Note:

Indoor or well protected areas may need less coverage. Extremely cold or windy conditions may need

additional coverage. For example, if you are trying to heat a 3m x 3.5m area which is very cold, an ALF30
model heater may not be sufficient. Instead, you may need to install the more powerful ALF40 heater
model. It is recommended that you contact the supplier if you are unsure of your requirements.

The following diagrams show the main dimensions of the product.
