SECTION 1 - GENERAL
1.1 INTRODUCTION
The
Vogue Max Combi
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:
26
3.7 to 18kW
32
4.6 to 26kW
40
5.7 to 32kW
Instantaneous domestic hot water (DHW) output is also fully
modulating with a maximum of :
26 26kW
32 32kW
40 40kW
The boiler is supplied fully assembled with DHW plate heat
exchanger, diverter valve, circulating pump, pressure gauge,
pressure relief valve and CH expansion vessel.
Variable CH and DHW temperature controls are fitted on the user
control and the boiler features an optional DHW preheat facility.
The boiler includes as standard:
-
Automatic bypass
-
Boiler frost protection
-
Daily pump and diverter valve exercise.
The boiler casing is of white painted mild steel with a white
polymer front panel.
The boiler temperature controls are located behind the lower
panel on the front of the boiler.
The heat exchanger is manufactured from stainless steel.
The boiler is suitable for connection to fully pumped, sealed
heating systems ONLY. Adequate arrangements for completely
draining the system by provision of drain cocks MUST be provided
in the installation pipework.
The standard configuration of pipework from the boiler is routed
downwards.
The Ideal system filter is supplied with this boiler. Installation
instructions for this are located within the system filter box.
Be sure to follow Ideal system filter installation and maintenance
guide for correct method of installation. Failure to install the
system filter correctly will affect boiler warranty.
1.2 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
only occurs if pre-heat is selected from the menu.
When there is a demand for CH, the heating system is supplied at
the selected temperature of between 30
o
C and 80
o
C, until DHW is
drawn off. The full output from the boiler is then directed via the
diverter valve to the plate heat exchanger to supply a nominal DHW
draw-off of
26
10.6 l/min at 35
o
C temperature rise.
32
13.1 l/min at 35
o
C temperature rise.
40
16.4 l/min at 35
o
C temperature rise.
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
o
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.
1.3 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 personal protective equipment 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.
