It is best to handle these preparations before the heater is installed in its final location. Instructions are provided in subsequent sections of this document.
Contact Waterpik Technologies regarding installations at elevations above 3,000 feet (980 m). It is necessary to make changes to the burner tray to assure proper operation.
2C. Heater Location
2C-1. Installation Information
The LX and LT can be installed outdoors or indoors as outlined in later sections. In either case location must be selected with consideration of vent gas exhaust and in the case of indoor installation, the location must have suitable provisions for combustion and ventilation air.
Avoid placing the heater in locations where it can cause damage by water leakage. If this is not possible, provide a suitable drain pan to catch and divert any leakage. The pan must not block natural flow of air to or around the heater.
When a heater or any system component is located below the pool surface a leak can result in large scale water loss or flooding. Waterpik Technologies cannot be responsible for such water loss or flooding. Location of a heater below or above the pool surface affects operation of the heater pressure switch. See sections on water piping and heater
NOTE: See Outdoor Installation section regarding roof overhang.
These clearances are the minimum acceptable. Whenever possible, larger clearances should be provided to assure adequate room for service operations. Note that gas piping may be provided through either side of the unit. See later section on gas piping.
Do not install the heater on carpeting or similar material.
2C-3. Flooring - Typical Installation
The heater must not be installed on combustible flooring without special measures to assure that the floor temperatures will not be excessive.
A special base for combustible floors may be
obtained from Waterpik Technologies. The part number appears in the parts list at the back of this manual (see Section 5)
In the United States, the National Fuel Gas Code allows a heater to be placed on a combustible surface when there is a platform under the heater made of hollow masonry no less than 4 inches (102 millimeters [mm]) thick, covered with sheet metal at least 24 gauge thick and extending beyond the full width and depth of the heater by at least 6 inches (76.2 mm) in all directions. The masonry must be laid with ends unsealed, and joints matched to provide free circulation of air from side to side through the masonry (see Figure 1).
CAUTION
When pool equipment is located below the pool surface, a leak from any component can cause large scale water loss or flooding. Waterpik Technologies cannot be responsible for such water loss or flooding or resulting damage.
2C-2. Installation Clearances
Clearances between the heater and combustible material must be per Table 1.

Notes:
1.Blocks must provide solid base and be braced so they cannot slip out of place.
2.Air openings in blocks must be arranged to provide unrestricted opening through entire width or length of base.
