King Electrical Floor Heating Mat Installation Manual 8
2.5 Border allowance: Heating cable should be installed between 1” and 6” from the perimeter walls, but not more than 1.5”
from a kick space vanity, shower, bathtub, counter or doorway. It is not necessary to heat the floor all the way to the wall as it is not
typical that people will stand that close to the walls. In addition, the heat will radiate out an additional 2” from where the cable is
embedded.
2.6 In most cases simply select the mat kit that is 5% but no more than 10% less that the total square footage of the area to
be heated as calculated in the previous step. For example: if the square footage after deduction the fixed obstacles equals 74 ft ,
then the closest cable kit is 70 ft which is 5.4% less allowing for an unheated border. The next size down is 60 ft which is too
small and would not be enough cable to properly heat the room.
2.7 Select either 120 or 240 volt cable depending on the power supply available. DO NOT mix voltages on the same system
when more than one cable is used to cover a room .
