1. Do I need to purchase a front with the fireplace?

No, the BL46 is designed as a clean face fireplace in includes the glass and the basic black safety screen (to prevent accidental burns). You can also add an optional surround in either classic black or stainless steel, the surrounds make finishing around the fireplace a little easier as they will cover any unfinished edges in the material around the fireplace opening. Use the drop down menu above to add a surround to your purchase.

2. How will the fireplace be delivered? Will the delivery driver bring it into my house?

All fireplaces are delivered via freight (tractor trailer truck) to the specified street address you provide us, we do provide free lift gate service with all freight deliveries. The delivery driver is only responsible for unloading the items from the truck, not to move them anywhere. For more information on the delivery process visit our FAQ page.

3. The picture shows logs and stones, are those included?

No, the logs and stones are optional accessories. You can find them on the BL46 Accessories Page.

4. How is the fireplace vented?

The BL46 is a top vent model and is typically vented using Napoleon 4x7 venting components, you can find them here. If you need help designing the venting system let us know with an email or a phone call and we can assemble a custom solution for your situation. Let's say your new fireplace is going on an exterior wall, you may be able to use the Top Vent Kit which includes 5 ft of flexible venting and a horizontal termination.

Questions & Answers

Ask a Question
  • I'm concerned that this model and its 24,000 max BTU's, wont produce enough heat for the great room we are looking to install it in. The room is 900 sq. ft.?

    This may be ok for your room but there are a few things to keep in mind. This unit is not intended to be a primary heat source. Also, whether this will heat the room to your desire depends on how well your walls and windows are insulated and you would also need to consider the height of your ceiling. Thanks for the question!

  • Why can't one use the birch log kit in this fireplace? I understand you can't, but trying to understand why?

    Any accessories approved for the fireplace have to be tested by the manufacturer.  If they haven't tested it for use with this model, then it's not approved for use.  Thanks for your question!


    The flame adjustment by remote is only possible if you include the full function remote control, EFCN or EFCP.  Thanks for your question!

  • Do we need to order a trim kit with this fireplace?

    No, you're not required to order a trim kit or surround with the BL46 as it can be installed as a clean face fireplace.  Without the surround you will need to keep in mind that the whatever type of finish material you use will need to have a finished edge as it will be exposed.  The optional surrounds cover the edge of the finish material making it a little easier to complete the installation as you don't need to worry about creating clean edges.  Of course, you can always purchase the fireplace now and the surround later on if you aren't sure if you want it.  Thanks for your question!
