5. Never vent boiler into enclosed space� Always vent to
the outside� Never vent to another room or inside a
building�
6. Verify adequate air supply for complete combustion�
7. Relief valve automatically lifts open when system
pressure exceeds 30 psi� Before installing relief valve
read manufacturer’s instructions� Pipe relief valve to a
safe location� Check with authorities having jurisdiction�
8. Consider system total water volume, temperature,

4.2 Prior To Installing The Boiler
• Verify you have selected right size boiler with proper
capacity� AHRI rating of boiler selected should be greater
than or equal to calculated peak heating load (heat loss)
for building or area(s) served by boiler and associated
hot water heating systems� Use heat loss calculations
based on approved methods� See Table 6, page 27�

in a building of unusually tight construction, air for
combustion and room ventilation must be obtained
from outdoors or from spaces freely communicating
with the outdoors� A permanent opening or openings
having a total free area of not less than 1 square

appliances shall be provided� Ducts may be used to
convey make-up air from the outdoors and shall have

that freely communicate with the outdoors� One of the
following methods must be used to provide adequate
air for ventilation and combustion�
A� When directly communicating with the outdoors,
each opening shall have a minimum free area of 1
square inch per 4,000 Btu per hour of total input
rating of all equipment in the enclosure� See Figure

B� When communicating with the outdoors by means
of vertical ducts, each opening shall have a
minimum free area 1 square inch per 4,000 Btu per
hour of total input rating of all appliances in the
enclosed space� See Figure #4�
C� If horizontal ducts are used, each opening shall
have a minimum free area 1 square inch per 2,000
Btu per hour total input rating of all appliances in
the enclosed space� See Figure #5�
D� When ducts are used, they shall be of the same
cross sectional area as the free area of the area of
the openings to which they connect� The minimum
dimension of rectangular air ducts shall not be less
than 3 inches�
