Maintenance
11.1 The First Few Weeks
Once the Oasis
®
SCH33™ heater has been installed to approved
standards and workmanship, and you have test operated it a few
times, the system will require little maintenance.
About two weeks after your Oasis SCH33 heater has been
running, you should conduct a general inspection of the entire
system.
Check for any leaks in the exhaust, fuel, or water systems.
Tighten all clamps.
It is strongly recommended that the Oasis SCH33 heater
be started and allowed to run through one complete
heating cycle at least every 30 to 45 days to ensure its
proper function and to verify the proper operation of all
components.
11.2 Adding Heat Transfer Fluid
(Antifreeze)
The Hurricane SCH33 Heating System must use a non-toxic,
propylene glycol-based heat transfer fluid (coolant) with
additives generally recognized as safe” GRAS” by the FDA.
Use of non-propylene glycol-based heat transfer fluid can be
harmful if contamination of potable water occurs due to a
leak in a heat exchanger, which can be caused if the fresh
water in the system is allowed to freeze.
Normal Boiler antifreeze (heat transfer fluid) is a 50/50 mixture
of distilled water and propylene Glycol (nontoxic antifreeze)
There are several manufactures of pre-mixed heat transfer fluid.
It is important that fluids are not mixed in the Hurricane SCH33.
Mixing heat transfer fluids can alter the chemical make-up and
consistency of both fluids. Always use heat transfer fluid supplied
by the same manufacture to top-up the system.
