VI. TRAP CONDENSATE DRAIN

See Fig. 2, 3, and 9 for drain location. Condensate drain is open to the atmosphere and must be trapped. Install a trapped drain at the drain location. One 1-in. NPT coupling is pro- vided inside unit evaporator section for condensate drain con- nection. A trap at least 4-in. deep must be used. Trap must be installed to prevent freeze-up.

(Typical Roof Curb or

Slab Mount Shown)

Condensate pans are sloped so that water will completely drain from the condensate pan to comply with indoor air quality guidelines.

VII. GAS PIPING

Unit is equipped for use with natural gas. Installation must conform with local building codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1.

Install manual gas shutoff valve with a 1¤8-in. NPT pressure tap for test gage connection at unit. Field gas piping must include sediment trap and union. See Fig. 10.

WARNING: Do not pressure test gas supply while connected to unit. Always disconnect union before servicing.

Natural gas pressure at unit gas connection must not be less than 5 in. wg or greater than 13.5 in. wg.

Size gas-supply piping for 0.5-in. wg maximum pressure drop. Do not use supply pipe smaller than unit gas connection.
