The chimney flue must be calculated on the basis of draught
demand values, mass stream and temperature of exhaust fumes
according to table 1. For the existing chimney, if the draught
value exceeds the value from table 1, provide a regulator
maintaining the negative pressure with a set value with an
accuracy of ± 2Pa.
The maintenance of the chimney draught within the
recommended values is one of the most important factors
guaranteeing that the technical-operational parameters of the
heater will be obtained.
WARNING: If inflammable materials are mounted on the
walls of the room in which the heater is to be installed, it
is prohibited to mount the heater at distances smaller
(measured from the external walls of the most protruding
parts) than the ones given in table 2. The chimney
specialist and fire safety specialist may change or
supplement the relevant provisions.
While determining the minimum distances, the fan unit
must be mounted. Apart from meeting the requirements
related to the minimum distances, the heater should be
installed in such a way as to ensure the free inflow of air to
the fan unit and the outflow of hot air from the device.
Check whether the cleaning and maintenance activities
may be performed
VENTILATION
WARNING: In the room where the heater charging air
for burning from the room and with gravity discharge of
exhaust fumes, is located as well as in the room where
the inlets of exhaust pipes are located, it is not allowed to
use exhaust fans.
The application of individual exhaust fans in rooms
directly adjacent to the room where the heater is installed
may also cause creation of negative pressure and an
uncontrolled outflow of exhaust fumes from the heater into
the room.
In the room where the heater is installed, the gravity
supply-exhaust system must be ensured. This system may
not cause the creation of negative pressure in the room.
The supply system should ensure the inflow of air for
burning in the quantity that is not smaller than 10 m
1kW of installed nominal power of the furnaces, and not less
3
than 20 m /h. per person that is to stay permanently in the
room.
The air grates should be constructed in such a way as
to not be clogged. They should also be placed in such a
way as to not cause draughts. Taking care of the
cleanliness and throughput of the air grates belongs to the
duties of the user.
Do not cover the heater when it is operating.
The appliance may get overheated.
Do not clog the air inlet grates on the fan housing.
Do not use the heater in dusty rooms and such rooms
where petrol, dissolvents, paints or other evaporating
inflammable materials can be found. The operation of the
device may cause explosion of these substances.
Maintain a certain distance of the device from the wall
in accordance with the applicable standards.

ASSEMBLY OF THE FAN UNIT
The fan unit is delivered together with the device in a
separate packaging. The assembly of the fan is presented
in figure 2.
Put the fan unit (3) on one of two assembly flanges (9) of
the heat exchanger body (2) as has been shown in the
figure. Screw in the tapping screw (12), through an
assembly hole in the guard of the fan unit, into the assembly
flange (9).

4 FUNCTIONS
The CT50P air heater is a heating device heating
•
the room in which it is located. The heat is produced by way
of burning fuel process, and transmitted to the room owing
to the forced convection and natural convection.
The assembled fan unit forces out the air flow
through the tubular heat exchanger, in which it is heated.
The heated air flows out on the other side of the device to
the heated room.
Each external surface of the device additionally
gives away the heat by way of natural convection.
Installation of the devices outside is not allowed.
•
CT50P air heater is equipped with ash pan allowing
•
the furnace waste from the burning process – from about 3
burning cycles – to be held. It allows to easily and safely
transfer and sort out its contents.
The smoke conduit placed in the upper part of the
•
device serves the purpose of discharging exhaust fumes
from the device, as well as connecting the chimney.
Doors of the side part of the device allow the fuel to
•
be loaded easily and to ensure the required tightness.
The feet allow the device to be placed steadily in
•
the ground. They transfer the weight of the whole device
with the auxiliary equipment.
