MODULAR SYSTEMS
1.
General Guidelines
a. Read and follow all venting, combustion
air, water piping, gas piping and electrical
instructions contained in this manual unless
otherwise instructed in this section.
b. Design and installation of modular systems
should only be undertaken by skilled and
knowledgeable engineers and contractors.
c. Consult Local Building Codes, National Fuel
Gas Code, or NFPA 54/ANSI Z223.1 for
restrictions and instructions for modular boilers.
d. Refer to the Pre-Installation section for further
warnings, cautions, notices and instructions.
2.
Module Sizing
Consult factory for recommended number and size
of boilers for a given input.
3.
Venting
This section outlines venting requirements for
multiple boiler installations and should be used in
addition to the “VENTING” section earlier in this
manual.
a. Positive Pressure (Sidewall and Vertical) Venting
i. Positive pressure vent systems cannot be
manifolded together.
ii. Positive pressure systems can be piped
individually through a common vertical
or horizontal chase provided minimum
clearances to combustible materials are
maintained.
iii. Positive pressure systems can be piped
individually through a common vertical
chase so that a single roof penetration can be
made. Each vent termination must be one (1)
foot from all other terminations.
WARNING
DO NOT manifold vent components of multiple
boilers without converting to a negative
pressure venting arrangement.
b. Negative Pressure (Conventional) Venting
i. Refer to Figure 10 for an example of a
typical conventional venting arrangement
for modular boilers.
ii. Refer to National Fuel Gas Code to
determine required chimney diameter
and common venting diameter. Note that
combined input, lateral length and chimney
height affect vent diameter.
iii. Install a double acting barometric damper
with integral flue spillage interlock (as
