General Information

IMPORTANT WARNING:

The MegaTherm Model MT commercial pool boilers must be used with potable water only. For pools containing salt water, a specially equipped boiler must be used. Consult your distributor or factory representative. The pool boiler must be installed in accordance with the procedures in this manual, or the warranty could be voided. Consult local building codes and ANSI bulletin Z223.1 or in Canada CAN1- B149 before proceeding with the installation. Any modification to the boiler, its gas controls, gas orifices, wiring or draft diverter may void the warranty. Consult the factory before making any modifications.

1A. Introduction

This manual provides information for the installation and operation of Model MT Pool Boilers. It is strongly recommended that all application and installation procedures be reviewed completely before proceeding with the installation. Consult the Pentair Water Commercial Pool and Spa technical support

(see page 2), or your local representative, with any problems or questions regarding this equipment. Experience has shown that most operating problems are caused by improper installation.

Model MT boilers are offered in two configurations: an indoor version and an outdoor version. The indoor version is convertible for outdoor use with the installation of a conversion kit as described in Section 6 of this manual. The two configurations are shown in Figure 1.

Some accessory items are shipped in separate packages. Verify receipt of all packages listed on the packing slip. Inspect everything for damage immediately upon delivery, and advise the carrier of any shortages or damage. Any such claims should be filed with the carrier. The carrier, not the shipper, is responsible for shortages and damage to the shipment whether visible or concealed.
