Locate bottom mounting hole. This hole is near bottom on backpanel of heater (see Figure 9).2. Mark screw location on wall.3. Remove heater from wall.4. If installing bottom mounting screw into hollow or solid wall,install wall anchor. Follow steps 1 through 5 under Attaching ToWall Anchor Method, page 5. If installing bottom mounting screwinto 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 bottomanchor or drilled hole (see Figure 9).7. Tighten screw until heater is firmly secured to wall. Do notover tighten.Note: Do not replace front panel at this time. Replace frontpanel after making gas connections and checking for leaks (seepages 9 and 10).WARNING: Review and understand the warningsin theSafety Information section, page 2. They areneeded to safely operate this heater. Follow all localcodes when using this heater.IMPORTANT: You must use a propane/LP gas supply cylinder thatis compatible with the connection device provided with the hose andregulator.1. Provide propane/LP supply system (see Propane/LP Supply,page 4).WARNING: Test all gas piping and connectionsfor leaks after installation or servicing. Never use anopen flame to check for a leak. Apply a noncorrosiveleak detection fluid to all joints. Bubbles formingshow a leak. Correct all leaks at once.CONNECTING TO PORTABLE CYLINDERGAS SUPPLYFigure 9 - Installing Bottom Mounting Screw2. Connect fuel gas fitting on hose/regulator assembly to pro-pane/LP tank(s). Turn fuel gas fitting counterclockwise intothreads on tank. Tighten firmly using a wrench.IMPORTANT:Position regulator so that hose leaving the regulator is in ahorizontal position (see Figure 10). This places the regulatorvent in the proper position to protect it from the weather.3. Connect hose to heater inlet. Tighten firmly using a wrench.You must use the regulator supplied with heater.4. Open propane/LP supply valve on propane/LP tank(s) slowly.Note: If not opened slowly, excess-flow check valve on pro-pane/LP tank may stop gas flow. If this happens, close pro-pane/LP supply valve and open again slowly.5. Check all connections for leaks. Apply a noncorrosive leakdetection fluid to gas joints. Bubbles forming show a leak thatmust be corrected.6. Close propane/LP supply valve.
