HE+ Series Infrared Gas Heater Installation and Operation Manual

13. ELECTRICAL AND THERMOSTAT WIRING (WIRING DIAGRAMS: SEE SUPPLEMENTARY MANUAL)

The heater must be electrically grounded in accordance with the National Elec-

trical Code. ANSI / NFPA 70.

Appliance and control wiring must be in accordance with all applicable local codes. The total load of all heaters

must be considered in determining the required contact rating of the controlling thermostat or switch. Each

tube heater requires 120V, 60 HZ electrical power sized for 145VA. Maximum power flow for internal 24V burn-

er components is 21VA.

The Fenwal ignition control includes a 24V/120V relay switch that provides a 45 second pre-purge and 45 sec-

ond post-purge of the system. To maintain function of the post-purge feature, any Thermostat / control must

be installed in the thermostat circuit from the terminal block (TR - TW). A line voltage Thermostat or an

“ON/OFF” control switch installed in the 120VAC power supply will disable the post-purge feature.

A maximum night set-back of 9°F (5°C) is recommended for optimum economy and comfort. To maintain satis-

factory comfort levels do not turn off the heating system over night/weekends.

14. HIGH ALTITUDE INSTALLATIONS - for recommended orifice sizing, and re-

strictions refer to the High Altitude Section in the Supplementary Manual includ-

ed for this specific model

When installed above the altitude stipulated below, the input must be de-rated by 4% for each 1000 ft above the

altitude listed. Refer to the tables in Section 28 for orifice size and restrictions that apply to high altitude installa-

tion (including total system length restrictions). Check with your local utility regarding the gas supply and the de-

rating of this appliance.

USA: The factory installed orifice for this appliance is approved for altitudes zero to 2000 feet above sea lev-

el. When installed above 2000 feet, refer to the Supplementary Model Manual Section 15.

15. LIGHTING INSTRUCTIONS

Refer to the lighting instructions label on the outside of the burner housing. If the unit locks out on safety, main

power to the unit must be manually interrupted for a 30 second reset period before the heater can be restarted.

NOTE: On initial installation, the unit may lock out on safety owing to the length of time required to

bleed air from the gas piping system.

16. RECOMMENDED MAINTENANCE

Improper adjustment, alteration, service or maintenance can cause property damage, injury or death. This heat-

er must be installed and serviced only by a trained gas service technician.

1. Inspect the entire heater system, venting, and gas supply connections at least annually prior to the

heating season. Replace worn parts and repair deficiencies.

2. Check the inlet air opening and the blower periodically, cleaning off any lint or foreign matter. It is important

that the flow of combustion and ventilation air must not be obstructed.
