Bradford White UCG100H199 Installation & Operation Manual page 9

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 National Fuel Gas Code (ANSI Z233.1- latest edition) or in Canada The Natural Gas Installation Code
CAN/CGA (B149.1 - latest edition), expressly prohibits the following:
a. Installation of a water heater in a bathroom, bedroom, or any occupied room normally kept closed.
b. Installation of a water heater in a garage, unless the unit is installed so that the burner and ignition devices are at
least eighteen (18) inches (45.8 cm) above floor level and protected to avoid damage by a moving vehicle.
If the buildings cold water supply has a back-flow preventer, check valve or water meter with check valve, provisions
for thermal expansion of water in the hot water system must be provided.
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 Operating 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 three (3) inches (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 inches 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. All equipment is carefully manufactured, inspected and packed.
3. Any claims for damage or shortage in shipment must be filed immediately with the manufacturer noted on the
rating plate label.
LOCATE WATER HEATER
1. Locate 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.
4. 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 Operating Instructions.
5. 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.
6. Increase distances to provide clearance for servicing.
