Product review (2 stars): Look good but problematic. Cheap and free shipping. Customer service is none.
Nice looking but has faulty features. After ran the blower for thirty minutes, unit shut down by itself, the LCD turns itself on/off, all lights are flashing blowers won't run. I have place calls and email to GV website but no return call. Since already paid for professional installation, I amp as not willing to take it down and ship it back, so I started troubleshooting it myself. It seems to me something is shorted inside the board. After an hour verify all components, i found out the timer is faulty or shorted. Disconnect the timer wire, issue resolved. Now it works without timer but It still better than RMA the unit and pay double installation cost. After all, unit looks great, blower is powerful with reasonable noise figure, LED lights are great addition. Don't use the gas sensor ( not sure if it works). GV customer service mad website is very disappointed.
