Dacor HDPR36 Installation Instruction - Dual-fuel Range - Page 18

Installation Requirements Gas Requirements Provide Adequate Gas Supply • Installation must follow local codes or, in their absence, the National Fuel Gas Code, ANSI Z223.1/NFPA 54. • The cooktop operates at a manifold pressure of 5 in. (13 cm) of water column for natural gas/natural gas at high altitude (NG-H) or 10 in. (25.4 cm) of water column for LP (propane)/LP at high altitude (LP-H). • Verify that the oven is right for the provided gas service. When verifying regulator function, inlet pressure must be at least 1 in. (2.5 cm) greater than the operating (manifold) pressure as given. • The regulator inlet receives a 3/4" gas line. (The range ships with a 1/2"-to-3/4" adapter on the regulator.) • The figures in the table at right are for reference only. MINIMUM GAS-SUPPLY PRESSURE REQUIREMENTS* (See the rating label-rear top-right corner of range- for exact measurements.) Gas Type Natural gas Min. Manifold Pressure 5" water column Min. Gas-Supply Pressure** 6" water column LP (propane) gas 10" water column 11" water column • The pressure regulator at the inlet of the cooktop *Gas-supply pressure for testing the regulator setting shall be at least 1" water column (249 Pa) above the specified manifold pressure; **Max gas-supply pressure, all models: 1/2 psi. manifold must stay in the supply line no matter the type of gas used. • Use only the range's regulator, which must be installed in the line between the cooktop gas inlet and the shut-off valve. • An external, manual shut-off valve must be installed between the gas inlet and the range. • Ensure the connectors are installed by a qualified installer. • For safety's sake, use only new flexible connectors. Special Gas Requirements (gas models sold in Massachusetts) • Gas suppliers recommend installing a UL-approved gas detector per manufacturer specifications. • The range must be installed by a plumber or gas fitter certified by the State of Massachusetts. • A T-handle, manual gas valve must be installed in the gas-supply line to the range. • If using a flexible gas connector, multiple lines must not be connected in series. 18 English
