ZONE CONTROL PANEL COMPONENT FUNCTION AND INSTALLATION The zone control panel is a remote mounted control system allowing the operation of a specific amount of heaters within a certain zone of the building. These panels will control the following quantity of heaters depending on fuel type. Model and Heat Output I34 (34,200 BTUH) Modulating System Fuel L. P.
WARNING Fire or Explosion Hazard Start-Up Instructions FIG. 7 THERMOSTATIC HEAD ■ Do not force the safety gas control valve button. ■ Use only your hand to depress the gas control button. Never use any tools. ■ If the button will not depress by normal hand pressure, the control should be replaced by a qualified service person. ■ Force or attempted repair may result in fire or explosion, causing property damage, severe injury, or death.
Cleaning Instructions CAUTION ■ Disinfectants utilized in agricultural animal confinement buildings may contain chemicals damaging to components of the heater. ■ Protect the safety gas control valve and pressure valve by wrapping these components with a plastic bag before disinfecting. 5. Inspect the cones and venturi tube to make sure these areas are clean. 6. Return the heater to its normal hanging position and relight the heater. FIG.
FIG. 11 WATER HOSE 8. Relight the heater to dry out the cones and the venturi tube. B. FILTER A. During continued use: - Remove filter and shake off dust. - Do not squeeze or tap filter while filter is installed on heater. Doing so will cause dust to be blown into venturi tube or combustion cones. B. After continued use or before building repopulation: 4. Repeat steps 2 and 3 until water runs clean. 5. Remove the plastic bag. Inspect the cones and venturi tube to make sure these areas are clean. 6.
Maintenance Instructions 1. Have your gas supplier check all gas piping annually for leaks or restrictions in gas lines. Also, at this time have your gas supplier clean out the sediment trap on the zone control panel of any debris that may have accumulated. 6. If any warning or instruction labels, dataplates, etc. become lost or hard to read, replace them immediately. Do not operate the heater until you have all instructions and can read and understand them. 3.
1. Disconnect the gas hose. 2. Loosen the gas supply tube compression nut and swing the tube away from the safety control valve. FIG. 12 SAFETY GAS CONTROL VALVE PILOT SAFETY VALVE SAFETY CONTROL VALVE BYPASS GAS TUBE SUPPLY TUBE GAS SUPPLY 3. Remove the thermocouple from the safety control valve. SCREW 4.
