The Monument 4+2 Burner Gas Grill, model 35633, is built for buyers who want a lot of cooking space and extra features without moving immediately into premium gas-grill territory. Its headline numbers include six total burners, 72,000 BTU of total output, 700 square inches of total cooking area, an infrared side sear burner, and a ClearView lid.

I have been grilling since 1970, and one thing I have learned is that the biggest number on the control panel does not automatically make a grill better. Burner layout, usable grate space, temperature control, cleaning, replacement parts, warranty coverage, and whether you will actually use the extra features matter just as much.

This review is based on current manufacturer specifications and documented product information. I have not personally cooked on this exact Monument 35633, so I will not pretend that I have tested its heat distribution, fuel consumption, searing speed, or long-term durability.

Monument 35633 Specifications

Here are the important specifications Monument currently publishes for the 35633.

Important: The 72,000-BTU number is the combined output of the grill’s burner system. Do not read it as though each of the four main burners produces 18,000 BTU.

What Does “4+2 Burner” Mean?

The 4+2 description can be confusing at first. The Monument has four burners inside the main cooking chamber plus two side cooking stations.

• Four main burners control the primary grill.
• One side burner can handle a saucepan, beans, sauces, or other side dishes.
• One infrared side burner is designed for concentrated high-heat searing.

That layout is more useful than simply cramming six conventional burners underneath one cooking grate. Four independently controlled main burners give you room to create different heat zones while the two side burners perform separate jobs.

Why Four Main Burners Are Useful

Four main burners give you flexibility for direct and indirect cooking. You can run burners on one side while leaving the opposite side cooler, or divide the grill into several temperature zones when cooking different foods.

That can be particularly useful with chicken. Brown the chicken over direct heat, then move it toward a cooler part of the grill to finish without burning the outside. The same idea works for thick pork chops, sausages, and larger cuts that need time away from direct flame.

The Infrared Sear Burner Is One of the Main Attractions

If steak is high on your grilling list, the dedicated infrared side sear burner is one of the strongest reasons to consider this Monument.

An infrared burner creates concentrated radiant heat at a separate cooking station. Instead of taking over part of the main grill for searing, you can use the infrared side burner for browning and still keep the main cooking chamber available for other foods.

That can work well for a reverse-sear routine: cook a thick steak more gently in the main grill, then move it to the infrared side burner for the final crust.

The important word here is separate. Buyers who rarely cook steaks may get less value from this feature. Someone who regularly cooks ribeyes, strip steaks, chops, or other foods that benefit from a hard final sear is more likely to appreciate it.

How Much Cooking Space Does the Monument 4+2 Have?

The Monument provides 510 square inches on the primary cooking grate and another 190 square inches on the warming rack, giving it 700 square inches of advertised total cooking space.

I pay more attention to the 510-square-inch primary grate than the 700-square-inch headline figure. Warming racks are handy, but they are not the same as having another 190 square inches directly over the main burners.

Still, 510 square inches of primary grilling surface is substantial for ordinary family use. It also gives you enough space to set up separate direct and indirect cooking zones without immediately running out of room.

If you regularly cook for larger groups, the combination of the main grate, warming rack, side burner, and separate searing station is more meaningful than the BTU figure by itself.

Is the ClearView Glass Lid Useful?

Monument equips the 35633 with its ClearView glass window so you can look into the cooking chamber without opening the lid.

The idea makes sense. Every time you open a grill you release accumulated heat. Being able to look at food without lifting the lid can be handy, especially while roasting or cooking indirectly.

There is a tradeoff: any window located above grilling food will eventually collect grease, smoke residue, and splatter. If the window is one of the reasons you choose this grill, expect to make cleaning it part of normal grill maintenance.

Does 72,000 BTU Make the Monument Better?

No. BTU alone does not determine whether one gas grill cooks better than another.

BTU measures heat input. It does not tell you by itself how evenly a grill heats, how well the lid retains heat, how fast the cooking grate recovers after cold food is added, or how much fuel will be used during a normal cook.

Monument says the 35633 can reach 650°F in about 10 minutes. That is the manufacturer’s stated performance, not a result from my own testing.

The large total output is understandable when you remember that this grill has four main burners plus two separate side burners. A buyer should compare the entire burner layout rather than comparing 72,000 BTU against the main-burner rating of another grill and declaring a winner.

Monument 4+2 vs. Weber Spirit II E-310

The Weber Spirit II E-310 makes a useful comparison because it follows a very different design approach. The Monument emphasizes cooking stations and features, while the Spirit II uses three main burners and a simpler layout.

The table shows why BTU is a poor way to declare one grill better. The Monument’s 72,000-BTU figure includes its six-burner arrangement, while the Weber’s 30,000-BTU figure applies to its three main burners.

Choose the Monument if the larger cooking area, fourth main burner, regular side burner, and dedicated infrared searing station are features you expect to use.

Choose the Spirit II E-310 if you prefer a simpler three-burner grill and put more weight on Weber’s broad Spirit II warranty coverage than on side burners and a glass viewing window.

What I Like About the Monument 35633

1. Four Main Burners Give You Useful Heat Zones

Four burners across the main cooking chamber make it easier to create different temperature areas than on a smaller two-burner grill. That matters more to me than simply having another burner for bragging rights.

2. The Infrared Sear Burner Has a Specific Purpose

This is not merely another ordinary burner squeezed into the cabinet. Steak cooks can use the high-heat station separately while other food remains on the main grill.

3. The Regular Side Burner Can Keep the Kitchen Outside

A side burner can handle beans, sauce, vegetables, or another pan while you grill the main meal. It is most valuable for people who actually prepare complete meals outdoors.

4. The 510-Square-Inch Main Grate Is Generous

The primary grate is large enough to make the Monument worth considering for families and people who regularly cook for company.

5. Replacement Parts Matter

One thing buyers often overlook is whether replacement parts will be available after the grill has been used for several seasons. Monument maintains replacement-parts and support sections for its grills, which is worth checking before buying any outdoor cooker.

What I Would Think About Before Buying

The Warranty Is Not Eight Years on Everything

This deserves to be clear. Monument’s current warranty information provides a one-year warranty for defects in materials or workmanship and an eight-year limited warranty on stainless-steel burners against rust-through.

That does not mean every component has an eight-year warranty.

Rust Is Not Automatically a Warranty Claim

Monument’s warranty terms specifically exclude certain rust, oxidation, discoloration, and weather-related deterioration. That makes normal cleaning, keeping corrosive chemicals away from the grill, and protecting it from harsh weather important.

A Glass Window Adds Another Surface to Clean

I like being able to see food without lifting a lid, but I would not buy this grill solely because it has a window. If you hate cleaning grease and smoke residue from glass, consider the window a convenience with an extra maintenance job attached.

More Features Also Mean More Things You Need to Use

A dedicated searing station and side burner are valuable only if your cooking style calls for them. If you usually cook four hamburgers and two hot dogs, a simpler three-burner grill could make more sense.

Warranty and Long-Term Ownership

The most sensible way to judge long-term value is not to guess how many years a grill will last. Too much depends on climate, storage, cleaning, use, grease buildup, replacement parts, and whether the grill sits uncovered in rain and humidity.

Instead, look at what you can control:

• Keep the grease tray and firebox from accumulating heavy grease.
• Inspect burner openings periodically according to the owner’s manual.
• Keep the grill dry before covering it.
• Do not store corrosive chemicals or lawn products around the grill.
• Check propane hoses and connections before use.
• Use replacement components intended for the correct Monument model.

Monument also warns that insects can get into burner tubes. If flames become abnormal, weak, or uneven, shut the grill down and follow the manufacturer’s burner inspection and cleaning instructions rather than poking randomly into the gas system.

How to Reduce Flare-Ups on This Gas Grill

With any multi-burner gas grill, grease management matters. Fat dripping onto hot components can create brief flames; accumulated grease can create a much bigger problem.

Trim excessive fat, keep the grease system clean, and maintain a cooler zone where food can be moved if flames become aggressive. Never pour water onto a grease fire.

Who Should Buy the Monument 4+2 Burner Gas Grill?

Consider buying it if:

• You normally cook for a family or larger gathering.
• You want four independently controlled burners in the main cooking chamber.
• You cook steaks often enough to use a dedicated infrared sear burner.
• You use a saucepan or skillet outdoors and would benefit from a side burner.
• You want a 510-square-inch primary cooking grate.
• You like being able to view food through a lid window.
• You are willing to keep up with routine gas-grill cleaning and maintenance.

Consider skipping it if:

• You want the simplest possible three-burner gas grill.
• You rarely cook for more than two or three people.
• You would never use the side burner or infrared searing station.
• You place a higher priority on broad warranty coverage than additional cooking features.
• Your main goal is low-and-slow barbecue with strong wood-smoke flavor.

Final Verdict: Is the Monument 35633 Worth Considering?

Yes, for the right buyer. The Monument 35633 makes the most sense for someone who wants cooking flexibility: four main burners, a separate conventional side burner, an infrared searing station, a good-sized main grate, and a viewing window in one propane grill.

I would not buy it merely because the box says 72,000 BTU. That number is less important than how the grill is configured. The real attraction is the combination of four main cooking zones plus two specialized side burners.

The biggest tradeoff is warranty structure. The stainless-steel burners receive much longer coverage than the grill as a whole, so buyers should read Monument’s current warranty terms instead of assuming “eight-year warranty” applies to every part.

For buyers who will use the extra cooking stations, the Monument deserves a place on the shortlist. If those extras would sit unused, compare it with a simpler Weber Spirit II E-310 or another quality three-burner gas grill before deciding.

Frequently Asked Questions

How many burners does the Monument 35633 have?

The Monument 35633 has six burners in total: four main burners inside the grill, one conventional side burner, and one infrared side sear burner.

Is the Monument 35633 really a 72,000-BTU grill?

Yes. Monument lists 72,000 BTU as the total output of the full burner system. That total includes the grill’s four main burners plus its two side cooking burners, so it should not be compared directly with another grill’s main-burner rating alone.

How much cooking area does the Monument 4+2 have?

It has 510 square inches of primary cooking area plus a 190-square-inch warming rack, for 700 square inches of total advertised cooking area.

Does the Monument 35633 have an infrared burner?

Yes. It includes a dedicated infrared side sear burner intended for concentrated high-heat cooking, along with a separate conventional side burner.

What kind of cooking grates does it use?

The Monument 35633 uses porcelain-coated cast-iron cooking grates. Cast iron retains heat well, while the porcelain coating helps protect the underlying iron when properly maintained.

Does the Monument grill have a glass lid?

Yes. Monument’s ClearView lid includes a glass viewing window so food can be checked without lifting the lid. The window will still require regular cleaning as grease and cooking residue accumulate.

What is the warranty on the Monument 35633?

Monument currently states a one-year general warranty for defects in material or workmanship and an eight-year limited warranty on stainless-steel burners against rust-through. Warranty exclusions and purchase requirements apply, so buyers should check Monument’s current terms.

Is the Monument 35633 better than the Weber Spirit II E-310?

Neither is automatically better. The Monument provides four main burners, two additional side burners, more advertised cooking area, and an infrared sear station. The Weber Spirit II E-310 uses a simpler three-burner design and has broader 10-year warranty coverage. Choose according to the features you will actually use.
