The finishing detail, thoughtfully chosen.

Dimplex Optimyst Pro Box Front Glass Pane

FG1000 completes the front-glass selection for the documented legacy Optimyst Pro Box arrangement. Select it by its exact accessory code rather than a general 40-inch description.

Dimplex lists the accessory at 40⅝ inches wide, 14½ inches high and 1⅝ inches deep. These are the accessory dimensions; they do not describe the fireplace framing opening.

The front glass is separate from a rear-glass pane and from the cassette system. Keep the enclosure, cassette and glass selections distinct when reviewing the complete installation.

The right fit starts with the exact model.

Let’s get your project right.

Is FG1000 a rear-glass panel?

No. FG1000 is the front-glass accessory. GBF1000-GLASS is a different ordering code for a rear-glass application; similar model numbers do not make the two panes interchangeable.

What are the glass accessory measurements?

The manufacturer catalog lists FG1000 at 40⅝ inches wide, 14½ inches high and 1⅝ inches deep. These measurements describe the accessory, not a rough opening.

Can I use those dimensions to frame the fireplace?

No. Follow the exact firebox installation guide for the framed opening, clearances and support. The glass dimensions alone do not establish those construction requirements.

Does the CDFI-BX1000 firebox include this glass?

The exact enclosure listing identifies FG1000 as separate. Review the package you are ordering so the front glass is accounted for without assuming it comes with a firebox-only enclosure.

Does this glass include an Optimyst cassette?

No. This listing is the front-glass accessory. The enclosure and the required flame-system components are separate parts of the complete installation.

Will it fit a current RGB Pro Box?

The accepted evidence establishes the legacy FG1000 application. It does not establish interchangeability with current RGB Pro Box glass. Match the exact installation guide and ordering code.

Is the carton size the finished glass size?

No. Shipping dimensions include protective packaging. Use the accessory measurements shown here for the glass and the compatible firebox guide for installation.

Can I use a similarly sized glass panel instead?

A similar width does not establish the mounting arrangement or suitability for the appliance. Use the exact accessory specified for the complete firebox model.

Does front glass replace the firebox ventilation provisions?

No. Keep the ventilation and access arrangements required by the firebox and cassette instructions. An accessory pane does not redefine the complete installation requirements.

What should I check before replacing an existing pane?

Record the complete firebox model and the original glass code. Confirm that the required part is the front assembly, rather than the rear pane or another trim component.

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.

Where we ship

We ship within the United States, excluding Alaska and Hawaii.

Free Shipping on All Orders

Shipping is free on all orders.

Shipping and delivery timing

Most products ship within 24 hours of ordering, unless a different lead time is shown for the product. Delivery takes 2–4 days after shipment.

Tracking your order

Look for your shipping confirmation email for tracking information when your order ships. Items may arrive in separate shipments. Carrier delivery dates are estimates; contact us if you need help checking your order’s status.

Curbside delivery

Large or heavy products may arrive by freight. Standard freight delivery is curbside: plan for help moving the shipment from the curb to its final location. Carry-in service, assembly, installation and packaging removal are not part of standard curbside delivery.

Keep your delivery phone number current and watch for carrier instructions. Some carriers arrange an appointment; others provide an estimated delivery date. Let us know about stairs, narrow roads, gated access or other delivery restrictions before ordering, and confirm any liftgate or additional service needs with us.

Review the shipping information shown at checkout. For delivery timing, destination questions or special arrangements, call or email before placing your order.

Hassle Free Returns

Return requests must be made within 7 days of receiving your order. Call or email us with your order number and the item you would like to return.

You must contact us in advance to arrange return pickup. Please do not send items back without first arranging the return with us.

There is no restocking fee. For change-of-mind returns, customers are responsible for return shipping costs, which will be deducted from the refund. Customers do not pay return shipping for damaged items.

Keep the original packaging and all parts and accessories. If you’re considering a return, leave the product unused and uninstalled while we review your request. Custom-made items are identified on the product page before adding to cart and before order confirmation. Custom items cannot be returned for change of mind. Damaged-item support still applies.

Order cancellations

Custom orders may be canceled within 48 hours of order placement, provided production has not begun. Once a custom item has gone into production, it cannot be canceled.

Non-custom orders may be canceled within 4 hours of order placement. After this period, we will do our best to accommodate a cancellation request, but cancellation cannot be guaranteed.

Call or email us with your order number to request a cancellation.

Refunds

Approved refunds are issued immediately upon inspection of the returned item, to the original method of payment used for your order. Once we issue your refund, it usually takes 7–10 days for the credit to appear in your account. The exact timing depends on your credit card issuer, bank or payment provider and their processing policies.

This timeframe begins when the refund is issued, rather than when a return is requested or shipped. For change-of-mind returns, return shipping costs will be deducted from your refund. Customers do not pay return shipping for damaged items. There is no restocking fee.

If your refund has not appeared after 10 days, check your account or card statement and contact your bank or payment provider. If you still need help, contact us with your order number so we can help check the status.
