1.5. Recommended Clearances
The EXALT is approved for zero clearance to combusti-
bles, excluding vent and boiler piping.
• Boiler piping must be a minimum 1/4 inch from
combustible materials.
• Reference the EXALT Vent Supplement for vent
pipe clearance requirements.
It is recommended that the following clearances
be maintained for serviceability:
• 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]
When maintaining less than recommended
service clearances, some product labeling,
including the rating label, may become hidden
and unreadable.
• If the recommended clearances listed above
cannot be maintained or the enclosure in
which the boiler is installed is less than 70
cubic feet, the space must be ventilated.
See Section 2.2 on page 6.
• When installing the EXALT in a confined space,
sufficient air must be provided 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 / ANSI
Z223.1)
• Failure to comply with these instructions
can result in substantial property damage,
serious injury, or death.
