1 USER'S MANUAL

1.1 Introduction

The new PEGASO ECO is a high-performance, low-

emission heater for domestic hot water production,

compact, WATER-COOLED, battery-powered burner

with electronic ignition, designed for indoor and outdoor

installation (from -5 ° C to +60 ° C).

1.3 Turning the heater on and off

When the unit is working, the

temperature near the peephole

may be high. Avoid contact as

there may be risk of burns.

Preliminary checks and operations

1 Make sure the hot water taps are closed.

2 Open the gas supply cock to the heater, located at the

gas connection to the unit.

3 Check that the 1.5 V batteries are properly installed

with the correct polarity (+/-). To replace the batteries,

see (3.4 Replacing the batteries).

4 Also verify that the batteries are sufciently charged

for heater operation.

1.3.1 Turning the unit on

Turn the knob to the required water heating level.

The unit will begin operating every time hot water is

drawn.

g. 2 - Turning the unit on

1.3.2 Turning the unit off

The burner goes off automatically when hot water is no

longer demanded.

To use the unit again, no action is required.

To completely shut off the unit, place the knob in the ()

position .

g. 3 - Turning the unit off

If the water heater will not be used for an extended pe-

riod of time, close the gas cock supplying the unit.

If the unit will be inactive for an

extended period of time during

the winter, all water should be

removed to avoid ice damage.

PEGASO ECO

cod. 3542C010 - Rev. 00 - 09/2022

1.4 Settings

1.4.1 Setting the burner power manually

Use the knob (3 g. 1) to select the heater power. You

may choose between the minimum, maximum, and in-

termediate positions, depending on the required heating

power.

If the knob is turned counterclockwise, the unit will ope-

rate at maximum power. If the temperature is too high,

for example in the summer, or if you need a reduced

ow of not very hot water, turn the knob clockwise. This

reduces the power, and therefore the gas consumption.

In the ●position, the unit is turned off.

1.4.2 Setting the temperature

Turn the water temperature selector clockwise to incre-

ase the temperature, or counterclockwise to decrease it.

g. 4 - Setting the temperature

1.5 Faults

Once the adjustments described above have been made,

the heater is ready to operate automatically. When a hot

water tap is opened, an intermittent discharge is genera-

ted on the ignition electrode to light the burner.

All electronic models have an ionization electrode built

into the burner to monitor ame presence. If a malfun-

ction or lack of gas causes the heater to turn off, close

the hot water tap.

It is then necessary to eliminate the fault or obstacle pre-

venting the gas from reaching the heater, e.g., inadver-

tent closing of the gas cock, empty gas cylinder, etc.

To reactivate the heater, close and open the hot water

tap.

If no hot water is produced after eliminating the cause

and opening the hot water tap, repeat the process.

If the problem persists, call the technical support center.

2 INSTALLATION MANUAL

2.1 General information

The heater may only be instal-

led by an authorized technician,

in accordance with all instruc-

tions contained in this manual,

standard UNE 26, and local in-

stallation and exhaust regula-

tions.

2.2 Location

Make sure the water heater chosen is the most suitable:

•To adequately meet the system’s hot water require-

ments.

•For the gas to be used (see water heater dataplate).

•For the water supply pressure, necessary for operation

(see table of characteristics).

Make sure the room where the unit is installed meets

all the requirements of the Current Regulations. In

particular, this unit is an “open chamber” type and

must only be installed and operate in permanently

ventilated places. An insufcient supply of combu-

stion air will compromise normal operation and the

evacuation of fumes. Also, the fumes forming under

these conditions are extremely harmful to health if

dispersed in the domestic environment. OTHERWI-

SE THERE MAY BE RISK OF SUFFOCATION AND IN-

TOXICATION OR EXPLOSIONS AND FIRE.. Therefore

the place of installation must be free of dust, am-

mable materials or objects or corrosive gases.

Position the water heater as close as possible to the hot

water taps, near the sink, but NEVER above a cooktop.

It must also be situated as close as possible to the ue

or the start of the ue gas exhaust pipe.

If the unit is installed inside a cabinet or

joined laterally to other elements, space

must be allowed for removing the casing and

performing normal maintenance activities.

2.5 Gas connection

Before making the connection,

check that the unit has been pre-

pared to operate with the right

type of fuel, and carefully clean

the gas pipes to remove any re-

sidue that might hinder correct

operation. Make this connection

in accordance with the dimen-

sions and connections in sec-

tion 4.1.

1 Connect the corresponding gas inlet (see section 4.2)

in accordance with current regulations in the country

where the heater is being installed.

2 Connect using a rigid metal pipe (connection to

a gas supply network) or a exible, continuous

stainless steel pipe (LPG installation), adding a

shut-off valve between the installation and the unit

(AS CLOSE TO THE UNIT AS POSSIBLE).

3 Once the connection to the gas network is complete,

check that all gas connections are tight. For this

purpose, a tightness test must be performed. To avoid

damage to the unit due to excess pressure, leave the

gas inlet valve closed.

4 Check that the supplied pressure and gas delivery

values are those indicated for the unit's consumption.

See the technical data table (section 4.5).

In installations with an appro-

ved exible pipe for LPG, pay

special attention to the fol-

lowing.

• The pipe must comply with applicable regulations.

• Avoid areas with heat emissions.

• Prevent the pipe from bending or being pinched shut.

•The connections on both sides (gas valve and other

components) must comply with the regulations of the

country where the heater is installed.

2.6 Air and ue gas ducts

The diameter of the pipe connecting to the ue must not

be smaller than that of the pipe connecting to the draft

hood. After the draft hood, there must be a vertical seg-

ment at least half a meter long. The dimensions and in-

stallation of the ues and the tube connecting to them

must comply with current standards.

2.6.1 FUME EXHAUST SAFETY DEVICE (fume thermostat)

•The water heater’s safety device ensures the correct

exhaust of ue gases; THEREFORE DO NOT DEAC-

TIVATE IT OR CARRY OUT ANY OPERATION ON IT.

•If the safety device cuts in when the water heater is

started, check the ue gas outlet, checking the exhaust

with a cold mirror or with any suitable and approved

measuring device.

•In case of a fault, only use original replacements,

otherwise the safety device may not work properly.

•Fume thermostat replacement must be carried out by

qualied technicians, proceeding as follows:

- - Remove the faulty fume thermostat by undoing the

2 xing screws.

- - Install a new original thermostat.

- - Fix the fume thermostat in its place without over-

tightening the screws.

- - Check its correct operation.

Remember to make an air inlet

opening in the room where the

water heater is installed (as re-

quired by the current regula-

tions).

If the above instructions are

not observed there may be risk

of suffocation or poisoning

due to gas or fumes escaping.
