Procedure for Performing Warranty Work
As a member of the Espar distribution organization you are trained in the installation, troubleshooting
and repair of Espar heaters and systems and you have all of the necessary tools required to properly
diagnose heater functions.
Technical publications such as Technical Descriptions, Troubleshooting Guides and Parts Manuals
are available by downloading directly from Espar’s website (www.espar.com). Technical circulars are
issued periodically from Espar’s Technical Department. It is important to refer to current publications
while working on a heater. Special tools and test equipment are available for some heaters (please
refer to the Tools and Equipment section). If you have any questions, please contact Espar’s
Technical Department.
Once you have examined the heater for system or installation problems, as set forth in the preceding
section, and have determined that warranty work must be performed, follow the technical publications
and use your training and experience to correct the cause of the problem.
IMPORTANT NOTE:
Always ensure that the root cause of the problem is corrected, rather than simply correcting
the symptom(s) of the problem. For example: if a heater has overheated several consecutive
times and has been locked out (F15), do not simply reset the heater with the diagnostic unit.
Locate the source of the overheat problem and correct it.
Any part replaced under warranty must be tested as per current heater manuals test procedures to
confirm that it is defective before it is claimed. Parts that should be tested are, but are not limited to:
Glow Pins
Control Units
Fuel Metering Pumps
Temperature, Flame and Overheat Sensors
Combustion Air Blowers
Coolant Pumps
Thermostats and Timers
Mini Controllers
Wire Harnesses
Espar assumes that the technical repair is carried out without fault and economically, i.e. replacement
of only those parts that are defective, settlement of only those labour costs incurred (according to Flat
Rate Labour Guide). Duplicate expenses, for example two journeys because the spare part was not
available, cannot be claimed.
