2B. Heater Assembly and Preparation
The Hi-E
can be installed in a variety of ways,
2
some of them requiring preparation or assembly in
the fi eld. In all cases, condensate tubing and fi ttings,
which are provided with the heater, must be connected
and routed. Water connections are provided on the
right side of the heater but can be changed to the left
side by reversal of the water headers.
It is best to handle these preparations before the
heater is in its fi nal location. Instructions are provided
in subsequent sections of this document.
Installation at High Elevation
The Hi-E
has a venturi-type combustion system
2
which does not require modifi cation for operation at
high elevation. In this type of system, air and fuel gas
density changes are automatically compensated for,
assuring proper air/fuel mixture. Heating capacity is
reduced about 3 percent per 1000 feet (305 meters)
above sea level. In general, effi ciency at high elevation
is equal to or better than at sea level.
2C. Heater Location
The Hi-E
may be installed indoors or outdoors
2
as outlined in later sections. When installed indoors,
combustion air will often be piped to the heater and
this requirement may affect the choice of location (see
later section on air for combustion and ventilation).
Both indoor and outdoor installations require provision
of means for disposal of combustion condensate per
section 2H.
Install the heater at least 5 feet (1.52 meters)
from the inside wall of the pool or spa unless the
heater is separated from the pool or spa by a fi ve-foot
(1.52 meter) high solid fence, wall or other permanent
barrier.
When pool equipment is located below the pool
surface, a leak from any component can cause large
scale water loss or fl ooding. Jandy Pool Products Inc.
cannot be responsible for such water loss or fl ooding
or resulting damage. Location of the heater below
or above the pool deck affects operation of its water
pressure switch. See sections on water piping and
heater start-up for more information about this.
WARNING
When pool equipment is located below the pool sur-
face, a leak from any component can cause large
scale water loss or fl ooding. Jandy Pool Products,
Inc. cannot be responsible for such water loss or
fl ooding or resulting damage.
Locate the heater in an area where water
leakage will not result in damage to the area around
the appliance or to a structure. If forced to locate
the heater where water leakage may cause damage,
provide a suitable pan with drain under the heater. This
pan must not restrict air fl ow or heater functions.
In selection of a location, disposal of combustion
condensate must also be considered. The heater can
produce three gallons of condensate water per hour
under some operating conditions. Means to drain this
condensate must be available or special provisions,
such as a condensate pump must be provided. See later
section on condensate disposal.
2D. Installation Clearances
Clearances between the heater and combustible
material must be per Table 1.

* For Canada 24 inches (610 mm) clearance
Table 1. Installation Clearance Requirements.
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 must be provided
through the left side of the unit and that the
combustion air duct, when provided, also enters
through the left side. See later section on combustion
air, and also the section on water piping.
Do not install the heater on carpeting or similar
material.
2E. Outdoor Installation
Locate the heater in an open, unroofed area
and maintain the clearances shown in Table 1. Do
not locate the heater below or adjacent to any doors,
windows, louvers or grates, etc., which connect in any
way with an inhabited area of a building, even through
another building such as a garage or utility room (see
Figure 1). Do not locate the heater below an outdoor
deck, unless treated as an indoor installation with
adequate clearances and proper venting to a location
away from the deck.
