General Information

1.1 Introduction

This manual provides information for the

installation and operation of MegaTherm model MT pool heating boilers. It is strongly recommended that all application and installation procedures be reviewed completely before proceeding with the installation. Consult Pentair Commercial Pool and Spa, or your local sales representative, with any problems or questions regarding this equipment. Experience has shown that most problems are caused by improper installation, not system design.

Some accessory items are shipped in separate packages. Verify receipt of all packages listed on the packing slip. Inspect everything for possible damage upon delivery, and inform the carrier of any shortages or impairments. 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.

WARNING

The MegaTherm model MT commercial pool heating boiler must be used on potable water only. For heating pools containing salt water, a specially equipped heater must be used; consult your distributor or factory representative. The pool heating boiler must be installed in accordance with the procedures

The warranty does not apply to heaters not installed or operated in accordance with these procedures. Consult local building and safety codes before proceeding with work. The installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requirements, to the latest edition of the National Fuel Gas Code; ANSI Z223.1, National Electrical Code ANSI/NFPA 70. In Canada, the installation must conform with the latest edition of CSA-B149.1 requirements.

When required by the authority having jurisdiction, the installation must conform to

American Society of Mechanical Engineers safety codes for controls and safety devices for automatically fired heaters No. CSD-1, and in Canada CGA 3.3. Any modification of the heater, its gas controls, gas orifices, wiring or drafter diverter may void the warranty. If field conditions require such modifications, consult factory.

1.2 Heater Identification

Consult rating plate on the heating boiler. Shown below is a breakdown of the model nomenclature. Commercial pool heating boilers are available in two configurations: an indoor version and an outdoor version. Outdoor models are not available in Canada.

1.3 Primary/Secondary Pump and Piping

All models are supplied with integrally mounted pumps. The 1825 models use a 3/4 HP pump and all other models are supplied with 1/2 HP pumps. These pumps are sized for the pressure drop through the heat exchanger and through the bypass piping as shown in Figure 10.

Any deviations from the arrangement shown may increase the head on the pump, reduce flow and hinder performance (see Section 2.7). For spas see Section 3.9.

This piping arrangement and the integral pump allow hot water to be recirculated to the heater inlet, thus raising the inlet temperature and greatly reducing condensation.

1.4 Certifications

All models are design-certified by CSA for natural or propane gas and conform to ASME Code requirement for 160 PSI water pressure.

1.5 Engineering Assistance

Consult the factory or distributor regarding any questions or problems which arise in the specification, installation or operation of this equipment. An experienced engineering staff is ready to assist in assuring the proper performance and application of this products.
