The equipment shutoff valve is for turning on or shutting off the gas to the appliance. Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. Install sediment trap in supply line as shown in Figure 15, page 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. External Regulator Propane/LP Supply Tank Vent Pointing Down Figure 14 - External Regulator With Vent Pointing Down 114683-01B INSTALLATION Continued IMPORTANT: Hold the pressure regulator with wrench when connecting it to gas piping and/or fittings. Do not over tighten pipe connection to regulator. The regulator body could be damaged. Pressure WARNING: Never use an open flame to check for a leak. Applyanoncorrosiveleakdetection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once. CAUTION: For propane/LP gas, make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, page 12.

Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air. 3. Check all joints from gas meter for natural gas (see Figure 17) or propane/LP supply tank for propane/LP gas, to equipment shutoff valve (see Figure 18). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. 4. Correct all leaks at once. PRESSURE TESTING HEATER GAS CONNECTIONS 1. Open equipment shutoff valve (see Figure 16, page 13). 2. For natural gas open main gas valve located on or near gas meter. For propane/LP gas open propane/LP supply tank valve. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from equipment shutoff valve to thermostat gas valve (see Figure 17 or 18). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6. Light heater (see Operating Heater, starting on page 15). Check all other internal joints for leaks. 7. Turn off heater (see To Turn Off Gas to Appliance, page 16 or 17, depending on your model heater). 8. Replace front panel.
