2C. Outdoor Installation
Install the Laars XL-3 heater in the open, or in an
enclosure without a roof. The chimney cap supplied
with the heater must be installed. The danger of fire
requires a minimum clearance from combustible
surfaces or shrubbery of 6 inches (15cm) (see Fig. 6).
The flue products must be dispersed in the outside air,
and fresh air available for proper combustion. Do not
install the heater under eaves where roof drainage
could fall directly on the heater.
It is possible that prevailing winds could cause a
downdraft. Therefore, keep the side of the heater at
least 3 feet (91 cm) from the face of any wall or fence.
