IM-PR 566442 1114 (Design Manual)
(CSA B214 Clause 4.6.2)
The installer shall ensure that the system
documentation and manufacturer’s operational
instructions are left near the primary heating
equipment or, if that is not practical, near the
main electrical distribution panel, in order for
service and maintenance personnel to have
access to the documentation and instructions.
NOTES:
(1) Examples of information that should be
provided in the documentation of the system
for hydronic space heating include
(a) a room-by-room heat loss calculation in
kW (Btu/h);
(b) the heat output of the heat-distribution
unit in kW (Btu/h);
(c) the system design water temperatures in
°C (°F);
(d) the pipe size in mm (nominal size NPS, in)
and total length of piping in m (ft); and
(e) the system head loss and flow rates in kPa
and L/s (psi and gpm).
(2) Examples of information that should be
provided in the documentation of the system
for radiant heating include
(a) a room-by-room heat loss calculation in
kW (Btu/h);
(b) the floor area in m
2
(ft
2
);

(d) the heat output density in W/m

(e) the radiant heating panel supply water
temperature in °C (°F);
(f) the pipe size in mm (nominal size NPS, in),
maximum spacing between the lengths
of piping in mm (in), and total length of
piping in m (ft);
(g) the minimum number of heating loops;
(h) the boiler supply water temperature in °C
(°F);
(i) the auxiliary heat required in kW (Btu/h);
(j) the RSI value in m

•K/W (R-value) of the
floor coverings;
(k) the RSI value m

•K/W (R-value) of the
insulation under and at the edges of the
radiant panel;
(I) the outdoor design temperature in °C (°F);
(m) the floor surface temperatures in °C (°F); and
(n) the system friction loss and flow rate in
kPa and L/s (psi and gpm).
(3) Additional information for documentation of
the system is presented in Figures A.1 and
A.2.
(4) Attempts should be made to instruct the
user in the safe and correct operation of the
system.

1.8 Piping
In most cases, the piping system uses primary
piping, secondary piping and panel piping to
distribute heat. Primary piping is the main piping
that supplies and returns fluid to the heat source.
Secondary piping is piping that is either directly
connected to the primary piping or originates off
manifolds fed by primary piping, but is not located
within a radiant panel. Panel piping is piping that is
used within the radiant panel, whether floor, wall or
ceiling.
