·
The exhaust fitting on the Oasis
®
Chinook Heating System is
2.0” O.D. and the exhaust pipe used must have a minimum of
2.0” I.D. throughout its length.
·
All exhaust elbows must be of a large radius design.
·
The exhaust run must be supported a minimum of every 3’ of
its installed length.
·
The exhaust and Oasis
®
Chinook Heating System connection
point must use appropriate clamps and sealing compound to
ensure that the connections are tight and leak free. Make
sure any sealing used does not restrict the exhaust flow. The
Oasis
®
Chinook Heating System exhaust outlet pipe and the
exhaust pipe itself must not be distorted or damaged during
this process.
·
When the Oasis
®
Chinook-S Heating System is running the
connection points and the system must be checked for leaks
and any found must be corrected. Periodically, check the
exhaust fittings, connections, exhaust tube, and insulation for
leaks and integrity; make repairs or replacements if
necessary.
·
Appropriate exhaust insulation must be used to cover the
entire length of any interior exhaust run.
·
Solid stainless steel exhaust tubing or approved exhaust
tubing is recommended but an approved stainless steel
flexible exhaust tubing can also be used. If flexible exhaust
tubing is used, the exhaust tubing must be inspected
regularly for leaks and deterioration as this type of exhaust
does not have the life expectancy of solid tubing. U-bolt
clamps are recommended for joining flex and solid tubing as
they apply firm, even pressure.
·
Install an exhaust collar on the exhaust pipe to isolate the
pipe from the coach frame. This reduces vibration and noise
and protects the coach from the effects of high exhaust
temperature. If an ITR exhaust collar (5") is used, be sure to
position the Chinook so the exhaust is centered in the
exhaust collar. If an ITR exhaust collar is not used, be sure
that the temperature rise of any combustible material
surrounding the exhaust does not exceed 50°C (90°F), when
the heater has been running continuously for 1 hour. See
Figure 3-1: Installing the Exhaust system (Bottom Exhaust).
