1 GAS VALVE CROSS REFERENCE 1

2 Looking for a replacement gas valve? Then look for gas valves - the only complete line of combination gas heating valves from 3/8 pipe low capacity models up to 1 high capacity models. combination gas valves feature the reliability, flexibility and convenience you require in a replacement control. The family of combination gas valves has been the industry standard since the introduction of the Unitrol 7000 Series in Offering full line capability in a small size with a wide range of capacities, the 700, 710 and 720 series feature easy installation and service which makes replacement a simple choice. Models are available in 24 Volt combination, 24 Volt diaphragm, millivolt, line Voltage (120 and 240) hydraulic (snap-action or modulating) two-stage manual, and bleed operated. Use this comprehensive pocket guide for an overview of the gas valves available as well as a cross reference tool to thousands of parts. - Simply the right choice for all your gas valve needs.

20 TIPS ON SELECTING A REPLACEMENT GAS VALVE Safety Warning: Any work on gas valves or equipment should be preformed by a qualified service technician only. Please do not attempt any repairs or replacement if you are not qualified. Serious injury can occur from improper installation or usage. Disclaimer: The cross references provided in this booklet are intended to be functional equivalents and not exact matches of products listed. Invensys Controls assumes no liability in connection with the information contained herein and makes no representations regarding the accuracy of any such information. Final selection of a replacement product is the sole responsibility of the buyer. GAS VALVE SELECTION CHECKLIST GUIDELINES Always check the following with any gas valve retrofit application: 1. Check capacity 2. Check inlet and outlet sizes 3. Determine if valve is non-regulated a. Check if the pressure regulator requires adjusting 4. Determine if the replacement requires straight-thru 5. Determine if application is L.P. or Natural Gas a. For L.P. gas, a separate pressure regulator may be required 6. Determine if the pilot needs to be plugged 7. Determine if valve is slow opening 8. Determine if a transformer is required 9. Determine if the replacement shaft and hub will require assembly 10. Check and replacement manuals for proper installation instructions HOW TO READ AND INTERPRET A GAS VALVE LABEL To identify your valve type, locate the red or white factory label on the valve body. Note: It is essential to write down the nine-digit factory number correctly. Manufactured by Model Type Factory No. (9 digits) and Max. PSI Rating Regulator information Application information Number or Number Date Code (Year 09, Week 23) An valve may have an part number instead of the part number. The cross reference on the following pages will cross most nine-digit factory numbers or part numbers to the numbers. Gas valves with white labels are usually manufactured to be used on natural gas applications. Red labels indicate the valves are usually manufactured to be used on L.P. gas applications. Any additional characters after the 9 digit factory number are used for shipping purposes and should be ignored when cross referencing. 20
