EXHAUST INDUCER (BLOWER ASSY.)

All SBN 120-400 models are equipped with an exhaust inducer.
The inducer assists in drawing in fresh air to the unit for
combustion and then assists in dispensing the combustion by-
products into the venting leading outside.
The exhaust inducer is equipped with a gravity controlled damper
to reduce the amount of heat loss through the flue, improving
efficiency.

CIRCULATING PUMP

A circulating pump is used when a system requires a circulating
loop or there is a storage tank used in conjunction with the
heater. Refer to the piping diagrams in this manual for electrical
hookup information and install in accordance with the latest
version of the National Electric Code ANSI/NFPA No. 70.
Only all bronze circulators are used with commercial water
heaters.
Although circulators are oiled and operated by the manufacturer
some circulators must be oiled again before operating. Please
refer to manufacturer's instructions.

DISHWASHING MACHINE REQUIREMENT

These appliances meet the National Sanitation Foundation
Standard for sanitary installations when used with the following
leg kit, Part No. 6570-7.
All dishwashing machines meeting the National Sanitation
Foundation requirements are designed to operate with water
flow pressures between 15 and 25 psi. Flow pressures above
25 psi, or below 15 psi, will result in improperly sanitized dishes.
Where pressures are high, a water pressure reducing or flow
regulating control valve should be used in 180
dishwashing machine, and should be adjusted to deliver water
between these limits.
The National Sanitation Foundation also recommends
circulation of 180 F (82.2°C) water. Where this is done, the
0
circulation should be very gentle so that it does not cause any
unnecessary turbulence inside the water heater. The circulation
should be just enough to provide 180
point of take-off to the dishwashing machine. Adjust flow by
means of the plug cock in the circulating line.

INSTALLATION INSTRUCTIONS

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE
REQUIRED.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.

UNCRATING

The heater is shipped with the inducer already installed. The
wiring conduit runs from the thermostat to the inducer. Before
turning unit on, check to make sure the wiring conduit is securely
plugged into the inducer.

LOCATING THE HEATER

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.
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 PILOT 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.
