INTRODUCTION
The THELIA 30 E boiler is a wall mounted combina-
tion boiler providing central heating and instantaneous hot water.
The boiler is of the II 2H3 category for use with Natural Gas (G20) as distributed in the United Kingdom,
or Butane (G30), Propane (G31) or Towns gas
(G130).
Boilers burning LPG or similar gases MUST NOT be
fitted in basements or below ground level.
The boiler has a fan assisted balanced flue which
both discharges the products of combustion to and
draws the combustion air from the outside of the
room.
The boiler is suitable for top outlet flue connection
only but, can be fitted with horizontal flue, vertical
flue or twin-pipe flue. Refer to flue catalogue for
further details.
Both the central heating and domestic hot water
temperature are user adjustable from the boiler
control panel.
Domestic hot water demand always has priority
over heating demand.
The boiler is designed for use as part of a sealed
water central heating system with fully pumped circulation. The pump, expansion vessel and associated safety devices are all fitted within the boiler.
The boiler can be installed against either an external wall or on an adjacent inside wall, that is, the
flue system will pass directly to the rear or to either
side to the terminal fitted on the outside wall face.
The installation must be carried out by a competent person in accordance with the relevant requirements of The Building Regulations, The Water
Byelaws, The Building Standards (Scotland) Regulations and any applicable local regulations.
These instructions should be carefully followed for
the safe and economical use of your boiler.
Ancillary equipment
A range of flue accessories are available including vertical flues, twin-pipe flues, bends etc.
For further information contact your supplier.
COMMISSIONING
Gas safety (Installation and Use) Regulations
In your interests and that of gas safety, it is the law
that ALL gas appliances are installed and serviced
by a competent person in accordance with the
above regulations.
Gas leak or fault

CONTROLS AND LIGHTING
Starting the boiler
Before starting the boiler check that:
• The gas meter tap is open.
• The boiler gas service cock is open.
• The boiler is connected to the electrical supply
and turned on.
Setting to SUMMER mode (Hot water only)
• Turn the OFF/Summer/Winter' switch (K) to the
'Summer' position, see diagram 1.
• Turn the domestic hot water temperature control (I) to the desired setting, see diagram 1.
To obtain domestic hot water, open a hot water
tap.
Hot water always has priority over central heating.
DRAINING
Protection against freezing
If the boiler is to be out of use for any long periods
during severe weather conditions, it is recommended that the whole system, including the boiler,
be drained to avoid the risk of freezing.
If in doubt, consult your servicing company.
The THELIA 30 E boiler has a built in frost protection
device that protects the boiler from freezing. If the
boiler is to be left and there is a risk of frost, ensure
that the gas and electrical supplies are left connected and that the OFF/Summer/Winter switch is
left in the'Summer' or 'Winter' position.The frost protection device will light the boiler when the temperature of the boiler water falls below 6°C. When
the temperature reaches 16°C, the boiler stops.
Note: This device works irrespective of any room
thermostat setting and only protects the boiler. Always ensure that adequate frost protection is given
to the entire system where necessary.
Draining and filling
Setting to WINTER mode (Heating and hot water)
• Turn the OFF/Summer/Winter selector switch to
(K) to the 'Winter' position, see diagram 1.
• Turn the central heating temperature control (J)
to the desired setting, see diagram 1.
• Turn the domestic hot water temperature control (I) to the desired setting, see diagram 1.
• Make sure that any external controls are calling
for heat.
The heating system will begin to heat up.
To obtain domestic hot water, open a hot water
tap.
Hot water always has priority over central heating.
Caution: The boiler is installed as part of a sealed
system which must only be drained and filled by a
competent person.
Heating safety valve
CAUTION: A safety valve with a discharge pipe is
fitted to this boiler.
The valve MUST NOT BE TOUCHED except by a competent person. If the valve discharges at any time,
switch the boiler off and isolate it from the electrical supply. Contact your installation/service company.
SERVICING/MAINTENANCE
To ensure the continued efficient and safe operation of the boiler, it is recommended that it is
checked and serviced at regular intervals. The frequency of servicing will depend upon the installation conditions and usage but, in general, once a
year should be enough.
Cleaning
The boiler casing can be cleaned with a damp
cloth followed by a dry cloth to polish.
Do not use abrasive or solvent cleaners.
