Outdoor Kitchen Ventilation
WARNING
Failure to adequately vent your
outdoor kitchen cavity could result in
an explosion or fire.
When building a gas grill into an outdoor kitchen, it is necessary to provide adequate ventilation for
the island cavity underneath. This is necessary for not only proper combustion, but also to prevent
a buildup of gas. While the amount of venting required for your island will vary due to the variety of
differing local codes, inner framework and design of an outdoor kitchen, the amount of gas
products installed and their locations, etc., all built in grill islands should be ventilated in some way.
Your local contractor and/or your local code authority can determine adequate ventilation for each
installation. Stainless Steel vent panels are available from your dealer to cover the island venting.
The following information is important to consider when adhering to your local code requirements.
LP/Propane Gas:
LP gas is heavier than air and will settle to the lowest levels of the outdoor
kitchen. It is imperative to provide adequate cross ventilation for the areas where gas can
accumulate at these lower levels of the island cavity. Should the Propane cylinder be located in the
outdoor kitchen itself, a plenum wall is required to separate the gas source from the other areas of
the outdoor kitchen (picture shown in owner’s manual), and both the cabinets containing the gas
appliances and the gas tank should be ventilated appropriately. If a plenum wall is undesirable,
Blaze offers a Propane tank drawer as an alternative.
NG/Natural Gas:
Natural gas is lighter than air and will rise to the highest levels of the outdoor
kitchen. It is imperative to provide adequate cross ventilation for the areas where gas can
accumulate at these higher levels of the island cavity.
