Manual Operation; Remote Operation - Dimplex SP420 Installation And Operating Instructions Manual

This section provides step by step instructions for selecting a
location and preparing the site to install the fireplace into the
following:
Existing Fireplace
1. Make sure that the fire is located on a flat surface.
2. Seal all draughts and vents to prevent chimney debris
from falling onto the Fireplace Insert. Do not install into an
existing fireplace that is prone to dampness.
3. Remove the fire front panel by following the steps as
outlined in 'Lamp Replacement' sections and Fig.10 for SP4
and Fig. 12 for SP9.
4. Locate the 4 fixing holes, position the fire accordingly,
and firmly fix the appliance to the wall using the appropriate
screws - see Fig. 5a.
5. Replace the front panel.
New Support Structure Construction
When planning where to position your purpose built support
structure the following steps must be observed:
1. Place the fire in the desired location to see how it will
look in the room.
2. Mark the desired location for the new support structure
in the room and store the fire in a safe, dry and dust free
location.
3. Using timber studs to support the fire, devise and
construct a suitable means of supporting the product within
the wall partition and provide electrical power for the fire to
be HARD wired. For recommended sizes of height, width
and depth of opening for recess and hole fixing dimensions
for each model - see Table 1 and Fig. 5a.
4. When the structure is complete, remove the front panel
of the fire by following the steps as outlined in 'Lamp
Replacement' sections and Fig.10 for SP4 and Fig. 12 for
SP9.
5. Locate the 4 fixing holes, position the fire accordingly,
and firmly fix using the appropriate screws.
6. Replace the front panel.

The Standby Switch (Switch S1) must be first turned 'ON' and
the AUTO/MAN (Switch S2) switch set to 'MANUAL' to operate
the manual controls - see Fig 6.
Note : When the fire is put in Manual mode the first time the
flame effect will come on indicated by the Bottom neon coming
on for 3 seconds - see Fig 7.

Remote Operation

The standby switch (S1) must first be turned 'ON' and the
'AUTO/MAN' Switch turned to 'AUTO'.
Note: It takes some time for the receiver to respond to the

Pressing the ' O ' button on the remote turns off the light &
heat settings. To resume press the ' I ' button until the desired
setting is reached - see Fig. 8.
To increase or decrease the brightness of the flames, use the
dimmer button (Switch S4 on the fire or the
Remote Control). You can have any setting between full
brightness and the flames totally off. The heat setting will
remain the same.
To turn off the power the Standby Switch (Switch S1) must be
turned 'OFF'.
Note : Every time that manual mode is selected the previous
light and heat settings come on automatically.
Replacing the remote control
The new remote control must be set up as follows:
Press switch S1 to ON.
Press switch S2 to AUTO (see Fig. 6).
Press switch S3 to O for more than 3 seconds until the LED's
are on (see Fig 7).
Press the ' I ' button on the remote control.
Now the heater has learned the serial number from the remote
control and will work with this remote control only (this
procedure is repeatable many times).
