All Air From Inside The Building
If the Dominator is to be located in a confi ned space
the minimum clearances listed in Table 1 must be
maintained between it and any combustible construction.
When installed in a confi ned space
without the intake
air option
, Figures 1, 2 & 3, two permanent openings
communicating with an additional room(s) are required.
The combined volume of these spaces must have
sufficient volume to meet the combustion air
requirements of all gas utilization equipment. Fireplaces,
wood stoves or any type of exhaust fan must be
considered when making this determination. Each
opening must have a minimum free area of
1 in
2
/1000
Btu/hr,
2200 mm

based on the total input rating of
ALL gas utilization equipment in the confi ned area. Each
opening must be no less than

CAUTION: If the boiler/water heater is operated while
the building is under construction it MUST be
protected from wood, concrete, sheet rock and other
types of dust. Failure to properly protect the unit
from construction dust will damage the unit voiding
the warranty!
Buildings will require the installation of a fresh air duct
or other means of providing make-up air if the intake
air option isn't used. Any building utilizing other gas
burning appliances, a fi replace, wood stove or any type
of exhaust fan must be checked for adequate
combustion air when all of these devices are in
operation at one time. Sizing of an outside air duct must
be done to meet the requirements of all such devices.
WARNING: Never operate the Dominator in an
environment subjected to a negative pressure
unless the air intake is connected to the
outdoors. Failure to comply with this warning can
result in excessive levels of carbon monoxide
causing severe personal injury or death!
