Indirect Fired

Water Heater

Suggested Specifications

SMART Series

General Requirements

A. Furnish and install _____ (qty) Indirect Fired Water

Heater designed for the production of domestic hot
water using boiler water as a heating source.

B. Installation of the Indirect Fired Water(s) shall be

according to manufacturer’s installation instructions
and all work shall be completed in a neat and work­manship like manner.

C. The Indirect Fired Water Heater shall be a Triangle

Tube SMART _______ having a minimum continu­ous (recovery) of _____ GPH at a 90°F domestic
temperature rise at boiler output listed in the perfor­mance table on page 3 and a minimum actual stor­age capacity of not less than _______ gallons per
water heater.

D. The water heater shall have a minimum of _______

square feet of heat transfer surface area.

E. The water heater shall be designed for a maximum

boiler side pressure drop through the outer tank of
3ft of pressure loss or less at volume flow rate of 28
gpm.

1. Consist of two (2) concentric tanks. The inner
tank shall contain the domestic water and the
outer tank shall contain the heating system
water. This “Tank in Tank” design concept shall
allow the inner tank to be self-descaling.

2. The inner tank shall be 304L corrugated stain­less steel material that is passivated to provide
additional resistance to corrosion.

3. The inner tank shall have a maximum working
pressure of 150 psi and shall be able to withstand
a hydrostatic test pressure of 300 psi.

4. The outer tank shall be of carbon steel material
and have a maximum working pressure of 45 psi.

5. The water heater shall provide a cold water inlet
connection, hot water outlet connection and an
AUX connection that is to be utilized for the
Temperature / Pressure relief valve or a recircu­lation return connection.

6. The outer tank shall be covered with a minimum 2
inches of CFC/HCFC-free rigid polyurethane foam
insulation with an equivalent “R” value of 16.

F. The water heater shall have a standby loss less than

1°F per hour.

G. The water heater shall have a maximum allowable

system heating water temperature of 210°F.

H. The water heater shall comply to the construction

standards of UL 174 and be certified by ITS/ETL or
other third party agency.

Product Specifications

A. Water Heater Construction

7. The water heater shall be covered by a single
piece polypropylene exterior jacket that resists
dents, cuts and abrasions.

B. Temperature Control

1. A drywell shall be inserted into and extend the
full length of the inner tank.

2. Within the drywell shall be a remote sensing
bulb attached to a low voltage thermostat that
senses the water temperature in the tank.

Suggested Specifications - SMART Series

3. The thermostat shall open a circuit contact when
the temperature rises above the set point and
shall close when the temperature falls to a tem­perature no more than 9°F below the set point.

4. The thermostat shall be adjustable from 90º F to
a maximum temperature setting of 164°F for
residential and 194°F for commercial.

5. The thermostat shall be mounted on a remov­able cover plate and wired to a removable snap­set connector to allow easy installation and ser­vicing. All field wiring to the thermostat / snap­set connector shall be 24V.

C. Field Installation

1. The water heater shall have a field installed
Temperature / Pressure relief valve with a minimum
element length of 8 inches (extended element).

2. The T&P relief valve shall bear the ASME rat­ing, have a relief pressure of 150 psi and a relief
temperature of 210°F.

B. The Indirect Fired Water Heater(s) shall comply

with the National Standard Plumbing Code provid­ed that:

1. The boiler (system heating) water (including
additives) is practically non-toxic, having toxic­ity rating or Class of 1 as listed in Clinical
Toxicology of Commercial Products and

2. Boiler water pressure is limited to a maximum
30 psig by an approved relief valve.

C. The Indirect Fired Water Heater(s) shall comply

with the Uniform Plumbing Code Paragraph L3.2
and L3.3 provided that:

1. The heat transfer medium is potable water or
contains only substances which are recognized
as safe by the US Food and Drug
Administration.

2. The pressure of the heat transfer medium is
maintained less than the normal minimum oper­ating pressure of the potable water system.

D. Manuals

1. The water heater(s) shall be provided with com­plete instruction manuals, including:

a) Operational and Maintenance Manual

Warranty

A. The water heater shall carry a limited lifetime war-

ranty when installed in a residential application.

B. The water heater shall carry a six (6) year non-pro-

rated warranty when installed in a commercial
application.

Code Requirement

A. The Indirect Fired Water Heater(s) shall be recog-

nized as an ASME Equal by the Commonwealth of
Massachusetts Plumbing Board.

3. The equipment is permanently labeled to indicate
that only additives recognized as safe by the FDA
shall be used in the heat transfer medium.

Other heat exchangers designs may be permitted where
approved by the Administrative Authority.

D. The installer shall be responsible to ensure that the

installation of the Indirect Fired Water Heater is in
compliance with all applicable local, state and
national codes.
