<div dir="ltr">All - update for those of you interested, we are starting the portal installation tomorrow (with a Sunny Island for better or worse) and ended up going with a Kohler 14RESA propane generator. This should be 2-wire start, ok at 100% duty cycle 120 v, and CARB compliant. If all goes as planned we'll be up and running next week and I'll keep you posted.<div><br></div><div><a href="http://www.kohlergenerators.com/home-generators/products/14RESA">http://www.kohlergenerators.com/home-generators/products/14RESA</a><br></div><div><br></div><div>-August</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><p><b><span style="font-size:9.0pt;font-family:"Century Gothic","sans-serif"">August Goers</span></b></p><p><span style="font-size:8.0pt;font-family:"Century Gothic","sans-serif"">Luminalt Energy Corporation</span></p><p><span style="font-size:8.0pt;font-family:"Century Gothic","sans-serif"">o: 415.641.4000</span></p><p><span style="font-size:8.0pt;font-family:"Century Gothic","sans-serif"">m: 415.559.1525</span></p>
