These pieces have become a critical part of the commercial kitchen, protecting the health and comfort of employees while reducing demands on the HVAC system. Most are designed to be used with a specific model of cooking equipment, so be sure you consult the owner's manual for your range or charbroiler to find the right riser. With that knowledge, choosing one of these for your kitchen is a snap. However, if you don't have access to that information or want further direction, read on for more tips.
These are fairly simple pieces, essentially just tall boxes that affix to your cooking equipment. Because they must match up with those pieces, the first and most important consideration is found in the dimensions of the unit.
The first determining factor is the width of both your range and the riser you're considering. The two numbers should match up, ensuring the entire range surface or charbroiler grate is well vented.
Following width is height, which can be a critical determining factor for a number of reasons. The majority of the flue risers listed here will be at least two feet tall. The higher the slotted vent cap is located, the closer to your ventilation hood it will exhaust the heat and gases.
Typically, the closer you can get those two, the better the unit will work to remove heat and vapors from the operator area; also, more air can be pulled over top of the range, meaning there is more air to fuel the burner flames.
In certain circumstances, it may be beneficial to have a shorter riser, which can allow for more varied use of the area above that unit. In that case, we offer products that are no more than a few inches tall, clearing up plenty of wall space. However, it's important to note that you shouldn't mount bulky, solid items above the vent cap, as this can break up the flow of the heat and gases to the hood, and deflect those out into your kitchen.
If you want to user larger items like mixers or microwaves above your range, or if you simply need a convenient place to stash things like spice jars and hot mitts while you work, opt for a tall unit with shelves. These are specifically designed to provide stability and storage without interrupting the flow of air through the flue riser. Be sure you check the weight capacity of the shelves before you buy if you plan to store heavy items. We offer units that come with one or two shelves, providing you with the storage space you need.
If you buy a unit without shelves and later decide to add them, or if you want to mount something else above your range, it's important that you only install those items in spaces designated by the manufacturer. Drilling holes or screws in the flue can interrupt the flow of air, decreasing efficiency of the unit and cooking equipment.
Shelves are available in both solid and tubular designs to fit the needs of your kitchen. Solid shelves are preferable if you'll be storing small items like spice jars and utensils, or bulky ones like mixers. Tubular shelves will provide adequate support for things like hot mitts and pans. These may be preferable in hot kitchens, as they will be less of an obstruction to warm air rising toward the hood than solid shelves.
Be aware that certain models in this category are designed for a specific type of equipment, so take care to purchase one that will fit the cooker you need to vent. There are units built to accommodate ranges and charbroilers here.
- Range flue risers are the most prevalent type and will account for most of the units that don't specify equipment. These are designed to sit on the back edge of the top of the range, with a gap between the front of the riser and the cooking surface that allows for the intake of air.
- Charbroiler flue risers are constructed to accommodate a very different type of cooking. Rather than mounting on the top of the unit, they fit into the back of it, enabling them to pull smoke and other gases from the cooking area, and to bring air in to feed the flames.
