prevent boiler water from back-feeding into the service water supply. Provision should also be made in
every boiler room for a convenient water supply which can be used to flush out the boiler and to clean
the boiler room floor.
5.4 Hot water boilers supply & return connections
Makeup water shall only be introduced to the boiler though the water inlet. The makeup water pipe shall
be provided with a check valve or a backflow preventer containing a check valve near the boiler and a
stop valve or cock between the check valve and the boiler or between the check valve and the return
piping system. Some jurisdictions may require installation of a backflow preventer in the feedwater
connection.
Stop valve(s) shall be placed in the supply and return pipe connections of a single hot water heating boiler
installation to permit draining the boiler without emptying the system. When stop valves over two (2”)
inches are used, they shall be of the outside and screw yoke rising spindle type, or of such other type as
to indicate at a distance by the position of its spindle or other operating mechanism whether it is closed
or open. The wheel may be carried either on the yoke or attached to the spindle. If the valve is of the
plug cock type, it shall be fitted with a slow opening mechanism and an indicating device, and the plug
shall be held in place by a guard or gland. The design pressure of all valves used in water headers should
equal or exceed the design pressure of the boilers they are attached to.
5.5 Drains
Unobstructed floor drains, properly located in the boiler room, will facilitate proper cleaning of the boiler
room. Floor drains that are used infrequently should have water poured into them periodically to prevent
the entrance of sewer gasses and odors. If there is a possibility of freezing and environmentally safe
antifreeze mixture should be used in the drain traps. Drains receiving blowdown water should be
connected to the sanitary sewer by way of an acceptable blowdown tank, separator, or air gap that will
allow the blowdown water to cool to at least 140°F and reduce the pressure to 5 PSIG or less.
5.6 Drain connections
The discharge piping shall be full size to the point of discharge. The minimum pressure rating of valves
and cocks used for drain purposes shall be at least equal to the pressure stamped on the boiler but in no
case less than 30 psi. The temperature rating of such valves and cocks shall not be less than 250°F.
The
condensate drain is located at the rear of the boiler below the flue connection. Slope the condensate
tubing down and away from the boiler into a drain or condensate neutralizing filter. Do not expose the
condensate line to freezing temperatures.
A condensate removal pump is required if boiler is below drain. When installing a condensate pump, select
one approved for use with condensing boilers and furnaces. The pump should have an overflow switch to
