2. Chain drill inside the guide lines on the template and remove brickwork.
Timber framed building
(Must be in accordance with Institute of Gas Engineers
document IGF/UP17)
The Timber Frame Kit supplied with the Turboflue
consists of:
•
Sleeve
•
End
plate
•
O'
ring
•
Insulation
slab
Care must be taken to protect combustible materials from
contact with hot surfaces on the convector box and flue.
Proceed as follows:
1. Mark on the inside wall the centreline of the flue
outlet, which must be central between two
vertical studs and mark a 185mm dia. circle.
2. Drill a pilot hole right through the inside and outside wall on the centreline.
3. With a sharp blade score round the 185mm dia. circle on the plasterboard, crosshatch
within the perimeter of the circle and break out the plasterboard without damaging the
vapour barrier.
4. Cut the vapour barrier 10mm less all round than the hole in the plasterboard and push
back around the hole.
5. Stitch drill ply sheathing and complete the hole with a pad saw.
6. From the outside, position the template provided over the pilot hole and mark on the
wall the positions of the fan unit fixing holes.
7. Chain drill inside the guide lines on the template and remove brickwork.
8. Fit the 180mm dia. sleeve from the inside, cut to length to ensure that it does not
protrude more than 10mm into the cavity. Use flexible mastic to secure.
9. Push the endplate into position. (See Fig. 6)
10. Mark out on the inside wall the centreline of the 20mm dia. hole (See Fig. 3, lower left
hand view).
11. Drill through the inner skin 20mm dia.
12. Cut the 20mm dia. plastic conduit to length and fit the 'O' ring supplied to locate in the
centre of the cavity to form a drip collar.
13. From the outside insert the plastic conduit through the hole in the inner wall.
IMPORTANT: The top, rear and sides of the appliance must be
covered with a 25mm minimum thickness of fibreglass insulation.
Installation of major components
This section describes the fitting of the connecting duct, fan
unit, wall box and convection box.
1. Remove the convection box from the wall box by
removing the 2 screws in the fire back (Fig. 7).
2. Position the wall box on the non-combustible base
and slide into the opening in the inner wall. Mark
through the fixing holes onto the base then drill and
insert the plastic plugs supplied. If securing to the
base is not suitable, drill 4 holes around the flange
into the surround, and insert plastic plugs.
3. Push the connecting duct through the cut-out in the wall box and the hole in the wall
and temporarily secure the mounting plate to the wall box. Take care not to damage
the gasket.
4. Go outside and mark the connecting duct in line with the outside face of the wall.
5. Go inside and remove the wall box once again, take off the connecting duct and cut off
85mm inside the marked line.
