The function of the temperature and pressure relief valve is to discharge water in quantities should circumstances demand. If the discharge pipe is not directed to drain as shown in Figure 2A, or other suitable means, the water flow may cause property damage. The discharge line: 1. must not be smaller than the outlet pipe size of the relief valve, 2. must not be plugged or blocked, 3. must be material capable of withstanding 99°C (210°F) without distortion, 4. must be installed so as to allow complete drainage of both temperature and pressure relief valve, 5. must terminate at an adequate drain, and 6. must not have any valve between the relief valve and the water heater. Closed system/Thermal expansion Periodic discharge of the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure-reducing valve. This will create a closed water system. During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. This may cause the temperature and pressure relief valve to discharge small quantities of hot water. To prevent this, it is recommended that a diaphragm-type expansion tank (suitable for potable water) be installed on the cold water supply line. The expansion tank must have a minimum capacity of 5.6 litres (1.5 US gallons) for every 190 litres (50 US gallons) of stored water and be rated at the working pressure of the water heater. Contact the local water supplier or plumbing inspector for information on other methods to control this situation. Important: Do not plug or remove the temperature and pressure relief valve. Installation Checklist Check Here 1. Have the vent location limitations and minimum height for vent termination and maximum vent length been checked? 2. Are the terminal and vent pipes installed and sealed properly? 3. Has the gas piping been leak tested? 4. Is there 508mm (20 in.) at the top and 25mm (1 in.) around the vent pipe? 5. Have you taken steps to prevent water damage in case of leaks? 6. Is the diptube installed in the cold water inlet connection? 7. Is the water heater completely filled with water? 8. Does the gas piping conform with the recommendations of your Local Gas Utility Company? 9. Is the vent terminal opening unobstructed? 10. Is a temperature and pressure relief valve installed? 11. Is the drain pipe from the T&P valve unobstructed? 12. Has all plastic and cardboard packaging material been removed from the heater and venting? If the answer to all of the questions above is “Yes”, read the Operating Instructions and proceed with lighting the heater. – 10 – IV) OPERATING INSTRUCTIONS IV) OPERATING INSTRUCTIONS Lighting instructions (Robertshaw 110R) FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosionmay result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by igniter. When lighting a pilot, follow these instructions exactly. B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electric switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions. • If you cannot reach your gas supplier, call the fire department. C. Use only your hand to turn the gas control knob. Never use tools. If the knob will not turn by hand, don't try to repairit, call a qualified service technician. Force or attempted repair may result in a fire or explosion. D. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspectthe appliance and to replace any part of the control system and any gas control which has been under water.
