SECTION 1.
General Information
1A. Introduction
This manual contains information for the proper
installation and operation of the LX and LT pool/spa
heaters. Certain sections are specific to United States or
Canadian installations, and are labeled United States or
Canada. Procedures in this manual must be followed
exactly. To obtain additional copies of this manual contact
Waterpik Technologies. For address information see back
cover.
1B. Description
The Laars LX and LT have no standing pilot burner.
They exceed the requirements of energy conservation
regulations such as those in California, Hawaii, New York,
Oregon and other states which require that a pool heater
not have a continuous ignition source.
The heaters are designed to operate in conventional
swimming pool and spa equipment arrangements. They
require 120V or 240V, 60 Hz electrical power.
The Laars LX and LT are certified by International
Approval Services, Inc. to comply with latest editions of
applicable U.S./Canadian combined standard for gas-fired
pool heaters. In the United States, the applicable standard
is ANSI Standard Z21.56 for gas-fired pool heaters. In
Canada, it is Standard CSA 4.7. As such, the heater
carries both the AGA and CGA logos.
The heaters have been designed specifically to heat
fresh water swimming pools and spas, and with proper
installation and care, they will provide years of reliable
service. Do not use the heaters to maintain pool or spa
water temperature below 70°F. Do not use them as heating
boilers or general service water heaters or to heat salt
water. For special applications, consult your Waterpik
Technologies dealer.
DANGER
Improper installation or servicing can cause
property damage, injury or death due to fire,
asphyxiation or carbon monoxide poisoning.
1C. Warranty
The LX and LT are sold with a limited factory
warranty. A copy of the warranty is included in a plastic
bag inside the heater and on the back cover of this manual.
The home owner should fill out the warranty registration
card included in the plastic bag and return it to Waterpik
Technologies. The warranty does not cover damage caused
by improper installation, operation, or field modification;
or damage to the heat exchanger caused by corrosive
water. See Section 3D for guidelines on pool water
chemistry.

Installation Instructions
2A. General Requirements
All gas-fired products require correct installation to
assure safe and satisfactory operation. The requirements
for pool heaters include the following:
1.
Appropriate site location and clearances.
2.
Sufficient supply of clean air for combustion and
ventilation.
3.
Proper venting of products of combustion.
4.
Properly sized gas pipe.
5.
Properly sized gas meter.
6.
Adequate water flow.
In the United States, installation must be in
accordance with local codes and the most recent edition of
the National Fuel Gas Code, ANSI Z223.1. The Code can
be obtained from:
National Fire Protection Association
1 Batterymarch Park
Quincy, MA 02269
In Canada, install the heater in accordance with
local codes and the most recent edition of the Installation
Codes for Gas Burning Appliances, CAN 1-B149.1 & .2.
The Canadian Gas Codes are available from:
Canadian Gas Association
55 Scarsdale Road

2A-1.Special Precautions
Liquefied petroleum (LP) gas is heavier than air.
Therefore, a pool heater using LP gas is subject to special
installation rules. Consult local codes and fire protection
authorities about specific installation restrictions.
Fuel gas and its combustion products are known to
cause cancer or harm the reproductive process. Follow
these installation instructions and applicable codes exactly
to avoid this hazard.
2B. Heater Assembly and Preparation
The LX or LT can be installed in a variety of ways,
some of them requiring preparation or assembly in the
field. Water connections are provided on the right side of
the heater but can be changed to the left side by reversal of
the heat exchanger.
