Safe Handling - IDEAL HE24 Installation And Servicing

INTRODUCTION
The Esprit range of boilers are wall mounted, full sequence,
automatic spark ignition, low water content, fanned flue, high
efficiency, condensing, combination gas boilers.
Note. Due to the high efficiency of the boiler a plume of water
vapour will form at the terminal during operation.
Central heating (CH) output is fully modulating with a range of
8.8 to 23.4kW (30,000 to 80,000 Btu/h)
Instantaneous domestic hot water (DHW) output is also fully
modulating with a maximum of :
HE24 23.4kW (80,000 Btu/h)
HE30 29.3kW (100,000 Btu/h)
HE35 35.2kW (120,000 Btu/h)
The boiler is supplied fully assembled with DHW plate heat
exchanger, diverter valve, circulating pump, pressure gauge,
safety valve and CH expansion vessel.
Variable CH and DHW temperature controls are fitted on the
user control and the boiler features a DHW preheat facility and
a preheat ON/OFF switch.
The boiler temperature controls are accessible behind the
casing lower door.
The heat exchanger is of cast aluminium.
The boiler is suitable for connection to fully pumped, sealed
water systems ONLY. Adequate arrangements for completely
draining the system by provision of drain cocks MUST be
provided in the installation pipework.
Pipework from the boiler is routed downwards as standard, but
may be routed upwards behind the boiler using the stand-off
frame (supplied in a separate kit).
The boiler includes a filling loop, an automatic by-pass and a
75mm condensate trap with integral siphon. Boiler frost
protection is included as standard.
OPERATION
With no demand for CH, the boiler fires only when DHW is
drawn off, or periodically for a few seconds without any DHW
draw-off, in order to maintain the DHW calorifier in a heated
condition. (This facility can be turned off if required).
When there is a demand for CH, the heating system is
supplied at the selected temperature of between 30
82 C, until DHW is drawn off. The full output from the boiler is
o
then directed via the diverter valve to the plate heat exchanger to
supply a nominal DHW draw-off of
HE24 9.6 l/min at 35 C temperature rise.
o
HE30 12 l/min at 35 C temperature rise.
o
HE35 14.4 l/min at 35 C temperature rise.
o
The DHW draw off rate specified above is the nominal that the
boiler flow regulator will give. Due to system variations and
seasonal temperature fluctuations DHW flow rates/
temperature rise will vary, requiring adjustment at the draw off
tap.
At low DHW draw-off rate the maximum temperature is limited
to 65 C by the modulating gas control.

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.

GENERAL

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.
