2.1 HEATING WITH HOT WATER

Your HYDRA III electric boiler was carefully assembled
and checked in our plant, so that it will deliver warmth
and comfort to your home for many years to come.

This manual is intended to provide the necessary
information for the installation of the unit, how it functions
and explains security measures which are particular to
this type of equipment.

It is essential that the persons installing, operating
or adjusting the boiler carefully read this manual, in
order to completely understand and be familiar with the
procedures to be followed.

• A pressure relief valve, adjusted to 30 psi;

• A drain valve;

• An exterior probe for modulation;

• Two 1" X ¾" (15-20 kW) or 1¼" X ¾" (24-29 kW)
reducers for drain valve and pressure relief valve.

2.3 POSITIONING AND
CLEARANCES

The unit must be installed in an area that is dry, non­corrosive, without excessive dust, well ventilated and
where the ambient temperature does not exceed 27°C
(80°F).

The boiler can be installed using the included mounting
brackets. First, unfold the four tabs on the back panel of
the boiler. Position the top bracket and secure it to a wall.
Place the boiler on the top bracket and then secure the
bottom. Finally, use self-tapping screw to secure the tabs
to the bracket. Ensure that the unit is well fixed on the
wall utilizing the 2 mounting brackets.

The boiler can be installed in 6 possible configurations as

2.4 DISTRIBUTION SYSTEM

The proper functioning of your heating system is directly
related to the quality of the plumbing installation.
Therefore, the entire installation must be performed by
qualified technicians.

See Figure 4 for the various boiler components.

The heating system should be set-up to operate at
a pressure around 12 psi. The maximum operating
pressure is 28 psi, but such a high pressure is abnormal
and requires inspection from a service technician. The
operating temperature may range from 5°C to 88°C (41°F
to 190°F).

All installations must include the following items:

• 1 pressure regulator, adjusted to 12 psi, must be
installed between the boiler and the main water
supply in the building;

• 1 expansion tank, pre-pressurized to 12 psi and of
appropriate size;

• 1 or more circulating pumps of appropriate
capacity.

• 1 or more air purge valves;

2.4.1 Circulating Pump

The circulating pump must be selected according to
the heating distribution system and the heating capacity
of the boiler. Table 2 shows necessary water flows
according to various temperature rises. For example, a
system using baseboard heaters will usually require a
temperature rise of 20°F, wheras a radiant floor system
will use a rise around 10°F.

2.4.2 Freeze protection (when required)

WARNING

Only propylene glycol may be used in this
hydronic heating system to prevent freezing.
It is recommended to add a maximum of 50%
of propylene glycol mixture to ensure proper
operation.
Do not use automotive anti-freeze, ethylene glycol
or any undiluted anti-freeze.
If the above recommendations are not followed,
severe personal injury, death or substantial
property damage can result.

WARNING

BURN HA ZA RD
To avoid water damage and/or scalding due to
relief valve operation, a discharge line must be
connected to the valve outlet and run to a drainage
area. The discharge line shall be installed in such
a way that it will allow for the complete drainage of
the valve and the discharge line.

6

2.5 BOILER INSTALLATION

At the time of installation, the following steps should be
followed. Refer to Figure 5, Figure 6, Figure 7 and
Figure 8.

1. Choose an appropriate location. Mount the boiler
securely on the wall with the help of the mounting
plate. Ensure that it is level and that the minimum
clearances are observed;

2. Install the drain valve and the safety valve
according to the mounting configuration as shown
in Figure 1;

3. Install the water supply and return piping with the
1” NPT (15 to 20 kW) or 1¼" NPT (24 to 29 kW)
fitting;

4. The heating supply line must include:

(a) 1 circulator along with 2 maintenance valves;

(b) 1 automatic pressure reducing valve adjusted

to 12 psi, with a shut-off valve on the return
water line;

(c) 1 expansion tank;

(d) 1 automatic vent.

5. In order to ensure satisfactory water flow, the
friction in the piping system must not exceed the
capacity of the circulator;

Make sure to turn off all electrical circuits when
working in the appliance.

WARNING

FI RE HA ZA RD
The conductor sizing must conform to the last
edition of the local or national codes.

Power supply to the unit can be made using copper
or aluminum wires. The wire size must be decided in
accordance to unit power consumption, the over current
protection type and capacity, the wire type and length,
and the environment where the unit is installed. If an
aluminum wire is used, other precautions (such as the
use of a DE-OX inhibitor) must be taken to insure the
conformity of the installation. In all cases, all the factors
affecting the wire gauge must be considered and the
installation codes followed.

The exterior of the unit must have an uninterrupted
ground to minimize the risk of bodily harm. A ground
terminal is supplied with the control box for that purpose.

It is highly recommended to have a surge protector
installed on the boiler.

In the event that wires inside the unit require
replacement, these must be as same type as originals
(copper wiring only).

6. After having completed all piping connections, run
water through the system and purge the air. An
automatic vent should be in operation.

Note: Remove the top cover and check to see if the
elements are watertight.

2.6 ELECTRIC POWER SUPPLY

All electrical wiring must conform to the standards and
regulations in force and to the Canadian Electrical Code
CSA C22.1.

Electric power to the boiler must come from a 120/240V
60 Hz or 208V 60 Hz, single phase, grounded circuit,
protected by an appropriately sized breaker, based
on the total rating of the boiler. Refer to the boiler
nameplate and the technical specifications in this manual
to select the proper breaker and wire size. Normally, 3
conductors are required. If the circulating pump has an
external power source, and if no other accessory requires
the 120V output from the boiler, only 2 conductors can
be used. Use cable rated at 60°C or higher.

When using 208V, change the connector’s position at the
primary of the transformer.

2.6.1 Connecting the Circulation Pump

Connect the circulating pump on 120V connection points
identified N for neutral and P for controlled 120V output
in the control panel. The electronic control is designed to
operate the circulator on thermostat demand, with a heat
purge delay at the end of heating cycle or continuous
flow. Refer to the electronic control section to learn how
to configure this function.

2.6.2 Single and Multiple Zone
Connections

Single Heating Zone

Connect the low voltage thermostat to R(T)-W(T)
terminals located inside the control panel. See Figure 5.

Multiple Heating Zone

Connect the contacts of the motorized valves or pump
controls to R(T)-W(T) terminals inside the control panel.
See Figure 6 and Figure 7.

2.6.3 Outdoor Sensor Connection

electronic control.

Mount the sensor on an outside wall, protected from
direct sunlight, so that it will accurately measure the
outside temperature. Install 2 #20 wires between the
outdoor sensor and the terminals identified as

EXT2

inside the control panel of the boiler. This sensor
will allow the boiler to modulate its set point according to
the outdoor temperature, as per figure 3.

3 OPERATION

3.1 ADJUSTMENTS AND

START-UP

CAUTION

The boiler must be filled with water and all air purged
from the system, before turning on the power. If
the power is turned on before the boiler is filled with
water, the elements will become seriously damaged.
Warranty will be void.

3.3.2 Manual Reset High Limit Control

Turn the power to the unit off before resetting the high
limit. The manual reset high limit is set at 100°C (212°F).
To reset this protection, the boiler needs to cool down.
Then the black button shall be pressed using a pen or
screwdriver. Refer to figure 4 to locate the high limit
thermodisc.

1. Turn the power on.

2. Adjust the set point of the boiler on the electronic
control. See the electronic control section for
adjustments.

3. Set the thermostat at 30°C (85°F). The circulator
should start as well as the electrical elements in
sequence with a 15 seconds delay, if CMD displays
100% (see section 3.4.1).

4. The circulator stays on for as long as there is a
call for heat except if differently configured on the
electronic control, as explained in section 3.4.2.

3.2 OPERATING PRINCIPLE

The control activates the electrical elements. There is
a delay before turning on (2 minutes max.) or off (30
seconds max.) each individual element. When the set
point is reached, the number of activated elements will
be adjusted in order to maintain the water temperature,
while minimizing the on/off cycling. This allows for a
better longevity of all components and energy savings.

4 MAINTENANCE

It is recommended that the boiler be purged annually, in
order to eliminate sediment and sludge that may have
accumulated at the bottom of the boiler and covered the
heating elements.

Procedure:

The property owner has the following responsibilities:

1. To maintain the area around the boiler clean at
all times and free from combustible and highly
flammable material;

2. To ensure that the ambient air at the boiler is not
excessively dusty or humid;

3. To have all water leaks repaired in the system as
they arise.

4. To ensure that the ambient temperature in the area
where the unit is installed does not exceed 27°C
(80°F).

CAUTION

The boiler guarantee may be invalidated if: water
leaks in the system are not repaired; the boiler is used
as a source of domestic hot water; or a significant
amount of new water or air is introduced into the
system.

1. Let the boiler cool down;

2. Close the maintenance valves, which are installed

at the water inlet and outlet of the boiler. N.B.: It

is not recommended to drain the water from the
heating pipe system;

3. Hook-up a garden hose to the drain valve and place
it close to a floor drain;

4. Open the purge valve until the water comes out
clean and clear;

5. Close the valve.

It is recommended to perform a visual inspection of the
boiler electrical compartment annually, during the heating
season. The items to check are the water tightness
of the elements, signs of overheating of the electrical
components and the wiring. Corrective measures must
be undertaken as required, as soon as possible.

Defective components should always be replaced with
the Original Equipment Manufacturer’s parts.
