On VTUT models only
, 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’ clips. Position the end cap with
tube holes beneath the reflector profile at the
burner end with the end cap flanges facing

radiant tubes, locate and position tube couplers
at the end of the tube so that the socket heads
are facing outwards. Tighten clamping bolt
arrangement to secure ensuring the bolts are
not over tightened.
For VTUT tube heaters only
.
For joining U
bend, locate and position tube couplers at the
end of the tubes so that the socket heads are
facing outwards.
Do not fully tighten at this stage.
2.2.5 U Bend.
For VTUT tube heaters only.
Slide U bend
into the open end of the couplers. Tighten all
four clamping bolts to provide a tight grip
between tubes & U tube section.
To avoid damaging the heater whilst
installing we recommend the heater
chassis be suspended prior to fitting 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.

All reflectors must be positioned/
attached to the brackets exactly as
detailed in the assembly drawings.
