This guide collects them for the DH, EE, DEE, AH/1E, FT, PT, GT, GPT, D, TDB and TDH series and separates operator work from service network work. ## Key takeaways - Groen builds tilting gas kettles (DH, TDH), tilting electric kettles (EE, DEE, TDB), a stationary self-contained gas line (AH/1E) and direct steam kettles (FT, PT, GT, GPT, D). - Each manual requires installation by personnel qualified in gas, electricity or plumbing, done to local code. - Check the jacket water level in the gauge glass every day, and never heat an empty kettle. - Test the pressure relief valve daily, and inspect fittings and valves at least once every 90 days as the FT, PT, GT and GPT manual directs. - Clean after every use and sanitize with a 200 parts per million chlorine solution, then rinse the sanitizer off. ## The Groen kettle lines Groen's steam-jacketed kettles differ by heat source and mounting. The DH operator manual describes a floor-mounted, tilting kettle with a self-contained gas-heated steam source in 20, 40, 60 and 80 gallon capacities, tilted with a hand crank. The EE manual covers floor-mounted tilting kettles with self-contained electrically heated steam supplies in 20, 40, 60, 80 and 100 gallon capacities, and our list adds the crank tilt, floor mounted, electric DEE-4 series in 20, 40 and 60 gallons with Classic, Advanced or Cook2Temp™ controls. The AH/1E manual covers stationary, non-tilting kettles with a self-contained gas steam source, emptied through a 2 inch tangent draw-off. Direct steam models take steam from a remote source. The FT, PT, GT and GPT manual covers FT and PT deep kettles with 2/3 jackets and GT and GPT fully jacketed kettles; FT and GT stand on tubular legs and PT and GPT on a pedestal base. Our list also carries the crank tilt floor models D-20, D-40 and D-60 on pedestal bases with 2/3 jackets, plus hand tilt table and cabinet mounted direct steam kettles rated at 55 PSI with 304 or 316 stainless liners. For counter work, the TDB and TDBC are table top tilting kettles with a self-contained electrically heated steam supply in 20, 24, 40 and 48 quart capacities, and the TDH and TDHC are the gas-heated equivalents. The TDB tilts by handle and the TDBC by hand wheel crank, and the pouring height accepts pans up to four inches high on a table top. ## Installation requirements Every Groen manual requires installation by qualified personnel. The DH manual states the unit must be installed by personnel qualified to work with gas, electricity and plumbing, in accordance with applicable codes, and the AH/1E manual directs Canadian installations to the CAN/CGA B149 installation codes and the Canadian Electrical Code, CSA C22.1 Part 1. Gas and electrical connections must be made by a qualified, licensed installer to local code. The manuals give these clearance figures: - DH floor kettles: 6 inches minimum from combustible walls at each side and 10 inches at the rear, 0 inches at the sides from non-combustible walls, with 6, 10 and 12 inches recommended. - AH/1E: six inches minimum at the sides and six inches between the draft diverter and the wall. - TDH table top kettles: 1 inch minimum at the left and rear, 0 inches at the right, with 12 to 16 inches recommended at the right for servicing. - FT, PT, GT and GPT: clearance at the sides and rear as the specification drawings require, with the pedestal or legs anchored securely to the floor and a bead of silicone sealant at the flange. ## Supplies, levelling and steam piping Level the kettle by turning the bullet or flange feet; the DH manual says to use a spirit level on the bar rim. The gas models pipe to the service main with a 1/2 inch line on the DH and TDH and a 3/4 inch IPS line on the AH/1E, and take 115 VAC service: 5 amps on the DH, 15 amps on the AH/1E and 1 amp on the TDH. The DH and TDH manuals call for a vent hood and exhaust fan, with no direct connection between the vent duct and the kettle flue. The EE takes the power shown on its electrical information plate, ships ready for three-phase operation, and receives supply through a 1-1/4 inch conduit opening with a watertight 90 degree elbow recommended. TDB and TDBC units ship wired for 208V or 480V three-phase, with wiring diagrams for single-phase conversion, and the base fastens to the work surface through four 3/8 inch-16 NC threaded couplings with a silicone caulk bead around the perimeter. On direct steam kettles the supply line must be as large as the steam inlet fitting, a globe valve is required on the steam inlet, and a strainer, steam trap and check valve are needed on the condensate outlet, which runs to the boiler return line or a drain. A pressure reducing valve goes in the supply line near the kettle when steam pressure exceeds the nameplate maximum. On self-contained models the safety valve elbow must point downward, and the installer confirms the jacket water level before start-up: between the gauge glass markers on the DH, above the midpoint on the EE, and at or near the middle of the sight glass on the TDB and TDH. ## Start-up and daily operation The start-up tests use a little water: 1 to 2 gallons in the DH, about six inches of water plus a full draw-off test in the EE, 1 to 2 quarts in the TDB and at least one inch in the TDH, heated at the highest setting until it boils. The FT, PT, GT and GPT manual has you open the steam inlet valve, inspect the fittings for leaks once the water boils, and pull the safety valve chain to test it. Daily checks come first in every operation section. Confirm the jacket water level in the gauge glass each day on DH and EE kettles; the EE manual adds a cold check that the pressure gauge shows 20 to 30 inches of vacuum. The FT, PT, GT and GPT manual says to bleed entrapped air and test the safety valve once a day while there is still pressure in the jacket. Controls vary by line. DH Classic models set heat from 1 to 10 on a temperature knob; Advanced models set 1.0 to 10.0, with LOW TEMP, MANUAL and HIGH TEMP buttons defaulting to 2.0, 5.0 and 7.0, a timer from 1 minute to 10 hours, and a ready alarm of three beeps within 20 degrees of set point. Cook2Temp™ models set the unit between 100°F and 287°F, default 183°F, or an AUTO C2T product temperature between 100°F and 230°F, with the unit temperature set 100°F above it. The EE uses a thermostat dial and indicator light, and on the AH/1E a pressure limit switch turns the burner off at 27 PSI and relights it at 22 PSI. The EE and AH/1E manuals give kettle temperatures of 150°F to approximately 270°F, the DH manual 100°F to approximately 287°F, and the TDB and TDH manuals 150°F to 295°F. Direct steam kettles operate from five PSI to the nameplate maximum, normally 25 PSI. The DH and TDH gas supplies shut off automatically when the kettle is tilted, and the TDB has a tilt cut-off switch. Product leaves through the tangent draw-off: a 2 inch compression disc valve with a stainless strainer on the EE, and a 2 inch OD 316 stainless disc with a 1/4 inch perforated strainer on the FT, PT, GT and GPT, with a 3 inch draw-off optional. ## Safety rules the manuals stress The DH, EE, TDB and TDH manuals all warn not to heat an empty kettle, because excessive steam pressure could develop. Every manual says to keep liquids a minimum of 2 to 3 inches (5 to 8 cm) below the kettle rim to allow clearance for stirring, boiling and safe transfer. A low water indicator light or cutoff disables the gas valve or heating elements until the jacket is refilled. When tilting to transfer product, the manuals give these rules: - Wear a protective oven mitt and apron. - Use a container deep enough to minimize splashing, on a stable, flat surface as close to the kettle as possible. - Stand to the side of the kettle, not in the pour path, and pour slowly. - Return the kettle upright after the container is filled, and do not overfill the container. - Never tilt the kettle with the cover or a basket insert in place, and never stand on or apply weight to the kettle front or pouring lip. ## Cleaning and operator maintenance Clean food contact surfaces as soon as possible after use, preferably while the kettle is warm, and at least once every 12 hours in continuous use. Scrape and flush out residues, wash with a hot detergent solution, disassemble the tangent draw-off and brush the draw-off pipe and each valve part, then rinse and drain. Do not mix parts between draw-off assemblies; they are not interchangeable. Use brushes, sponges, cloth, plastic or rubber scrapers or plastic wool only; steel wool and metal tools scratch the surface, which makes it harder to clean and gives bacteria places to grow. Sanitize with a solution supplying 200 parts per million available chlorine, rinse the sanitizer off, and sanitize just before use. The FT, PT, GT and GPT, EE and TDH manuals say never to leave a chlorine sanitizer on stainless steel longer than 30 minutes, while the AH/1E manual sets the limit at 10 minutes. For mineral deposits or film, the manuals point to Groen Delimer/Descaler (Part Number 114800) or Lime-Away from Ecolab, following the manufacturer's directions, then rinse and drain. Keep water and solutions out of the controls and never clean with a high-pressure hose. Operator maintenance is mostly inspection. Test the safety valve each day: the FT, PT, GT and GPT manual says to pull the chain until steam is released and let it snap shut, and to stop using the kettle and contact a qualified Groen service representative if the lever does not activate, there is no discharge, or the valve leaks. At least once every 90 days, inspect fittings and valves for signs of damage or wear, and keep the maintenance log at the back of the manual up to date. ## Troubleshooting an operator may do The FT, PT, GT and GPT troubleshooting table lists the checks an operator may make. If the kettle will not heat, confirm that the steam inlet valve is open, the steam supply line is turned on, the condensate return valve is open, and the boiler supplies steam above five PSI. If the safety valve leaks a small amount of steam, lift the lever briefly all the way up, with substantial pressure in the jacket, to blow the valve clean, then let it snap back down. For pipe fitting leaks, check that the fitting is tight. The same table marks other work for a Groen Authorized Service Agent only: blockages in the steam supply or condensate return lines, steam trap operation, replacement of a defective safety valve with one rated at the same pressures, and packing replacement. The TDB manual says to recheck power supply connections first if the unit does not run, then contact the local Certified Service Agency, and the EE manual sends a unit that does not operate as described to the local Groen Certified Service Agency. ## Service through Groen's authorized network Repairs belong to Groen's authorized service network. The FT, PT, GT and GPT manual says to order replacement parts through your Authorized Service Agent, supplying the model designation, serial number, part description, part number, quantity and, where applicable, voltage and phase. Any mechanical or electrical change must be approved by Groen's engineering department. For questions about a specific model in our list, ask Norpex. ## Common questions ### How much clearance does a Groen DH kettle need? The DH manual gives minimums of 6 inches from combustible walls at each side and 10 inches at the rear, with 6, 10 and 12 inches recommended. From non-combustible walls the side minimums drop to 0 inches. ### How often should the safety valve be tested? Every day. The FT, PT, GT and GPT manual says to pull the valve chain with pressure in the jacket until steam escapes, then let it snap shut, and to contact a qualified Groen service representative if it leaks or does not discharge. ### Can the kettle run with low jacket water? No. A low water indicator light or cutoff disables the gas valve or heating elements until the jacket is refilled, and the DH, EE, TDB and TDH manuals all warn against heating an empty kettle. ### What temperatures do Groen kettles reach? The EE and AH/1E manuals give 150°F to approximately 270°F, the DH manual 100°F to approximately 287°F, and the TDB and TDH manuals 150°F to 295°F. Direct steam kettles run from five PSI to the nameplate maximum, normally 25 PSI. ### How do I remove hard water film from the kettle? Clean the kettle thoroughly, then use a deliming agent such as Groen Delimer/Descaler (Part Number 114800) or Lime-Away from Ecolab, following the manufacturer's directions, and rinse and drain before further use. ## Related guides - [Soup Season: Choosing Soup Kettles, Warmers and Steam Tables](https://norpex.ca/guides/soup-season-kettles-and-warmers) - [Restaurant Equipment Checklist: What to Buy to Open in Canada](https://norpex.ca/guides/restaurant-equipment-checklist) ## Shop the catalogue - [Steam Kettles](https://norpex.ca/products/steam-kettles) - [Tilting Skillets & Braising Pans](https://norpex.ca/products/tilting-skillets-braising-pans)
