such recommendations. If none is offered, the following informa-
tion gives suggested locations.
When used for high limit service, the control should be in-
stalled in the riser close to the boiler, or in a boiler tapping that
is near the top or hottest section of the boiler. If the boiler is also
used to heat domestic hot water, make sure that the high limit
control is not located in the section of the boiler that contains the
heat exchanger or piping for domestic hot water.
