COILMASTER 60 - 70 - 80 - 100 - 120
General Description
This floor-standing COILMASTER combination
boiler is a compact, low-emission condensing ap-
pliance with a pre-mix burner, a stainless steel heat
exchanger and a lightweight casing. It also includes
a built-in stainless steel coil that allows the instan-
taneous supply of hot water for domestic use.
The fully radial burner ensures a high modulation ra-
tio, combustion stability and very low NOx emissions.
The unique and proven “fire-tube” heat exchanger
offers a large heat exchange surface to optimise
energy and heating efficiency.
The COILMASTER is designed for heating systems
and for on-demand production of Domestic Hot
Water, through the built-in stainless steel coil.
The appliances are built for natural gas but can
be converted to operate with liquid gas (propane),
using an optional conversion kit. The optional kit
installation must take place before commissioning
and comply with applicable local regulations and
standards.
The COILMASTER boilers are able to control 3
heating circuits with mixing functions, through 3
optional extension modules. Each extension mod-
ule requires a power supply and a bus connection.
Refer to
“Optional Modules” on page
I-72
for
more information.
The primary circuit of the appliance
is not
provid-
ed with a built-in circulating pump. Therefore, the
heating system must be equipped with at least one
pump for standard system set up.
COILMASTER boilers can be connected in a cas-
cade configuration, which means that the boil-
ers are connected to the same water circuit and
electronic controller, with one boiler operating as
principal, and the others as subsequent. Refer to
“Boilers in a Cascade System” on page
I-73
for
more information on cascade system possibilities.
Frost Protection
The COILMASTER boilers have a built-in an ti-frost
protection. The pump and the burner are started as
required when the return water temperature drops
below 5°C (as measured by the boiler internal sen-
sor installed on the return circuit).

The pump and/or burner will turn off when the re-
turn temperature reaches the required setpoint.
The anti-frost protection function only protects the
boiler, not the entire system.
Safety Devices
The COILMASTER boilers are equipped with a se-
ries of sensors and switches that provide safety for
your appliance and heating system, such as:
î
Water circuit temperature sensors (supply, re-
turn, system, etc.)
î
Gas pressure switch
î
Flue pressure switch
î
Water pressure sensor
î
Flue temperature sensor
î
Alarm contacts
î
CH and DHW safety valves
The COILMASTER boilers
are not
provided with
the following mandatory safety equipment that the
installer must place in the system, in accordance
with the applicable local standards and regulations:
î
Expansion tank, suitable for the system size
î
Safety group, composed of a safety valve (pres-
sure rating adapted to the system), an automat-
ic relief valve and a manometer
î
Air relief valve(s), at the high point(s) of the system
Optional equipment
Some optional equipment can be used with the
COILMASTER boilers. Please contact your AIC
representative for more information and a list of
available equipment.
To lengthen the life of your boiler and heating
system, in addition to the recommended water
characteristics described in
“Water Quality Re
-
quirements to Prevent Scaling and Corrosion
(Primary Circuit)” on page
I-37,
the following
equipment can be installed in the heating circui
t:
î
Water filter / dirt separator
î
Air separator
î
Low loss header
î
Plate heat exchanger
See
“Requirements for the Hydraulic Circuits”
on page I-32
for more information on this equip-
ment.
