1INTRODUCTION
CYBER SECURITY NOTICE
SV2 Series products contain electronics and software. Care
should be taken by the installer / facility management
to guard against unauthorized access to the valve and to
the programming interface for parameter modification (if
applicable).
Unauthorized access to change the valve wiring interface,
replace parts, change device hardware or software should not
be permitted. Failure to do so may pose a safety risk.
A tamper evident label has been placed inside the valve
electrical enclosure to indicate if access has occurred. The
label resides between the valve main electronics assembly
and the electrical enclosure which houses it.
NOTE: The valve main electronics assembly is field
replaceable and as such, this seal must be broken in
order to replace it.
2Installation and Mounting

WARNING
Explosion Hazard and Electrical Shock Hazard.
Can cause explosion, serious injury or death.
• Do not take valve apart.
• Do not use tools to operate valve.
• Do not use valve if it has been flooded.
• Call serviceman if valve does not work properly.
IMPORTANT
•Disassembly of the valve in the field may cause permanent
damage to the valve and void the factory warranty.
•Fasteners containing lacquer paint indicate non-field
accessible areas.
•Accessory modules may be removed or replaced as
necessary in the field.
CAUTION
If valve has been dropped, do not use it.
• Dropping the valve may cause permanent damage to the
valve.
• Replace entire valve and associated modules before use.
CAUTION
The SV2 Series valve should be used with clean gas free of
particles bigger than 50 micrometers.
To ensure this requirement is met, an external filter element,
such as the Honeywell Kromschroeder GFK or similar, can
be added to the gas supply line.

Fig. 15. FARMOD pulse line connections/mounting
IMPORTANT
–The Fuel/Air Ratio Module operates properly only if the
pulse line fittings are properly tightened and the flow
through the pulse lines is un-obstructed.
•Proper measures shall be taken to ensure the pulse
lines are not twisted or kinked during connection and
that they can’t be unintentionally kinked after the
installation has been taken into operation.
•Protect pulse lines against damage and keep the lines
free from any contact to potential vibrating surfaces
–In all cases, avoid creating a siphon-like shape.
–A wide variety of pulse line slopes and shapes may be
needed to fit into a particular appliance; best engineering
practice would be ‘1/2 bubble’ on a level (¼ inch of drop
per 1 foot of run or 6mm drop per 0.31m of run). However,
practical limitations may require some deviation from it.
Please consult Honeywell Thermal Solutions with your
particular geometrical arrangement if at doubt.
DO NOT USE.
Fig. 16. V2MU mixing unit pulse line connections.
IMPORTANT (Refer to Fig. 16)
–To avoid condensate from back draft entering any pulse
line of the Fuel/Air Ratio Module, downwards pointing
pressure tabs on the V2MU mixing unit or any other
device shall not be used.

SV2 Series Safety Shut-off Valves

–Partial blockage of the air intake of the V2MU mixing unit
can potentially influence the air pressure signal to the
valve.
•Proper measures shall be taken to avoid a partial air
intake blockage of the V2MU mixing unit. Inspection
of the V2MU air intake shall be part of the annual
maintenance of the appliance.
Premix Air Pre-Filter
IMPORTANT
–The filter should be mounted as close to the valve
FARMOD as possible.
–Replacement of the filter shall be included in the annual
appliance maintenance procedures.

FARMOD insulation.
Premix Outdoor Air Installations
WARNING
Direct water ingress (e.g. from mist, rain or pressure wash)
into the pulse lines should be avoided or prevented
IMPORTANT:
–When the valve is installed in an area with a temperature
continuously lower than the combustion air intake
temperature, a risk of condensate formation in the air
pulse line is present, which can affect the fuel/air ratio
control, depending on the appliance and permanently
damage the FARMOD and the system.
–In this case it is strongly recommended to install the
Honeywell SV2 Series HEATEXCHANGER-000 kit for a
complete condensation/dehumidification solution to
avoid permanent damage to the FARMOD and the system.
–When using the Honeywell HEATEXCHANGER-000 kit,
the valve + FARMOD may be installed above or below the
mixing unit + Heat Exchanger, but above is preferred.
–If the potential for condensation exists and the full
Honeywell dehumidification system is not used,
Honeywell cannot provide any guidance regarding the
valve/FARMOD position versus the mixing unit as this
configuration has not been designed or tested.
–To prevent condensation formation due to back draft, it is
recommended to purge the application after each burner
operation.
–If there is never a risk of condensation, meaning the
ambient room temperature is above the combustion air
dew point at all times, the complete dehumidification
system is not needed. In this case the valve + FARMOD
can be mounted above or below the mixing unit.
Premix Start-Up
IMPORTANT:
–The FARMOD (Fuel/Air Ratio Module) is standard
equipped with a heating device. The heater will be
powered whenever the valve electronics are powered. The
FARMOD will feel warm after 1 hour of being powered.
This is normal.
–As part of the appliance adjustments during
commissioning, the site-specific calibration of the
SV2 Series valve/appliance should be performed when
the valve/appliance has reached a typical operating
temperature for its installation/application in order to
minimize the impact of component temperature changes
on the fuel/air ratio.
