START- -UP, ADJUSTMENT, AND SAFETY 1. Remove upper and middle collector box drain plugs oppos- ite of the condensate trap. See Fig. 59. CHECK 2. Connect field-supplied 5/8- -in. (16 mm) ID tube with at- General tached funnel to upper collector box drain connection. See Fig. - Page 61 (Furnace is shipped with No. 44 orifices. In this example, all main NOTICE burner orifices are the correct size and do not need to be changed to obtain proper input rate.) Manifold pressure: 3.4- -in. w.c. (847 Pa). The NATURAL GAS manifold pressure adjustments in Table 21 compensate for BOTH altitude AND gas heating value.
