Bradford White RE2H50S 1NCTT Series Installation/Operation Instruction Manual page 11

Installation Instructions cont.-
Air Exchange Efficiency
Required and recommended minimum clearances listed in this Installation and Operations Manual are for the
optimum performance, efficiency, and serviceability of the water heater.
Installing the water heater in a manner that does not provide sufficient air exchange will result in increased
energy consumption. Ensure that the rear of the water heater is open and not discharged against a wall. A
ducting kit may be required in order to achieve optimum efficiency. Bradford White is not liable or responsible
for any additional energy consumption or warranty implications.
Note: If the air temperature in the installed location drops more than 15˚F (8˚C) during heating, air
circulation is insufficient for optimum operation. Utilize the ducting kit to direct cold exhaust air to another
location.
Recommended Clearances
NOTE: Installations in a confined space, or installations where the
recommended service clearances are not met, will lead to higher
power consumption (increased use of resistance heating elements
and/or heat pump efficiency reduction).
It is recommended to have a 7" (17.5 cm) clearance between
any object and the rear and right side of the water heater in the
event service is needed. A minimum 8" (20.3 cm) clearance
above the water heater to remove the filter for cleaning and for
service access, and clear access to the front of the water heater,
is recommended. Installations that require less than 7" (17.5 cm)
clearance on the right side or rear of the water heater for
earthquake straps are also acceptable (see Minimum Required
Clearances section below for more information). In these cases,
it is recommended to provide additional clearance on the
opposite side of the unit to allow for service access. The hot
and cold water plumbing and electrical connections must not
interfere with the removal of the filter.
If a separate ducting kit is purchased (refer to
www.bradfordwhite.com for ducting kit part number), additional
space is required above and to the rear of the water heater for
installation. Consult the ducting kit manual for specific
instructions. See www.bradfordwhite.com for details.
The clearances shown are recommended for optimal
performance (best possible efficiency) as well as adequate
service room. Reducing these clearances may impact the overall
performance compared to what is displayed on the water heater.
A ducting kit may need to be used – refer to the Service Manual
or ducting kit instructions for installation information.
Insufficient air exchange will result in increased energy
consumption levels.
