After removing all shipping brackets, level the fan using the adjustment screws. On all 4 corners the dimension from cross rail to fan sled should be as shown in Fig. 52.

Step 16 — Connect Gas Piping — Unit is equipped for use with natural gas only. Installation must con- form with local building codes, or in the absence of local codes, with the National Fuel Gas Code (NFGC), ANSI Z223.1.

A 1/8-in. NPT tapping plug, accessible for test gage connec- tion, must be field installed immediately upstream of gas sup- ply connection to unit, but after manual gas valve. See Fig. 53. Natural gas pressure at unit gas connection must not be less than 5 in. wg or greater than 13 in. wg.

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

CAUTION

NOTE: All dimensions are in inches.

Disconnect gas piping from unit when leak testing at pres- sures greater than 0.5 psig. Pressures greater than 0.5 psig will cause gas valve damage resulting in a hazardous con- dition. If gas valve is subjected to pressure greater than 0.5 psig, it must be replaced.

Step 17 — Configure Optional Staged Gas or Modulating Gas Control — The 48P Series large rooftop units may be ordered with an optional factory-installed staged gas or modulating gas control system that monitors heating operation of the rooftop.

Refer to the Unit Controls and Troubleshooting book for in- formation on configuring staged gas or modulating gas control.
