WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause serious injury or property damage. Refer to this manual.
For assistance or additional information, consult a qualified installer or service agency.
WARNING
If the information in these instructions is not
followed exactly, a fire or explosion may result
causing property damage, personal injury or
death.
WARNING
Do not install on combustible flooring. Install
in accordance with all local codes. In the
absence of local codes, refer to NFPA 31 or
ANSI Z21.10.1.
CAUTION
The recommended temperature for normal
residential use is 120°F. The dial on the aquastat
does not always reflect the out-coming water
temperature and it could occasionally exceed
120°F. Variation in out-coming temperature
could be based on factors including but not

which injury occurs vary with the person’s age
and the length of exposure. The slower reaction time of children, elderly or physically or
mentally challenged persons increases the
scalding hazard to them. It is recommended
that lower water temperatures be used where

WARNING
Flammable vapors may be drawn to this water
heater from other areas of the structure by air
currents. Do not store or use any flammable

WHEN YOU RECEIVE YOUR NEW WATER HEATER
Check the new equipment to see if all components are in good condition and were not
amaged in shipment. The water heater and burner may be shipped as separate units. The
d
aquastat and immersion well are packed with the burner. If damage is observed or parts
ppear to be missing, contact your wholesaler.

FLUE OUTLET PLACEMENT AND INSTALLATION
Flue outlet placement is of utmost importance for maximizing the performance of your Bock
Balanced Combustion System (BCS). Please see page 13 for unit dimensions. The following
instructions are recommended and may be code mandated for BCS installation:
n The wall opposite to prevailing winds
(east or south wall, if prevailing winter
winds are typically out of the west or
north) is the preferred wall for installation. This reduces the likelihood that
the Balanced Flue
operating against high winds and
severe cold when it is cycling the
most often.
n The flue outlet must be placed at least
one (1) foot above the highest anticipated snow load to prevent flue
blockage.
™
application will be
n Use a flat wall for the flue outlet and
stay a minimum of three feet from corners or any structure to reduce eddy
currents.
n The flue outlet should be located even
with or above the top of the water
heater and in a location requiring the
fewest inlet and outlet elbows possible.
n To reduce frosting effects, place the out-
let as far as possible from windows,
doors and other structural openings
such as eave vents—four feet is the recommended minimum.
n A minimum distance of three feet from
the outlet to plants and shr
gested; a greater distance is preferred, as
moisture and frost effects can result in
damage or loss.
n The Balanced Flue should be located
away from high traffic areas to prevent
damage to wall outlet and human contact with the hot exhaust sur
ubs is sug
faces.

the assembly to the inside wall with

inner rim of the flashing ring to
prevent moisture from entering
through the wall.
Installation Detail
WATER HEATER PLACEMENT
NOTE: Locate the heater so it is not subject to physical
damage from moving vehicles or flooding.
DO NOT INSTALL THE WATER HEATER ON COMBUSTIBLE FLOORING. Place on noncombustible
flooring and maintain clearances prescribed by this
manufacturer and per code NFPA 31. If the water heater
must be located on combustible flooring it should be
raised off the floor with a layer of 4" concrete block laid
so the air holes are aligned as shown in the drawing at
left. Please contact Bock Water Heaters or consult NFPA
31 with questions concerning proper flooring materials.
Leave adequate room for periodic maintenance of
heater and burner. The heater should be placed as near to the Balanced Flue as convenient in
order to keep vent connector length to a minimum, with a maximum horizontal run length of
15 feet.
Minimum clearance to combustible construction is: SIDES 6"; BACK 6"; FRONT 24". The installation
of this water heater must conform with local codes and ordinances. In the absence of local
codes, the installation must comply with the National Fir
otection Association (NFP
e Pr
A 31) Code.

CONNECT WATER PIPING
Be careful not to apply any heat to the water heater nipples. Install dielectric unions and shut
ff valves on both hot and cold water lines.
o
An approved pressure and temperature relief valve is factory installed in the opening provided
in the upper right-hand side of the water heater. Pipe the T&P to within 6" of the floor or to a
floor drain with a free flowing drain pipe.
CAUTION: Scalding injury and/or water damage can occur from either the manual
lifting of the lever or the normal operation of the T&P valve if it is not piped to a proper
drain. If the valve fails to flow water or reseat, call your plumber.
Check incoming water line for backflow preventers or water pressure reducing valves, as these
may cause pressure to build up in the water heater and result in tank failure. If this water
heater is installed in a closed system or if backflow preventers and pressure regulators are
installed, a properly sized expansion tank must be installed.
40 BCS models are equipped with a brass inlet bushing installed in the tank. Heaters equipped with this bushing are
marked next to the inlet by the decal shown on the left.
he purpose of this bushing is to help keep the tank bot-
T
tom free of sediment by aiding tank flushing. This bushing must be located as shown on the decal to function
properly. Do not allow the bushing to rotate out of position when tightening the inlet fittings.
Note: Do not try to heat hard water as this will drastically reduce heater life. Install a water
softener if the water heater is being installed in a hard water area (water hardness higher than
seven grains).
EXHAUST VENT
Where clearances to combustibles are a concern use double wall venting. Venting approved for Category III applicances is ideal but not required, single wall venting may be used
if allowed by local code. Caution: Do not use B-vent. The vent connector from the heater to
the rear of the Balanced Flue should be made using galvanized or stainless (preferred) vent material with a 4'' minimum diameter. A 6" × 4" reducer is placed on top of the heater flue. Note:
For 190E-BCS, a 6" vent pipe is preferred. Use one elbow to connect the heater to the venting.
An additional elbow may be used if the maximum horizontal distance from the BCS outlet to
the heater is reduced three feet. Maximum horizontal distance is 15 feet.
Venting from the heater to the Balanced Flue should be sealed but does not have to be pressure
tight. High temperature stainless sealing tape (2" wide) or high temperature (+500°F) RTV silicon sealants are recommended. Make certain the flue connector is removable for servicing.
