Method B - Securing with wire.
This method of securing is recommended where the wall / brickwork is in poor
condition or where marble back panels / surrounds are used.
Although this section deals with fireplace openings without a spacer, this method of
securing the heater it can also be used with the optional spacer frame (See method
C).
1. The fixing kit supplied with the heater
includes a wire and eyescrew. These can be
used to secure the heater to the back of a
surround / fireplace opening.
2. Mark the eyescrew position on the centre
line at the back of the fireplace opening and at
a height of 565-575mm (See figure 8).

8. CLEANING AND MAINTAINING THE HEATER
Important Safety.
Before undertaking maintenance always disconnect the heater from the electricity
supply by removing the 3 pin plug and allowing the heater to cool.
How do I Clean my heater?
The heater and plastic parts need only to be wiped clean with a dry soft cloth; do not
use polishes or abrasive materials. This is especially important when cleaning the
effects screen.
I have a problem with my heater!
1. My remote control does not work.
The batteries in the remote control handset probably need replacing - See section 4
and figure 4. The heater can be operated manually as on page 17.
2. My heater is switched on but there is no effect or heat.
The first thing to do is check the wall socket. To do this plug in a known working
appliance. If the appliance you have plugged in works then there is a good chance
that the problem lies with the 13 Amp fuse in the heater plug. If either fuse or socket
is suspected, have them checked by an electrician.
3. My heater is on, I have selected a heat setting but there is no heat, just the
effect.
A cut out device is fitted to the heater to prevent damage due to over heating. If it
operates due to an obstruction in the airflow, the heater must be turned off and
allowed to cool for 15 minutes and the obstruction removed before restarting.
INSTALLER AND OWNER GUIDE

4. I have dark areas in the fuel effect of my heater or the fuel effect is not as
bright as it was when new.
There is a mirror fitted to the rear of the hood / canopy at
the front of the heater and this may need cleaning. Wipe
the mirror with a clean, dry, non abrasive cloth (See
figure 19).
5. I have a problem that is different to those in the
previous examples 1- 4.
