The CER boilers are suitable for radiators, under-floor heating, added solar heat and domestic hot
water
Consult ATLANTIC BOILERS for suitable circuit arrangements.
1.1 METHOD OF OPERATION
The CER boiler is designed for closed-circuit heating
in both domestic and commercial installations.
Four immersion heaters are positioned within a
cast aluminium-silicium heat exchanger.
Turbulent water flow within the exchanger gives
an optimum rate of heat transfer. With this high heat transfer,
the immersion heaters comfortably work with longer
life at lower temperatures. Another advantage comes
from the modulating output. Conventional electrical
heating switches ON/OFF throughout operation.
Modulating heating means agentle,
varying load on the immersion heaters.
Heating flow and return pipes are positioned
atthe base of the boiler.

3. Power output to pumps & control valve
4. Power input to the boiler
5. Terminals to PT1000 external sensors
6. Stop and limit control terminals
7. Mechanical safety valve
8. Automatic air vent
9. On/offmanual control panel
1.2 IMMERSION HEATERS
Each heater is shaped in a helicoil which
assists the heat transfer.There are four
heaters in the boiler - each powered at 2kW or 3kW
They are screwed down into the four
Tubular shapes of each heat exchanger

1.5 FIXING THE CER BOILER TO THE WALL
1. Remove allen screws A & B from the underside of the casing
2. Lay the boiler body on its back, remove the fascia panel and note
the positions of the wall lugs
3. Fix minimum diameter 8mm screws to the wall.
4. Hang the boiler body from the screws; adjust as necessary.
1.6 HYDRAULIC CONNECTIONS
The CER boiler has 32mm flow (A) and return (B) connections
from the underside.
The flow must be fitted with a safety valve, a shunt pump
A dial thermometer & pressure gauge and an
isolating ball valve. The return, leading into the boiler,
must have an isolating ball valve, a strainer and
a cold feed an expansion connection,
Including the expansion vessel.

1.7 PRECAUTIONS
Fix the boiler firmly to a solid wall
Leave approximately 500mm clearance around the boiler
All electrical wiring must be installed by a qualified electrician
The boiler must receive its power supply through an isolator and a circuit breaker
The power supply cable cross-section must be sized according to the boiler power
The power supply isolator mustbe positioned close to the boiler for safe maintenance work
Live neutral and earth cables must be traced and labelled
The boiler must never be switched on when without casing and fixing screws
Never adjust terminal fixings when boiler alive
Do not operate in manual mode without a competent engineer being present
PUMP AND CONTROL VALVE TERMINALS (On lower left hand side of the boiler)
Heating pump P1 (single phase) is connected to (A) – L N E
Heating pump P2 (single phase) is connected to (B) – L N E

For underfloor heating setting is 0
(C) Variation in electrical power output
(D) Zone 1 setting for heating type
(E) Zone 2 setting for 2nd heating type
(F) Table of boiler power outputs
(G) Table of zone temperatures
2.4 CALIBRATION TO CLOCK CODE A (CONFIG)
0,3, 5, 6, 7 not used
1 one zone underfloor heating (with option DHW)
2 one zone radiators (with option DHW)
4 two zones; one with radiators; one underfloor (with option DHW)
8 manual setting to dry out the boiler & space are dry
9 automatic setting to dry out the boiler & space are dry
SLOPEOF THE WEATHER CURVE – CLOCK CODEB
The Slope Facility (0 to 9) is available (9) for a radiator circuit, (0) for underfloor.
The position (0) lowers flow temperature against outside weather
The position (9) gives maximum flow temperature againstoutside weather
VARIATION IN ELECTRICAL POWER –CLOCK CODE C
Power variation is a percentage of the nominal output – see Table (F).
For example – for a 50% reduction of the power, adjust to setting 4
ZONE SETTINGS – CLOCK CODES (D) and (E)
The two zone flow temperatures can be separately adjusted
The temperature is selected at table G
For example: 2 circuits : 1 radiators and 1 underfloor heating
For zone 1 at 70°C; set clock code D at 7
For zone 2 at 50°C; set clock code E at 3
PLEASE NOTE that OT1 is reserved to the circuit with high temperature, also radiators
PLEASE NOTE that OT2 is reserved to underfloor heating, except for 2 radiator circuits
