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.
WARNING
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

WARNING
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. 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. Also, see the DRAINING
requirements in MAINTENANCE Section.
THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS NOT
SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE.
WARNING
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.
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.
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 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, A SUITABLE
DRAIN PAN SHOULD BE INSTALLED UNDER THE HEATER. Such
pans should be fabricated with sides at least 2" deep, with length
and width at least 2" greater than the diameter of the heater and
must be piped to an adequate drain. The pan must not restrict
combustion air flow.
For appliance installation locations with elevations above
2000 feet (610m), refer to HIGH ALTITUDE INSTALLATIONS
section of this manual for input reduction procedure.

LEVELING

If the unit is not level, insert the bolts which were used in crating
into the legs to correct this condition.

CLEARANCES

These heaters are approved for installation on combustible
flooring in an alcove when the minimum clearance from any
combustion construction are followed as indicated in figure 6.
Model BTR 151 and 201A is approved for installation on non-
cumbustible flooring or combustible flooring with leg kit part no.
6570.
In all installations the minimum combustible clearances from
vent piping shall be 6". Vent piping passing through a combustible
wall or ceiling must be a continuous run (no joints) and retain
the 6" clearance unless an approved reducing thimble is used.
A service clearance of 24" should be maintained from serviceable
parts, such as relief valves, flue baffles, thermostats, cleanout
openings or drain valves.
The units are approved for installation with side, rear and ceiling
clearances.

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

REFER TO THE LATEST EDITION OF THE "NATIONAL FUEL
GAS CODE" ANSI Z223.1/NFPA 54.
KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE
MATERIALS, GASOLINE AND OTHER FLAMMABLES, VAPORS
AND LIQUIDS.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION OR
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 AIR CONTAMINATION THAT MAY BE
HAZARDOUS TO LIFE. SUCH A CONDITION OFTEN WILL RESULT
IN A YELLOW, LUMINOUS BURNER FLAME, CAUSING
