5. Startup and Operation Once setup properly, the XT 75 is designed to operate reliably over a wide range of conditions with minimal adjustment. This section is provided to make sure that the heater is set up properly, and to provide instructions on the initial startup. 5.1 Do’s and Don’ts/Tech Tips 1. -
Page 21: Safety Systems And Warnings
5.3 Safety Systems and Warnings Several systems built into the burner controls ensure that the burner operates safely and will shut down if something is wrong: Fuel Preheater Control: This device prevents the oil from being overheated by the preheater in the nozzle block assembly. -
Page 22: Heater Startup
5.4 Heater Startup Prior to the initial startup of the heater, make sure the power has been on at least 10 minutes for the nozzle block to heat up. Once the burner is operating, the system should be checked and necessary adjustments made. It takes some time for fuel to reach the nozzle and push all the air out of the system. -
Page 23: Burner System Checkout
5.4.2 Burner System Checkout Once the heater starts operating, make the following checks and adjustments: If you are unable to obtain the proper adjustments, do not run the heater. If you cannot resolve the issue, call Technical Support for assistance. Fan Operation: Within the first few minutes after the burner fires, make sure that the fan begins to operate and directs warm air into the room. - Page 24 Note: The draft gauge should read 0.0 inches of WC when the probe is removed from the stack. (If not, make sure the gauge is level, and readjust the zero knob). If the heater is not running, the draft gauge with the probe installed into the stack will not necessarily read zero, depending on ambient conditions.
- Page 25 Air Pressure: The burner has a built-in air compressor to provide pressurized air for oil atomization at the nozzle. The air pressure is set at the factory to 3 - 4 psi. If the pressure has drifted and a pressure adjustment is required, loosen the 3/8” nut on the bleeder valve, adjust the stem with a small screwdriver, and tighten the nut to lock it in place.
