Legacy™ Model LRZM Pool/Spa Heater   

|

   Installation and Operation Manual

At least 457 mm access must be available in 

front of the heater for burner removal and access to the 

igniter. 

If the heater is to be installed in a garage, or  

similar structure, all burners and burner ignition 

devices must have a minimum 457 mm clearance 

above the floor. 

This heater must be installed at least 1.52 m 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.

2.5.3  Flooring

The heater must be installed on a 

level 

surface 

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 

Zodiac, is used. See the heater rating plate or the Parts 

List (Section 12) of this manual for the appropriate 

base part number. 

Heaters must never be installed 

directly on carpeting. 

As an alternative to the Zodiac noncombustible 

base plate, the heater may be placed on a combustible 

surface when there is a platform under the heater made 

of hollow masonry no less than 102 mm thick, covered 

with sheet metal at least 24 gauge thick and extend-

ing beyond the full width and depth of the heater by at 

least 153 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 2). If the heater is installed in a 

carpeted alcove, the entire floor of the alcove must be 

covered by a noncombustible panel.

2.5.4  outdoor installation

The Legacy Model LRZ millivolt heater can be 

installed in the low-profile Type A flueless configu

-

ration as received from the factory. Alternately, the 

heater may be installed outdoors using a Type B11 

vent cap. This vent cap is used in high wind installa-

tions. No draft hood is required for this type of outdoor 

installation.

Locate the heater in an 

open, unroofed area

. Do 

not install the heater under a deck. Do not locate the 

heater below or adjacent to any doors, glass openings, 

louvers, grills, etc., which connect in any way with an 

inhabited area of a building, even though the access 

might be through another structure (e.g., a garage 

or utility room). There must be a minimum of 2 m 

horizontally or 2 m vertically between the heater and 

any door, glass opening, or gravity inlet into a build-

ing. See Figure 3.

The top surface of the heater must be at least  

0.91 m above any forced air inlet, or intake ducts 

located within 3.0 m horizontally.

If the heater is installed under an overhang, there 

must be a minimum clearance of 1.5 m above the top 

of the heater and the structure should not overhang the 

heater more than 0.30 m. The area under the overhang 

must be open on three (3) sides. This prevents combus-

tion gases from being diverted into living areas 

through doors, windows, or gravity inlets.

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 un-

restricted opening through entire width or length of base.

3.  Sheet metal must be at least 24 ga. and extend 153 mm 

beyond the heater jacket on all sides.
