Installation into a plasterboard ceiling
Figure 3
Note: Access to the ceiling void, other than the heater cut-out must be available for
installation for plumbing, electrical connection and maintenance.
1)
Cut a square hole 575mm x 575mm into the plasterboard and ensure that any obstructions
are a minimum of 210mm away from the heater.
2)
Ensure suitable means of support such as threaded rods or chains are used and fixed into
place directly above the chosen installation cut-out.
3)
Lift the heater through the cut-out into the void and securely attach the supports to the
heater.
4)
Lift the grille into the cut-out and adjust the heater so that they meet together.
5)
Drill four holes 3mm
(1/8”) holes (two in each side) and secure with the provided screws
(see figure 4). Once secured the grille can be open and closed by pushing against the
grille on the side with the closure (Once to open, Once again to close), care should be
taken not to bend the grille.
6)
Proceed to page 5 for plumbing and electrical connection.

Plumbing connection
Pipe connections to the heat exchanger should be made using 22mm pipe and fittings, Isolating
valves should be fitted to ensure the product is serviceable in the future. It is advisable to use
flexible hoses to reduce vibration (available as an accessory, see page 7). An air vent must also be
fitted to the system pipework above the highest point of the product.
Pipe entry should be made through the entry holes in the end of the heater (shown in fig 1).
Isolating/ Service valves may be installed within the heater casing, a removable panel in the side of
the heater allows valves to be adjusted however additional access to the void space must be
available (in a T-Bar ceiling an adjacent removable tile would suffice however in plasterboard celling
access would have to be considered before installation).
Figure 5
Electrical connection
Unscrew and remove the electrical panel, connect the fused spur to the terminal block in the unit
using suitable 3 core cable (see wiring diagram below).
