Section 2, Mounting the Heater Unit
International Thermal Research 2-3
Figure 2-1: Oasis SCH33 Dimensions
If the Oasis SCH33 is going to be mounted in the diesel engine
compartment, check for adequate ventilation. Make sure there
are no exhaust leaks and that all exhaust fittings are well-
fastened to the heater and the muffler. Any assembly parts that
may cause injury through accidental contact should be
protected. Isolate the unit in the closed compartment so that no
exhaust from the heater will infiltrate the living areas.
• Choose a sturdy surface in a location that won’t be unduly
affected by vibration and the jarring of rough roads.
• Mount the unit with the front panel facing out and accessible.
Facing out simplifies installation, maintenance and servicing.
There must be at least 12” of accessibility on top and left side
of the heater for removal of the access panels and servicing of
the internal components.
• Ensure that the exhaust tubing can be properly and safely
routed to the outside. The maximum exhaust run with 1 90-
degree bend is 12’. Any additional 90-degree bend will reduce
the allowable exhaust length by 2 feet.
