Starting at the back of the brick core cavity,
load bricks one row at a time using left side,
right side, center pattern. Place bricks with
grooved side facing up, notch facing forward,
and ridges on left and right.

BRICK LOADING

 Remove loose

debris from brick.

 Brick rows MUST line

up front to back
and side to side.

 Use half bricks in proper rows and in

correct positions. Back half of brick
MUST be installed in back rows. Front
half (notched brick piece) MUST be

BRICK CORE TEMPERATURE SENSOR(S) INSTALLATION

WARNINGWARNING

WARNING

WARNINGWARNING

Risk of improper operation. Proper installation of the brick core temperature sensor(s) is critical to the
operation of the Comfort Plus Hydronic system. Read and follow installation instructions carefully.

1. Remove screw(s) by temperature sensor hole(s) in galvanized front panel.

2. Insert temperature sensor(s) through hole(s). Sensor(s) must pass through blanket insulation and into brick core.

3. Install screw(s) into galvanized front panel to hold sensor(s) and provide electrical ground connection.

4. Inspect sensor wiring for possible short circuiting hazards.

5. Install painted front panel.

NOTE: Models 5130 and 5140 have an upper and a lower temperature sensor. Each sensor is marked for proper installation.

WARNINGWARNING

HAZARDOUS VOLTAGE: Risk of electric shock, injury or
death. Do not energize the Comfort Plus Hydronic system
until installation is complete.

1. Route all line voltage wires through knockout(s) and into electrical
panel.

2. Make proper field wiring connections.

 To ensure proper operation and safety, all line voltage cir-

cuits must be segregated from low voltage wiring.

 To reduce electromagnetic fields associated with electrical

circuits and to avoid induced voltage on sensors and elec­tronic devices, the circuit phases MUST be alternated as
shown below.

 DO NOT install any wiring in the line voltage compartment of

the Comfort Plus Hydronic system unless it is rated for line
voltage.

AIR CONDITIONER/HEAT
PUMP INTERFACE

The Air Handler (Order #1302100) is an optional
device used to interface the Comfort Plus
Hydronic with a ducted heating or cooling
system such as a heat pump or air conditioner.
The Air Handler includes a plenum assembly,
supply air blower, water coil, air filter, wiring
harness, and hardware kit. When the Comfort
Plus Hydronic system receives a heat call from
the room thermostat, it energizes the supply
blower and the Air Handler's zone pump.

The Air Handler can be interfaced with a
standard heat pump system and will provide
comfort modulation. The system will monitor
the outlet air temperature and modulate in heat
from the Comfort Plus Hydronic as needed to
maintain the desired output air temperature.

The maximum coil size the Air Handler can
accommodate through the front access is 20"
(W) x 22" (H) x 21 3/16" (D). The inner dimen­sions of the A-coil area are 21 3/16" (W) x 24 1/
4" (H) x 21 3/16" (D). If installing a coil larger
than the access dimensions, the coil must be
placed into the Air Handler during assembly.

WARNINGWARNING

WARNING

WARNINGWARNING

Risk of fire. Any one ducting system
MUST NOT contain more than one air
handling (blower) system. If the applica­tion requires multiple Comfor t Plus
heating systems or it is necessary to
have multiple air handlers share the
same ductwork, you MUST contact
Steffes Corporation. There are special
installation requirements that MUST be
performed in an application such as this.

JUNCTION BOX INSTALLATION

1. Attach the factory supplied junction
box to the left side of the Comfort
Plus Hydronic system.

2. Make connections to the primary loop
pump and air handler pump inside
this junction box. The red and white
wires connect to the primary loop
pump and the black and white wires
connect to the air handler pump. The
maximum connected amperage on
either of these circuits is 1.2 amps.

3 . Attach the junction box cover using

the screws provided.

PLUMBING

The Comfort Plus Hydronic heating system MUST be plumbed with a primary loop and secondary (zone) loops. The primary loop
needs to consist of a minimum of 10' of 1" pipe and requires its own pump* (circulator). The secondary (zone) loops require
additional pump(s) to operate effectively.

WARNINGWARNING

WARNING

WARNINGWARNING

FREEZE PROTECTION: Risk of property damage. Hydronic heating system freeze-ups WILL cause extensive
damage to the entire heating system and/or property. It is the responsibility of the installer to provide protec­tion against freezing.

PIPING SUPPORT: Risk of equipment damage or personal injur y. DO NOT use the exchanger as support for
piping. Support of primary loop and associated plumbing must be installed to ensure proper operation of the
system and to keep pressure off the inlet and outlet piping.

PRESSURE RELIEF VALVE INSTALLATION

WARNINGWARNING

WARNING

WARNINGWARNING

Risk of explosion, injury, or death. The factory
supplied pressure relief valve MUST be
connected to the system with the supplied

fittings.

w DO NOT modify this assembly.

1. Remove the heat exchanger access panel and locate the
pressure relief valve assembly.

2. Using the supplied union fittings, connect the pressure relief
valve to the outlet water port on the left side of the Comfort
Plus Hydronic system.

3. Use schedule 40 pipe to install a discharge line for the pressure
relief valve.

4. Install heat exchanger access panel.

w DO NOT cap, plug, or otherwise

WARNINGWARNING

WARNING

obstruct the outlet of the pressure
relief valve.

w DO mount the pressure relief valve in

a vertical, upright position.

w This pressure relief valve is sized to

service the needs of the Comfort Plus
Hydronic system. If multiple heating
systems are being used, pressure
relief valving for the other system
MUST be provided separately.

Risk of injury or property damage. During operation, the
pressure relief valve may discharge large amounts of
steam and/or hot water. To reduce the potential for bodily
injury or property damage, install a discharge line.

w DO use schedule 40 pipe for the discharge line.

w DO NOT use schedule 80, extra strong pipe

or connections on the discharge line.

w DO NOT cap, plug, or otherwise obstruct the dis-

charge pipe outlet.

w DO follow all local, state, and national codes and

regulations.

SOFTWARE CONFIGURATION

The Steffes Comfort Plus Hydronic system has a Configuration
Menu, which allows it to be customized to the power company
and consumers needs. This menu can be accessed on start­up and allows configuration settings to be easily adjusted.

If access to Configuration Menu times out, the 15
amp circuit breaker must be powered off and back
on to re-enter the menu.

Accessing the Configuration Menu

Step 1 Energize the system. Access to the Configuration

Menu is allowed for the first two (2) minutes of
operation. If the system has been energized for
over two (2) minutes, it must be powered off and
back on again.

Step 2 Press and release the M button until the faceplate

displays CONF.

Step 3 Press the up arrow once and the faceplate will

display C000. The display will flash between
C000 and the corresponding configuration value.

In most applications only a few, if any, configuration changes will be necessary. Following is a description of the configuration
settings and their functions:

Step 4 If necessary, edit the configuration by pressing and

holding the M button while using the up or the down
arrow button to change the value.

Step 5 Once the value is correct, release the buttons and

press the up arrow button to go to the next
configuration (C001, C002, etc.).

Step 6 Repeat steps 4 through 5 until all configuration

settings have been adjusted to the desired values.

Step 7 Once configured, use the down arrow to leave the

Configuration Menu.
