INTRODUCTION

The Raypak indirect water heater uses heat from a boiler to heat domestic water. The heat is transferred to the
water by a coil heat exchanger inside of the tank. The indirect storage tank stores the energy from the boiler for
use later. With the excellent thermal insulation in the Raypak water heater, the boiler turns on and off less often.
To maintain energy efficiency the stainless steel tank is fully insulated with 2 inches of rigid foam. The Raypak in­direct water heater is an efficient means of heating water.

This indirect water heater has all stainless steel construction. The stainless steel tank is fully welded, pickled and
passivated. The stainless steel resists corrosion assuring a long service life.

SAFETY WARNINGS

WARNING: Improper installation, adjustment,

alteration, service or maintenance can cause serious
injury or property damage. Refer to this manual. For
assistance or additional information, consult a
qualified installer or service agency.

CAUTION: The recommended water temperature

for normal residential use is 120°F. The control
temperature setting does not always reflect the
outlet water temperature, which could occasionally
exceed 120°F. The variation in outlet temperature
could be based on factors including but not limited to
usage patterns and type of installation. Test your
water at the tap nearest to the indirect water heater.

WARNING: Hotter water increases the risk of scald

injury. Before adjusting the water temperature
setting, read this instruction manual. Temperatures
at which injury occurs vary with the person’s age and
the length of exposure.

The slower reaction time of children, elderly, and
physically or mentally-challenged persons increases
the scalding hazard to them. It is recommended that
lower water temperatures be used where these
exposure hazards exist. Such households may
require a temperature setting less than 120°F to
prevent accidental contact with hot water.

To lower water temperature, use point-of-use
temperature limiting devices.

Single-Wall Heat Exchanger

Freeze Protection

This Indirect fired water heater uses a single-wall heat
exchanger. In order for this water heater to meet the re-

uirements of the Uniform Plumbing Code, the following

q
requirements must be met.

1. The boiler water pressure must be limited to 30 PSI.

An approved 30 PSI relief valve must be installed
in the boiler loop.

2. The boiler heat transfer medium must be either

potable water or use fluid additives that have a tox­icity rating of Class 1.

3. Bear a label on the system with the Wording “Cau-

tion” followed by:

a. The heat transfer medium must be water or

other nontoxic fluid having a toxic rating of
Class 1 as listed in clinical Toxicology of Com­mercial Products, 5th ed.

b. The pressure of the heat-transfer medium must

be limited to a maximum of thirty (30) psig
(207kPa) by an approved safety or relief valve.

The water heater and water lines must be protected
from exposure to freezing temperatures. Freezing tem-

eratures can cause damage to this indirect water

p
heater. The unit should be located indoors.

If the water heater is to remain idle for an extended pe­riod of time, the power and water to the boiler system
should be turned off to conserve energy and prevent a
build-up of dangerous hydrogen gas.

The water heater and piping should be drained if they
might be subjected to freezing temperatures.

After a long shut-down period, the water heater’s oper­ation and controls should be checked by qualified serv­ice personnel. Make certain the water heater is
completely filled again before placing it in operation.

Component Location

or best results, the indirect water heater should be in

F
a central location close to the boiler. This will minimize
heat loss in the boiler piping and reduce wait times for
hot water at the point of use. The indirect water heater
must be protected from freezing temperatures.

Anode Rods

The use of anode rods is not required for this unit. The
all-stainless steel construction of this tanks minimizes
corrosion.

Boiler and Circulator Sizing

The ratings published in this manual for your Raypak
indirect water heater can be obtained through proper
selection of boiler output and circulator capacity. See
the performance data in Table C.

To determine the appropriate circulator for your system,
follow these three steps:

A tempering valve may be required by local jurisdiction
to protect the user from scalding. Raypak recommends
the use of a tempering valve with this indirect water

eater. The tempering valve limits the water tempera-

h
ture at the point of use.

If local municipal codes require a backflow preventer,
an expansion tank will be required. The expansion tank
will prevent pressure build-up inside of the indirect water
heater and associated piping. The expansion tank must
be installed in the domestic water piping close to the
tank. No shutoff valve is allowed between the expansion
tank and the indirect water heater.

All water connections made to this heater should be
sealed with thread tape or pipe dope. It is important to
use two pipe wrenches when tightening connections to
this tank. One wrench should be used to support the
tank fitting from rotating; the other wrench will be used
to rotate and tighten the plumbing fitting. It is recom­mended to use shutoff valves on this tank for servicing.
The shutoff valves should not isolate the relief valve or
expansion tank from the indirect water heater. The inlet
of the heater should be piped with a drain connection
for servicing the heater.

1. Calculate the pressure drop of all straight pipe and

fittings on the supply and return at the desired flow
rate.

2. Add the pressure drop from Step 1 to the pressure

drop through the indirect water heater coil (see
Table C for friction loss) to obtain a total pressure
drop.

3. Select a circulator pump that will provide adequate

flow at the total pressure drop. A pump performance
curve should accompany every circulator pump.

Temperature & Pressure Relief
Valve

This water heater requires a temperature and pressure
relief valve. The T&P relief valve is supplied by the in­staller. This relief valve is required for safe operation of
the unit to protect from excessive temperatures and
pressures. A discharge pipe should be installed to the
relief valve. This discharge piping should terminate in a
safe location. This discharge piping must comply with
local and national plumbing codes. The piping must be
rated for 120ºF and 150 PSI.

Several piping diagrams are shown below depicting var­ious installation variations. Use these diagrams (Figs. 3
& 4) to help piping the indirect water heater.

This unit is not supplied with a separate drain fitting. It
is recomended that one be added to the inlet piping. Fig­ure 2 depicts the drain valve installation.

Controls

A Control system is required for this indirect water
heater to function correctly. Some possible control
schemes are explained below. The particular control

cheme will depend upon the specific installation.

s

This indirect water heater can be connected to any Ray­pak boiler that is equipped with a VERSA control. The
VERSA control is pre-configured to handle an indirect
storage water heater. The VERSA control can also be
configured to give priority to the domestic hot water or
to space heating. To connect the unit to a VERSA­equipped boiler, read the VERSA IC Installation & Op­erating Manual, Cat. 5000.72.

For the VERSA system to function properly, a 10K Ohm
thermistor needs to be installed into the tank aquastat
location, per Fig. 5.

Fig. 5: 10K Ohm Thermistor Installation

The indirect water heater can be controlled by an aqua­stat. The aquastat measures the domestic water tem­perature inside the tank. When more heat is required,
the aquastat will turn on the pump to circulate boiler
water through the indirect water heater.

To install the aquastat into the heater, see Fig. 6.

igure 7 is a controls diagram for a boiler that is always

F
on, maintaining hot water in the boiler loop. The aquas-

at turns on a circulator to induce boiler water flow

t
through the indirect water heater.

Fig. 7: Boiler Maintaining 180ºF

Figure 8 depicts wiring the indirect water heater to a
cold-start boiler system using a Honeywell RS845. In
this type of system, the boiler does not run unless there
is a call for heat in one of the zones of the system. When
connecting to a cold-start boiler, always remember that
in principle an indirect water heater operates as another
heating zone. The difference is that when the indirect
water heater calls for heat, the indirect water heater cir­culator must start rather than opening a zone valve; the
system circulator stays off, and the boiler must light to
reach Operating Temperature.

START UP

Relief Valve

new combination temperature and pressure (T&P) re-

A
lief valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water Sup­ply Systems, ANSI Z21.22, is supplied by the installer.
It must be installed in the opening provided and marked
for the purpose on the water heater. No valve of any
type should be installed between the relief valve and the
tank. Local codes shall govern the installation of relief
valves.

The pressure rating of the relief valve must not exceed
150 PSI, or the maximum working pressure of the water
heater as marked on the rating plate.

The BTUH rating of the relief valve must equal or ex­ceed the BTUH input of the water heater as marked on
its rating plate.

Position the outlet of the relief valve above a suitable
open drain to eliminate potential water damage. Piping
used must be of a type approved for hot water distribu­tion.

The discharge line must be no smaller than the outlet
of the valve and must pitch downward from the valve to
allow complete gravity drainage of the relief valve and
discharge line.

The end of the discharge line should not be threaded or
concealed, and must be protected from freezing. No
valve of any type, restriction, or reducer coupling may
be installed in the discharge line.

Checking Circulator

Check that the circulator or zone valve operates when
there is a call for heat. When a call for heat is initiated,
water should begin to flow through the indirect water
heater’s coil.

Set the Thermostat to the
Desired Temperature

For normal water heating installations, Raypak recom­mends an operating temperature of 120ºF or 49ºC.
Other temperatures may be required by the particular
installation. To minimize burns and scalding, Raypak
recommends that the water temperature be verified at
the point of use (see Verify the Water Temperature
below).

For VERSA-equipped Raypak boilers, the indirect water
heater’s setpoint is controlled by the boiler and the
10k Ohm thermistor installed in the water heater’s ther­mal well. To adjust the water heater setpoint, please
refer to the equipped boiler, read the VERSA IC Instal­lation & Operating Manual, Cat. 5000.72.

For installations with an aquastat control, the tempera­ture is adjusted at the aquastat control located on the
tank thermowell. To adjust the setpoint temp, rotate the
dial on the aquastat to the desired setpoint.

Verify the Boiler Functionality

Purging the System

Purge the system of air and check for leaks at all of the
connections.

Flushing the System

Flush the system completely. It is important to clear any
debris and residues from inside the piping and tank be­fore the water heater will be put to use by the customer.
To flush the system, open one of the hot water valves
at the point of use after the water heater. Allow enough
water to flow through the tank to change the water vol­ume at least two times.

When a call for heat is initiated, the boiler should come
on and begin heating. The boiler should also shut off
when the tank has reached its setpoint. If the boiler does
not heat, please check that water circulator is function­ing and that the wiring is correct.

Verify the Water Temperature

Raypak recommends that the water temp be verified at
the point of use. First, let the indirect water heater come
to temperature. The water heater has reached its set­point when the boiler heating water has stopped flowing
through the heat exchanger. To verify the water temp,
open the shutoff valve at the point of use. Let the water
run for several minutes until the temperature has stabi­lized. Measure this stabilized water temperature.

Any claim for warranty assistance must be made promptly. Raypak reserves the right to deny any warranty claim filed more than ninety (90) days after an
incident covered by this Limited Warranty occurs. First, determine if your indirect water heater is “in-warranty” (that is, within the applicable Warranty periods that
a

pply). You can determine your unit’s warranty status by obtaining the complete model number, the complete serial number, and the date of original installation
a

nd accessing the “Warranty Verification” functionality on the Raypak website (www.Raypak.com) or contacting Raypak Warranty personnel (telephone number
[phone]). To establish Lifetime Residential Limited Warranty coverage you must be able to provide proof that you purchased the indirect unit that is the
subject of your warranty claim. If your indirect water heater is “in-warranty”, refer to the installation and operation manual provided with it or contact the Raypak
Technical Service Department (telephone number [phone]) to obtain the technical assistance you need to repair or replace your defective indirect unit.
You may also use the plumber of your choice or select a plumber, or mechanical contractor, from your local Yellow pages to assist you – at your expense. Be
prepared to provide the plumber, mechanical contractor, or Raypak Technical Service person you call with the complete model number, the complete serial
n

umber, and the date of original installation or the date of the owner’s purchase of the defective indirect water heater in addition to an explanation of your indirect
water heater problem. If an exact replacement unit is not available, Raypak will provide you with the current model of your indirect water heater. If government
regulations or industry certification or similar standards require the replacement indirect water heater, or replacement component part, to have features not found
in the malfunctioning indirect water heater, you will be charged for the difference in price represented by those required features. If you pay the price difference
for those required features and/or to upgrade the size and/or other features available on a replacement new indirect water heater, you will also receive a
complete new Limited Warranty (with the full applicable Warranty periods the original unit entitled you to) for the replacement indirect water heater. Raypak
reserves the right to inspect, or require the return of, each indirect water heater or defective component part replaced under the terms and conditions of this
L

and all the component parts intact) in exchange for the replacement indirect water heater. Warranty compensation is subject to validation of “in-warranty”
coverage by Raypak.
