Outdoor Kitchen Ventilation
WARNING
Failure to adequately vent your
outdoor kitchen cavity could result in
an explosion or fire.
When building a gas appliance 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 applications/ 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. If 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 on page 24), 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.
The following diagram shows a variety of examples of venting locations and configurations for an
outdoor kitchen. These are not the only possible options for venting but instead simply some
examples of the more common configurations found. Notice the middle set of vents being
positioned lower on the island cavity for LP gas.
