Please, read and understand the manual prior to any
installation.
Please follow the instructions, especially those relatin to the
followin :
the auxiliary securation of burner,
the proper installation of turbulators,
the removing of the film from the reflectors,
the proper sealing of tubes,

1. INTRODUCTION
he appliance should be installed in compliance with the local regulations in force. Only
trained, qualified personnel may install the heater. Before installation, check that the type and
pressure of gas comply with the relevant specifications.
2. ASSEMBLY
1.) Apply sealant uniformly onto the inner part of the expanded pipe in the length of
approximately 80 mm from the end of the tube.
2.) Insert the non-expanded part of the next radiant tube, repeating the process until the
proper shame and length is achieved. Next, secure joints with self drilling and taping
screws (three per joint), placing the screws at 120°.
3.) he turbulator should always be placed in the last tube (the one before the exhaust
system).
Please, note that for some constructions more than one turbulator is to be installed. The
turbulators (provided) have to be riveted to each other and slided into the last radiant
tube (the one before the exhaust system).
4.) After the tubes are assembled, slide the combination hangers and reflector supports into
place. Do not vary the location of hangers any more than ±100mm from the
recommendations. (Refer to Picture on Page 4).
3

5.) Slide the reflectors into place and overlap them 50 mm minium.As the length of reflectors
and radiant tubes changes differently, secure no more than two reflectors together. Secure
the burner side reflector shields using the self drilling and taping screws provided.
Reflector assemblin
1.) Starting point of reflector assembling
2.) Place the reflectors onto each other so that the tabs of the reflectors cover
each other.
4

3.) Next, push up the tabs (two per slots) using a screwdriver at least by 90°.
4.) Connect the reflector supports as per the instructions in Section 2.2. (Page 5).
Four reflector support are provided for the appliance I -DR 54 / OMEGA 9U,
and two reflector support are provided for the applianceI -DR 46 / OMEGA 6U.
Note: he reflectors expand and contract during use.
he installation method presented prevents that reflectors slide off of each other and stick together during
contraction, which would reduce their available space and could lead to the damage of the reflectors.
Always make sure that reflectors can easily move in their supports. If required, the outer edges of the reflectors
can be pushed carefully (about 15 cm before and after the support).
VERY IMPORTANT:Before installation, remove the film from the internal part of the
reflector!!!!!!!
6.) he burner can be secured to the burner tube in two different ways:
a.) Securing to the burner tube with a clamp (normal construction):
5

he clamp is pre-assembled to the burner tube. Without using burner sealing paste, push
the screw (bumper) to the clamp. ighten the clamp screws.
b.) Securing to the expanded tube (e.g. with L configuration):
Push the burner fully into the expanded tube without using sealing paste or clamp. Secure
it with three self drilling and taping screws.
Whichever method is used, always secure the burner with at least two other self
drillin and tapin screws to the burner tube.
7.) Connect the combination hangers to the chains using carabiners.
NOTE: It is practical to assemble the appliance on the floor and then lift the assembled unit
into place using a lifting machine. If this is impossible, the heater can also be suspended in
several parts.
Important: Remove the film from the reflectors before installing the appliance.
2.1 Assembly distances of ‘L’ configuration
6

For OMEGA 3L (3 m design, full length), two combination hangers are enough in the
distance of 1800 mm. Secure the first hanger 700 mm from the front of the burner tube.
2.2 Assembly distances of ‘U’ configuration (example: OMEGA 9U)

3. INSTALLATION, LOCATING
he appliance should be installed in compliance with the local regulations in force(G 638
IIworksheet, 904 worksheet: acceptance of heatin installations, EN 13410, TRGI ...).
Minimum clearances to combustibles for fire prevention:
: depending on output
-0.5 m above the reflector
-0.8 m sideways
-1.5 m downward
-1 m lenghtwise
Minimum an le of elevation of burner tube and radiant tubes
Maximum tilt an le of heater
3.1 SUSPENSION
After defining the
location of hangers,
the appliance should
be suspended using
hangers (e.g. chains) with a minimum length of 400 mm. his is required because of
longitudinal deformation due to thermal expansion. Secure the hangers from the ceiling or
8

roof structure, support bars or scaffolding, next to the wall. Suspension is done through the
burner combination hangers and fastenin eye.
EXAMPLE OF HANGER ARRANGEMENT
4. GAS CONNECTION
he appliance can only be used with the gas type specified on the nameplate.
If the gas supply pressure exceeds 60 mbar, a pressure regulator has to be used. he pressure
regulator can be installed individually for each appliance or centrally. A gas filter is advised to
be installed for thepressure regulator to prevent clogging which might be caused by the
deposits that can occur in the pipes even if they are blown out. he connection to the gas
pipeline should be made from above or from the side as connecting from below enables the
accumulation of contamination.
he thermal expansion of the tube radiant heater has to be taken into consideration when
connecting the gas supply, therefore a flexible hose enabling an expansion of 100 mm should
be used. he tube should not be twisted during installation. Connection is made directly to the
½” connector with external thread. A cock has to be installed before the connecting hose.
4.1 OPERA IONS O BE DONE
-GAS PIPELINE CLEANING
9

Before connecting the appliance to the gas supply system, the gas pipeline should be cleaned
fully and thoroughly.
-GAS IGH NESS ES
Once the appliance is installed, the gas supply pipe should be checked for leakproofness using
one and a half times as great pressure as the permitted value (60 mbar). his should be done
every time the system is disassembled and then assembled.
5. ELECTRIC CONNECTION
he combustion air blower is secured to the burner and power is supplied through the main
feed wire. Both the blower and the gas burner automatics require 230V / 50 Hz mains voltage.
IMPORTANT:
-he burner can be connected to the electric network with the safety connector on the
casing next to the blower.
-Electric cable connection:
with plug or fixed connection
-Supply wire: 3 x 0.75 mm²
-he appliance is phase-sensitive, make sure to follow the connection arrangement below:
-Protection: 2 A electric fuse
-Before replacing a fuse, the appliance should be disconnected from the electric network.
he OMEGA tube radiant heater can be operated in automatic or manual mode:
In manual mode, interrupt power supply manually when the desired temperature is reached.
-several heaters can be connected in one heating zone.
-or switch off all the heaters one by one.
Automatic operation
Automatic operation is regulated by theswitchboard and thermostat preset for a week.When
the preset temperature is reached, the heater is switched off.
We recommend automatic operation.
