5 - INSTALLATION - Location
5.1.2 - Location of water
heater
When locating the water heater the
following factors must be considered:

location of the openings for the
ventilation of the boiler room
regardless whether the combustion
air is taken from the outside (Direct
Vent, sealed combustion) or inside
(room air for combustion).;

the location of vent/air intake
terminals;

connection to the gas supply;

connection to the cold water inlet;

connection to the water supply;

connection to the electrical supply;

disposal of the condensation
produced by the heater;

piping of the safety P-T relief valve
discharge;

If flooding is possible, elevate the
appliance sufficiently to prevent
water from reaching the unit.
WARNING!!!
Under no
circumstances should the
equipment room ever be under
negative pressure. Particular
care should be taken where
exhaust fans, attic fans, clothes
dryers, compressors, air
handling units, etc., may take
away air from the unit.
Failure to follow this warning
could result in excessive levels
of carbon monoxide, wich can
cause severe personal injury or
death.
WARNING!!!
EXHAUST
FANS: Any fan or equipment
which exhaust air from the
equipment room may deplete the
combustion air supply and/or
cause a downdraft in the venting
system. spillage of flue products
from the venting system into an
occupied living space can cause
a very hazardous condition that
must be immediately corrected.
Failure to follow this warning
could result in excessive levels
of carbon monoxide, wich can
cause severe personal injury or
death.
WARNING!!!
The
combustion air supply must
be completely free of any
flammable vapors that may
ignite or chemical fumes
wich must be avoided are
fluorocarbons and other
halogenated compounds,
most commonly present as
refrigerants or solvents, such
as Freon, trichlorethylene,
perchlorethylene, chlorine, etc.
These chemicals, when burned,
form acids which quickly attack
the heat exchanger tubes,
headers, flue collectors, and the
vent system.
The result is improper combustion and
premature appliance failure.
5.1.1 - Prevent
combustion air
contamination
Do not terminate vent/air in locations
that can allow contamination of
combustion air.
WARNING!!!
Contaminated
combustion air will damage the
heater, resulting in possible
severe personal injury, death or
substantial property damage.
Ensure that the combustion air will
not contain any of the following
contaminants.
Products that may contaminate the air
combustion:
- Permanent wave solutions;
- Chlorinated waxes/cleaners;
- Chlorine-based swimming pool
chemicals;
- Calcium chloride used for thawing;
- Sodium chloride used for water
softening;
- Refrigerant leaks;
- Paint or varnish removers;
- Hydrochloric acid/muriatic acid;
- Cements and glues;
- Antistatic fabric softeners used in
clothes dryers;
- Chlorine-type bleaches, detergents,
and cleaning solvents found in
household laundry rooms;
- Adhesives used to fasten building
products and other similar products;
Do not pipe combustion air near
sources of products that may
contaminate the air combustion, like:
-Dry cleaning/laundry areas and
establishments;
- Swimming pools;
- Metal fabrication plants;
- Beauty shops;
- Refrigeration repair shops;
- Photo processing plants;
- Auto body shops;
- Plastic manufacturing plants;
- Furniture refinishing areas and
establishments;
- Remodeling areas;
- Garages with workshops.
