Finned copper tube gas boilers & water heaters – Boiler Manual

F
F
To operate properly and safely this boiler/water heater requires a
continuous supply of air for combustion. NEVER store objects on
or around the boiler/water heater!
Combustion air contaminated with fluorocarbons or
other halogenated compounds such as cleaning
solvents and refrigerants will result in the formation
of acids in the combustion chamber. These acids will
cause premature failure of the boiler/water heater
voiding the warranty!
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 fireplace, 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.
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!
All Air From Inside The Building
If the Dominator is to be located in a confined space the minimum
clearances listed in Table 1 must be maintained between it and any
combustible construction. When installed in a confined 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
2
/kW
based on the total input rating of ALL gas utilization equipment in
the confined area. Each opening must be no less than 100 in
2
, 64,516
mm
2
in size. The upper opening must be within 12 in, 305 mm of,
but not less than
3 in
,
76 mm
from, the top of the enclosure. The
bottom opening must be within
12 in
,
305 mm
of, but not less than
3 in
,
76 mm
from, the bottom of the enclosure.
