Ensure that there are no gas or water lines, or 
electrical circuits in the wall location where the flue 
hole is to be drilled.   
Drill the flue hole using a 3 1/8 inch (80 mm) drill.  
The center of the hole  must be located anywhere 
within the shaded area, unless extension kits are 
used.   See diagram.   
For weatherboard walls, drill through the center of 
the weatherboard from the outside first and then 
through the plasterboard.  A template is provided.   
For installation without using extension kits, the 
configuration of the flue manifold, air intake hose, 
and exhaust slide pipe should be as shown when 
installation is completed.  The shaded area shows 
where the flue manifold can be located.
