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

There are three different types of burners for the HD81, the Glass burner and River Rock burner are generally special order and may take additional time for shipping. The panels are required to conceal the inner elements of the fireplace as well as reflect heat to the living space rather than into the fireplace. 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 glass and stones, are those included?

The glass 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 HD81 is typically vented using Napoleon's 8x10 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.
