Non-Priority – Boiler output is divided between
space heating and domestic hot water heating.
Delivery of domestic hot water can be reduced
during simultaneous space and domestic hot water
heating operations, depending on such factors as
boiler output, boiler over-sizing, number of space
heating zones calling for heat, and the ratio of
domestic hot water load to space heating load.

points of use.
water, place the Single-wall Indirect close to
points of use.
SYSTEM ZONE CONTROL
The Single-wall Indirect water heater must be installed
as a zone separate from the space heating system. The
domestic hot water zone’s piping and circulator must be
sized for a minimum flow rate with all zones in use and
a maximum flow rate with only the water heater in use.
For this reason, the preferred method of zone control is
with circulators.

circulators, the Single-wall Indirect should be
added as an additional zone with a circulator.

DOMESTIC HOT WATER PRIORITY
Two options are available, Priority and Non-Priority.
1.
Priority – Demand for space heating is
interrupted or postponed until the domestic hot
water demand is satisfied. This option provides
maximum delivery of domestic hot water. Priority
is recommended when:
interrupted or postponed until the domestic hot
water demand is satisfied. This option provides
maximum delivery of domestic hot water. Priority
is recommended when:
a)
Boiler net output is 100,000 Btu per hour or
less, or
less, or
b)
When boiler output required to satisfy
domestic hot water demand is at least 50%
of the boiler output required to satisfy space
heating demand, or
domestic hot water demand is at least 50%
of the boiler output required to satisfy space
heating demand, or
c)
When an interruption in space heating can
be tolerated during a long domestic hot
water draw.

water draw.
CAUTION
This water heater must be located in an area where
leakage of the tank, water line connections, or the
temperature and pressure relief valve will not result
in damage to the area adjacent to the water heater or
to lower floors of the structure. When such locations
cannot be avoided, a suitable drain pan must be
installed under the water heater. The drain pan depth
must be suitable for draining and collecting water,
and have a minimum length and width of at least four
(4) inches measured from the jacket of the water
heater. The drain pan, as described above, can be
purchased from your plumbing professional. The
drain pan must be piped to an adequate drain. The
piping must be at least ¾
