The current models of the Guardian Series automatic standby generators feature a one hour fire rated enclosure, and are in compliance with NFPA 37 Article 4.1.4 Condition 2 for clearance from combustible construction. This means that the back side of the generator can be installed a minimum of 18” from a surface. The intake and exhaust, which are the short ends of the generator, and the front side of the generator require a minimum clearance of 36” from a wall. However, the distance required from the unit to any window, vent, door, opening into the home, an overhang, and trees, plants or shrubs over 12” in height is a minimum of 60”. Further information on proper installation can be found in the installation guidelines. A copy of the installation guidelines can be located by searching the model or serial number for the generator here: http://www.generac.com/Service/Manu...
Please note that prior models or other series units may not meet these exceptions. Utilizing the unit’s model or serial number to locate the owner’s manual or installation guidelines will ensure that the correct distances are followed.
We recommend contacting your local inspector, as state and local codes may vary, and will supersede manufacturer recommendations for installation near a structure.
