Balanced Flue
LASERTM Heaters are supplied with a flue and all flue parts for a typical "through the wall"
installation for walls between 230mm and 330mm thick (for thicker walls see flue extension kits
on the accessories page).
The balanced flue assembly is made as a "tube within a tube" (see photo on right - click photo to enlarge) that installs through an outside
wall. The heater exhaust fan "power exhausts" combusted gasses from the heater to outside via
the inner 42mm diameter stainless steel tube and the combustion air fan "sucks" outside air
through the 60mm diameter "green outer tube" into the heater.
Simple "Through Wall" Installation
To install the balanced flue assembly in its most simple manner -- create a 75mm diameter hole in the outside wall with a
slight downwards angle falling toward the outside as condensation (a few drops per minute at
worst) forms in the hot exhaust tube and must be directed outside. Disassemble the balanced
flue by unscrewing part A from part B (see photo on right - click photo to enlarge).
The balanced flue becomes two seperate parts when disassembled (see photo on right - click photo to enlarge).
Fit part B into the wall from inside, and part A into the wall from outside. Then screw
the two parts together until the wall is firmly clamped between the flanges effectively
eliminating holes through roofs, flashing, weather cowls etc. The installation is now complete.
The balanced flue is suitable for "zero clearance" in a "combustible" wall, and must be used in
every LASERTM heater installation where the flue passes through the building wall because the
heat exchange effect in the cooling of the exhaust pipe temperature and preheating combustion
air are vital parts of the overall performance of the LASERTM heater.
