Warning:
Owners and Operators that fly must recognize that there are inherent risks involved in this activity.
Therefore every precaution in maintenance and training must be taken to minimize these risks as it is
unlikely that they can be eliminated entirely. The cabin heaters listed herein are a critical component of
the aircraft. Any failure of the combustion heater may result in a delay in departure, dangerous drop in
cabin temperatures, smoke, fire or even more severe consequences that may result in injury or death.
Heaters are subject to wear based on conditions that may make the same unit life vary from airplane to
airplane and condition to condition. The majority of our heaters are used in personal or business airplanes
and rotorcraft that subject them to usage that ranges from every flight to seasonal flights with long
periods of inactivity.
Each heater certified must demonstrate an adequate margin of safety before it is considered as safe to
operate in an airplane or rotorcraft. Most heater installations are performed by the airframe man-
ufacturer and many systems and components are added to the heater assembly. Even when every pre-
caution is taken in the design and manufacture of a heater as well as the installation, maladies have and
will occur.
It is essential that the heater be properly operated per the airplane flight manual or pilots operating hand-
book and maintained according to recommended service procedures found herein and in the applicable
aircraft service or maintenance manual.
The heater must be observed closely in inspection and operation
to detect any potential problems before they have a chance to become serious. Any abnormal or unusual
operating reports should be investigated and repairs effected, as it may be a warning of impending failure.
The heater is relied on to provide a comfortable and safe environment for the pilot and passengers. It is
critical due to the fact that heat is supplied via fuel combustion and air flow which, if uncontained, may
result in smoke and fire aboard the aircraft. Without the continuous care and maintenance called for in
this Manual, the heater will degrade and become unreliable and unsafe. Owners, operators and
mechanics should read and understand this Manual. It contains the necessary information about your
new heater to assure safe and long lasting operation. Please be certain to give it your undivided attention.
Thank you for choosing a Hartzell Engine T
echnologies LLC Combustion Heater. Maintained properly, it
will give you safe and reliable service for many years to come.
Sincerely,
Hartzell Engine T
