If not, heater will move when you adjust controls. Moving heater may cause a gas leak. A WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fireplace floor to allow access to heater control panel. This will insure adequate air flow and guard against sooting. Raise fireplace floor with non-combustible material. Make sure material is secure. Jtik, CAUTION: Do not pick up heater base assembly by the burner. This could damage heater. Only handle base assembly by grates. IMPORTANT.'Make sure the heater burner is level. If heater is not level, heater will not work properly. Installation Items Needed • hardware package (provided with heater) • approved flexible gas hose (not provided) (if allowed by local codes) • sealant (resistant to LP gas, not provided) • electric drill with 3/16" drill bit (metal or masonry as applicable) • flatheaded screwdriver Continued 104256 9 VANGUARD FLAME-MAX™ UNVENTED PROPANE/LP GAS LOG HEATER INSTALLATION Continued 1. Apply pipe joint sealant lightly to male threads of the fitting to be threaded into gas regulator. Connect approved flexible gas hose to gas regulator of heater (see Figure 11). IMPORTANT: Hold gas regulator with wrench when connecting flexible gas hose. 2. Locate two masonry screws in hardware package. 3. Position heater base assembly in fireplace. 4. Mark screw locations through one hole on each side of the mounting bracket (see Figure 12). If installing in a brick-bottom fireplace, mark screw locations in mortar joint of bricks. 5. Remove heater base from fireplace. 6. Drill holes at marked locations using 3/16" drill bit. 7. Attach base assembly to fireplace floor using two masonry screws (in hardware package). 8. Connect to gas supply. See Connecting To Gas Supply, column 3. Heater Gas Regulator Standard Oak Log Chassis CONNECTING TO GAS SUPPLY Flexible Gas Hose (if allowed by local codes) Figure 11 - Attaching Flexible Gas Hose to Heater Gas Regulator Masonry Screw Bracket with Screw Holes Golden Oak and Birch Model Chassis Masonry Screw Screw Holes Figure 12 - Attaching Base Assembly to Fireplace Floor NOTICE: A qualified service person must connect heater to gas supply. Follow all local codes. A CAUTION: Never connect heater directly to the propane supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane supply. installation Items Needed Before installing heater, make sure you have the items listed below. • external regulator (supplied by installer, see above) • piping (check local codes) • sealant (resistant to LP gas) • manual shutoff valve * • test gauge connection * • sediment trap • tee joint • pipe wrench • An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer. See Accessories, page 19. 10 104256 OWNER’S MANUAL INSTALLATION Continued 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.

This gas is commonly known as well-head gas. A 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 14). 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 likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. I...
