Love this heater! I'm a 57 year young woman and I put this together by myself, in about 40 minutes.  I took my time to make sure I followed the directions exactly.  The think that seemed like took the longest was the protective plastic coating on the panels for the hood.  You will need to use a phillips head screw driver to tighten some of the screws properly.  There is no assembly for the heating component.  I hooked up my propane tank and followed the instructions on the heater and the igniter worked perfectly.  It is heavy duty.  Puts out about a 15 foot radius of heat.  Perfect for our back patio/seating area.  We love sitting outside, and this allows us to enjoy the outdoors in Tennessee when it gets chilly in the evenings.
