Recommended Clearances

The PRESTIGE Solo is approved for zero
clearance to combustibles, excluding vent and
boiler piping.
- Boiler Piping - 1/4 inch from com-
bustible materials.
- Reference the appropriate vent supple-
ment for clearance requirements.
BEST PRACTICE
To provide serviceability to the unit it is
recommended that the following clear-
ances be maintained:
Top boiler jacket - 24 inches [610 mm].
Front - 24 inches [610 mm].
Bottom boiler piping - 24 inches [610 mm].
Rear - 0 inches
Sides - 6 inches [153 mm]
WARNING
If the clearances listed above cannot be
maintained or the enclosure in which the
boiler is installed is less than 85 cubic feet,
the space must be ventilated. See page 6
for ventilation requirements.
NOTI E
When maintaining less than recom-
mended serviceability clearances, some
product labeling, including the rating
label, may become hidden and unread-
able.
WARNING
When installing the PRESTIGE Solo in
a confined space, sufficient air must be
provided for proper combustion and
venting and to allow, under normal oper-
ating conditions, proper air flow around
the product to maintain ambient temper-
atures within safe limits to comply with
the National Fuel Gas Code NFPA 54 -
latest edition.

Residential Garage Installations

When installing the PRESTIGE Solo in a resi-
dential garage, the following special precautions
per NFPA 54/ANSI Z223.1 must be taken:
- Mount the unit a minimum 18 inches
[458 mm] above the floor level of the
garage. Ensure the burner and ignition
devices / controls are no less than 18
inches [458 mm] above the floor level.
- Locate or protect the unit in a manner so it
cannot be damaged by a moving vehicle.

Boiler Freeze Protection Feature

The ACVMax boiler management system has a
freeze protection feature built in. This feature
monitors the boiler water temperature and
responds as follows when no call for heat is pre-
sent:
- 46ºF [8ºC] Pump outputs configured to
respond to a CH1 Call are enabled.
- 42ºF [6ºC] Pump outputs configured to
respond to a CH1 or CH2 Call are
enabled, Burner operates at low fire.
- 60ºF [15ºC] Freeze protection ends.
Burner & all pumps turn off after com-
pleting CH Post Pump Time.
CAUTION
The boiler freeze protection feature is
disabled during a hard lockout, however
the circulators will operate.
CAUTION
The boiler freeze protection feature is
designed to protect the boiler. The boiler
should be installed in a primary/sec-
ondary piping arrangement if it is
installed in an unheated space or
exposed to water temperatures of 46ºF or
less. See Section IV for primary/sec-
ondary piping examples. See Section X
for antifreeze guides.
