2C. Indoor Installation
The Laars Lite 2 Model LC (Australia) heater is
design-certified for indoor installation only when
equipped with a draft hood. Check the rating plate or
the parts list (Section 6) for the correct Laars draft
hood part numbers. Install the draft hood without
modification.
Connect the draft hood to a vent pipe which stops
at least 0.6 m above the highest point of the roof or
other object that is within 3 m of the flue. Install a
listed cap which allows a full equivalent opening for
flue products (see Fig. 3).
