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. External Regulator Propane Supply Tank Vent Pointing Down Figure 12 - External Regulator With Vent Pointing Down 10 104307 OWNER’S MANUAL INSTALLATION Continued CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" 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, 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). 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. A.G.A. Design-Certified Manual Install sediment trap in supply line as shown in Figure 13. 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. CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings. CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections for leaks after installing 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. * Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer. See Accessories, page 21. ** Minimum inlet pressure for purpose of input adjustment.

Pressure) Shutoff Valve With 1/8" NPT Tap* Approved Flexible Gas Hose (if allowed by local codes) CAUTION: Make sure external regulator has been installed between propane supply and heater. See guidelines underConnecting to Gas Supply, page 10. 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. 3. Pressurize supply piping system by either using compressed air or opening propane 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. 6. Re-connect heater and manual shutoff valve to gas supply. Check re-connected fittings for leaks. Test Pressures Equal To or Less Than 1/2 PSIG 1. Close manual shutoff valve (see Figure 14, page 12). 2. Pressurize supply piping system by either using compressed air or opening propane supply tank valve. 3. Check all joints from propane supply tank to manual shutoff valve (see Figure 15, page 12). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 4. Correct all leaks at once. Continued 104307 11 CGD3924PR, CGB3924PR and CGB3930PR UNVENTED PROPANE/LP GAS LOG HEATER INSTALLATION 4. Continued Pressure Testing Heater Gas Connections 5. 1. Open manual shutoff valve (see Fig6. ure 14). 2. Open propane supply tank valve. 3. Make sure control knob of heater is in 7. the OFF position.

Check all other internal joints for leaks. Turn off heater (see To Turn Off Gas to Appliance, page 16). Propane Tank Thermostat Gas Valve or Control Valve Location Figure 15 - Checking Gas Joints 9-VOLT BATTERY INSTALLATION Two 9-volt alkaline batteries (not included) are required to operate this heater with the wireless hand-held remote control set. One battery must be installed in the receiver and one in the hand-held remote control unit. Note:Only use alkaline batteries. Installing 9-Volt Alkaline Battery In Receiver 1. Locate back of receiver under front burner of heater. 2. Locate the battery clip mounted on the back of the receiver. 3. Slide a 9-volt alkaline battery through the clip. 4. Attach the teminal wires to the battery. Figure 16 - Installing 9-Volt Battery In Receiver Receiver Terminal Wi...
