OUTDOOR STAND
This rooftop water heater is approved for an outdoor installation
with an optional stand. Contact State Order Entry to acquire
optional stand kit.
The rooftop stand is constructed of a tubular steel frame along
with tubular steel legs. See Figure 32. The legs are three feet in
length and slide into the corners of the tubular steel frame. The
legs may be cut to length to reduce the overall height of the stand
if necessary.
The rooftop unit is located on the stand the same way as located
on the roof curb. Please locate panels at one end of the stand.
This area is used to run the water lines into the rooftop unit. It
provides added protection to the water lines. For additional
information see Optional Stand Kit Instructions.
FIGURE 32
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the intake and
exhaust termination points as practicable, with adequate air supply
and as centralized with the piping system as possible.
LOCATE IT NEAR A DRAIN. THE HEATER SHOULD BE LOCATED
IN AN AREA WHERE LEAKAGE FROM THE HEATER OR
CONNECTIONS WILL NOT RESULT IN DAMAGE TO THE
ADJACENT AREA OR TO LOWER FLOORS OF THE STRUCTURE.
When such locations cannot be avoided, it is recommended that a
suitable drain pan, adequately drained, be installed under the
appliance.
State Water Heater provides an after market anti-freeze kit for use
when there is a loss of power. This kit provides drainage to the
tank and plumbing manifold to prevent freeze-up. When power is
restored, the system is equipped with automatic air bleed and a
low-water cut-off device to prove the tank is full of water prior to
startup. See kit instructions for complete details.
WARNING
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDER
WATER. IMMEDIATELY CONTACT A QUALIFIED INSTALLER OR
SERVICE AGENCY TO REPLACE A FLOODED WATER HEATER.
DO NOT ATTEMPT TO REPAIR THE UNIT! IT MUST BE REPLACED!
CLEARANCES
These heaters are approved for outdoor installations on
combustible flooring (roof) with the minimum clearances of 0" for
sides and 1.50" for top.
Always disconnect electrical power before servicing the unit.
HARD WATER
Where hard water conditions exist, water softening or the
threshold type of water treatment is recommended. This will
protect the dishwashers, coffee urns, water heaters, water
piping and other equipment.
See MAINTENANCE section for details of tank cleanout procedure.
AIR REQUIREMENTS
KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE
MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND
LIQUIDS.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR.
WARNING
FOR SAFE OPERATION PROVIDE ADEQUATE AIR FOR
COMBUSTION AND VENTILATION. AN INSUFFICIENT SUPPLY OF
AIR WILL CAUSE RECIRCULATION OF COMBUSTION
PRODUCTS RESULTING IN CONTAMINATION THAT MAY BE
HAZARDOUS TO LIFE. SUCH A CONDITION OFTEN WILL RESULT
IN A YELLOW, LUMINOUS BURNER FLAME, CAUSING
CARBONING OR SOOTING OF THE COMBUSTION CHAMBER,
BURNERS AND FLUE TUBES AND CREATES A RISK OF
ASPHYXIATION.
CHEMICAL VAPOR CORROSION
WARNING
CORROSION OF THE FLUE WAYS AND VENT SYSTEM MAY
OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN
CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN
FAILURE AND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium and
sodium chloride, waxes, and process chemicals are typical
compounds which are potentially corrosive.
PRODUCTS OF THIS SORT SHOULD NOT BE STORED NEAR
THE HEATER. ALSO, AIR WHICH IS BROUGHT IN CONTACT WITH
THE HEATER SHOULD NOT CONTAIN ANY OF THESE
CHEMICALS. IF NECESSARY, UNCONTAMINATED AIR SHOULD
BE OBTAINED FROM REMOTE OR OUTSIDE SOURCES.
