1. Why am I required to purchase a surround with the fireplace at additional cost?

Without a surround, you would not be able to complete your fireplace installation, the surrounds finish the fireplace so you can't see the wires and controls. These items are an additional cost due to the wide range of prices for the different options.

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 log and stone kits are optional accessories designed to enhance the look of your fireplace. You can find them and other media kits on the accessories page.

4. How is the fireplace vented?

The LHD45 is typically vented using Napoleon's 4x7 venting components, you can find them here. For a simple venting installation on an exterior wall, you can use the 4x7 Top Vent Kit. 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.


Questions & Answers

Ask a Question
  • Can a blower be used with the linear fireplaces or are those only compatible with standard ones?
