11.

Pull each cable taut. Push the cable

retainers hard up against the back panel. The
end of the cable adjuster will pass into the
hole. Tighten the screws in the retainers so that
they clamp the cables in position. Apply
tension to the cables by turning the hexagonal
adjusters by hand (See figure 20).

12.

Inspect the installation of the hotbox

against the fireplace surround. If the hotbox is
aligned squarely and the sealing is satisfactory,
fully tighten the cable retainers.

13.

If the hotbox is not correctly aligned,

release the tension on the cables by slackening
the screws and turning the hexagonal adjusters
fully anticlockwise. The hotbox should then automatically realign itself. Pull each cable
taut again and push the cable retainers back against the back panel. Again, tighten the
screws in the retainers and apply tension to the cables by turning the hexagonal
adjusters clockwise as far as possible.

. 

Feed the free length of the cables into the gap between the inner and outer back

panels so that they are available to allow easy
removal and refitting of the appliance during
subsequent service calls. 

Do not cut off the free

lengths of cable. 

On precast flue installations feed

the cables into the small holes at the base of the
side panels. 

10.2 Sealing floor front - all installations.

Using the floor sealing tape supplied, seal the
bottom of the hotbox to the fireplace and hearth
floor (See figure 21).

Make sure that the whole length of the front
edge of the hotbox is fully sealed.
