FORWARD

The design of the WR430-3K complies with CAN 1-4.3 and ANSI Z21.10 (latest edition) as an instantaneous gas water heater. In addition, the WR400-3K also complies with CAN 1-2.17 for use at high altitudes, 2,000 - 4,500 ft. above sea level.

Installation, operation and maintenance instructions are provided in this manual. Installation and operation instructions should be thoroughly reviewed before proceeding with installation of the BOSCH instantaneous gas water heater.

The BOSCH instantaneous gas water heater is designed to operate on natural or propane gas: however, make sure that gas on which heater is to operate is the same as specified on the heater’s model/rating plate.

In addition to these instructions, the water heater shall be installed in accordance with CAN/CGA-B149 Installation Code (in Canada) or Z223.1-latest edition, National Fuel Gas Code (in U.S.A.) and/or local installation codes. These shall be carefully followed in all cases.

INSTALLATION INSTRUCTIONS

The Bosch WR430-3K is a high efficiency fin tube heater and should not be installed and operated during construction or building renovations if location is exposed to above normal dust levels. This can cause dust build up in the finned heat exchanger and result in damage to heater and be a hazard to health.

Note: Proper plumbing, venting, gas connections and an adequate supply of combustion air are required for safe and reliable operation. Ability equivalent to that of a licensed tradesman in the field involved is required for installation and/or service of these water heaters.

LOCATION

Before installing the BOSCH instantaneous gas water heater, consideration must be given to proper location. The location should be as close to outside vent termination as practicable, in an area with an adequate air supply and as centralized with the piping system as possible. The heater should not be located in an area where it will be subject to freezing. The heater should be located in an area where leakage of the heater or its connections will not result in damage to the area adjacent to the heater or to lower floors of the structure. See venting page 5.

Note: When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the water heater. The pan must not restrict combustion air flow.

ELECTRICAL

A grounded switched plug receptable must be provided immediately below the left hand corner of heater to accept and provide power to supplied 3 ft. (0.9m) appliance cable and plug.

AIR REQUIREMENTS

For safe operation, sufficient air for combustion, ventilation and dilution of flue gases must be available. An insufficient supply of air will result in a yellow luminous burner flame, causing carboning or sooting of the heat exchanger.

In order to prevent corrosion, make sure that the combustion air is kept free of aggressive substances. Substances that especially contribute to corrosion are halogenated hydrocarbons (e.g., chlorine and fluorine) which are contaned in solvents, paint, adhesives, propellant gases, various household cleaners, etc. Take precautionary measures as necessary.

In unconfined spaces, in buildings of normal construction, infiltration normally is adequate to provide air for combustion, ventilation and dilution of flue gases. However, a confined space must be provided with two permanent openings to provide combustion and ventilation air to the appliance. Each opening shall have a free area of one square inch per 1,000 Btu/Hr* of total input rating of all the appliances in the enclosure. One opening shall be within 12 inches of the top and one within 12 inches of the bottom of the enclosure.

* Special Note

When the WR430-3K is installed in a confined space of minimum size the openings described above must be increased in to a size of 1-1/2 square inches per 1,000 BTU/Hr. In other words, when installed in a minimum sized confined space the two openings that are to be made in the enclosure within 12 inches of the top and 12 inches of the bottom must each have a minimum free area of, (1-1½” - 2" x (130) = 195 square inches.
