INSTALLATION OF HEATER
Section II 2-1 Location of Heater
The Hardy heater is designed to set outside the building to be heated. The unit must be
located a minimum of 10 feet from the building. The unit should be installed upon a
concrete pad. There are two typical options that we recommend.
Option 1 has the unit installed on concrete pad with the rear of the water tank flush with
end of the pad. We recommend the pad to be 48” wide and 53” long minimum. If you add
extra length it will allow ample concrete in front of the heater for loading wood and
removing ashes. The space between the rear of the unit and the outside cover will allow a
4 inch water tight pipe or other means to insulate the plumbing and electrical lines to run
directly into the ground. The outside cover can be removed by lifting it off the water tank on
all four corners. This will allow you easy access for the connection of the plumbing and
electrical lines.
Please see the illustration below for details.
