TriangleTube 399 Solo - Manual (Page 10)

Pre-Installation Items
- 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 zero clearance or less
than recommended clearances, some
product labeling may become hidden
and unreadable.
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 boiler control has a freeze protection feature
built in. This feature monitors the boiler temper-
ature and responds as follows when no call for
heat is present:
- 46ºF Boiler circulator is ON
- 38ºF Boiler circulator is ON and burner
operates at low fire
- 50ºF Burner OFF and boiler circulator
operates for approximately 10 minutes
The boiler freeze protection feature is
disabled during a hard lockout, however
the CH circulator 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 IX
for antifreeze guides.
