The finishing detail, thoughtfully chosen.
Replace the visual character of the documented legacy Optimyst installation with a river-rock presentation. The media is a separate finishing choice; it does not supply a cassette, firebox or flame system.
Dimplex’s legacy accessory table specifies one kit for CDFI500, two for GBF1000 and three for GBF1500. These are kit-ordering quantities for those named arrangements, rather than a stone count inside each retail kit.
Match the complete generation and model before ordering. Compatibility with the current RGB cassette is not established by this legacy listing.
The right fit starts with the exact model.

Let’s get your project right.
How many kits should I order?
The manufacturer’s legacy table specifies one kit for CDFI500, two for GBF1000 and three for GBF1500. Match that complete appliance code first; a nominal fireplace width alone does not establish the quantity.
Will it fit the current Optimyst RGB cassette?
The source lists legacy CDFI500 and GBF applications. It does not establish current CDFI500-PRO-RGB compatibility. Do not select this kit for an RGB cassette solely because both products use the Optimyst name.
Does one retail kit finish a GBF1000 installation?
The legacy GBF1000 arrangement is listed with two kits. One retail kit is therefore not the complete listed media quantity for that arrangement.
Can I use it without an Optimyst cassette?
This is decorative media for the named Optimyst arrangements. It does not create a flame effect or include the water-based cassette system.
Does the kit change the heater performance?
The accessory listing does not establish a different heating output. The installed appliance and any separately specified heater determine the heating configuration.
Is the kit a replacement for the cassette’s water supply?
No. Media selection and the appliance’s water arrangements are separate. Retain the water, ventilation and service requirements in the exact cassette installation guide.
Should I combine it with another decorative kit?
Use the media arrangement permitted by the exact appliance instructions. The quantity table does not establish that different log, rock or ember kits can be mixed together.
Can I order by the number of individual stones?
The available manufacturer evidence specifies retail kits per named installation, not an individual stone count or a guaranteed stone size. Order by the kit code and documented application.
Is GBF1000 the same as the current RGB Pro Box?
Do not treat those names as interchangeable fit evidence. This kit’s documented legacy GBF application does not authorize a substitution into a current RGB assembly.
What information helps avoid the wrong order?
Use the complete cassette and firebox model, the current media arrangement and the CDFI500-RVRCK ordering code. That identifies the generation and the required number of retail kits.
CONFIDENCE BEYOND THE FIRST FIRE
The right fit. The right support.
Keep the exact accessory code, appliance model and purchase record together for replacement-part and fit support. This separate accessory does not automatically inherit the fireplace’s warranty period.
