Installation steps
Prior to lifting the Family PRO Boiler onto the wall, use the enclosed
template to level and locate the wall bracket.
- fasten the boiler support plate to the wall and use a spirit level
to make sure it is perfectly horizontal
- mark the placement of the 2 holes for securing the boiler support
plate make sure that all measurements are exact, then drill the
wall using drill tips with the diameters indicated on the wall
template
- fix the plate, using the wall template, to the wall
- hang the boiler
- fix the pressure relief valve (PRV) ad described on the wall
template
- install the condensate check valve
- install the gas valve main supply
- install the exhaust flue and intake air piping
- carry out the electrical connection according to local code rules
7.3
ASME pressure relief valve
The Family PRO has a pressure relief valve supplied with the
boiler.
Connect the valve hydraulically on the heating supply connection
and in vertical position (see reference picture).
This device is designed for emergency safety relief and shall not
be used as an operating control.

WARNING:
To avoid water damage or scalding due to relief
valve operation:

condensate

the discharge line must be connected to relief valve outlet and
run to a safe place of disposal. Terminate the discharge line in a
manner that will prevent possibility of severe burns or property
damage.
− the discharge line must be as short as possible and be the
same size as the valve discharge connection throughout its
entire length.
− the discharge line must pitch downward from the valve and
terminate at least 6’’ (152 mm) above the floor drain where any
discharge will be clearly visible.
− The discharge line shall terminate through plain (unthreaded) pipe.
The discharge line material must conform to local plumbing code or
A.S.M.E. requirements
− No shutoff valve shall be installed between the relief valve and the
boiler, or in the discharge line.
− Do not pipe the discharge to any place where freezing could occur.
− Do not plug or place any obstruction in the discharge line.
− Test the operation of the valve after filling and pressurizing system
by lifting the lever. Make sure the valve discharges freely. If the valve
fails to operate correctly, replace it with a new relief valve.
− For boilers installed with only a pressure relief valve, the indirect
tank (if used) must have a temperature and pressure relief valve
installed. This relief valve shall comply with the standard for
Relief Valves for Hot Water Supply Systems, ANSI Z21.22/CSA4.4.
− Failure to comply with the above guidelines could result in the
failure of the relief valve to operate, resulting in the possibility of
severe personal injury, death or substantial property damage.
− For safe operation of the appliance, the relief valve must not be
removed or plugged.
Maintenance of the relief valve
9
CAUTION
: The valve lever must be operated at least once a
year by qualified personnel during annual maintenance to
insure that water-ways are clear.
Certain natural occurring mineral deposits may adhere to the
valve, rendering it inoperative.
When manually operating the lever, water will discharge and
precautions must be taken to avoid contact with hot water to
avoid water damage.
Before operating the lever, check to see that a discharge line is
connected to this valve directing the flow of hot water from the
valve to drain otherwise personal injury may result. If no water
flows, the valve is inoperative.
Call a qualified plumber immediately.
Pressure relief valve should be inspected at least once every three
years by a licensed plumbing contractor or authorized inspection
agency, to insure that the product has not been affected by
corrosive water conditions and to insure that the valve and
discharge line have not been altered or tampered with illegally.
Certain naturally occurring conditions may corrode the valve or its
components over time, rendering the valve inoperative.
Such conditions are not detectable unless the valve and its
components are physically removed and inspected.
Do not attempt to conduct this inspection on your own.
Contact your plumbing contractor for a reinspection to assure
continuing safety.

WARNING:
Failure to reinspect this valve as directed could
result in unsafe pressure buildup which can result in serious
injury or death and/or severe property damage.
7.4
Installing the condensate check valve
It is mandatory, before starting the boiler, even just temporarily, to
install the condensate check valve supplied as standard.
For the installation proceed as follows:
- remove the plug (T) from the condensate trap
- carefully secure the condensate check valve, using the proper
gaskets, screwing it on tight and checking its seal
- connect a pipe for draining the condensate to a suitable
collection and evacuation system in the white water outlet and
in compliance with current legislation.
9
WARNING
: the manufacturer is NOT responsible for any
damage caused by the installation of the boiler without
the condensate check valve being correctly positioned. An
improperly installed or damaged condensate check valve
may result in substantial property damage, severe personal
injury or death.
Install the flexible condensate drain pipe (Ø 7/8” - 21 mm flexible
rubber female connection) with a suitable gradient to avoid
condensate stagnation.
Discharge condensate from the boiler into the drainage system,
either directly or (if required) via a neutralizer kit (not supplied).
The condensate drain of the boiler is equipped with a built-
in condensate trap in order to keep flue gases from being
discharged via the condensate drain.
The condensate formed both in the condensing boiler and in
the flue gas pipe must be discharged into the public sewage
system in accordance with all applicable local regulations.
The condensate produced by a gas-fired heating system has a
pH value between 3 and 4. Some local codes may require the use
of a separate neutralizer kit to treat the aggressive and corrosive
condensate. With a neutralizer kit installed, all condensate from
the boiler and the flue gas pipe enters into the neutralizer kit
where it is treated and released into the public sewage system
with a safe pH value of above 6.5.
The use of neutralization granulate (performing the neutralizing
process) is dependent on the operation of the heating system.
To determine the required refill amount, check granulate level
several times during the first year of operation. In some cases one
granulate fill may last an entire year.
The condensate discharge outlet to the drainage system
connection must be clearly visible. It must be installed with a
suitable gradient and provided with a stench trap.
If the condensate outlet of the boiler is lower than the drain, a
condensate pump must be used.
Only corrosion-resistant materials may be used for condensate
drainage purposes (e.g. braided hose). Do not use galvanized
materials or materials containing copper for piping, couplings etc.
Please note that other requirements may apply depending on
local regulations and/or project-specific details.
