INSTALLATION REQUIREMENTS
The installation of this indirect-fired storage water heater must
conform to the following:
1. Local, state, provincial, and national codes, laws, regulations
and ordinances.
2. National Electrical Code (NEC).
3. National Plumbing Code (NPC).
4. Building Officials and Code Administrators International
(BOCA).
In any case where instructions in this manual conflict with the
above, let those codes take precedence.
The location of this indirect-fired storage water heater should be
made in consideration of the following:
1. Install indoors where not subjected to freezing temperatures or
physical damage.
2. Install as close to boiler as practical, to minimize piping con-
nections pressure drop and heat loss.
3. For system service convenience, do not install too close to the
boiler or other objects.
4. Install near a floor drain if possible, to prevent possible proper-
ty damage due to relief valve discharge or equipment leakage.
A drain pan is most suitable for protecting the surrounding
area.
The boiler used to supply hot water to the heater must meet these
requirements:
1. In some jurisdictions the boiler’s operating pressure must be
limited to 30 psig by a safety relief valve.
2. The boiler’s input rating must be within the heater’s recom-
mended sizing guide specifications. Too low an input rating
may cause excessive condensation in the boiler. Too high an
input rating may cause a boiler short cycling condition. Either
of these conditions could be detrimental to the life and perfor-
mance of the system.
PIPING REQUIREMENTS
TEMPERATURE AND PRESSURE RELIEF VALVE
1. Use only the Watts model or equivalent specified in the chart
below. The rating of each valve meets the absorption capaci-
ty of only the model of heater for which it is specified.
2. Must be installed in the run of a tee located in domestic hot
water outlet in heater, unless a dedicated installation port is
provided. No shutoff valves are permitted to be piped between
the relief valve and the heater tank, nor on the T & P discharge
line. (See Fig. 4)
3. Must be positioned to discharge downward, with the dis-
charge line within 6” of the floor line and directed towards a
drain or drain pan, if possible. The discharge line must not be
excessively long or reduced in size, be subject to freezing, or
be directly connected to a drain.
BOILER PIPING CONNECTIONS
1. General piping recommendations (See Fig. 4)
a) Install unions and shutoff valves for servicing conve-
nience.
b) Use 1” nominal minimum piping size and keep number
of elbows and overall piping length to a minimum to
insure the proper water flow rate to the heater coil.
c) Pipe the supply from the boiler into the coil inlet con-
nection, located at the top of the coil.
d) Pipe the return to the boiler from the coil outlet con-
nection, located at the bottom of the coil. Install a tee
with a drain at the coil connection, with a shutoff valve,
to aid in manual air purging.
2. Circulator zoning recommendations (See Fig. 2)
a) The preferred location of the circulator pumps for each
zone is on the boiler supply, with the expansion tank
between the boiler and the circulators.
b) A flow check valve must be installed on each zone,
preferably at the outlet side of each circulator pump, to
prevent water flow to other zones when they are not
demanding flow.
3. Zone valve zoning recommendations (See Fig. 3)
a) The preferred location of the circulator pump is on the
boiler supply, with the expansion tank between the
boiler and the circulator.
b) Use zone valves with low pressure drop specifications,
particularly on the water heater zone. A 1” zone valve
is recommended.
Figure 2. Typical piping for circulator zoning
Figure 3. Typical piping for zone valve zoning

PIPING REQUIREMENTS FOR
DOMESTIC WATER CONNECTIONS (See Fig. 4)
1. General piping recommendations
a) Install unions and shutoff valves for servicing
convenience.
b) If the heater is replacing a tankless coil in the
boiler, do not plug tube outlets in the tankless coil
after disconnecting from plumbing.
2. Domestic cold water inlet
a) Install a tee with a drain on the tank cold water
inlet nipple.
b) Install the cold water supply piping into the tee on
the tank cold water inlet.
c) If a back flow preventer or check valve is used on
the cold water supply, then a thermal expansion
tank must be installed between the tank and this
device.
d) If excessive water supply pressure is evident, a
pressure reducing valve on the supply line may
be necessary to prevent relief valve discharge.
Check local codes.
3. Domestic hot water outlet
a) On heater sizes which do not have a dedicated
port for the T & P valve, a tee must be installed
onto the tank hot water outlet nipple for the instal-
lation of the T & P valve. See T & P valve instal-
lation requirements on page 3.
b) Install the hot water supply piping into the branch
of the tee (if used) on the tank hot water outlet.
c) A thermal loop can be arranged on this piping to
prevent thermal siphon action of the hot water
when not in use.
d) A mixing valve can be installed on hot water pip-
ing which feeds areas where high temperature
water is not desired. This will allow for higher
temperature water to be delivered to areas where
it is demanded without endangering the user at
the lower temperature fixtures.

WIRING REQUIREMENTS
1. General wiring requirements
a) Wiring must conform to National Electrical Code
in U.S.A., C.S.A. C22.1 Canadian Electrical Code
Part 1 in Canada, and any other national, provin-
cial, state, or local code requirements having
jurisdiction.
b) All line voltage wiring must be a minimum 18
gage.
c) A separate service switch for the water heater
electrical circuit is recommended. This switch
must not turn off the boiler or other components in
the heating system.
d) IMPORTANT NOTE:
All wire connections to “T-T” or “A-A” termi-
nals on boiler control must be from an isolat-
ed circuit which does not carry voltage from
an external source. Any component which
does not have isolated end switches must not
be used unless a relay is added with the dry
contacts wired to these terminals.

2. Circulator zoning wiring (See Fig. 5, 6)
a) Components must be wired to ensure that only the
circulator for each zone is powered on a demand
for supply water from that zone.
b) Multi-zone switching relays are available as an
alternative to individual zone relays to simplify the
wiring and provide priority on domestic hot water
demand.
3. Zone valve zoning wiring (See Fig. 7, 8)
a) Components must be wired to ensure that only the
zone valve for each zone is powered on a demand
for supply water from zone, and that the circulator
is powered on a demand from any zone.
b) The transformer used to power the zone valves
must be sized for the load of all the zone valves in
system.

OPERATING PROCEDURES
1. Filling the heater tank
a) Make sure all drain valves on the cold or hot water supply
piping are closed.
b) Open the nearest hot water faucet and any shutoff valves
on the domestic hot water supply piping from the tank out-
let.
c) Open the shutoff valve on the cold water supply piping to
the tank inlet.
d) Allow the cold water supply to fill the tank by leaving the hot
water faucet open until all air is purged from the tank and
piping, and a steady flow of water is observed from the
faucet.
e) Close the hot water faucet, but leave all piping shutoff
valves open.
f) Any other hot water faucets fed by this heater may be
opened to purge air from their supply piping, and then shut
off after a steady flow of water is observed from the faucet.
2. Filling the heater coil
a) Attach a hose to the drain valve on the coil outlet (return to
boiler). Place the end of the hose into a drain or bucket in a
manner that will prevent potentially hot water from spraying
on any persons in the area.
b) If a shutoff valve has been installed between the drain valve
and the boiler return, keep this valve shut at this time.
c) Open the shutoff valve (and on a zone valve system, man-
ually open zone valve) on the supply piping from the boiler.
d) Open the drain valve on the coil outlet to purge the air from
the coil. When a steady flow of water is observed from the
drain, then open the shutoff valve on the return piping to the
boiler. Additional air from the return piping should purge
itself at this time. Close the drain valve when the steady flow
of water is again observed.
e) Remove the hose from the drain valve. Leave the drain
valve closed. Leave all shutoff valves open. Return zone
valve to automatic operation.
f) Purge air from remaining zones, if necessary. Check boiler
gauge pressure reading afterward to be appropriate. 15 psi
is normal for most installations.
3. Operating the heater
a) After the system has been manually purged of its air, and
all components (valves, vents, controllers) have been set
properly, the boiler can be started. NEVER operate this
heater until this has been done.
b) The maximum setting for the boiler water supply to the
heater coil is 220° F.
c) The maximum setting for the heater tank temperature con-
trol is 160° F. Unless there is specific demand for very high
temperature domestic hot water, the control setting should
be set at the lower end of the temperature range of adjust-
ment to reduce the risk of scalding injury. Some areas
require that the tank control setting be below 130°.
d) When the temperature of the water in the heater tank is
below the setting on the tank control, the boiler and circu-
lator should start. If a zone valve is used for this zone, it
should open at this time. When the temperature of the
water in the heater tank reaches the temperature setting on
the tank control, the boiler and circulator should turn off
(and zone valve, if used, should close). If other zones for
heating are in demand, this would also run boiler and cir-
culator(s). Cycling of the boiler on high limit is not abnor-
mal, particularly if only one zone is in demand. On initial
startup with a cold tank, a considerable amount of time may
be required for the tank to reach desired temperature.
Maintenance recommendations:
1. Temperature and pressure relief valve operation check
a) Once a year, the T & P valve must be manually operated to
ensure safe and proper operation.
b) Make sure that the discharge line from the T & P valve is
directed towards a drain or some collection method, and
will not spray onto any person.
c) Use lever on T & P valve to open. A steady discharge of hot
water should be noticed. After releasing this lever, the
T & P valve should close and fully shut off this flow.
d) If the T & P valve does not function properly, it must be
replaced with the same model or its equivalent. DO NOT
plug the outlet of this valve if a dripping condition occurs.
2. Flushing the heater tank
a) Once a year, or if a persistent discolored water condition
exists, the heater tank should be manually flushed to
remove possible sediment accumulation.
b) Turn off the boiler before draining the heater tank.
c) Attach a hose to the drain valve on the cold water supply to
the tank. Place the end of the hose into a drain or bucket in
a manner that will prevent potentially hot water from spray-
ing on any persons in the area.
d) Close the shutoff valve on the cold water supply to the tank.
e) Open the drain valve on the cold water supply and drain
down tank completely. Open the T & P valve or a nearby
faucet to break vacuum on drain.
f) After the heater tank is drained, close the drain valve and
reopen the cold water supply valve to refill the tank. The
introduction of water into the tank should act to stir up sed-
iment accumulations which can then be drained through
the drain valve. Go back through the draining and filling
process until clean water is observed passing out the drain.
g) Once clear water conditions are accomplished, make sure
the heater tank and all domestic hot water supply piping is
purged of air and discolored water. Leave the drain closed,
check for the T & P valve to be properly seated, and make
sure all shutoff valves for the hot and cold water supply are
left open. The boiler can then be returned to operation.
