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.

1.Circulators – With space heating zones using circulators, the Single-wall Indirect should be added as an additional zone with a circulator.

2.Zone Valves – Select a valve with a low-pressure drop to assure adequate flow through the water heater.

3.Hybrid – The space heating zone can be zoned using zone valves and the Single-wall Indirect zoned 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:

a)Boiler net output is 100,000 Btu per hour 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

c)When an interruption in space heating can be tolerated during a long domestic hot water draw.

2.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.

COMPONENT LOCATION

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” in diameter and pitched for proper drainage.

Appliance Location

1.Boiler Location – Locate the Single-wall Indirect as close to the boiler as practical.

2.Fixture Locations – For fastest delivery of hot water, place the Single-wall Indirect close to points of use.
