3.3 Gas Supply Tube and Sensing Tubes
Preparation
Remove the plastic ferrule from the bulkhead connector
on the air duct and discard.
Fix the flared end of the back boiler sensing tube to the
bulkhead connection on the boiler air duct with the
tubing nut provided. Slide the sensing tube mounting
bracket assembly over the back boiler sensing tube and
fix to the casing with the screw provided, see diagram 4.2.
Important. Make sure that the mounting bracket
assembly is pushed back to the fire front face of the
boiler casting and check 3mm distance is achieved and
the back boiler sensing tube does not extend above the
sensing tube bracket assembly, see diagram 4.2.
Note: After fitting the combustion products discharge
safety device sensing tube please refer to the
‘commisioning’ section of the back boiler unit and
relight the boiler to test the device.
Check that the gas service cock is in the Off position, see
diagram 3.4.
The inlet supply tube, back boiler sensing tube assembly
and fire front sensing tube are packed in the supply tube
pack, see diagram 3.1.
This supply tube and fire front sensing tube may need to
be cut, at the plain end, dependent on the model and
position of the back boiler in the opening.

Gas Supply Tube
Measure the distance “C”, see diagram 3.5, from the
front mark “P” on the air duct to the fire front fixing wall face.
Use a straight edge across the opening.
Shorten the plain end of the gas supply tube by the
distance “C”. No shortening is required when mark “P”
is level with the fire front fixing wall face, “C” being zero.
The maximum distance for “C” will be 67mm (2
