How can I obtain permission to install portable natural gas heaters in my sidewalk café?
To obtain permission to install portable natural gas heaters in your licensed unenclosed sidewalk café, you need to receive approval from the Department of Buildings (DOB) to install both the heater and its accompanying hardware. In order to operate such heaters you must also receive an Open Flame permit for heaters from the Fire Department (FDNY), and restaurant staff must hold an FDNY Certificate of Fitness (#G-93), which allows them to be responsible for supervision of the heater.
