The boilers can draw their combustion air from the room or 
via ducting from outside. 
These boilers are certified to meet the requirements of the 
EC 
Gas Appliance Directive, Boiler Efficiency Directive, EMC, 
Low Voltage Directive and 2009/125/EC Ecodesign Di-
rective. 

FOUNDATION / LOCATION OF BOILER

 

The boiler must stand on a floor which must be flat, level 
and of a suitable load bearing capacity to support the 
weight of  the boiler (when filled with water) and  any     
ancillary equipment.

 

Ideally the boiler should be placed on a plinth exceeding 
the plan  area of the boiler by 75mm on each side and at 
least 100mm high

.

 

The boiler must not be fitted outside.

 

GAS SUPPLY

 

The local gas supplier should be consulted, at the installa-
tion planning stage, in order to establish the availability of 
an adequate  supply of gas.  An existing  service pipe must  
NOT be used without prior consultation with the local gas  
supplier.

 

A gas meter can only be connected by the local gas        
supplier or by a Gas Safe Registered Engineer or in IE by a                   
competent person.

 

An existing meter should be checked, preferably by the gas       
supplier,  to ensure   that the meter is adequate to deal with         
the rate of gas supply required.  A minimum working gas           
pressure of 20mbar MUST be available at the boiler Inlet 
for Natural gas.

 

Do not use pipes of smaller size than the boiler inlet gas              
connection.

 

The complete installation MUST be tested for gas       
soundness and purged in accordance with the appropriate 
standards.

 

Gas Boosters

  

A gas booster is required if the gas pressure       
available at the boiler is lower than that required by 
the boiler manufacturer to attain the flow rate for       
maximum burner input rating.

 

Location of the booster requires careful consideration but       
should preferably be closer to the burner rather than the 
gas meter.

 

Ventilation should also be considered to ensure               

ambient temperature  do not  exceed designed                            
recommendations.   
Further guidance is provided in IGE/UP/2.

 

SAFE HANDLING OF SUBSTANCES

 

No asbestos, mercury or CFCs are included in any part of the 
boiler or its  manufacture.

 

FROST PROTECTION 

The boiler has built into its control system the facility to protect 
the boiler only against freezing. 

The set point for the boilers frost protection can be set via the 
Siemens LMS Controller 

Frost protection is ensured, independent of heat requests or 
connected plant components. Therefore, boiler control checks 
frost protection autonomously and causes the burner to be 
started, if necessary. 

Frost protection for the boiler is activated whenever the boiler 
temperature drops below the frost protection set point. 

 

 

SAFETY 

Current Gas Safety (Installation and Use) Regulations or rules 
in force 

The appliance is suitable only for installation in GB and IE and 
should be installed in accordance with the rules in force. 

In GB, the installation must be carried out by a Gas Safe Reg-
istered Engineer or in IE by a competent person. It must be 
carried out in accordance with the relevant requirements of 
the: 

Gas Safety (Installation and Use) Regulations 

The appropriate Building Regulations either The Building Reg-
ulations, The Building Regulations (Scotland), Building Regula-
tions (Northern Ireland). 

The Water Fittings Regulations or Water byelaws in Scotland. 

The Current I.E.E. Wiring Regulations. 

Where no specific instructions are given, reference should be 
made to the relevant British Standard Code of Practice. 

In IE, the installation must be carried out by a Competent Per-
son and installed in accordance with the current Building Reg-
ulations and reference should be made to the current 

ETCI 

rules for electrical installation. 

The boilers have been tested and conform to EN 15502-1 for 
use with Natural Gas
