THE PERSON(S) WHO INSTALLS THIS APPLIANCE, COMMISSIONS, SERVICES OR CARRIES OUT
ANY REMEDIAL WORK, I.E. ELECTRICAL FAULT FINDING, MUST HAVE SUITABLE
ENGINEERING QUALIFICATIONS.

4. INSTALLATION INSTRUCTIONS
Note:
THIS APPLIANCE MUST BE EARTHED
All electrical wiring must be carried out by a qualified
electrician in accordance with current I.E.E. Regulations
and any Local Regulations that may apply.
Boiler Output
The total heat requirement of the installation should not
exceed the rated output of the boiler:
13.2 kW (45,000 Btu/h) - TRG 45
17.6 kW (60,000 Btu/h) - TRG 60
23.5 kW (80,000 Btu/h) - TRG 80
Central Heating System
The boiler can be used as the heat source for any normal
heating system employing pumped small bore circulation
with radiators, skirting heating, fan convectors or any
other suitable form of heat emitters pump controlled by
room stat and time switch. Ensure that a draincock is fitted
at the lowest part of the system and a suitable safety-
valve is incorporated in the system pipe-work adjacent to
the boiler and before any shut-off valves (Max. setting 35
psi).
The total heating surface recommended when using
radiators is:
21m TRG 45
30m TRG 60
42m TRG 80
This is based on an emission of 160 Btu /sq. ft./hour/100
F diff. An allowance of 2.3 kW (8,000 Btu/h) has been
made for domestic hot water.
Domestic Hot Water System
It is essential that a double feed indirect cylinder comply-
ing with BS 1566: Part 1 is used for domestic hot water
supplies. No responsibility will be accepted by Trianco if
connected otherwise.
Interconnecting pipework between boiler and cylinder
should be at least 28mm or 35mm dependent upon size
of calorifier used and the vertical distance between ther
-
mal centres must not be less than 1m.
Care should be taken to ensure that all pipes have the
necessary fall to ensure correct gravity circulation. It is
important that the primary circuit to the cylinder is per
-
manently open - no from of control must be used to
restrict the circulation.
D.H.W. Temperature Control
If temperature control of the domestic hot water is
required, it is recommended that a mixing valve is used
to blend hot water from the cylinder with a cold supply so
as to provide an acceptable temperature at the taps.
IMPORTANT SAFETY NOTES
Read these instructions before installing your boiler.
IMPORTANT: ISOLATE ELECTRICAL SUPPLY TO
THE BOILER BEFORE CARRYING OUT ANY WORK
The mains supply plug is the primary disconnect
device and must be readily accessible during normal
use.
To maintain the boiler’s high thermal efficiency and reliable
operation, it should be serviced annually by a qualified
engineer, preferably trained and registered.
Electrical work should be carried out by a qualified electrical
engineer.
The boiler can be connected to any normal type of heat
-
ing and indirect hot water system but being a continuous
burning appliance it is essential that a radiator or towel
rail is connected in the gravity circuit to dissipate any
residual heat when the heating pump is off. (see page 7).
The heating system must comply with the latest editions
of British Standards and The Building Regulation, and
Electrical Wiring Regulations BS 7671.
Please note: It is essential in the interest of boiler
efficiency and reliable performance that once the boiler
has been installed it is first commissioned, preferably by
a registered engineer. It is the responsibility of the
installer to ensure that the boiler is commissioned.
Always switch off the electrical supply before removing
any of the covers for cleaning.
If any part of the boiler or its flue is modified, then the
guarantee/warranty will be invalidated.
We recommend that you keep these instructions in a
place near your appliance for easy reference.
Before installing the boiler it is important that these
instructions are carefully read and complied with. The
installer must also be satisfied that the appropriate
sections of the following current issues Standards, Codes
of Practice and Regulations are observed:
‘Installation of domestic heating appliances burning solid
fuel’ British Standard Code of Practice BS 8303.
‘Installation of chimneys and flues for domestic appliances
burning solid fuel’
British Standard BS6461 Parts 1 & 2
‘Forced circulation hot water central heating systems for
domestic premises’ BS 5449.
The Building Regulations and Local Bye-laws, Local
Water Authority Bye-laws.
ELECTRICAL SUPPLY
230V 1 Phase 50Hz (Fused 5 Amp)
Regulations for the electrical equipment of buildings -
published by the Institute of Electric Engineers.
The supply cable to the appliance must be BASEC or
HAR approved
