• Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
•
Do obtain new warning and instruction labels for placement
on the blanket directly over the existing labels.
•
Do inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion air flow.
INSTALLATION
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES
ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN
THE FIELD INVOLVED. PLUMBING, ELECTRICAL, AIR SUPPLY,
VENTING AND GAS SUPPLY ARE REQUIRED.
GENERAL
MAKE SURE that the gas supply where this water heater will be
installed is the same as that stated on its model and rating plate.
The installation must conform to these instructions and the local
code authority having jurisdiction. In the absence of local codes,
the installation must conform to the latest edition of National Fuel
Gas Code ANSI Z223.1/NFPA 54 and the National Electric Code,
NFPA 70. The former is available from the Canadian Standards
Association, 8501 East Pleasant Valley Road, Cleveland, OH
44131, and both documents are available from the National Fire
Protection Association, 1 Batterymarch Park, Quincy, MA 02269.
GROUNDING
The water heater, when installed, must be grounded in
accordance with local codes, or in the absence of local codes:
In the United States
The National Electric Code, ANSI/NFPA 70.
HIGH ALTITUDE INSTALLATION
CAUTION
INSTALLATIONS ABOVE 2000 FT. REQUIRE REPLACEMENT OF
THE BURNER ORIFICE IN ACCORDANCE WITH THE NATIONAL
FUEL GAS CODE (ANSI Z223.1/NFPA 54). FAILURE TO REPLACE
THE ORIFICE COULD RESULT IN IMPROPER AND INEFFICIENT
OPERATION OF THE APPLIANCE, PRODUCING CARBON
MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD
RESULT IN SERIOUS PERSONAL INJURY OR DEATH. CONTACT
YOUR GAS SUPPLIER FOR ANY SPECIFIC CHANGES WHICH
MAY BE REQUIRED IN YOUR AREA.
SOME MODELS ARE BUILT SPECIFICALLY FOR HIGH ALTITUDE
SERVICE.
PLEASE CHECK THE RATING PLATE BEFORE MAKING CHANGES.
LOCATION OF HEATER
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the outside wall to
be used for terminations as practicable with adequate air supply and
as centralized with the water piping system as possible.
The heater is design certified by the Underwriter's Laboratory for
installation on combustible flooring in a closet having minimum
clearances from combustible material of: 0" clearance from sides
and rear, 5" from the front and 12" from the top. (Standard clearance.)
If clearances stated on the heater differ from standard clearances,
install water heater according to clearances stated on heater.
A minimum clearance of 4" must be allowed for access to replaceable
parts such as the thermostats, drain valve and relief valve. A top
clearance of 24" should be allowed for blower assembly service.
Adequate clearance for servicing this appliance should be considered
before installation, such as changing the anodes, etc. Minimum
clearances for proper operation are given above.
WARNING
In cold climates provide protection against freeze-up.
THE HEATER SHOULD BE LOCATED IN AN AREA WHERE
LEAKAGE OF THE TANK OR CONNECTIONS WILL NOT RESULT
IN DAMAGE TO THE AREA ADJACENT TO THE HEATER OR TO
LOWER FLOORS OF THE STRUCTURE. When such locations
cannot be avoided, a suitable drain pan should be installed under
the heater, see fig. 1. The pan must not restrict combustion air
flow. Such pans should have a minimum length and width of at
least 2 inches greater than the diameter of the heater and should
be piped to an adequate drain. Drain pans suitable for these
heaters are available from your dealer.
Installation of the water heater must be accomplished in such a
manner that if the tank or any of the connections should leak, the flow
will not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an attic or upper floor. When
such locations can not be avoided, a suitable drain pan should be
installed under the water heater.
Drain pans are available at your local hardware store. Such a drain
pan must have a minimum length and width of at least 2 inches (51
mm) greater than adequate drain. The pan must not restrict
combustion air flow.
Water heater life depends upon water quality, water pressure and the
environment in which the water heater is installed. Water heaters are
sometimes installed in locations where leakage may result in property
damage, even with the use of a drain pan piped to a drain. However,
unanticipated damage can be reduced or prevented by a leak detector
or water shut-off device used in conjunction with a piped drain pan.
These devices are available from some plumbing supply wholesalers
and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or turn off
the incoming water to the water heater when leakage is detected.
• Sensors mounted in the drain pan that turn off the water supply to
the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water pipes
connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater while
at the same time shutting off its water supply.
WARNING
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 (76.2mm) in
any direction. If the heater is installed in a carpeted alcove or
closet, the entire floor shall be covered by the panel.
AIR REQUIREMENTS
In calculating the free area of a vent opening, the blocking effect of
screens, louvers and grills should be considered. Screens shall
not be of a mesh smaller than 1/4 inch square. If the free area is
