*These kits include a sidewall venter assembly, vent termination, and barometric damper.

connect the air inlet pipe to a combustion air inlet cap as specified in this section.

Figure 23 – Horizontal DirectAire Installation (Illustration with Sidewall Venter and Sidewall Combustion Air)

Combustion air supplied from outdoors must be free of contaminants (see Combustion and Ventilation Air, page 7).

4. Horizontal DirectAire™ Venting

IMPORTANT: Before installing a venting system, follow all venting clearances and requirements found in the Venting, General Information section, page 10.

The Horizontal DirectAire™ vent system is the same as the Sidewall Venting system, except it pulls combustion air from the outdoors through a sidewall air inlet. Follow all requirements in Sidewall Venting, page 17.

The Horizontal DirectAire™ vent system requires you to install two vent pipes directly to the pool heater; one pipe for flue products and one for combustion air. Install both vent pipes horizontally with a sidewall termination point. For this venting option, you must purchase the DV box accessory from the pool heater manufacturer. The DV box attaches to the air inlet of the pool heater. The pipe for combustion air attaches to the DV box.

Make vent connection directly to the top of the pool heater. No additional draft diverter or barometric damper is required on single unit installations with a dedicated stack and a negative draft maintained between 0.04 to 0.08 inches w.c.

The Horizontal DirectAire™ combustion air supply system has specific vent material and installation requirements. The air inlet pipe connects directly to the pool heater to supply combustion air. The combustion air inlet pipe is a dedicated system with one air inlet pipe per pool heater. You must

Vent Kits

You must order the Horizontal DirectAire™ Vent Kit for sidewall installation. See TABLE–F for kit numbers. Each kit includes a sidewall powered vent cap, proving switch, controls, combustion air inlet cap to supply air to a single pool heater, the transition adapter to attach the field supplied single wall air inlet pipe to the pool heater and installation instructions. Purchase flue pipe and air inlet pipe locally.

The sidewall air inlet cap supplied in the Horizontal DirectAire™ Vent Kit is used to supply combustion air to a single pool heater. Combustion air supply pipes from multiple pool heaters can not be combined into a single air inlet pipe and inlet point.

￿WARNING: Only use the sidewall air inlet cap recommended by the appliance manufacturer. Using another sidewall air inlet cap may result in operational problems and the spillage of flue products. Spillage of flue products can cause personal injury or death due to carbon monoxide poisoning.

Venting of Flue Products

Termination point for the flue products must follow the clearance requirements in Sidewall Vent Termination

Clearances and Location page 11.
