FAQs
What size opening do I need to frame for the Altitude X 36?
Frame a minimum rough opening of 35-3/4" wide by 43-5/8" high by 19" deep. Always confirm against the installation manual for your specific model and venting configuration before cutting, and never let framing or finishing material encroach inside the fireplace’s finishing flange.
Can the Napoleon Altitude X Series 36" be controlled without the eFIRE app?
Yes. The fireplace includes a ProFlame II remote for everyday operation. The eFIRE controller is also included, and the app is an additional convenience for control from a mobile device, not a requirement.
What is the gas input of this model?
The AX36-2 has a maximum input of 36,500 BTU/hr on natural gas or 34,000 BTU/hr on propane. It is certified as a vented decorative gas appliance.
What does the optional heat management system do?
The optional Dynamic Heat Control (DHC) or Ducted Heat Management (DHM) system reduces the required clearances to mantels and wall-mounted televisions, giving more flexibility in how the fireplace is positioned relative to surrounding materials and electronics.
