SECTION 2.
Installation
2.1 Boiler Placement
The pool heating boiler must be placed to provide specific clearances on all sides for maintenance and inspections. There must also be minimum distances maintained from combustible surfaces. These clearances also apply to noncombustible materials because the pool heating boiler requires air circulation for proper operation.
The pool heating boiler should be mounted on a level surface. An integral base for an installation on combustible flooring is provided as standard equipment on outdoor models. For indoor models, special base rails part number 10539000 must be used for combustible flooring.
Do not install a pool heating boiler on carpeting. Under the national Fuel Gas Code, ANSI
Z223.1, it is permissible to place the boiler on floors other than noncombustible when the installation complies with the American Insurance Code. Figures 2, 3, 4 and 5 show common installation on combustible flooring.
2.2 Installation of Indoor Boilers
Locate the pool heating boiler to provide
adequate clearance for inspection and service on all sides. See Table 1. For alcove installation, see Figure 6.
Install indoor heaters on a waterproof floor with an adequate floor drain and a 6" (152mm) minimum curb on all four sides to protect the building if heater repairs are required. The manufacturer will not be held liable for any water damage in connection with this boiler.
2.2.1 Combustion Air Supply
The heater location must provide sufficient air supply for proper combustion and ventilation of the surrounding area as outlined in the latest edition of ANSI standard Z223.1, and any local codes that may be applicable. Inadequate combustion air supply may result in incomplete combustion, sooting of the heat exchanger, and unsafe operation of the boiler.
a. Conventional Ventilation
In the United States, the most common of these requirements specify that boiler rooms should be provided with two permanent air supply openings communicating directly through the wall to outside air one within 12 inches (305mm) of the ceiling, and the other within
12 inches (305mm) of the floor. Each opening should have a minimum free area of one square inch
(6.5 sq. cm) per 4,000 BTU/hr input of the total input rating of all appliances in the enclosed area. See Table 2 for recommended air supply for each model. An

*Water connection and pump side clearances of 24" (610mm) and front clearances of 48" (1219mm) will allow easier service access.
**Using type B vent (refer to Manufacturer's Instructions).
