b. Each Phantom boiler is factory packaged with
two (2) Stacking Boiler Attachment Brackets
(P/N 101679-01) and the bracket mounting
hardware [six (6) self-drilling hex washer head
plated #8 x ½” long screws]. Locate and remove
the brackets and the hardware. The Stacking
Boiler Attachments Bracket has three 7/32”
diameter holes punched in a triangular pattern.
See Figure 3 “Stacking Boiler Attachment
Bracket Placement”.
c. Phantom boiler left and right side panels have a
series of dimples at panel top and bottom. These
dimples are positioning dimples for Stacking
Boiler Attachment Bracket mounting screws.
Side panel bottom positioning dimples are evenly
spaced from boiler front and back, while side

f. Install the third Stacking Boiler Attachment
Bracket to secure top and bottom boiler left side

guidelines:
a. Venting - Top and bottom boilers must have their
individual vent piping and vent terminals.
WARNING
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.
Follow instructions in Section IV “Venting”
vent termination. Follow instructions in Section
V “Condensate Disposal” for each individual
condensate disposal. Terminating individual
boiler condensate lines into common pipe prior
