Attaching to Wall Stud Method For attaching mounting bracket to wall studs 1. Drill holes at marked locations using 9/64" drill bit. 2. Place mounting bracket onto wall. Line up last hole on each end of bracket with holes drilled in wall. 3. Insert mounting screws through bracket and into wall studs. 4. Tighten screws until mounting bracket is firmly fastened to wall studs. Attaching to Wall Anchor Method For attaching mounting bracket to hollow walls (wall areas between studs) or solid walls (concrete or masonry) 1. Drill holes at marked locations using 5/16" drill bit. For solid walls (concrete or masonry), drill at least 1" deep. 2. Fold wall anchor as shown in Figure 9 below. Figure 9 - Folding Anchor 3. Insert wall anchor (wings first) into hole. Tap anchor flush to wall. 4. For thin walls (1/2" or less), insert red key into wall anchor. Push red key to "pop" open anchor wings (see Figure 10). IMPORTANT: Do not hammer key! For thick walls (over 1/2" thick) or solid walls, do not pop open wings. Figure 10 - Popping Open Anchor Wing For Thin Walls 5. Place mounting bracket onto wall. Line up last hole on each end of bracket with wall anchors. 6. Insert mounting screws through bracket and into wall anchors. 7. Tighten screws until mounting bracket is firmly fastened to wall. Placing Heater On Mounting Bracket 1. Locate two horizontal slots on back panel of heater (see Figure 11). 2. Place heater onto mounting bracket. Slide horizontal slots onto stand-out tabs on mounting bracket. Figure 11 - Mounting Heater Onto Mounting Bracket Installing Bottom Mounting Screws 1. Locate two bottom mounting holes. These holes are near bottom on back panel of heater(see Figure 12). Figure 12 - Installing Bottom Mounting Screws 2. Mark screw locations on wall. 3. Remove heater from mounting bracket. 4. If installing bottom mounting screws into hollow or solid wall, install wall anchors. Follow steps 1 through 4 under Attaching To Wall Anchor Method. If installing bottom mounting screw into wall stud, drill holes at marked locations using 9/64" drill bit. 5. Replace heater onto mounting bracket. 6. Place spacers between’ bottom mounting holes and wall anchor or drilled holes. 7. Hold spacer in place with one hand. With other hand, insert mounting screw through bottom mounting hole and spacer. Place tip of screw in opening of wall anchor or drilled holes. 8. Tighten both screws until heater is firmly secured to wall. Do not over tighten. Note: Do not replace lower front panel at this time. Replace lower front panel after making gas connections and checking for leaks(see page 10) . 8 INSTALLATION CONNECTING TO GAS SUPPLY WARNING: A qualified service person must connect heater to gas supply. Follow all local codes. WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator. 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 to 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 13. Pointing the vent down protects it from freezing rain or sleet. Figure 13 - 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 of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur. Typical Inlet Pipe Diameters All models up to 20,000 BTU’s use 3/8’’ or greater pipe; All models 25,000 BTU’s and higher, use 1/2” or greater pipe. Installation must include an equipment 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 14). IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. Figure 14 -Gas Connection From External LP Gas Regulator *A CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA/AGA design-certified equipment shutoff valve from your dealer. See Accessories, page 17. 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 14. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likel...
