TriangleTube Prestige Excellence Part 1 - Manual (Page 11)

Pre-Installation Items
Recommended Clearances
The PRESTIGE Excellence is approved for
zero clearance to combustibles, excluding
vent and boiler piping.
- Vent & Boiler Piping - 1/4 inch from
combustible materials.
To provide serviceability to the unit it is
recommended that the following clear-
ances be maintained:
Top boiler jacket - 24 inches.
Front - 24 inches.
Bottom boiler piping - 24 inches.
Rear - 0 inches
Sides - 6 inches
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
Excellence in a confined space, sufficient
air must be provided for proper combus-
tion and venting and to allow, under
normal operating conditions, proper air
flow around the product to maintain
ambient temperatures within safe limits
to comply with the National Fuel Gas
Code NFPA 54 - latest edition.
Residential Garage Installations
When installing the PRESTIGE Excellence in a
residential garage, the following special precau-
tions per NFPA 54/ANSI Z223.1 must be taken:
- Mount the unit with a minimum 18
inches above the floor level of the
garage. Ensure the burner and ignition
devices / controls are no less than 18
inches above the floor level.
- Locate or protect the unit in a matter
so it cannot be damaged by a moving
vehicle.
Boiler Freeze Protection Feature
The boiler control has an freeze protection fea-
ture built in. This feature monitors the boiler
temperature 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 and the 3-
way valve will open to the CH system.
The boiler freeze protection feature is
designed to protect the boiler and should
be installed in a primary/secondary pip-
ing arrangement. If it is installed in an
unheated space or exposed to water tem-
peratures of 46ºF or less, see Section IV
for primary/secondary piping examples.
See Section IX for antifreeze guidelines.
