GAS CONNECTION

WARNING!
Installation, first ignition and mainte-
nance work must be performed by qual-
ified personnel only, in accordance with
the instructions provided.
- Make sure that the main gas supply
matches the gas type on the unit's
data plate
- Open all doors and windows
- Make sure there are no sparks or na-
ked flames in the room
- Water heaters are normally adjusted
for operation using methane gas G20
(PCI) 8100 kcal/m3 approximately. No
adjustment is needed if this gas is in
use.
Adjustment for other types of gas must
be done only by qualifi ed personnel.
- Use a 1/2" size pipe to connect the gas
supply to the valve.
- We suggest you fi t a stop valve in the
gas supply line, upstream of the gas
unit.
- Make the connection to the gas sup-
ply using rigid pipes (steel, copper
etc) and not thermoplastic nor rubber
pipes.
- After taking off the cover and making
the connection, check for leaks in the
gas system using soapy water.
Do not use a fl ame for this test.

The water heater has a magnesium an-
ode fitted in the tank. The life of the an-
ode
is proportional to the average tempera-
ture, the chemical composition and the
amount of water supplied.
We suggest you check the state of the
anode every 18-24 months, noting that
the surface must be relatively smooth.
If the diameter is less than 10-12mm, we
suggest you replace the anode with a
new original anode.
The anode is fi tted in the lower part of
the water heater, below the protection
cover.
IMPORTANT!
TO ADAPT THE WATER HEATER
WITH A GAS DIFFERENT FROM
CALIBRATION ONE YOU MUST
PROCEED TO CHANGE THE NOZZLES.
IT IS ADVISABLE TO EXECUTE THE
NOZZLES CHANGE BEFORE PRODUCT
INSTALLATION TO AVOID
DISASSEMBLING THE GAS GROUP.
