GENERAL DESCRIPTION OF BOILER

The Remeha Gas 610 ECO is a free standing, gas fired
(Natural gas only), fully modulating high efficiency con-
densing boiler. The boiler consists of two modules with
each a heat exchanger, fan and control. Each module
is being delivered fully assembled, plastic wrapped and
crated on a pallet. The sectional cast aluminium heat
exchangers and other major components are contained
within a rigid steel frame with removable casing parts for
maintenance purposes. The frame of each module is fit-
ted with a set of casters to enable the assembled unit to
be easily manoeuvred into position within the plant room
on site with the minimum of effort. All major electrical
and electronic controls are contained within the instru-
ment panel (of each boiler module) mounted on top of
the boiler module at the opposite end to the connections
facing to the front of each module (long side) but can be
rotated 90 towards the short side to suit site location.
o
The boiler consists of two modules, a "left-hand" version
and a "right-hand" version. The service side (with the
inspection hatch of the heat exchanger) of each module
is considered to be the front side of that module (see
par. 4.4).
The flue gas outlet c/w the condensate connections will
be at low level on the same side as the connections.
Combustion air inlet (for room sealed operation) is locat-
ed at the top of the boiler.
The boiler is suitable for room sealed or open flue
applications and have been designed for central heat-
ing and indirect hot water production at working pres-
sures not exceeding 6 bar. It must be installed on a fully
pumped system and is designed for operating pressures
between 0.8 and 6 bar.
The pre-mix gas burners (NG only) with its gas/ air ratio
control system ensures clean, trouble free operation
with higher than average efficiencies of up to 109% Hi
(NCV) in the condensing mode combined with ultra low
NOx and minimum CO emissions.
The standard control package allows for external On/
Off, High Low (volt free switch/s) or modulating control
(0-10V input) of each module. The built in digital display
of each module shows normal operating/ fault code indi-
cation and allows actual and set values to be read and
adjusted.
The intelligent, advanced boiler control ('abc
ously monitors the boiler module operating conditions,
varying the heat output to suit the system load. The
control is able to react to external "negative" influences
in the rest of the system (flow rates, air/ gas supply
problems) maintaining boiler output for as long as pos-
sible without resorting to a lock out condition. At worst
the boiler will reduce its output and/ or shut down (shut
off mode) awaiting the "negative" conditions to return to
normal before re-starting.
The 'abc ' control cannot override the standard flame
®
safety controls.
All Gas 610 ECO boilers are live fired after assembly
to ensure the boiler and controls comply with our strict
quality policy.
The unit has been inspected for compliance with the
essential requirements of the following directives:
- Gas Appliances Directive, no. 90/396/EEC
- Efficiency Directive, no. 92/42/EEC
- EMC Directive, no. 89/336/EEC
- Electrical Low Voltage Directive, no. 73/23/EEC
- Pressure Equipment Directive, no. 97/23/EEC, art. 3,
