1. Why am I required to purchase burner and log set with the firebox at additional cost?

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

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

All fireboxes 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 firebox?

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

4. How is the firebox vented?

This firebox is vent free and does not require any venting. Be sure to check your local codes as vent free appliances are not allowed in all states.
