Figure 1. Outdoor heater location.

If the heater is installed close to a structure, protect it from rain water runoff by means of gutters, roof water diverters or similar measures. Do not locate the heater close to irrigation sprinklers. Water from sprinklers may damage controls and electronic components.

Because the Hi-E2is very efficient, combustion system exhaust gases are moist. Do not locate the heater such that this exhaust will impinge on structures or vegetation which may be damaged by combustion condensate.

WARNING

In United States

Do not install the heater with the vent within 4 feet (1.22 m) of any opening into a building.

In Canada

Do not install the heater with the vent within 10 feet (3.05 m) of any opening into a building.

located in. A two-pipe system (sometimes referred to as “direct vent” or “sealed combustion”) has a vent pipe plus a pipe bringing air directly to the heater's combustion system.

Section 2G-2 specifies requirements for provision of combustion and ventilation air for one-pipe installations. Section 2G-3 covers two-pipe installation.

An important consideration in selecting one or two pipe installation is the quality of the combustion air. Indoor air is sometimes contaminated with various household or pool sanitation chemicals which can cause corrosion in the heater combustion system. Unless the indoor air is known to be free of these materials, two pipe installation is strongly recommended.

2G-1. Preparation of Heater For Indoor Installation

If the Hi-E2is to be installed indoors, its exhaust discharge grille must be converted to an exhaust pipe configuration. The necessary vent collar, gasket and screws are shipped packaged within the heater. The

2F. Outdoor Shelter Installation (Canada)

An outdoor shelter is an unoccupied enclosure which does not communicate directly with occupied areas. The Hi-E2may be installed in such a shelter only when the installation is in accordance with local codes and the most recent edition of Standard CAN/ CGA B-149. These codes and standards and Teledyne Laars require that the heater be properly vented as outlined in this manual. Other requirements also apply, such as provision of ample uncontaminated air for combustion and ventilation.

2G. Indoor Installation
The Hi-E2can be located indoors when provided
with “one-pipe” or “two-pipe” systems for combustion
air and combustion product venting. A one-pipe
installation has only a vent pipe, and air for
combustion must be provided to the room the heater is	Figure 3. Vent collar assembly for indoor installation.
