SECTION 2.

Installation Instructions

2A. General Information

Install the Laars Lite 2 heaters, vent caps and drafthoods in accordance with the procedures in this manual, local codes and ordinances, and in accordance with the latest edition of the National Fuel Gas Code, ANSI Z223.1. In Canada, the installation must be in accordance with CAN1-B149.1 or .2 and local codes. The authority having jurisdiction may require that the installation conform to the Standard for Gas-Fired Heaters, ANSI Z21.56. Any changes to the heater, gas controls, gas orifices, wiring, draft diverter, or im- proper installation may void the warranty. If field conditions require change to any of the above, consult the factory.

All gas-fired products require correct installation to assure safe operation. The requirements for pool heaters include the following:

1.Field assembly (if required)

2.Appropriate site location (clearances) and flooring

3.Sufficient combustion and ventilation air

4.Properly sized gas meter and piping

5.Proper electrical wiring (if required)

6.Adequate water flow

This manual provides the information needed to meet these requirements. Review all application and installation procedures completely before continuing the installation.

2B. Field Assembly

The Laars Lite 2 heater is shipped from the factory with the top assembly in the low-profile configuration for outdoor installation in the U.S. In Canada, an outdoor installation requires the addition of a factory approved vent cap. The Laars Lite 2 heater is design certified for indoor installation when equipped with a drafthood, which must be installed without modification.

The Laars Lite 2 heater is also certified for installation in an outdoor shelter in Canada when equipped with a drafthood. An outdoor shelter is an enclosure not normally occupied which does not communicate directly with occupied areas.

Check the rating plate on the heater or the Parts List (Sec. 4) of this manual for the correct Waterpik Laars drafthood or vent cap part number. See instruc- tions supplied with the drafthood or vent cap for installation and attachment. When the drafthood is used, locate the heater so as to be in the same atmo- spheric pressure zone as the combustion air inlet to the heater.
