The manual begins with a welcome and congratulations message, emphasizing Thor Kitchen's commitment to providing the best cooking experience and customer satisfaction. It advises users to read the manual thoroughly before installation for proper usage and maintenance. A crucial note instructs users to inspect the product for shipping damage upon arrival and to contact Thor Kitchen directly for assistance rather than returning the product to the seller. Contact information for support, including a phone number and email address, is prominently displayed.
The "Gas Rangetop Installation" section highlights that installation must be performed by a qualified appliance installer, service company, or gas supplier. It stresses the importance of reading the entire manual before installation and saving it for future reference. The appliance must be installed in accordance with National Electrical Codes, as well as all state, municipal, and local codes, ensuring correct voltage, frequency, and amperage from a dedicated, grounded circuit breaker or time delay fuse. Thor Kitchen gas rangetops are manufactured for use with natural gas or liquid propane gas (LP).
Throughout the guide, specific types of highlighted information are used to ensure safe operation. "IMPORTANT NOTE" indicates critical information requiring attention, "CAUTION" warns of situations that could lead to minor injury or product damage if instructions are not followed, and "WARNING" signifies hazards that may cause serious injury or death if precautions are not ignored.
A dedicated "WARNING" section addresses what to do if gas is smelled, advising against lighting appliances, touching electrical switches, using phones in the building, and instead, immediately calling the gas supplier or local fire department.
Further important instructions include that installation and service must be performed by qualified professionals, and warranty service by an authorized Thor Kitchen service partner. Users are warned not to store or use flammable vapors and liquids near the appliance. A ventilation hood is recommended for use with the rangetop. Specific requirements for installations in Massachusetts are also detailed, including the need for licensed professionals and approved gas shut-off valves and flexible connectors.
The manual includes general warnings about children not playing with packaging material, the importance of removing staples from the carton, and carefully reading all instructions to prevent burns. It also mentions California's Proposition 65, explaining that burning gas can expose users to low levels of listed substances due to incomplete combustion, and suggests opening a window or using a ventilating hood to minimize exposure. Proper installation and grounding by a qualified technician are reiterated as essential.
Users are advised against repairing or replacing any part of the appliance unless specifically recommended by the owner's manual or customer service department, emphasizing that repairs should only be done by authorized Thor Kitchen technicians to reduce risks.
Additional warnings cover storing flammable materials near surface burners, storing explosives, and the dangers of touching hot surface burners or surrounding areas after use. It explicitly states that the appliance should never be used as a space heater due to the risk of carbon monoxide poisoning.
The "Installation Instructions" section reiterates the responsibility of the technician for proper installation and grounding, noting that improper installations are not covered under warranty. Leak testing according to manufacturer instructions and local codes is required.
For "GAS CONNECTIONS," specific notices for Massachusetts appliance dealers are provided. The manual details requirements for connecting the rangetop to the supply line with a 1/2-inch black iron pipe or a certified flexible stove connector, and the use of approved sealing compound. It warns against applying direct pressure to the rangetop manifold pipe when tightening connections and advises holding the pressure regulator with a wrench to prevent twisting and dangerous leaks. Installation for manufactured (mobile) homes must conform to specific federal and CSA standards.
The manual also covers installations for recreational vehicles and park trailers, requiring adherence to relevant codes and standards. It instructs users to check all piping connections for leaks using a soap solution and to repair any leaks found. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during pressure testing.
The "GAS LINE SHUT-OFF VALVE" subsection provides detailed steps for installing a manual gas line shut-off valve in an easily accessible location, applying Teflon tape or thread compound to connections, and installing flare union adapters to the regulator and shut-off valve. Leak checks with a leak detector or soapy water are again emphasized.
"INSTALLATION / CLEARANCES" specifies that all units must be installed according to minimum rear and side wall clearances and vertical clearances above the cooking top, as stated on the serial plate. It also warns that surrounding wall coverings, countertops, and cabinets must withstand temperatures up to 200 °F/93 °C.
"GAS RANGETOP SPECIFICATIONS" provides detailed clearance requirements for installation, both with and without a range hood, and for island installations. It specifies minimum side clearances from combustible surfaces, maximum wall cabinet depths, and minimum heights for wall cabinets above the cooking surface. A "CAUTION" note warns against placing items of interest to children in cabinets above the cooktop to prevent injuries from climbing.
For installations with a range hood, it specifies a minimum clearance of 0” for the back wall with a backsplash or high shelf, and a 30” (76.2 cm) minimum clearance between the rangetop and the bottom of the range hood. The range hood must exhaust outside, and a recommended CFM of 600 for a 30” rangetop is given for best smoke elimination. Downdraft ventilation systems are not to be used.
"ELECTRICAL REQUIREMENTS" states that the rangetop requires a 110-volt, 50/60 Hz electrical supply for the ignition system, with a 3-prong grounding plug. The power outlet must be within 36”/30 cm from the right side of the rangetop and accessible after installation. It stresses that the rangetop must be properly grounded and not grounded to any gas line or pipe.
The manual includes product dimensions and back layouts for each model (HRT3003U, HRT3618U, HRT4806U), showing the location of the regulator and power supply box.
The "RANGETOP INSTALLATION" section provides step-by-step instructions for installing the rangetop, including removing packaging, setting aside burners and grates, gently sliding the unit into the cut-out, ensuring gas and electrical connections are properly installed, and then sliding the rangetop back to the wall. Finally, it instructs to install all burners, burner caps, and grates.
"CONNECTING GAS TO RANGE TOP" explains that the rangetop is designed to operate at specific water column pressures for natural gas or propane gas (LPG). It details the conversion process for LPG, which must be done by a qualified installer. Correct operating pressures for natural gas (4-5” water column) and LP gas (10-12” water column) are provided, along with the requirement for the inlet pressure to be at least 1” more than the operating manifold pressure. The pressure regulator must remain in the supply line. It specifies the maximum length for flexible metal appliance connectors and advises shutting off the main gas supply valve before hook-up and relighting pilots on other gas appliances afterward. The use of a CSA certified flexible metal appliance connector is recommended, and pipe joint compound resistant to NG gases should be used on all male external pipe threads. Steps for installing a service manual gas shut-off valve and connecting a flexible gas line are included.
"GUIDELINES FOR USING RANGE TOP BURNERS" offers advice on using the dual burners' low turn-down setting (SIM) for delicate cooking tasks. It warns against leaving the rangetop unattended, allowing flames to extend beyond cookware, and touching hot handles. Users are instructed to keep handles out of the way, take care when deep-frying, and ensure all burner parts are properly in place and clean to prevent dangerous flames or blockages. It also advises checking for regular blue flames without yellow tipping.
"SURFACE BURNER IGNITION" describes how to light the top burners by pushing and turning the control knob counterclockwise to "HI," listening for the electric spark, and then adjusting the heat. A note warns that all burner igniters will spark when one burner is turned to "HI," and advises against disassembling or cleaning burners while another is on or touching hot components during sparking.
For models with a griddle, "Before Using the Griddle" provides instructions for initial cleaning, rinsing, and drying the griddle. It mentions a stainless-steel cover that must be removed before use and instructs on positioning the grease tray. "Use of the griddle" details how to operate the griddle, including pushing and turning the control knob to the desired temperature, preheating for at least 15 minutes (indicated by the griddle light), noting that the griddle light cycles on and off like an oven cycling light, and explaining that the front of the griddle is for warming while the back is the cooking area. It also mentions adding butter or cooking oil.
"TROUBLESHOOTING TIPS" provides a table of common symptoms, possible causes, and solutions. Symptoms include burners not lighting (wet, dirty, or misaligned parts/igniters), top burner not staying lit (failed thermocouple), flames not burning all around the burner cap (dirty or misaligned parts), very large and yellow burner flames (clogged bezel ports, improper positioning, wrong gas type, faulty regulator), igniters sparking but burners not igniting (gas shut-off valve in "OFF" position), burner flame going out at low setting (low gas pressure, obstructed air intake holes), flames suddenly gone out (draft or spill), and no ignition spark (dead batteries or failed ignition module). Solutions range from cleaning and reassembling parts to contacting the gas company or replacing the thermocouple/regulator. A "CAUTION" note explains how to manually light burners if there is no spark ignition. The sound of "cracking" or "popping" from the rangetop is identified as normal metal heating and cooling.
The "WARRANTY AND SERVICE" section outlines the warranty terms. Thor Group disclaims all express warranties except for those stated. The warranty applies to products purchased and located in the United States and covers 2-year parts and labor. For commercial usage, it's a 6-month parts and labor warranty. Implied warranties terminate upon expiration of the limited warranty. Thor Group will pay for repair labor and replacement parts for defects in material and workmanship, provided service is by an authorized agency during normal working hours. It also provides contact information for service inquiries.
Thor Group will not pay for service to instruct on use, correct house wiring, replace fuses, or correct installation.
