Short answer: this guide compares five Thor Kitchen 36-inch gas ranges we sell as single products. Thor's own site lists more 36-inch gas ranges than these five. All five here have six burners and a convection oven, run on 120 V power, and come in a natural gas or a propane version. Where they differ is the simmer, the strongest burner, the oven size and the broiler.
- LRG3601U: two 18,000 BTU burners and a 6.0 cu ft oven. Thor lists no simmer burner; its smallest burners are 9,000 BTU.
- HRG3618U: two dual burners that simmer at 650 BTU, a 16,500 BTU infrared broiler and a 22,000 BTU bake burner. Its 5.2 cu ft oven is the smallest of the five.
- ARG36 (Contemporary Professional): one 18,000 BTU burner and a 6.0 cu ft oven. Thor lists no simmer burner; its smallest burners are 9,000 BTU.
- XRG36E (X Series): a 22,000 BTU dual burner that simmers at 1,000 BTU, a 6.0 cu ft oven, and the same 16,500 BTU infrared broiler and 22,000 BTU bake burner ratings as the HRG3618U.
- SRG3601 (S Series): two 18,000 BTU burners, a 3,500 BTU simmer burner and a 6.0 cu ft oven.

How to choose
- Low heat. If you hold sauces or melt chocolate, look at the simmer. The HRG3618U simmers at 650 BTU on both of its 15,000 BTU dual burners. The XRG36E simmers at 1,000 BTU on its 22,000 BTU dual burner. The SRG3601 has a dedicated 3,500 BTU simmer burner. Thor lists no simmer for the LRG3601U or the ARG36, whose smallest burners are 9,000 BTU.
- High heat. The XRG36E's dual burner is rated 22,000 BTU, the highest of the five. The LRG3601U and the SRG3601 each have two 18,000 BTU burners. The HRG3618U and the ARG36 have one each.
- Oven and broiler. Four of the five list a 6.0 cu ft oven; the HRG3618U lists 5.2 cu ft. The HRG3618U and the XRG36E pair a 22,000 BTU bake burner with a 16,500 BTU infrared broiler. The other three have an 18,500 BTU bake burner, with a 13,500 BTU broil burner on the ARG36 and SRG3601 and a 10,000 BTU tube broiler on the LRG3601U.
- The opening you have. Thor's spec sheets list a 36" wide cutout for the ARG36, XRG36E and SRG3601, and 36-1/8" for the LRG3601U and HRG3618U. Cutout depths run from 24" to 24-13/16". Measure your opening before you choose, and see the install notes below.
Installing a Thor 36-inch gas range
- Indoors only. Thor says: "THOR Kitchen ranges are intended for indoor use only." For an outdoor kitchen, read our Thor gas grill guide instead.
- Use a professional. Thor says: "It is strongly recommended to get your range installed by a qualified professional, especially for gas or dual fuel models." Have a licensed gas installer connect the range, leak-test the connection before first use, and do any propane conversion.
- Cutout and fit. Check your opening against the cutout in the table, then confirm it in the installation manual that ships with your range. Go by that manual for the distances to side cabinets, the wall behind and anything above the cooktop.
- Power. Thor lists 120 V for all five. The XRG36E spec sheet calls for a "15 Amp Dedicated Circuit". The HRG3618U spec sheet lists a 15 A breaker in one table and "15 or 20 A" in another. Have an electrician set up the circuit your installation manual calls for.
- Island installs. If the range will sit in an island, Thor's spec sheets list an island trim for two of these models: the ITHRG3618U for the HRG3618U and the ITXRGD36E for the XRG36E. For the other three, check the installation manual and call us before you plan an island.
- Ventilation. Thor says freestanding and slide-in models "can be paired with THOR Kitchen range hoods or other compatible external ventilation systems." Choose the hood with your installer, following the manual and your local code.
- Local rules. Check with your local building department about permits and inspection before you start.

Questions buyers ask
Which of these five has the biggest oven?
Four tie at 6.0 cu ft: the LRG3601U, ARG36, XRG36E and SRG3601. The HRG3618U has 5.2 cu ft. Thor's ARG36 product page table shows 6.1 cu ft, but its spec sheet and feature list both say 6.0.
Can I run one on propane?
Yes. For the LRG3601U, HRG3618U and ARG36, choose natural gas or propane on our product page. The XRG36E and SRG3601 have their own propane listings: the XRG36E propane range and the SRG3601LP. The table lists the LP kit part numbers on Thor's spec sheets. One caution: Thor's LRG3601U spec sheet names kit LPKLRG3601U, but its product page names LPKLRG2401U, so call us to confirm the kit before you order one.
Do I need a 240-volt outlet?
No. Thor lists 120 V for all five. Your electrician should still set up the circuit the installation manual calls for.
Will one of these ranges fit the opening my old range left?
Measure first. Thor's spec sheets list a 36" wide cutout for the ARG36, XRG36E and SRG3601, and 36-1/8" for the LRG3601U and HRG3618U, with cutout depths from 24" to 24-13/16". The table above has each full cutout. Have your installer confirm the fit against the manual.
Do any come in black or white?
Two of these five do. Thor makes the LRG3601U in black (LRG3601UB) and white (LRG3601UW), and the ARG36 in matte black (ARG36B) and white (ARG36W). We list the LRG3601UB, LRG3601UW, ARG36B and ARG36W, and a propane version of each.
Do any have a griddle?
None of the five has a built-in griddle. Thor's spec sheets list the RG1022 griddle as an accessory, not included, for the LRG3601U, HRG3618U and XRG36E, and the RG1032 cast iron range griddle for the HRG3618U. The ARG36 and SRG3601 spec sheets list no griddle. Ask us before you order one for a specific range.
What warranty comes with a Thor range?
Thor sets the warranty. Thor's warranty page, last updated August 24, 2026, describes a 2-year warranty covering parts and labor for Thor Kitchen appliances, with listed exceptions. Check it for the current terms for your model before you buy.
