CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.5. Recommended Clearances
The INSTINCT is approved for zero clearance to com-
bustibles, excluding vent and boiler piping.
• Boiler piping must be a minimum 1/4 inch from
combustible materials.
• Reference the INSTINCT 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, in-
cluding the rating label, may become hidden
and unreadable.
• If the recommended clearances list-
ed above cannot be maintained
or the enclosure in which the boil-
er is installed is less than 70 cubic
feet, the space must be ventilated.
See Section 2.2 on page 6.
• When installing the INSTINCT in a con-
fined space, sufficient air must be provided
to allow, under normal operating condi-
tions, 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 dam-
age, serious injury, or death.
