1. Why am I required to purchase log set and interior panel with the fireplace at additional cost?

The fireplace is designed for use with both of these items. Without them, your fireplace would not function correctly and would look incomplete. These items are an additional cost to allow you to choose which look you like best.

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. Where are the accessories for this fireplace?

You can find all of the available options on the accessories page.

4. How is the fireplace vented?

The Altitude X36 is typically vented using Napoleon's 5x8" flex venting or with an adapter, DuraVent 5x8 rigid venting. 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.
