Thermal Expansion - Bradford White RE2H50S-1NCWT Serie Guide Rapide

Installation
LOCATION
The water heater and water lines should be protected from freezing
temperatures and high-corrosive atmospheres. Do not install the water
heater in outdoor, unprotected areas.
CAUTION:
Risk of Property Damage -
water heater should not be located in an area where leakage of
the tank or connections will result in damage to the area
adjacent to it or to lower floors of the structure. Where such
areas cannot be avoided, it is recommended that a suitable
catch pan, adequately drained, be installed under the water
heater.
NOTE: The heat pump operating range is 35°F to 120°F (2°C to 49°C).
If the ambient temperature is outside of this range, the heat pump
will turn off and the electric elements will be used until the ambient
temperature returns to within the operating range.
REQUIRED CLEARANCES:
There must be a 7" (17.5 cm) clearance between any object and the rear
and sides of the water heater in the event service is needed. A minimum 8"
(20.3cm) 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 6" clearance on the sides or rear of
the water heater for earthquake straps are also acceptable. In these cases,
additional clearance must be provided 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, 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.

CATCH PAN INSTALLATION
NOTE: Auxiliary catch pan MUST conform to local codes.
Catch Pan Kits are available from the store where the water heater was
purchased, a builder store or any water heater distributor. The catch pan
should be 2" (5.1 cm) minimum larger than the Water Heater base diameter.
To prevent corrosion and improve Drain Valve access it is recommended that
The
the water heater be placed on spacers inside the catch pan.

THERMAL EXPANSION

If check valve is present on inlet water line, use of a thermal expansion
tank is recommended. Check valves on the inlet water line are referred
to as a "closed system." A closed system can cause the check valve on
the water heater to operate more than intended, causing premature
failure. The suggested method of controlling thermal expansion is to
install an expansion tank in the cold water line between the water
heater and the check valve as shown.
