Installing the Exhaust System
3.1 Before You Begin
For efficient and safe operation of the Oasis
®
SCH33™ follow all
recommendations for properly installing the exhaust. Any
deviations from these recommendations must be approved in
advance by ITR.
Although the heater’s exhaust produces very low carbon
monoxide emissions, caution is advised:
• Do not operate the Oasis SCH33 in an enclosed area unless
there is adequate ventilation.
• This is a direct vent system. The Oasis® SCH33™ HW must
be installed in a compartment that is isolated from the
living space. The combustion air must be drawn directly
from the outside, without coming in contact with air that
can infiltrate the living space. See section 3.4.
• Heater exhaust can reach high temperatures; never install
exhaust parts close to combustible materials or through a
combustible wall or ceiling without fireproof protection.
Heater exhaust must be directed to the outside of the
vehicle away from windows, inlet vents, and slide-outs. The
heater exhaust system must be installed following all
specific RVIA standards.
