AND OPERATING PRINCIPLE
05
GAS 120 ACE
OPERATING PRINCIPLE
The products of combustion, in the form of hot flue gases, are forced through the heat
exchanger, transferring their heat to the system water. The flue gas temperature is reduced
to approximately 5°C above the temperature of the system return water then discharged
vertically via the condensate collector, through the flue connection to atmosphere.
The low flue gas exit temperature means there will be a vapour
cloud formed at the flue gas terminal – this is water vapour
formed during the combustion process. If the controls allow the
flow, and therefore return temperature, to fall below dew point
(55°C), this water vapour will begin to condense in the boiler,
transferring its latent heat into the system water and increasing
the output of the boiler, without increasing gas consumption.
Condensation formed within the boiler and flue system is
discharged from the boiler to an external drain via the drain
pan/siphon supplied.
Combustion air is drawn into the closed air box by a variable
speed fan, through the air inlet connection from the plant room
(open flued) or from outside via the concentric flue system
(room-sealed). On the inlet side of the fan is a specially designed
Venturi which is connected to the outlet side of the gas valve.
Depending on the demand (under the dictates of flow/return
sensor and other external/internal control inputs) the electronic
control unit directly monitors the volume of gas and air being
delivered to the premix burner. This mixture is initially ignited by
the combined ignition/ionisation probe which then monitors the
state of the flame. If the flame doesn’t ignite or is unstable, within
the pre-set safety time cycle, the controls will shut the boiler
down (after five attempts) requiring manual intervention to reset
the boiler. The digital display will also indicate a flashing fault
code confirming the reason for the failure.

ENGINEERING SPECIFICATION
GAS 120 ACE
CONSTRUCTION
The boiler shall be a floor-standing type condensing boiler.
The single piece cast aluminium heat exchanger and other
major components are contained within a sealed air box.
The boiler casing is complete with a removable front section
for maintenance purposes. Electrical and electronic controls
are contained within the instrument panel mounted in the
hinged top panel and also the electrical housing mounted
on the inside of the boiler panel.
YDRAULIC, GAS AND
H
FLUE CONNECTIONS
The combined flue gas outlet and combustion air inlet shall
be mounted at the top of the boiler, with the flow, return, gas
and condensate connections located at the rear. The boiler is
suitable for room-sealed or open flue applications. The boiler
is designed for central heating and indirect hot water production
up to four bar working pressure. The boiler is suitable for use
on sealed systems and open vented installations.
OPERATION
The boiler is complete with a modulating control system that
limits the maximum difference in temperature between the
heating flow and return, and the maximum speed at which
the flow temperature increases. The boiler is complete with a
pre-mix burner (NG or LPG) with the gas/air ratio control system
controlled internally. An intelligent, advanced boiler control
continuously monitors the boiler 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
and air/gas supply problems) maintaining boiler output for as
long as possible without resorting to a lock out condition.
Should a negative effect happen in the system the boiler
reduces its output and/or shuts down (shut-off mode), awaiting
the negative conditions to return to normal before restarting.
The control cannot override the standard flame safety controls.
Standard frost protection shall activate below 7°C with stage
one activating the system/shunt pump. Stage two shall activate
below 3°C with boiler switching on to 10°C flow.
CONTROLS
The boiler includes a controls package that allows the actual and
set values to be read and adjusted on the built-in digital display,
which also provides normal operating and fault code indication.

ELECTRICAL
INSTALLATION
GENERAL
The Gas 120 Ace is supplied as standard with electronic control
and flame ionisation safety controls, with a specially designed
microprocessor at the heart of the control system.
SPECIFICATIONS
ELECTRICAL SUPPLY
The Gas 120 Ace must have a permanent 230V – 50Hz single
phase supply rated at 6.3 amps.
BOILER TEMPERATURE CONTROL
The Gas 120 Ace has electronic temperature control with flow
and return temperature sensors. The flow temperature can be
adjusted between 20 and 90°C.
HIGH-LIMIT TEMPERATURE PROTECTION
The high-limit temperature protection device switches off and
locks out the boiler when the flow temperature exceeds the
high-limit set point (adjustable). When the fault is corrected,
the boiler can be restarted by using the reset key on the
control panel.
LOW WATER PROTECTION (FLOW AND CONTENT)
The Gas 120 Ace is supplied with low water protection via
pressure sensor. By modulating back at the moment, the water
flow threatens to fall too low, the boiler is kept operating for as
long as possible. In the event of low flow (F/R ΔT > 45°C) the
boiler will shut off and not lockout. If the boiler is fired dry it will
go to lockout.
ELECTRICAL INSTALLATION
AND ELECTRICAL CONNECTIONS

ELECTRICAL
CONNECTIONS
The Gas 120 Ace 65/90/115 must have a fixed 230v – 50Hz single
phase mains supply. It must be powered by a circuit containing a
double pole switch with an opening distance of 3mm.

FLUE
OPTIONS
The Gas 120 Ace boilers have fan assisted flues supplied as standard, with a concentric flue
outlet/air inlet connection used for room sealed operation, or for open flue (room ventilated)
applications. An optional twin pipe fitting is available for the room sealed CLV system.
The concentric system can be supplied for individual boilers
for horizontal or vertical installation. Because of the excess fan
capacity of the boiler, most flue lengths can be accommodated
(depending on the boiler model and actual route taken), which
enables installers to position the boiler almost anywhere in
the building.
Open flue or room ventilated systems can be installed as
individual or combined flues and should discharge vertically,
with the flue terminating in an optional tapered cone, complete
with bird guard.
Care needs to be taken when siting the actual discharge point.
Please refer to local regulations.

connection. Any condensate which is able to flow back into the
boiler from flue lengths greater than one metre must be discharged
via a condense collector and drain system fitted within one metre of
the boiler flue connection. Make sure that any flue gas outlet pipe
to the boiler has a sufficient gradient (at least 50mm per metre) and
there's a sufficient condensate collector. Where boilers have been
installed on a common open flue system, condensate collectors and
drain systems must be fitted on each individual boiler directly above
the boiler flue connection. Condense siphons must be deep-seal
water type with the discharge taken to a suitable drain point.
Further information regarding flue with dissimilar metals can be
found in BS6644 – 2011 Section 6.10.4.
Concentric room-sealed flue components should not be mixed
with single wall flue components.
Flue components are constructed from a white painted metal
outer and plastic inner.
Flue terminals are painted as detailed in the terminal diagrams.
Plume kit external components are aluminium or plastic and are
painted black.
All flue components are CE approved.
Remeha offers a low loss header solution for single boiler
applications for use with the Gas 120 Ace Boilers. Fitting
a low loss header allows the boiler to maintain the correct
flow of water constantly, ensuring maximum reliability and
efficiency. These accessories are easily integrated into
the boiler. They are supplied with boiler case extension
panels which conceal the low loss header arrangement.

Remeha’s ‘Smart Connection Technology’ modular pipework kit has
been designed to reduce installation time and simplify the planning of
the primary circuit layout, for up to four boilers.
SMART
CONNECTION
TECHNOLOGY
The pipework kit comprises a flow and return
assembly to each boiler which incorporates
a suitably sized circulation pump, safety relief
valve set at three bar and isolation valves.
Each manifold (one per boiler) simply bolts
together at 700mm centres, with a low loss
header and connecting/blanking flanges
completing the installation. The standard
manifold provides connections for both in-line
and back-to-back boilers. Simply blank off the
connections not used with the caps contained
within the kit. The pipework kits have been
designed to operate at a minimum 15ºC ΔT.
