Table 1. Minimum Heater Clearances From Combustible Surfaces
Note: Clearances listed in Table 1 are
manufacturer's tested values. These are
given as minimum values. Where local
and national codes apply, and values
are different than those listed in Table 1,
use the greater value to ensure safe
operation.
conditions such as wind speed and direction, proximity
and height of walls that may block ventilation, and
proximity to public access areas.
2.3.2 Clearances
The heater must be placed to provide clearances
on all sides for maintenance and inspection. There
must also be minimum distances maintained from
combustible surfaces (see Table 1).
At least 24" (457mm) access must be available in
front of the heater for burner removal.
If the heater is to be installed in a garage, or
similar structure, all burners and burner ignition
devices must have a minimum 18" (457mm) clearance
above the floor.
This heater must be installed at least 5 feet
(1.52m) from the inside wall of a pool unless the
heater is separated from the pool by a solid fence, wall
or other permanent solid barrier.
2.3.3 Flooring
The heater must be installed on a floor of
noncombustible construction or on fire-resistant slabs
or arches. Noncombustible flooring is defined as
flooring material and surface finish not capable of
being ignited and burning and with no combustible
materials against the underside. Acceptable materials
are those consisting entirely of a combination of steel,
iron, brick, tile, concrete, slate, glass or plaster.
Do not
install the heater directly on a combustible wood or
carpet floor without placing a noncombustible platform
between the floor and the heater.
The heater can be installed on a combustible
floor if a noncombustible base assembly, available
from Jandy, is used. See the Parts List (Section 10) of
this manual for the appropriate base part number.
Heaters must never be installed directly on
carpeting.
As an alternative to the Jandy noncombustible
base plate, 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 3). If the heater is installed in a carpeted
alcove, the entire floor of the alcove must be covered
by a noncombustible panel.
Figure 3. Non-Combustible Platform.
Notes:
1. Blocks must provide a solid base and be braced so they
cannot slip out of place.
2. Air openings in blocks must be arranged to provide
unrestricted openings through entire width or length of
base.
3. Sheet metal must be at least 24 ga. and extend 6"
beyond the heater jacket on all sides.
