Installation
Combustion Air Requirements
The ENERGY KING Wood/Coal Boiler must have a minimum supply
of 70 cubic feet of air per minute.
All fuel-burning appliances must have air (oxygen) for proper combustion. The incomplete
combustion that takes place when a solid-fuel appliance is “air-starved” causes carbon monoxide
(CO) production in quantities that can be dangerous inside a building. Combustion air from outside
may need to be brought in to prevent “air starvation”. Although an outside air source is strongly
recommended for all installations, it may be necessary if:
•
The heating appliance does not draw steadily, smells, experiences smoke roll-
out, burns poorly, or backdrafts, whether or not there is combustion present.
•
Any of the above symptoms are alleviated by opening a window slightly on a
calm day.
•
The house is equipped with a well-sealed vapor barrier and tight fitting windows
and/or has any powered devices which exhaust house air, such as clothes
dryers.
•
A ventilation system is installed in the house.
Consult a qualified boiler installer to analyze whether the air supply in your installation environment
is adequate.
Failure to provide adequate combustion air can
lead to increased carbon monoxide production
and increased emissions of combustion gases
into the building, which may cause death or
serious injury.
