*Mounting heights are provided as a guideline. Actual conditions may dictate variations from the above data. Always maintain the published clearances to combustibles. Not for residential use.
Clearance to combustibles

*Heaters mounted on an angle between 0° and 45° must maintain clearances posted for 0° or 45°, whichever is greater. Clearances published in RH Series manual and on warning label supersede data shown on this page. Reference RH Series installation manual for complete information. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent materials are protected from degradation.
