2.2. Field Assembly
The Lite2 heater is shipped from the factory with
the top assembly in the low-profile configuration for
outdoor installation in the U.S. In Canada, an outdoor
installation requires the addition of a factory approved
vent cap. The Lite2 heater is design certified for
indoor installation when equipped with a draft hood,
which must be installed without modification.
The Lite2 heater is also certified for installation in
an outdoor shelter in Canada when equipped with a
draft hood. An outdoor shelter is an enclosure not
normally occupied which does not communicate
directly with occupied areas.
