Bradford White UCG100H199 Installation & Operation Manual page 9

THIS WATER HEATER MUST BE INSTALLED INDOORS OUT OF THE WIND AND WEATHER.
THIS WATER HEATER MUST NOT BE INSTALLED IN ANY LOCATION WHERE GASOLINE OR
FLAMMABLE VAPORS ARE LIKELY TO BE PRESENT, UNLESS THE INSTALLATION IS SUCH TO
ELIMINATE THE PROBABLE IGNITION OF GASOLINE OR FLAMMABLE VAPORS.
The location of this water heater is of the utmost importance. Before installing this water heater, you should
read the Installation section of these instructions. After reading these Installation and Operation Instructions,
select a location for the water heater where the floor is level and is easily accessible to water lines, gas supply
(type identified on the rating plate), an adequate open drain, and a chimney or exhaust gas vent. DO NOT
locate the water heater where water lines could be subjected to freezing temperatures. Make sure the
cold water pipes are NOT located directly above the gas control box or any other electrical control so
that condensate during humid weather does not drip on the controls.
This installation must allow access to the front of the water heater and adequate clearance must be provided
for servicing and operating this water heater. The water heater may be installed on either a combustible or non-
combustible floor. If the water heater is to be installed directly on carpeting, it must be installed on top of a
metal or wood panel (or equivalent) extending beyond the full width and depth of the appliance by at least 3 in
(7.6 cm) in any direction or, if the appliance is to be installed in an alcove or closet, the entire floor must be
covered by the panel. The minimum clearances to combustibles for this water heater are given in the following
pages. A minimum of 24 in (61 cm) front clearance must be provided for inspection and servicing. Adequate
clearances must be provided for easy access to controls by service personnel to enable proper cleaning,
servicing, and operation of the water heater.
Water heater corrosion and component failure can be caused by the heating and breakdown of airborne
chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants,
cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium
chloride, waxes, and process chemicals. These materials are corrosive at very low concentration levels with
little or no odor to reveal their presence
DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY
THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL OCCUR. DO NOT
STORE ANY POTENTIALLY CORROSIVE COMPOUNDS IN THE VICINITY OF THE WATER HEATER.
Unpacking
1. Inspect carefully for any signs of damage.
2. Any claims for damage or shortage in shipment must be filed immediately with the manufacturer noted
on the rating plate label.
Locating the Water Heater
1. Locate the water heater in front of final position before removing crate.
2. Locate so that venting connections will be short and direct.
3. This water heater is suitable for installation on combustible floor. DO NOT install this water heater
directly on carpeting. If the water heater is to be installed on carpeting, it must be installed on top of a
metal or wood panel extending beyond the full width and depth of the appliance by at least three 3 in
(7.6 cm) in any direction or, if the appliance is to be installed in an alcove or closet, the entire floor must
be covered by the panel.
4. For basement installation, provide a solid, level, and elevated base such as concrete or other suitable
pad to raise the water heater at least 3 in (7.6 cm) to provide a slope of 1/4 in/ft (.635 cm/m) for the
condensate line to a suitable drain.
5. Proper venting practices must be considered when selecting a location for this water heater. For exact
venting specifications, please consult the Venting section of these Installation and Operation Instructions
(page 13).
6. It is recommended that minimum clearances shown in Figure 2b be provided on the sides and top of the
water heater for servicing and maintenance of the water heater. Increase distances to provide clearance
for servicing.
