NOTE − Service access clearance must be maintained.

Accessibility and service clearances must take prece- dence over fire protection clearances.

For installation in a residential garage, unit must be lo- cated or protected to avoid physical damage by vehicles.

The CBWMV unit must be installed so that its electrical components are protected from water.

When the CBWMV unit is used with an air conditioner, the air handler shall be installed on the upstream side of the cooling evaporator coil to avoid freeze−up of water system and condensation. With a parallel flow arrangement, a damper (or other means to control the flow of air) must ad- equately prevent chilled air from entering the air handler. If the damper is manually operated, it must be equipped to prevent operation of either the heating or the cooling unit, unless it is in the full HEAT or COOL setting.

NOTE − CBWMV series units must not be used in or for the following applications:

Sconstruction heater − during any phase of construction

Sunit heater

Smobile home heater

Spotable water applications

Application

The CBWMV unit is designed for use in non−potable water boiler systems. The water heating device must be ade- quate to provide enough heat according to the Engineering Handbook specifications. The water heating device must provide a minimum of 6 gallons/minute for small units (CBWMV−040, −070) and 9 gallons/minute for large units (CBWMV−090, −100, −120).

WARNING

This product contains fiberglass wool.

Disturbing the insulation during installation, main- tenance, or repair will expose you to fiberglass wool dust. Breathing this may cause lung cancer. (Fiber- glass wool is known to the State of California to cause cancer.)

Fiberglass wool may also cause respiratory, skin, and eye irritation.

To reduce exposure to this substance or for further information, consult material safety data sheets available from address shown below, or contact your supervisor.

The boiler installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requirements, to the latest revision of the National Fuel Gas Code, ANSI Z223. (Available from the American Gas Association, 8501 E. Pleasant Valley Road, Cleveland, OH 44134). Reference should also be made to local gas utility regulations and other codes in effect in the same area in which the installation is to be made. When installed in Canada: The latest revision of the CAN1/CSA−B149.1 and/or B149.2 Installation Codes for Gas-Burning Equip- ment and/or local codes.

Determine the CBWMV unit installation location and posi- tion units so that door panels are accessible. Keep in mind routing of the water and plumbing lines and electrical con- nections.

The CBWMV unit is multi−positional. No adjustment is nec- essary to apply unit for upflow or horizontal discharge. A downflow base is available and provides clearance for routing the inlet/outlet water lines when the CBWMV unit is applied without an add−on cooling coil. Downflow applica-
