FAILURE TO FOLLOW THESE WARNINGS
COULD RESULT IN FIRE, PROPERTY
DAMAGE, PERSONAL INJURY, OR DEATH.
When vent pipe is exposed to temperatures
below freezing, such as when it passes through
an unheated space or when a chimney is used
as a chaseway, vent pipe must be insulated
with l/2"Armaflex or equivalent. In extremely
cold climate areas, use 3/4"Armaflex or
equivalent.
Combustion air must be clean outdoor air.
Combustion air must not be taken from inside
the structure because that air is frequently
contaminated by halogens, which include
fluorides, chlorides, phosphates, bromides
and iodides. These elements are found in
aerosols, detergents, bleaches, cleaning
solvents, salts, air fresheners, paints,
adhesives, and other household products.
Locate combustion air inlet as far away as
possible from swimming pool and swimming
pool pump house. All combustion air and
vent pipes must be airtight and watertight.
Combustion air and vent piping must also
terminate exactly as shown in Figures 1-2. If
a concentric vent termination is being used,
refer to Figures 3-5 for proper setup.
Vent connections serving appliances vented
by natural draft shall not be connected into any
portion of mechanical draft systems operating
under positive pressure.
Solvent cements are combustible. Keep away
from heat, sparks, or open flame. Use only in
well ventilated areas. Avoid breathing in vapor
k.or allowing contact with skin or eyes. J
