Section 8, Operating the Heating Module

8.12 Maintenance

Customer Monthly Maintenance: Check the following and correct as required:

•Coolant hoses and fittings for leaks and integrity.

•Check coolant level in the overflow bottle (3/4 full when hot). Fill only when the system is COLD and in small quantities only to prevent overfilling.

•Exhaust fittings, connections, tubes for leaks, and integrity.

•Exhaust and air-intake checked for no obstructions.

•Fuel lines, fittings for leaks and integrity.

•External fuel filter for clogging.

Annual Service Requirements: Perform the following:

•Prior to operation for the season, a factory service tune-up of the modular system should be performed by trained service personnel. Only personnel familiar with the equipment modules should perform the service tune-up. It is recommended that the dealer be contacted for this service or if not available, contact ITR for information on service resources.

•As a general guide, the regular maintenance items such as the igniter, fuel filters (internal and external), and air filter (internal) should be replaced as opposed to inspected and cleaned. Their performance may be deteriorating and/or their remaining service life ending without any apparent visual signs or operating symptoms.

•The major components such as the air compressor, fuel pump, fuel nozzle, and combustion air fan should be examined for wear and should be replaced by the service technician as required.

•The combustion tube should be inspected by the service technician for wear and replaced if necessary. To access the combustion tube, the front panel of the Oasis™ must be removed along with the burner box cover. The fuel block must then be removed from its mounting position.
