GENERAL SAFETY INFORMATION

PRECAUTIONS

The operation of any appliance that uses electrical power demands that a number of fundamental safety precautions

be respected.

aDo not allow children or infirm persons to operate

the boiler unsupervised.

aDo not touch the boiler when barefoot or wet.

aNever clean or service the boiler without first discon-

necting it from the mains electricity supply by tur-

ning the main power switch and the control panel

switch OFF.

aDo not tamper with or adjust the safety or control

devices without prior authorisation and instructions

from the boiler’s manufacturer.

aNever pull, disconnect, or twist the electrical cables

coming from the boiler even if it is disconnected

from the mains electricity supply.

aDo no obstruct or restrict the vents in the room

where the appliance is installed. Adequate ventila-

tion is essential for correct combustion.

aDo not expose the boiler to the elements. It is not

designed for use outdoors.

aDo not leave flammable substances or containers in

the room where the boiler is installed.

aDo not dispose of packaging material into the envi-

ronment, or leave it within the reach of children,

since it can become a potential hazard. Dispose of

packaging material in compliance with applicable

legislation.

bAs soon as you open the packaging, check imme-

diately that the contents are all present and unda-

maged. Contact the THERMITAL reseller from

whom you purchased the product if you notice any

problems.

bThis THC V E OIL BLU boiler must be installed by

a legally qualified heating engineer. On completion

of the installation, the heating engineer must issue

the owner with a declaration of conformity confir-

ming that the installation has been completed to the

highest standards in compliance with the instruc-

tions provided by THERMITAL in this instruction

manual, and that it conforms to all applicable laws

and standards.

bThe boiler must only be used for the purpose spe-

cified by THERMITAL and for which it is designed.

The manufacturer declines all responsibility, con-

tractual or other, for damage to property or injury to

persons or animals caused by improper installation,

adjustment, maintenance or use.

bDo not clean the boiler or any of its component

parts with easily flammable substances (e.g. petrol,

alcohol, etc.).

bLow temperature (under-floor) heating systems must

be fed through a circuit fitted with a mixer valve.

PRODUCT DESCRIPTION

SAFETY DEVICES

These THC V E OIL BLU boilers are high efficiency, fuel

oil burning condensing boilers for heating. They can also

produce domestic hot water if an optional remote storage

cylinder is installed.

These boilers may be used as type “C” boilers if the com-

burent air inlet is extended to draw in air from outside the

room where they are installed.

Used in conjunction with suitable optional water circuit

and electrical kits, these boilers can be used to serve up

to two central heating circuits (zones).

The most important technical features of these boilers are:

- The combustion chamber and heat exchange system

are specially designed and shaped to achieve the best

possible volume ratio.

- The primary heat exchanger features vitrified steel

pipes and wave turbulators to recover and transfer a

large proportion of the thermal energy carried by the

combustion fumes.

- The secondary heat exchanger is made from AISI 904L

stainless steel and recovers latent heat from the fumes,

boosting efficiency to up to 100.7% (50°C-30°C).

The exclusively designed heat exchange unit and sec-

ondary exchanger are insulated by ultra-efficient high

density glass wool. The controls and safety devices in the

electronic control panel conform to all applicable techni-

cal and safety standards.

A highly flexible controller permits an additional zone to be

served directly and also permits integration with THERMI-

TAL solar heating systems without additional controllers.

THC V E OIL BLU

boilers are equipped with the following safety devices:

- A safety valve that opens if pressure in the heating

circuit rises above the 3 bar threshold.

- A safety thermostat that forces the boiler to perform

a safety shutdown if temperature exceeds the safety

threshold (110°C).

- A flue gas thermostat in the bottom of the secondary

heat exchanger that triggers a fault condition if flue gas

temperature exceeds 90°C.

- Burner safety device: The fuel oil burner is equipped

with an electronic device to monitor correct implemen-

tation of the selected program. In the event of a fault,

this device sends the control panel a burner lockout

signal and displays a precise diagnostic signal.

You may attempt to restart the boiler after a short delay

(see Preparing for initial start-up).

aNever start the boiler up even for a short period if

the safety devices are not functioning correctly or

have been tampered with.

bSafety devices must only be replaced by

THERMITAL’s Technical Assistance Service using

original spare parts. Refer to the spare parts cata-

logue supplied with the boiler.

Always check that the boiler is functioning correctly after

any repairs.

PRODUCT IDENTIFICATION

DATA PLATE

THC V E OIL BLU

boilers are identified by two plates:

If these plates or any other means of clearly identifying the product are defaced, removed or lost, proper installa-

tion and servicing may be rendered difficult.

- Data plate

This lists the appliance’s technical specifications

and performance data.

- Serial number plate

This is located on the base of the boiler and speci-

fies the serial number, model, furnace power, and

maximum operating pressure.
