2.1 Tools Required.
The following tools and equipment are advisable to complete the tasks laid out in this manual.
Suitable alternative tools may be used.
2.2.3 Brackets
There can be three types of brackets supplied
with these heaters:
• Type ‘A’ are suspending brackets with
reflector fixing points.
• Type ‘B’ are suspending brackets with no
fixing points.
• Type ‘C’ is a centre bracket to retain the
reflector. (certain models only)
Slide the bracket assemblies along to the tubes
to the marked positions in their correct order as
detailed in the assembly drawings. Tighten
clamping ‘U’ bolt arrangement to tubes ONLY
WHERE STATED on the assembly drawings.
2.2.3.1 Tube alignment sections For
VSXE50UT Angle Mounted Installations
ONLY.
To allow for differential expansion of the tubes,
a tube alignment assembly is fitted to the first
2.2 Assembly notes.
2.2.1 Tubes
Identify and position tubes on trestles. For
aesthetics it is advisable to position the tube
seam and coupling fastener so that these
cannot be seen from beneath the heater.
For the 50kW U tube only there are
extension radiant tubes. Join these to the
main tube assembly using couplers as detailed
in section 2.2.4
Mark out the position of the bracket centres
from the dimensions shown on the assembly
drawings.
2.2.2 Turbulators (where fitted)
Insert turbulator(s) into tube(s) ensuring the
correct length and quantity are inserted into
their respective correctly identified tube(s) as
detailed in the assembly drawings.
Please read these assembly notes in
conjunction with the correct assembly
drawings (figs 1 to 3).

2.2.7 End Caps
Position the end cap with no tube holes beneath
the reflector profile at the U bend end with the
end cap flanges facing inwards. Fasten to
reflector using M5 pozi set pin and ‘Z’ clip.
Position the end cap with tube holes beneath
the reflector profile at the burner end with the
end cap flanges facing inwards. Fasten to
reflector using M5 pozi set pin and ‘Z’ clip.
2.2.8 Burner Assembly
Slide the burner assembly onto the RIGHT
HAND TUBE when viewed from above,
ensuring it is fully engaged. Secure with grub
screws.
2.2.9 Heat Exchanger Assembly
Slide the heat exchanger assembly onto the
LEFT HAND TUBE when viewed from above
ensuring it is fully engaged. Secure with pinch
screws.
2.2.10 Detailed Assembly Drawings
The following pages show the technical
dimensional details of the VSXE heaters.
Please note the heater type, length and
reference number from the delivery/advice note
before identifying the correct model drawing.
bracket on the fan side radiant tube. Position U
bolt tube alignment sections over the tube and
through bracket prior to clamping.
2.2.4 U Bend.
For VS(A) ‘U’ tube heaters only. Slide the ‘U’
bend onto the tube ends with the clamping
bolts facing upwards until the predefined stop
position. Tighten clamping bolt arrangement
using 13mm socket and wrench.
2.2.5 Couplers.
For VS(A)LF, VS(A)LH, VS(A)LI and VS(A)
45/50UT tube heaters only. For joining radiant
tubes, locate and position tube couplers at the
end of the tubes so that the socket heads are
facing outwards. Tighten clamping bolt
arrangement to secure ensuring the bolts are
not over tightened.
To avoid damaging the heater whilst
installing we recommend the heater
chassis be suspended prior to fitting reflectors.
2.2.6 Reflectors
After removing the protective plastic coating,
slip the reflector through the brackets until the
locating slots are aligned with the type A
bracket fixing points.
Slide the next reflector through the brackets
and overlap the existing reflector until the
locating slots line up with the same bracket
fixing points Secure overlapped reflectors to
bracket using M6 nuts, bolts and flat mud
washers.
All reflectors must be positioned/
attached to the brackets exactly as
detailed in the assembly drawings.

i.e.;
• Clock is correctly set.
• Heater program is correctly set.
• Required room temp is correctly set
4. Once the heating controller ‘calls for heat’
power will be supplied to the heater(s). The
red neon will then illuminate.
5. After a pre-purge period of 10 seconds the
burner will ignite and the amber neon will
then illuminate.
6. If lockout occurs press the lockout reset
button (if available), or switch off electrical

periods in excess of one week it is highly
recommended that both the gas and the
electrical supplies are turned off.
3.3. Routine Maintenance between Service
Intervals
After ensuring that the heater is cold and
mains electric isolated, cleaning of the
reflectors with a soft cloth and a mild
detergent (non solvent based cleaners only)
in water can be undertaken.
Additional removal of dust from the radiant
tubes, burner and heat exchanger can be
undertaken.
3.4 Frequency of Servicing
The manufacturer recommends that to
ensure continued efficient and safe
operation of the appliance it is
recommended that the heater is serviced
annually by a competent person e.g. every
year in normal working conditions but in
exceptional dusty or polluted conditions
more frequent servicing may be required.
The manufacturer offers a maintenance
service.
