Mfg Warranty says that I must get the warranty signed by the installer

I purchased a Home Depot extended warranty for my solar fan. do I still have to get in touch with installer and have them sign and date or does my Home Depot extended warranty solve this problem?

500 CFM Solar Powered Roof Mount Exhaust Fan is rated 3.8 out of 5 by 17.
Rated 5 out of 5 by from great product thiis was easy to install and looks great, and will fix our roof problems

Rated 5 out of 5 by from Works very well and is quiet Puchased this solar fan at Home Depot for $221 and my roofer charged me $100 to install it at the same time they were re-roofing my house. The fan works very well and is extremely quiet. I was surprised at how well it moved out the air in the attic. This fan does not have a thermostat so it will work in both summer and winter which is a good thing as you need air circulation in your attic in winter as well as summer. Make sure you aim the solar panel to the south or southwest as much as possible and this is also noted in the instruction manual. It will work facing east or west but South works best year round especially in winter. I live in Michigan

Rated 1 out of 5 by from Solar power fan This fan may work for a very small attic. but don't get your hopes up. I put it up and in the direct sunlight the fan was spinning fast but it did not move very much hot air out of the attic. My attic tempreture only dropped about 10 degrees durring the hottest part of the day. I took it back and bought one of the less expensive powered attic vent fan and it dropped my attic tempreture around 30 to 40 degrees. My attic was getting around 170 to 185 degrees and now it stays around 120 to 130. I would reccomend one of the power ones way before I reccomend the solar fan.

Rated 5 out of 5 by from Solar Fan Depending on the size and volume of the attic, you may need more than one fan. My home is 2400 square feet with corresponding attic size and therefore required 2 such fans. Even at $400 for the both, I believe it was well worth the investment. The fan is quiet, unlike the powered fans, and requires NO electricity. I figure a 2 year payoff at my current utility rates for a home I will live in for the rest of my life makes it a comfortable solution.

Rated 4 out of 5 by from Worth the money I have vaulted ceiling in my living room and the builders didn't have access to the back three bedrooms so I could get into the attic without making a hatch inside the house. I installed the fan myself and noticed there wasn't any controls to turn the fan on and off. I purchased a separate thermostat that hangs into the attic area and it turns the fan on and off as needed. Where I needed to install the fan was also shaded most of the day by a tree so it was nice that the solar panel was removable and I moved it 60 feet from the fan and attached it to a tripod that I was using for my TV antenna. I also installed an on/off switch so I can turn it off during the winter months. The fan is quiet and I noticed the three back bedrooms cool off quicker and stay evenly cooled.

Rated 4 out of 5 by from Solved a ventilation problem We needed this fan to get rid of the asphalt odor in the house for a period of 4 months after having a new GAF roof installed. We have a hip roof with small ventilation holes around the perimeter. The house was built with 2 round vents near the peak - one on the East and one on the West. The installer put in 4 slant back vents. Two to replace those near the peak and lower down - 1 on the North and 1 on the South. I believe that this created an imbalance in the venting system so that the there was not enough exhaust for the intake. The roofer agreed to replace the West facing slant back vent with a solar attic fan, if I purchased one. I chose a single 500 CFM even though for my square footage, it was recommended that I have two. I decided that I only needed one because I had plenty of other vents and I didn't want all the cold air in the attic removed. More exhaust might have caused too much heated outside air to be pulled in during the summer. The 500 CFM size seems to be the perfect size. When the air conditioner kicks on, the period where the interior vents blow hot air into the house is much shorter. It is almost non-existent.
