14104060COMPACT CLASSIC HEARTH FIREPLACEVMH26TNA®CONNECTING TO GASSUPPLYWARNING: A qualified ser-vice person must connect fire-place to gas supply. Follow alllocal codes.IMPORTANT: Check gas line pressure be-fore connecting fireplace to gas line. Gasline pressure must be no greater than 14inches of water. If gas line pressure is higher,fireplace regulator damage could occur.Installation must include a manual shutoffvalve, union, and plugged 1/8" NPT tap.Locate NPT tap within reach for test gaugehook up. NPT tap must be upstream fromfireplace (see Figure 22).IMPORTANT: Install main gas valve(manual shutoff valve) in an accessiblelocation. The main gas valve is for turningon or shutting off the gas to the appliance.We recommend that you install a sedimenttrap in supply line as shown in Figure 22.Locate sediment trap where it is withinreach for cleaning. Install in piping systembetween fuel supply and heater. Locate sedi-ment trap where trapped matter is not likelyto freeze. A sediment trap traps moistureand contaminants. This keeps them fromgoing into fireplace controls. If sedimenttrap is not installed or is installed wrong,fireplace may not run properly.WARNING: Never connectfireplace to private (non-utility)gas wells. This gas is commonlyknown as wellhead gas.CAUTION:Use only new,black iron or steel pipe. Inter-nally-tinned copper tubing maybe used in certain areas. Checkyour local codes. Use pipe of1/2" or greater diameter to al-low proper gas volume to fire-place. If pipe is too small, un-due loss of pressure will occur.CAUTION: Use pipe joint seal-ant that is resistant to liquid pe-troleum (LP) gas.Attaching Wood Base to SolidFloorFor attaching base to solid floors (concreteor masonry)Note: Floor anchors and mounting screwsare in hardware package. The hardwarepackage is provided with fireplace.1. Drill holes at marked locations using5/16" drill bit. For solid floors (con-crete or masonry), drill at least 1" deep.2. Fold floor anchor as shown in Figure 21.3. Insert floor anchor (wings first) intohole. Tap anchor flush to floor.4. Insert mounting screws through baseand into floor anchors.5. Tighten screws until base is firmly fas-tened to floor.Figure 21 - Folding AnchorINSTALLATIONContinuedApply pipe joint sealant lightly to malethreads. This will prevent excess sealantfrom going into pipe. Excess sealant in pipecould result in clogged fireplace valves.* Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer.See Accessories, page 27.A.G.A.
