Outdoor Kitchen Ventilation
WARNING
Failure to adequately vent your
outdoor kitchen cavity could result in
an explosion or fire.
When building a gas griddle 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 griddle 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, 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.
