Low, High or Vaulted Ceiling Installation Options
This ceiling fan can be installed on ceilings that are 8 or 9 feet high and can be angled up to 26 degrees without the need for any additional
mounting hardware, so what is in the box will be sufficient. If you have a high ceiling or vaulted ceiling that is angled more than 26 degrees (or both),
you may need a downrod or angled ceiling adapter in order to install your fan.
Minimum Ceiling Height Requirement: This fan requires a minimum ceiling height of at least 96" in order to meet building codes. If your ceiling is lower than 96" then you may need to add a flushmount adapter or close to ceiling dowrod if one is available for the fan (see below).
If you cannot find what you need to make this fan work in your room, please give us a call so we can check to see if there are any further alternatives.
How long of a downrod do I need?
Building codes require ceiling fans to be installed with the blades no lower than 7 feet from the floor in residential applications (industrial fans may require more distnace). The closer you are to the fan blades, the more cooling effect you will feel, so 7 feet is the optimal distance from the floor for most residential ceiling fans to get the most benefit.
Any light fixture you choose to add to this fan is allowed to be less than 7 feet from the floor, so just make sure you have enough headroom to walk under it if need be.
The downrod included with the Emerson Prima ceiling fan is 4.5", which puts the blades 12" from the ceiling. Here are the Minimum Ceiling Heights required for each downrod available for this fan. Each length will put the fan blades 7 feet from the floor, so if you want your fan blades higher than 7 feet, choose a shorter downrod to fit your needs.
- 2.5" Downrod for 7.83' ceilings (blades 10" from ceiling)
- 12" Downrod for 8.62' ceilings (blades 19.5" from ceiling)
- 18" Downrod for 9.12' ceilings (blades 25.5" from ceiling)
- 24" Downrod for 9.62' ceilings (blades 31.5" from ceiling)
- 36" Downrod for 10.62' ceilings (blades 43.5" from ceiling)
- 48" Downrod for 11.62' ceilings (blades 55.5" from ceiling)
- 60" Downrod for 12.62' ceilings (blades 67.5" from ceiling)

About Angled Ceilings
This fan will hange from flat ceilings and ceilings angled up to 26 degrees using the hardware that comes in the box. If your ceiling is over 26 degrees, you can by an Angled Ceiling Adapter that will allow you to install the fan on a ceiling angled up to 45.
How to measure Rise:
Rise is the vertical distance your ceiling rises for every horizontal foot. Rise per foot is called Pitch. A roof with a 4/12 pitch rises 4 inches vertically for every 12 inches horizontal.
Our calculator uses roof pitch to calculate the angle of your ceiling. Since we already know the horizontal measurement is 12", we only need you to enter in the vertical rise to make the calculation.
To measure the rise of your ceiling: Hold a 12" ruler ruler horizontally (using a level) with one corner touching the ceiling. Then take measure the vertical distance from the other end of the ruler to the ceiling. This is the rise. Select your dimensions in the form above to calculate the angle of your ceiling. Most ceiling fans (except for hugger fans) can hang on ceilings angled up to 30 degrees without
the need for an angled ceiling adapter. 30 degrees is slightly less than a 7/12 pitch. Most angled ceiling adapters will allow your fan to hang up to 45 degress...which is a 12/12 pitch.

Emerson Prima Ceiling Fan Comparison Review
How does the Emerson Prima Compare to the Average Ceiling Fan?
Quality Rating = 4 (average is 3)
A Quality Rating of 4 is above average, the Emerson Prima ceiling fan will run smooth and quiet and will give you many years of operation with no worries of the motor burning out.
Airflow = 5263 CFM (average is about 5755)
5263 CFM is pretty much average, so don't expect a super strong breeze from this fan. However, most people
are used to average ceiling fans, so if you have never experienced a fan more powerful than this, you may be satisfied with the Emerson Prima.
Efficiency Rating = 89 CFM/Watt (average is about 86)
An Efficiency Rating of 89 is
fairly average.
Efficiency is defined by the EPA as the amount of airflow a fan produces (CFM) divided by the amount of
electricity (Watts) it uses on high speed without any lights on. Efficiency is less important than Airflow because more
CFMs allow you to raise your thermostat higher...which is where you will save the most energy. Efficiency becomes more important if
you expect to operate several ceiling fans at the same time. (see calculator below)
Electrical Usage = 59 Watts (average is about 76)
59 Watts per hour is
well below average, which is excellent because the Emerson Prima will cost less to operate than the average ceiling fan.
Use the calculator below to estimate just how much it will cost to operate this fan in "Your home".
CFM -vs- Efficiency: CFM is KING! It is more important to buy a fan with higher CFMs than it is to buy a fan that uses less electricity. The highest wattage consumed by the most energy guzzling ceiling fan on our website is about 120 watts. So if you input 120 as the fan watts and run our calculator, you will see that it still costs less than 2 cents per hour to operate the most energy guzzling ceiling fan in most states.
You will get more savings with a higher CFM fan than a lower Wattage fan because if your fan moves more air
you will be able to raise your thermostat to a higher degree. Raising your thermostat by 10 degrees can save you up to 40% on your cooling bills. Choosing a less powerful fan because it uses less electricity can be the worst mistake you can make because it will not cool you off enough to allow you to raise your thermostat to a high enough level without becoming uncomfortable. This is why CFM is so much more important to consider than Wattage.
Emerson Prima Operational Cost Calculator
How to use our Ceiling Fan Cost Calculator
Basic Help: Our cost usage calculator shows you how much it will cost to operate the Emerson Prima ceiling fan. By default, the calculator assumes that you will leave your fan running 24 hours a day for the entire year (which is not very likely to be accurate), so you will want to change the hours and days to be more in line with how often you think you will use the fan. The calculator also defaults to the average cost per kWh of electricity in the USA. You can change this to use the average cost of electricity in your state, although this may vary widely from city to city. For the most accurate calculation, manually enter the actual cost/kWh shown on your utility bill.
The wattage of the fan is already included (if it is known), but you can change it if you wish to see how the wattage affects the cost.
Fans with lights: Calculations are performed without lights by default. If you add a light fixture to the fan, you can add the wattage of the fixture to the wattage of the fan to perform calculations with the lights on. In some cases, when a light fixture of known wattage is included with the fan, the option to calculate with or without lights will show automatically. The light fixture on a ceiling fan almost always uses substantially more electricity than the fan motor, so it is very important to take that into account when comparing the overall operational cost between various ceiling fans
The average kWh by state used by our calculator is derived from information published by the
US Government Department of Energy as of May 2009.
Your actual cost may differ from this. Again, refer to your utility bill for your most recent kWh cost.
