ULTRATEMP ETI™ Hybrid Heater Installation and User’s Guide
3
Equipment Pad
For proper drainage of condensation and rain water, place the heater on a flat slightly pitched surface, such as a
concrete or fabricated slab (pad).
If possible, place the pad at the same level or slightly higher than the filter system equipment pad.
The equipment pad should also be in an area where leaves or other combustible debris will not collect on or
around the heater.
Note:
Be sure that the pad is pitched not more than 1/4 in. per foot in any direction as needed for runoff.
Note:
The equipment pad should be no less than 4 in. (100 mm) thick.
Recommended Clearances
All criteria given in the following sections reflect
minimum clearances. However, each installation must
also be evaluated, taking into account the prevailing
local conditions such as proximity and height of walls,
and proximity to public access areas.
The UltraTemp ETi™ Hybrid Heater must be placed
to provide clearances on all sides for maintenance
and inspection. Refer to
Figure 2
for a visual
representation of the proper clearances.
1. At least 30 inches [610 mm] of clearance is
required on both the plumbing and control panel
side of the heater. This will provide necessary
room for servicing.
2. At least 12 inches [305 mm] of clearance must
be available on all the other sides of the heater to
allow for proper air flow.
3. If the heater is to be installed under a cover or
under a vertical overhang, the unit must have a
minimum of five (5) feet [1.5 m] clearance from
the top of the heater.
4. Install a minimum of five (5) feet [1.52 m] from the
inside wall of the pool or spa unless the heater is
separated from the pool or spa by a five (5) foot
[1.52 m] high solid fence or other permanent barrier.
Canadian installations require a minimum of three
(3) meters [9.84 ft] from pool water.
5. Install heater a minimum of 12 in. [305 mm] from the
wall of the house.
6. For minimum exhaust vent clearances, see
Figure 3
on next page.
Note:
In Canada, the heater must be installed with
the top of the vent at least 10 ft. (3 m) below, or to
either side of, any opening into a building.
If installing the heater next to or near an air
conditioning unit, heater or another gas pool
heater, allow a minimum of 36 in. (91.4 cm) between the unit and
the heater.
