21 Section 5 Vent / Ducting VENTING / DUCTING Section 5 General Requirements Heater must be vented in accordance with specification ANSI Z223.1 - latest revision. Partial information relating to this specification is provided in this section with regard to size and configurations for venting arrangements ( see Figures 12, 13, 14, 15, 16). For complete information consult ANSI Z223.1 - latest revision and applicable local codes.
Section Section 5 Venting / Ducting Alternative Arrangements / Optional Equipment for Venting Unvented Operation a) Sufficient ventilation must be provided in the amount of 4 CFM per 1,000 BTU/hr. firing rate. b) Refer to ANSI Z223.1 - latest revision, NPFA-54 and local codes for additional information. c) Use of optional outside combustion air is not recommended with unvented heaters due to pressure considerations.
23 Section 5 Vent / Ducting FIGURE 12: Unvented Operation 1) Ventilation equal to 4 CFM per 1,000 BTU/hr. firing rate must be provided in unvented heater installations. 2) For dimensions A “unvented” refer to (Figure 1 -- Minimum Clearances to Combustibles).

Section Section 5 Venting / Ducting 16 Outside Combustible Air supply The Ener-Radiant XL heater is approved for installation with an outside air supply system. Some compounds such as halogenated hydrocarbons or other corrosive chemicals in the air can be drawn into the equipment and cause an accelerated rate of corrosion of some of the heater components. The use of such chemical compounds near the enclosure should be avoided.
27 Section 6 Gas Piping GAS PIPING Section 6 Read applicable warnings in (Section 1) before proceeding with Gas Pipe installation. Improper installation may result in property damage, severe injury or death. Meter and service must be large enough to handle all the burners being installed plus any other connected load. the gas line which feed the system must be large enough to supply the required gas with a maximum pressure drop of 1/2” water column.
Section 7 WIRING Wiring 28 Section 7 Heaters are normally controlled by thermostats. Line voltage thermostats are wired directly ( see Feigure 18a), the recommended 24V thermostats use a relay (see Figure 18b). Heaters must be grounded in accordance with the National Electrical Code ANSI/NFPA-70 - latest revision. Heaters may also be controlled with a manual line voltage switch or timer switch in place of the thermostat.
29 Section 7 Wiring FIGURE 19: Wiring of Low Voltage Thermostat and Relay When usung 1 - 2 burners, use SPDT Transformer Relay / Stk. #00172 When using 3 - 4 burners, use DPDT Transformer Relay / Stk. #00183 Wires marked with an asterisk (*) are for use only with the DPDT Transformer Relay. 18677 Rev.
Section 7 FIGURE 20: Wiring 30 Ener-Radiant XL Burner Internal Wiring • If any of the original wire as supplied with the appliance must be replaced, it must be replaced with wiring material having a temperature rating of at least 105o C and 600 volts. • Each burner must be electrically grounded in accordance with the National Electrical Code ANSI / NFPA-70 - latest revision. 18677 Rev.

Section 8 Section Operation & Maintenance OPERATION & MAINTENANCE 32 Section 8 Sequence of Operation 1. Turn the thermostat up. When the thermostat calls for heat, blower motor will energize. 2. When the motor approaches nominal running RPM, the air proving switch closes and activates the ignition module. 3. The ignition module then energizes the hot surface igniter for a timed warm-up period (approximately 45 to 60 seconds). 4. After the warm-up period, the gas valve is energized. 5.
33 Section 8 Operation & Maintenance Troubleshooting CAUTION: Before opening the Ener-Radiant XL burner door for any type of service, be sure the gas supply has been shut off at the heater and the electrical cord from the burner box has been unplugged. Blower Motor Fails to Run: 1. Is the thermostat calling for heat? Is there 115V at the burner receptacle? 2. Check blower side door for seal. Check door switch. Replace if necessary. 3. Check blower for obstructions. Replace blower if necessary.
Section 8 Section Operation & Maintenance 34 Honeywell Valve LED Status 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.
