Chimney Installation
A chimney performs two functions: it removes smoke and flue gases from the heating system, and it provides
“draft” for the fire. Draft is the term used to describe the suction that occurs when hot air rises and creates a
vacuum in the firebox. That vacuum draws fresh air into the firebox and feeds combustion of the wood. No
heating system can operate properly without adequate draft.
Proper installation of the chimney flue is critical to the performance of your KOZLUSAN Heating System.
The majority of problems encountered after installation are attributable to a flue that is improperly sized or
otherwise provides inadequate draft to the heating system.
You may connect the KOZLUSAN Heating System to an existing flue or chimney subject to the following
conditions.
1. A qualified professional has inspected, repaired (if necessary), thoroughly cleaned the chimney and
determined it is suitable for use with a residential heating appliance that burns solid fuel.
2. The chimney or flue should be at least 3-4 m tall and sized correctly for the KOZLUSAN Heating
System model installed.
3. Do not share a flue with another heating system, appliance or fireplace. Do not use a flue that already
provides make-up air to the cellar or basement.
4. Tightly close the cleanout opening in the base of the chimney.

The heating system is leak-tested at the factory during final assembly, and the heat transfer fluid drained for
shipment. The recommended solution is a mix of 30% propylene glycol to 70% water unless you are located
in a very cold climate, or you plan to leave the heating system unused for a long period of time. A 30%
solution of propylene glycol is adequate to lower the freezing point to -13º C and raise the boiling point to
102º C.
CAUTION: DO NOT use ethylene glycol-based (automotive antifreeze) coolant in your
Kozlusan Heating system or in your home’s heating system. Always use propylene
glycol -based coolants.
