Gas supply
Thermador gas and dual-fuel ranges require a dedicated gas supply line with a shutoff valve accessible without moving the range. The gas line must be properly sized for the range’s total BTU load — a Pro Grand 48″ with 120,000+ BTU needs a larger supply line than a 30″ model. Use a flexible gas connector (yellow-coated stainless steel) of the correct diameter. Gas connections must be tested for leaks with a combustible gas detector after installation.
Electrical requirements
Gas ranges: dedicated 120V, 15-amp outlet for ignition and controls. Dual-fuel ranges: dedicated 240V, 40-50 amp circuit for the electric oven (plus gas supply for the cooktop). The outlet location is specified in the installation manual — typically behind the range, low on the wall.
Ventilation
A vent hood rated for the range’s BTU output is required. Minimum CFM = total BTU ÷ 100. Pro Grand 48″: minimum 1,200 CFM. Standard 36″: minimum 600 CFM. The hood must be at least as wide as the range. Duct routing should minimize bends and length for maximum extraction efficiency.
Clearances
Professional series ranges require a 10″ backguard or backsplash modification (the cooktop sits higher than standard). Pro Harmony models sit flush with standard 36″ countertops — no backguard needed. Maintain the specified clearance to combustible surfaces on all sides.
Anti-tip bracket
All Thermador ranges must be secured with the included anti-tip bracket — this prevents the range from tipping forward if weight is applied to an open oven door. This is a safety requirement, not optional.
