Introduction Roberts-Gordon pioneered low-intensity infrared heating systems in 1962 with the introduction of its revolutionary custom-engineered CORAYVAC® system. Now RobertsGordon offers over 35 years of infrared expertise in an economical vacuum system. VANTAGE ® EV model heaters are low-cost, noncondensing, field assembled vacuum-assisted heating systems that are easy to install and require only minimal maintenance.
ROBERTS-GORDON SECTION Electrical 3: PLANNING–CODES pg 3 Hazardous Locations WARNING WARNING Electrical Shock Hazard Heater must be installed and grounded according to national codes. Failure to follow these instructions will result in death or electrical shock. The heater must be electrically grounded in accordance with the following codes: United States: Refer to National Electrical Code, ANSI/NFPA-70 - latest revision.

pg 36 VANTAGE® EV ROBERTS-GORDON I N S TA L L AT I O N M A N U A L Setting the Vacuum 1. Set thermostats above room temperature. See that all burners are operating properly. Check the vacuum differential at all burners, then adjust the damper coupling to obtain approximately equal vacuum differential readings. Then adjust the pump inlet damper until vacuum differential readings are a minimum 0.5" to 0.6" w.c..
ROBERTS-GORDON SECTION 12: O P E R AT I O N pg 37 Sequence of Operation Burner Sequence of Operation Sequence of Operation (no control panel) 1. When sufficient vacuum differential (minimum 0.5" w.c.) is available at the burner, and the control system is supplying line voltage to the burner, the air sensing switch within the burner closes and energizes the direct spark ignition module. 1. Thermostat, on a call for heat, energizes the relay coil, closing the relay contacts. 2.
After a 45 pre-purge period, does the burner light? Yes Turn up thermostat. Does the pump turn on? No No Yes Yes Yes Repair or Replace switches as necessary. Replace main control board.
