FIGURE23 : Wiring Diagram for DGAA and DGAH Models Unitary ProductsGroup GAS PIPING INSTALLATION AND CHECKING OF GAS LINE Gas Supply piping must be sized in accordance with the recommendations contained in National Fuel Gas Code (ANSIZ223.1, NFPA-54) unless local codes or regulations state oth erwise. Matedals used and pipe sizing for U.S. manufactured homes must comply with requirements contained in Manufactured Homes Al19.1, Recreational Vehicles Al19.2 and H.U.D. Title 24, Section 3280.705 and any local or state codes. NOTE: The gas line inlet on the gas valve is 1/2-14 N.ET The gas line may be installed through the furnace floor or furnace side to the gas valve. F& CAUTION To install gas line and to connect it to the gas valve, care must be taken to hold gas valve firmly to prevent misalignment of the bumer orifice, or to damage gas valve which could result in improper heating, explosion, fire or asphyxiation. DO NOT USE EXCESSIVE PIPE SEALANT ON PIPE JOINTS. Pipe sealant, metal chips or other foreign material that could be deposited in the inlet of the gas valve, when gas pipe is installed or carried through the gas piping into the gas valve inlet after installation, may cause the gas valve to malfunction and could result in possible improper heating, explosion, fire or asphyxiation. Also, pipe sealant must be resistant to Propane gas. Where regulations require, a main shut-off valve shaft be installed externally of furnace casing. After piping has been installed, turn gas on and check aft connections with a leak detector or soap solution. Never use open flame to test for gas leaks as fire or explosion could occur. Do not test the fuel system at more than 14" HZC. after furnace has been connected to fuel line. Such testing could void the warranty. Any test run above 14" WC. may damage furnace control valve which could cause an explosion, fire or asphyxiation. I CAUTION! If the gas input to the furnace is too great because of excessive gas pressure, wrong size orifice, high altitude, etc., the burnerflame will be sooty a...
