This Owner's Manual includes all options and accessories

commonly used on this heater.  However, depending on the

configuration purchased, some options and accessories

may not be included.

When calling for technical service assistance, or for other

specific information, always have model number,

configuration number and serial number available.  This

information is contained on the dataplate.

This manual will instruct you in the operation and care of

your unit. Have your qualified installer review this manual

with you so that you fully understand the heater and how it

functions.

The gas supply line installation, installation of the heater,

and repair and servicing of the heater requires continuing

expert training and knowledge of gas heaters and should

not be attempted by anyone who is not so qualified.  See

page 6 for definition of the necessary qualifications.

Contact your local L.B. White distributor or the L.B. White

Co., Inc. for assistance, or if you have any questions about

the use of the equipment or its application.

The L.B. White Co., Inc. has a policy of continuous product

improvement.  It reserves the right to change specifications

and design without notice.
