Install Instructions

1.0 Pre-Installation Items
1.4 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.
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]
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.
When maintaining less than recom-
mended serviceability clearances, some
product labeling, including the rating
label, may become hidden and unread-
able.
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.
1.5 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.
1.6 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.
The boiler freeze protection feature is
disabled during a hard lockout, however
the circulators will operate.
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.
