Preface<\/strong><\/p>\n

<\/p>\n

This is the fifth edition of CSA B214, Installation code for hydronic heating systems<\/em>. It supersedes the previous editions, published in 2016, 2012, 2007, and 2001.<\/p>\n

<\/p>\n

The main changes from the previous edition are as follows:<\/p>\n

<\/p>\n

a) added requirements for use of potable water as a hydronic fluid (Clause 4.2.5.1);<\/p>\n

<\/p>\n

b) clarified recycling requirements for prevention of stagnation (Clause 4.2.5.2);<\/p>\n

<\/p>\n

c) added requirement for pipe insulation in unconditioned spaces (Clause 8.2);<\/p>\n

<\/p>\n

d) removed allowance for PVC pipes and tubing, and PVC fittings;<\/p>\n

<\/p>\n

e) clarified that metal\/plastic pipes refer to PEX-AL-PEX and PERT-AL-PERT composite pipes (Clauses 9.2.3 and 9.2.4);<\/p>\n

<\/p>\n

f) clarified that polypropylene random copolymer refers to PP-R & PP-RCT pipes and tubing (Clauses 9.2.5);<\/p>\n

<\/p>\n

g) added requirements for flexible pre-insulated plastic piping and installation of non-metallic piping in return air plenums (Clauses 9.2.7 and 9.2.8);<\/p>\n

<\/p>\n

h) added requirements for support of larger sizes PEX and PERT tubing as per ASTM F876 (Clause 9.4.1);<\/p>\n

<\/p>\n

i) added requirements for support of non-metallic pipe and tubing in support channels, and vertical run support for non-metallic pipe and tubing in support channels (Clauses 9.4.2 and 9.4.7);<\/p>\n

<\/p>\n

j) added requirements for pipe insulation, pipe sleeves, thermal expansion and contraction, and contact with building materials (Clauses 9.5 to 9.8);<\/p>\n

<\/p>\n

k) added requirements for PERT-AL-PERT composite pipe fittings, and plastic-to-metal connections (Clauses 10.4 and 10.10);<\/p>\n

<\/p>\n

l) removed restriction on use for compression valves for isolation purposes;<\/p>\n

<\/p>\n

m) added requirements for manifolds (Clause 11.3);<\/p>\n

<\/p>\n

n) changed high-temperature requirement limit for radiant floor heating panels (Clause 12.2.2);<\/p>\n

<\/p>\n

o) clarified requirements for makeup supply connection (Clause 12.5.4);<\/p>\n

<\/p>\n

p) added exception for differential pressure regulation (Clause 12.5.5.1);<\/p>\n

<\/p>\n

q) clarified requirements for air space above insulation (Clause 14.5.3.2);<\/p>\n

<\/p>\n

r) added space limits for air space behind insulation (Clause 14.6.2);<\/p>\n

<\/p>\n

s) added requirements for types of tube fasteners (Clause 17.4.2); and<\/p>\n

<\/p>\n

t) added requirements for heat exchanger and piping and materials (Clause 18.4.1).<\/p>\n

<\/p>\n

This Code has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1 General<\/p>\n

<\/p>\n

This Code sets out the minimum provisions for the installation, extension, alteration, and renewal of hydronic heating systems.<\/p>\n

<\/p>\n

1.2 Inclusions<\/p>\n

<\/p>\n

This Code applies to open and closed hydronic heating systems. These systems include<\/p>\n

<\/p>\n

a) hydronic space heating;<\/p>\n

<\/p>\n

b) radiant heating (wall, floor, and ceiling);<\/p>\n

<\/p>\n

c) convectors;<\/p>\n

<\/p>\n

d) fan coils;<\/p>\n

<\/p>\n

e) combination potable-water-heating and space-heating (combo) systems;<\/p>\n

<\/p>\n

f) integrated mechanical systems;<\/p>\n

<\/p>\n

g) indirect-fired domestic-water heating;<\/p>\n

<\/p>\n

h) pool and spa heating;<\/p>\n

<\/p>\n

i) snow and ice melt systems; and<\/p>\n

<\/p>\n

j) other auxiliary systems.<\/p>\n

<\/p>\n

1.3 Interchangeable terms<\/p>\n

<\/p>\n

The terms pipe and piping, as well as tube and tubing, are used interchangeably in this Code, unless otherwise stated.<\/p>\n

<\/p>\n

1.4 Terminology<\/p>\n

<\/p>\n

In this Code, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Code.<\/p>\n

<\/p>\n

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n

<\/p>\n

1.5 Units of measure<\/p>\n

<\/p>\n

The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only.<\/p>\n","protected":false},"excerpt":{"rendered":"
