SECTION 1 SECTION 2 Introduction Planning Ener-Radiant ERXL models are low-cost, field assembled infrared heaters that are easy to install and require only minimal maintenance. They are designed to provide years of economical operation and trouble-free service. The following codes and instructions should be followed when planning the installation of the Ener-Radiant ERXL heater.
• When installed over hoists, minimum clearances to combustibles must be maintained from the uppermost point on the hoist. • Be sure the heater has a downward pitch of one-half inch per 20 feet away from the burner. • Provide signs in storage areas to specify maximum stacking height to maintain required clearances to combustibles. Electrical: The heater must be electrically grounded in accordance with the National Electrical Code, ANSI / NFPA-70 – latest revision.

Section 4 recommended with unvented heaters due to pressure considerations. Horizontal Venting Venting / Ducting a) In combustible or noncombustible walls, use Tjerblund VH1-4” (Stk. #19022). Follow vent manufacturer’s instructions for proper installation. (Alternative vent Enerco Stk. #19023). b) Four (4”) inch O.D. flue pipe is required. Thirty (30’) feet maximum length is recommended. Up to forty-five (45’) feet maximum may be used if insulated to prevent excess condensation.

Section 7 7. Check the flue pipe for soot or dirt. After cleaning as necessary, re-attach the flue pipe to the heater. Operation & Maintenance 8. Outside surfaces of heater may be cleaned by wiping with a damp cloth. Sequence of Operation 9. A qualified service agency should be contacted for service other than routine maintenance. 1. Turn the thermostat up. When the thermostat calls for heat, blower motor will energize. 2.
Natural outlet pressure should be 3.5” Honeywell Valve LED Status LP inlet pressure should be 11.0” The Ener-Radiant XL series Tube Heater is equipped with a honeywell Smart Valve. This valve has a built-in diagnostic program, which will assist in troubleshooting in the event of a valve-related problem. The LED or (Light Emitting Diode) is located on the top of the valve as shown in diagram below. The LED status indications are listed below to help with the troubleshooting.
SECTION 8: Troubleshooting Guide. Ener-Radiant XL START Turn on thermostat Does blower turn on? Check Thermostat and Wiring. Is the Yes power supply to unit 115V? No Is blower side door in place? No Find the source of the electrical problem Yes Is the air intake or exhaust blocked? No Remove door. Is voltage at door switch 115V? No Replace door Check voltage at gas valve. Check voltage to motor. Is it 115V? No Check wiring and hose connection to air switch.
