Locating The Water Heater; Clearances - Lochinvar CLN 120080 Instruction Manual

LOCATING THE WATER HEATER

CAUTION
Property Damage Hazard
•
All water heaters eventually leak.
•
Do not install without adequate drainage.
When installing the heater, consideration must be given to
proper location. Location selected should be as close to the
stack or chimney as practicable, with adequate air supply and as
centralized with the piping system as possible.
Fire or Explosion Hazard
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
Avoid all ignition sources if you smell gas.
Do not expose water heater controls to excessive gas
pressure.
Use only the gas shown on the water heater rating label.
Maintain required clearances to combustibles.
Keep ignition sources away from faucets after extended
periods of non-use.
Read instruction manual before
installing, using or servicing
water heater.
There is a risk in using fuel burning appliances such as gas
water heaters in rooms, garages or other areas where gasoline,
other flammable liquids or engine driven equipment or vehicles
are stored, operated or repaired. Flammable vapors are heavy
and travel along the floor and may be ignited by the heater's
igniter or main burner flames causing fire or explosion. Some
local codes permit operation of gas appliances in such areas if
they are installed 18" or more above the floor. This may reduce
the risk if location in such an area cannot be avoided.
Do not install this water heater directly on a carpeted floor.
A fire hazard may result. Instead the water heater must be
placed on a metal or wood panel extending beyond the full
width and depth by at least 3 inches in any direction. If the
heater is installed in a carpeted alcove, the entire floor shall
be covered by the panel.
The heater shall be located or protected so it is not subject to
physical damage by a moving vehicle.
Flammable items, pressurized containers or any other
potential fire hazardous articles must never be placed on
or adjacent to the heater. Open containers or flammable
material should not be stored or used in the same room with
the heater.
The heater must not be located in an area where it will be
subject to freezing.
Locate it near a floor drain. The heater should be located in
an area where leakage from heater or connections will not
result in damage to adjacent area or to the lower floors of
the structure.
When such locations cannot be avoided, a suitable drain pan
should be installed under heater. Such pans should be fabricated
with sides at least 2" deep, with length and width at least 2" greater
than diameter of heater and must be piped to an adequate drain.
Pan must not restrict combustion air flow.

CLEARANCES

This water heater is approved for installation on combustible
flooring in an alcove with minimum clearance from combustion
construction as indicated in Figure 7 and Table 4.
In all installations the minimum combustible clearances from
vent piping shall be 6" (15.2 cm). Vent piping passing through a
combustible wall or ceiling must be a continuous run (no joints)
and retain 6" (15.2 cm) clearance unless an approved reducing
thimble is used.
When the water heater is installed directly on carpeting, the water
heater shall be installed on a metal or wood panel extending
beyond the full width and depth of the water heater by at least
3 in (76.2 mm) in any direction or, if the water heater is installed
in an alcove or closet, the entire floor shall be covered by the
panel. The panel must be strong enough to carry the weight of
the heater when full of water.
A service clearance of at least 24" (61 cm) should be maintained
from serviceable parts.
