Raypak 009832 D-2 Indoor Power Vent Kit, 240V Factory Wired, Convertible to 120V, for 206A, 207A, 266A, 267A, 268 Pool Heaters (IID Only)

In the box, per Raypak: D-2 Power Vent, collar adapter, 7/8 in. plastic grommet, adjustable 90 degree elbow with screen (the side-wall termination) and 4 in. flue adapter.

• Blower motor: 120/240 V, 60 Hz, 1.95/1.0 A, 3200 RPM, in a plenum with a draft-proving switch and motor relay.
• The blower can be rewired for 120 V. The same kit wired for 120 V at the factory is 010744.
• The 336A, 337A, 406A, 407A and 408A take the larger kit: 009833 wired for 240 V or 010745 wired for 120 V.
• Raypak model 266 is listed together with the 266A in an earlier revision of the 206A-406A manual. Raypak does not list the D-2 for millivolt heaters.
• Vent connection: 4 in. collar. Category III vent pipe and a 4 in. gasket-to-gasket flue adapter are field-supplied, not in the kit.
• Maximum vent run: 100 equivalent ft including the termination; each 90 degree elbow counts as 10 ft, each 45 degree elbow as 5 ft, and no more than four 90 degree elbows.
• Needs at least 24 in. of clearance above the unit.
• Mounting brackets are relocated when the unit goes on a 206A or 207A; that step is skipped on the 266A, 267A and 268A.
• A wire harness connects the unit to the heater controls; the draft-proving switch has to close before the main gas valve can open.
• Raypak states the D-2 is tested and certified to ANSI Z21.56.

For a through-the-wall installation Raypak requires the screened elbow supplied in the kit to be the vent termination. Category I vent material such as B-vent must not be used with the D-2; it runs at positive vent pressure and needs Category III pipe. Raypak does not support common venting of positive-pressure vent systems.

Installation involves gas venting and line-voltage wiring and must be done by a qualified installer following Raypak's D-2 manual (P/N 241243) and local code.
