Heavy demands are made on the controls when direct ignition systems are used on central heating equipment in barns, greenhouses, and commercial properties and on heating appliances such as commercial cookers, agricultural equipment, industrial heating equipment and pool heaters. Special steps may be required to prevent nuisance shutdowns and control failures due to frequent cycling, severe environmental conditions related to moisture, corrosive chemicals, dust or excessive heat.
Features:
- Controls include manual valve, two automatic operators, and pressure regulator.
- Provide two automatic valves.
- Solenoid operated first automatic valve opens on thermostat call for heat; closes when call for heat ends.
- Diaphragm operated second automatic valve opens under control of the regulator; closes if gas or power supply is interrupted.
- Meet codes requiring dual safety shutoff.
- Natural to LP and LP to Natural conversion kits available for standard and slow opening gas valves.
- Adjustments and wiring connections are accessible from top of the control.
- ON-OFF lighting sequence.
Product Specifications:
- Body Pattern: Straight through.
- Voltage and Frequency: 24 Vac, 60 Hz or 50/60 Hz depending on model.
- Current Draw: 0.5A with both operators energized.
- Pipe Adapters: Angle and straight adapters available for 3/8-, 1/2- and 3/4-in. pipe. See Table 5. Flange kits include one flange with attached O-ring, four mounting screws, a 9/64 in. hex wrench and instructions.
- Frequent Cycling: this control is designed for use on appliances that typically cycle three to four times an hour only during the heating season. In year-around applications with greater cycling rates, the control can wear out more quickly.
- If a control gets wet, replace it. If the appliance is likely to be cleaned with water or steam, protect (cover) the control and wiring from water or steam flow. Mount the control high enough above the bottom of the cabinet so it does not get wet during normal cleaning procedures.
- Dripping water can cause the control to fail. Never install an appliance where water can drip on the control. In addition, high ambient humidity can cause the control to corrode and fail. If the appliance is in a humid atmosphere, make sure air circulation around the control is adequate to prevent condensation.
- Corrosive chemicals can attack the control, eventually causing a failure. If chemicals are used for routine cleaning, avoid contact with the control. Where chemicals are suspended in air, as in some industrial or agricultural applications, protect the control with an enclosure.
- Heavy accumulations of dust or grease can cause the control to malfunction. Where dust or grease can be a problem, provide covers for the control to limit contamination.
- Excessively high temperatures can damage the control. Make sure the maximum ambient temperature at the control does not exceed the rating of the control. If the appliance operates at very high temperatures, use insulation, shielding, and air circulation, as necessary, to protect the control. Proper insulation or shielding should be provided by the appliance manufacturer; verify proper air circulation is maintained when the appliance is installed.
- Controls with standard, slow-opening, and two-stage regulators (model numbers with suffix letters H, K, M, or Q) can be converted from one gas to the other with a conversion kit.
- Approvals: American Gas Association Design Certificate L2025006; Canadian Gas Association Design Certificate L2025006; Australian Gas Association Design Certificate 4214; Approved for Delta C applications.
