H. Boiler Stacking (continued)
Figure 3: Stacking Boiler Attachment
Bracket Placement
Terminating individual boiler condensate
lines into common pipe prior to drain
disposal is permissible, providing common
pipe has sufficient flow capacity to handle
combined condensate volume of stackable
combination.
b. Gas Piping - Follow instructions in Section
VII “Gas Piping” of the manual for sizing
and installation of an individual boiler.
When common gas piping is sized, insure it
will have adequate capacity for combined
input (CFH gas flow) of the selected
stackable boiler combination.
c. Water Piping and Trim - Follow instructions
in Section VI “Water Piping and Trim” of
the manual for system piping and boiler
secondary piping selection/sizing based
on combined heating capacity and/or
gross output of the selected stackable
boiler combination
.
Follow instructions of
Section VI “Water Piping and Trim” for each
individual boiler trim installation.
d. Electrical - Follow instructions in Section VIII
“Electrical” of the manual to wire individual
boilers.
For side-wall venting individual model vent
terminals must terminate not closer than
12 inches horizontally and three (3) feet
vertically from each other in order to prevent
combustion air contamination. For vertical
through the roof venting, individual vertical
vent terminals, if level with each other,
must be spaced no closer than 12 inches
horizontally. If vertical terminals cannot
end in one plane, they must be spaced no
closer than three (3) feet horizontally.
If vertical vent terminals cannot end in one
plane, they must be spaced no closer then
three (3) feet horizontally.
Follow instructions in Section IV “Venting”
of the manual for specifics of individual
boiler vent termination. Follow instructions
in Section V “Condensate Disposal” for
each individual boiler flue gas condensate
line construction and condensate disposal.
Asphyxiation Hazard. No
common manifold venting is permitted. Each
boiler must have its own individual vent and
combustion air pipes and terminals.
