GENERAL
INTRODUCTION
The icos range of boilers are a fully automatically controlled, wall mounted, low water content, balanced flue, fanned, condensing gas boiler. It has full modulating central heating outputs of :
HE12 9.3 kW (32,000 Btu/h) to 12.0 kW (41,000 Btu/h). HE15 8.8 kW (30,000 Btu/h) to 14.6 kW (50,000 Btu/h). HE18 8.8 kW (30,000 Btu/h) to 17.6 kW (60,000 Btu/h). HE24 8.8 kW (30,000 Btu/h) to 23.4 kW (80,000 Btu/h).
Due to the high efficiency of the boiler a plume of water vapour will form at the flue terminal during operation depending on external conditions.
The boiler casing is of white painted mild steel with the user controls capable of being mounted remotely from the boiler, if the option is required.

In GB, the installation must be carried out by a CORGI Registered Installer. It must be carried out in accordance with the relevant requirements of the:
OPERATION
When there is a demand for heat, the heating system is supplied at the selected temperature of between 30oC and 82oC.
The boiler features a comprehensive diagnostic system which gives detailed information on the boiler status when operating, and performance of key components to aid commissioning and fault finding.
SAFE HANDLING
This boiler may require 2 or more operatives to move it to its installation site, remove it from its packaging base and during movement into its installation location. Manoeuvring the boiler may include the use of a sack truck and involve lifting, pushing and pulling.
Caution should be exercised during these operations.
Operatives should be knowledgeable in handling techniques when performing these tasks and the following precautions should be considered:
•Grip the boiler at the base.

The manufacturer’s notes must NOT be taken, in any way, as overriding statutory obligations.
IMPORTANT. These appliances are CE certificated for safety and performance. It is, therefore, important that no external control devices, e.g. flue dampers, economisers etc., are directly connected to these appliances unless covered by these Installation and Servicing Instructions or as otherwise recommended by Ideal Stelrad Group in writing. If in doubt please enquire.
Any direct connection of a control device not approved by Ideal Stelrad Group may invalidate the certification and the normal appliance warranty. It could also infringe the Gas Safety Regulations and the above regulations.
