Figure 10 Figure 9 ANCHOR SCREW LOCATIONS INSTALLING AS A VENTED APPLIANCE BEFORE FULLY INSTALLING THE APPLIANCE GAS SUPPLY Check all local codes for requirements, especially for the size and type of gas supply line required. Recommended Gas Pipe Diameter Pipe Length Schedule 40 Pipe Tubing, Type L Inside Diameter Outside Diameter Nat. L.P. Nat. L.P. 0-10 feet 1/2” 3/8” 1/2” 3/8” 0-3 meters 12.7mm 9.5mm 12.7mm 9.5mm 10-40 feet 1/2” 1/2” 5/8” 1/2” 4-12 meters 12.7mm 12.7mm 15.9mm 12.7mm 40-100 feet 1/2” 1/2” 3/4” 1/2” 13-30 meters 12.7mm 12.7mm 19mm 12.7mm 100-150 feet 3/4” 1/2” 7/8” 3/4” 31-46 meters 19mm 12.7mm 22.2mm 19mm Note: Never use plastic pipe. Check to confirm whether your local codes allow copper tubing or galvanized. Note: Since some municipalities have additional local codes, it is always best to consult your local authority and installation code. Installing a New Main Gas Cock Each appliance should have its own manual gas cock. A manual main gas cock should be located in the vicinity of the unit. Where none exists, or where its size or location is not ad equate, contact your local authorized installer for installation or relocation. Compounds used on threaded joints of gas piping shall be resistant to the action of liquefied petroleum gases. The gas lines must be checked for leaks by the installer. This should be done with a soap solution watching for bubbles on all exposed connections, and if unexposed, a pressure test should be made. Never use an exposed flame to check for leaks. Appliance must be disconnected from piping at inlet of control valve and pipe capped or plugged for pressure test. Never pressure test with appliance connected; control valve will sustain damage! A gas valve and ground joint union should be installed in the gas line upstream of the gas control to aid in servicing. It is required by the National Fuel Gas Code that a drip line be installed near the gas inlet. This should consist of a vertical length of pipe tee connected into the gas line that is capped on the bottom in which condensation and foreign particles may collect. Figure 11 The use of the following gas connectors is recommended: — ANSZ21.24ApplianceConnectorsofCorrugatedMetalTubing and Fittings — ANS Z21.45 Assembled Flexible Appliance Connectors of Other Than All-Metal Construction The above connectors may be used if acceptable by the authority havingjurisdiction.ThestateofMassachusettsrequiresthataflexible appliance connector cannot exceed three feet in length. Pressure Testing of the Gas Supply System 1. To check the inlet pressure to the gas valve, a 1/8" (3.175mm) N.P.T.pluggedtapping,accessiblefortestgaugeconnection,must be placed immediately upstream of the gas supply connection to the appliance. 2. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). 3. The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa). Caution: If the gas pressure exceeds the maximum limits listed on page 6 of this manual or on the installed gas valve, it will result in a hazardous condition. Page 12 23099-1-0707 23099-1-0707 Page 13 Before you begin: if you are installing logs onto the VFD(R,T,M)18 or VFD(R,T,M)24 models, this burner assembly is supplied with a set of five ceramic fiber logs. Do not handle these logs with your bare hands! Always wear gloves to prevent skin irritation from ceramic fibers. After handling logs, wash your hands gently with soap and water to remove any traces of fibers. The positioning of the logs is critical to the safe and clean operation of this burner assembly. Sooting and other problems may result if the logs are not properly and firmly positioned on the burner assembly. Refer to Figure 12 and Figure 13 and corresponding WARNING: when completing following log placement instructions. 1. Place front logs (#1 and #2) between front grate flange and main burner. Align notches on front logs with locator tabs in base. 2. Place middle log (#3) between front and rear loop of burner. Note: Do not place log on top of pilot assembly. 3. Place rear log (#4) on rear log shelf. Bottom flange of log must be placed between the log shelf and burner tube. 4. This step is optional for VFDR18LB10 log sets. Place front twig (#5) onto (#1) log and flat area on (#3) log. The bottom of the front twig is to be placed behind the grate tang that is second from the left. EMBER MATERIAL PLACEMENT ON BURNER 5. After all logs are positioned properly, apply Rockwool ember material to the front burner port area. To apply, carefully separate the ember material into small amounts no larger than "dime size" pieces. Fluffed up pieces one layer thick on top of the burner generally works best, and will provide the best e...
