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.

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

1.3 BOILER CONTROL PANEL (on lower front side of the boiler)
(1) Main Isolator
(2) Manual standby switchreplacing digital control
(3) Manual standby temperature control
(4) Indicators
Red – low water pressure, manual re-set
Green – boiler energised
Single and three phase cable terminals are behind
and on top of the Boiler Control Panel
The fascia panel has to be removed to enable the cable,
to be laid neatly and secured
A is where the external cables enter
B remove the fascia panel to reveal cables

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.
