If end mouldings (P) have been ordered
(optional item) fit the end mouldings with the
screws provided / quick release clips to the
holes in top of the canopy.
2.2.16 HB Manifold Assembly.
VSO Models ONLY.
After fixing the heaters in
the desired position, the manifold system
requires fitting.
After allowing for a minimum of 75mm (3in) of
penetration of the fitting into the tube, cut the
tubes to the lengths required and remove all
burrs and wipe off any grease or oil with a clean
rag.
Method of jointing aluminium tube
Using the applicator gun exude 4mm diameter
bead of high temperature silicon jointing
compound externally round the end of the fitting
and internally round the end of the tube.
Enter the fitting into the tube using a slight
rotating movement to spread the jointing
compound uniformly until a penetration of 75mm
(3in) is achieved.
Note The silicon jointing compound remains
workable after application for only 5 minutes.
Secure the joint by drilling through the tube and
fitting and fix with three pop rivets at 12 o’clock,
4 o’clock and 8 o’clock positions. 4.8mm
(3/16in) diameter pop rivets are recommended.
