Resumen del manual


If installing bottom mounting screw into wall stud, drill hole at marked location using 9/64" drill bit. 5. Replace heater on wall. 6. Insert bottom anchor screw through back panel into bottom anchor or drilled hole (see Figure 11). 7. Tighten screw until heater is firmly secured to wall. Do not over tighten. Note:Do not replace front panel at this time. Replace front panel after making gas connections and checking for leaks (see pages 13-15). Figure 11 - Installing Bottom Mounting Screw CONNECTING TO GAS SUPPLY NOTICE A qualified service person must connect heater to gas supply. Follow all local codes. CAUTION Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply. The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 12. Pointing the vent down protects it from freezing rain or sleet. Propane/LPSupply Tank External Regulator Vent Pointing Down Figure 12 - External Regulator With Vent Pointing Down CAUTION Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe 3/8" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur. Installation must include a manual shutoff valve, ground joint union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 13, page 14). Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. CAUTION Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. Install sediment trap in supply line as shown in Figure 13, page 14. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly. Continued CONNECTING TO GAS SUPPLY Continued CHECKING GAS CONNECTIONS IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.

Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer. See Accessory, page 28.

WARNING Test all gas piping and connections for leaks after installation or servicing. Correct all leaks at once. WARNING Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once. CAUTION Make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, page 13. PRESSURE TESTING GAS SUPPLY PIPING SYSTEM Test Pressures In Excess Of 1/2 PSIG 1. Disconnect heater and its individual manual shutoff valve from gas supply piping system. Pressures in excess of 1/2 Psig will damage heater regulator. 2. Cap off open end of gas pipe where manual shutoff valve was connected. 14 CHECKING GAS CONNECTIONS Continued 3. Pressurize supply piping system by either using compressed air or opening propane/LP supply tank valve. 4. Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 5. Correct all leaks at once. Test Pressures Equal To or Less Than 1/2 PSIG 1. Close manual shutoff valve (see Figure 14). 2. Pressurize supply piping system by either using compressed air or opening propane/LP supply tank valve. 3. Check all joints from propane/LP supply tank to manual shutoff valve (see Figure 15). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 4. Correct all leaks at once. PRESSURE TESTING HEATER GAS CONNECTIONS 1. Open manual shutoff valve (see Figure 14). 2. Open propane/LP supply tank valve. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from manual shutoff valve to control valve (see Figure 15). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6.
