icos - Installation & Servicing
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.
The heat exchanger is of cast aluminium.
Note.
These boilers cannot be used on systems which include gravity
circulation.
The boilers are suitable for connection to fully pumped, open
vented or sealed water systems. Adequate arrangements for
completely draining the system by provision of drain cocks
MUST be provided in the installation pipework.
OPERATION
When there is a demand for heat, the heating system is
supplied at the selected temperature of between 30
o
C and
82
o
C.
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.
• Be physically capable.
• Use PPE as appropriate, e.g. gloves, safety footwear.
During all manoeuvres and handling actions, every attempt
should be made to ensure the following unless unavoidable
and/or the weight is light.
• Keep back straight.
• Avoid twisting at the waist.
• Avoid upper body/top heavy bending.
• Always grip with the palm of the hand.
• Use designated hand holds.
• Keep load as close to the body as possible.
• Always use assistance if required.
