The Infinity ignition system is designed to be more robust than the standard ignition system. The upgraded ignition was implemented when Weber started offering a full 10 year warranty on every single component as the older style ignition system often failed after 3-5 years. A flip-up motor and separate spit and fork weber q storage compartment have also been integrated into the model. You get three burners with 39,000 BTU input plus the dedicated sear-zone burner for an extra 13,000 BTU. We will run through the main differences as you go through the lineup. We’ve picked the cheaper enamel models and the non-natural-gas versions.
But this model is still available for purchase at big-box stores like Home Depot and Lowe’s. We still think it’s a great grill with clever design features. For one thing, this grill has an externally weber q mounted propane tank, which is easier to install and replace than traditional, under-grill tanks . And this type of tank also frees up the area under the grill for storage of tools and other items.
In theory, you can buy any of the three-burner grills as a four-burner. It is like the SP-E-335, except it’s larger and adds a burner for 48,000 BTU output. Because of availability issues, we bought both the S-335 and the SP-E-335 . The difference is the stainless exterior, better grates, and stainless Flavorizer bars.
The grates in S-315, S-335, S-435, and SX-335 gas grills are 7 mm thick stainless steel rods. MHP or Modern Home Products have been making gas grills longer than anyone. Yes, they are old school, but this gas grill is built like a tank.
There are fewer choices, limited availability, and the model numbers can be confusing. Weber discontinued some of their models earlier this year due to portable bbq component issues. Find a spot to place it in that you are happy with and stick with it. They do well with heat retention but not for portability issues.
