CAUTION Make sure external regulator has been installed between propane supply and heater. See guidelines under Connecting to Gas Supply, page 11. 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 pipe. 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. Test Pressures Equal To or Less Than 1/2 PSIG 1. Close manual shutoff valve (see Figure 8). 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. 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 8). 2. Open propane 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 on heater. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6.

On Position Off Position Continued Figure 8 - Manual Shutoff Valve INSTALLING HEATER Continued INSTALLING GLASS PANEL 1. Locate the glass panel package inside the back of the heater. CAUTION Before installing glass panels, inspect the edges. If you notice any chips or cracks, do not install. If the surface on either side is deeply scratched, do not install. If these conditions exist, contact your Vanguard dealer for replacement glass panels. CAUTION Do not operate heater without glass panels installed. Operating heater without glass panels will damage front of heater due to excess temperatures. CAUTION Glass panels may have sharp edges. Handle with care. 2. Remove lower front access panel of heater by removing two screws at upper corners of panel. The lower front access panel covers the lower front access area (see Figure 9). 3. Remove two screws on glass guard. Remove glass guard (see Figure 9). 4. Carefully insert one glass panel up through lower front access area (see Figure 10, page 15). 5. Carefully slip glass panel behind hearth assembly (see Figure 10, page 15). Glass Guard Lower Front Access Panel Figure 9 - Removing Lower Front Access Panel 14 INSTALLING HEATER Continued 6. Insert top edge of glass panel into the upper glass retaining channel (see Figure 11). Glass Panel Hearth Assembly Lower Front Access Area Figure 10 - Inserting Glass Panels CAUTION Make sure you insert top edge of glass panels into the upper glass retaining channel. Do not install glass panels with top edge of glass in front of the upper glass retaining channel. Glass panels will not automatically go into the channel. You must guide the glass panels into it. Incorrect installation will damage front of heater due to excess temperatures. 7. Lower glass into lower glass retaining channel (see Figure 12). Slide glass panel all the way to the left side. Note:If you have chipped or cracked a glass panel during installation, do not use. Contact your Vanguard dealer for a replacement glass panel. 8. Repeat steps 4 through 7 for all glass panels. 9.
