Section 3, Installing the Exhaust System
International Thermal Research
·
The exhaust must have a minimum of 3" (7.6 cm) clearance
from all surfaces.
·
Ensure that the exhaust cannot be plugged or restricted.
·
If it is required that part of the exhaust is run through the
interior of the vehicle, appropriate exhaust insulation must be
used to cover the entire length of the interior exhaust run.
·
The exhaust parts supplied with the Oasis® Zephyr™ HW
include: a 3" x 1.25" MPT black-iron pipe nipple (part# 2342)
that is threaded into the exhaust outlet on the bottom of the
heater, a 1.25" FPT black-iron pipe elbow (part#2337) which
is threaded onto the nipple and a 1.25 MPT x 1.5 OD pipe
adapter. The adapter is threaded into the elbow and used to
couple with flared 1.5 OD exhaust pipe or stainless flexible
exhaust tube. If the optional muffler (part#10282) is used,
the adapter is not used and the MPT end of the muffler
screws directly into the elbow. Any exhaust fittings/pipe used
to extend
·
the assembly of supplied parts, must have a minimum of
1.25" ID.
·
Solid steel exhaust tubing or other approved exhaust tubing
is recommended. Stepped, bolt-style band clamps are
recommended for joining the tubing as they apply firm, even
pressure.
·
The exhaust must be supported at least every 3' of its
installed length.

compound, as it can clog the exhaust. Any part of the
exhaust system that is damaged or deformed during the
installation process must be replaced. ITR does not provide
warranty coverage or claims resulting from an improperly
installed heater exhaust system.
·
When the heater is running, the connection points and the
system must be checked for leaks. Do not operate the heater
if there are any leaks in the exhaust system. Periodically,
check exhaust fittings, clamp connections, exhaust tube/pipe,
for leaks and integrity, also check the integrity of exhaust
insulation if installed.
