-Pressure relief valve-
The water heater has a high-temperature shutoff switch built in as a standard safety feature (called a 
Hi-Limit switch) therefore a “pressure only” relief valve is required.
•	This unit does not come with an approved pressure relief valve.
•	An approved pressure relief valve must be installed on the hot water outlet.
•	The pressure relief valve must conform to ANSI Z21.22 or CAN 1-4.4 and installation must follow local 
codes.
•	The discharge capacity must be at least...

PUMP CONTROL CONNECTIONS
Available on the 510 (T-D2) model only
The 510 (T-D2) model water heater can be used to control a recirculation pump.  Proper pump control 
helps to preserve the life of the system and saves energy as well.
The water heater pump control port is a “normally-open dry contact”, and therefore needs additional 
components to properly control a recirculation pump, such as a relay.  To control a recirculation pump, 
connect the pump to a relay...

EASY-LINK SYSTEM
(Available on the 510 (T-D2) model only)
The 510 (T-D2) model water heaters can be connected with other allowable heaters (see the 
table below) with communication cables to work as a multiple-unit manifold system.
•	The Easy-Link System allows up to 4 units to manifold together.
•	A communication cable (gray color) comes with each 510 (T-D2) model.
You can manifold from 2 to 4 units without the need for a multi-unit controller.  A 4-unit system 
has full automatic modulation...

5. Between the “PARENT” and the “CHILD-1” units:
 Connect the “PARENT” connector of the “PARENT” unit to the “1” connector of the “CHILD-1” unit 
using the supplied linking cable.
6. Between the “CHILD-1” and the “CHILD-2” units:
 Connect the “2” connector of the “CHILD-1” unit to the “1” connector of the “CHILD-2” unit.
7. Between the “CHILD-2” and the “CHILD-3” units:
 Connect the “2” connector of the “CHILD-2” unit to the “1” connector of the “CHILD-3” unit.

•	Unless you change DIPswitch No. 1 of the “PARENT” unit to the “ON” position, the system will 
not work as an Easy-Link System.  The units will operate as individual units.

CASE 3: Wrong connections between the "CHILD-1" unit and the "CHILD-2" unit
CASE 4: Remote controller connected to incorrect unit
Connecting two “PARENT” connectors together from two separate units may 
damage the computer board.  The communication cable has a female end and 
a male end so it’s impossible to have a PARENT-to-PARENT connection with the 
communication cable.  Do not splice or modify connectors.WARNING

APPLICATIONS
-Space-Heating Applications-
-Recirculation-
*The recirculation pump is to be controlled by:
-Dual-set aquastat (recommended w/timer) or -"Pump Control Connections" 510 (T-D2) model only. (Refer to p.23.)
*The recirculation pump is to provide no less than 2 GPM and no more than 4 GPM through
  each activated unit in the system.
•	This water heater is suitable for combination water (potable) heating and 
space heating and not suitable for space heating applications only.
•	In...

•	Priority Control Devices such as a flow switch, an Aquastat or other 
electronic controller can be used to prioritize the domestic water system over 
the heating system.
•	Follow all local codes, or in the absence of local codes, follow the most recent 
edition	of	the	 National	 Standard	 Code,	ANSI	Z21.10.3.
•	This illustration is a concept design only.  The reference to the 1/8th hole 
in check is only for the State of Massachusetts.  There are a wide variety
