ITR Hurricane Zephyr HW, Installation And Operating Manual

Page: 23 / 89

Section 3, Installing the Exhaust System
International Thermal Research 3-3
· The exhaust parts for the Hurricane® Zephyr™ HW should
include: stainless flared 1.5 OD exhaust elbows, pipe or
1.5`ID stainless flexible exhaust tube. A muffler is
recommended for exterior noise reduction.
· The exhaust must be supported at least every 3’ of its
installed length.
· All exhaust connection points must use appropriate clamps
and a small amount of sealing compound may be used in
conjunction with clamps to ensure that connections are tight
and leak free. Do not overuse sealing 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.
3.3 What NOT to DO
Don’t disregard the total number of 90° bends when calculating the
total allowable exhaust length (12’ total, excluding the 90°
bend exiting the heater)
Don’t use any mufflers not supplied or approved by ITR.
3.4 Installation Procedure
To install the exhaust system:
Refer to Figure 3-1: Hurricane Zephyr™ HW exhaust parts and
typical configuration
1Plan-out the best location for the exhaust run.
2Leave suitable air spacing to protect combustible materials. Use an exhaust
collar and/or metal shields where required.
3Securely screw the exhaust fittings to the Hurricane® Zephyr™ HW and align
them in the appropriate direction according to the planned run.
4Connect the exhaust piping in series with the muffler, using appropriately rated
sealant if necessary and proper clamps. If vibration isolation mounts are used,
they must be rated for high temperature. The exhaust must be supported at
least every 3’ of its installed length.
