Raypak 009839 Indoor Stack Kit (Drafthood), 7" Vent, for 266/266A, 266L/267A, 268A Pool Heaters

This is the indoor drafthood for Raypak gas pool and spa heaters; Raypak's manuals call it the indoor stack kit. It connects the heater to a vent pipe so the flue gases are carried out of the building. These heaters come with the outdoor stackless top only and Raypak lists the indoor stack as optional equipment, so an indoor installation needs this kit ordered separately.

Also fits:

• Raypak 268A Professional Series heaters (some Raypak documents write the model as 268)
• Raypak 267A digital Low NOx heaters (Raypak dates the residential 267A to 2004 through 2023)
• Raypak 266A millivolt heaters (built 2004 to 2020)

Other sizes:

• Other cabinet sizes take a different kit: 009838 for the 206A and 207A, 009840 for the 336A and 337A, 009841 for the 406A, 407A and 408A
• Not for the earlier RP2100 heaters (R265A and R265B, built 1998 to 2004): Raypak lists indoor stack kit 006697 for those

Details:

• In the box, per Raypak: 1 unpainted drafthood, 1 adapter plate, 3 mounting brackets (clips), 3 screws and the instructions
• Vent outlet (flue) diameter: 7 in. (178 mm)
• Overall height with the indoor drafthood in Raypak's dimension tables: 62 in. (1575 mm) on the 266A and 268A, 56 in. (1422 mm) on the 267A

• Raypak's contents list for the kit has no vent pipe or vent cap

Good to know: Raypak calls for a Category I vent on the drafthood, recommends Type B double-wall pipe the same size as the drafthood outlet, and requires at least 5 ft of vertical vent above the outlet. An indoor heater also needs combustion and ventilation air openings; the heater manual gives the minimum sizes. Where the vent has to run through a side wall, Raypak offers the D-2 Power Vent for electronic-ignition heaters instead of this drafthood (kit 009832 or 010744 for this size). Venting a gas heater is work for a qualified installer, following the heater manual and local code.
