Condensate Drain
The PGE/SG package unit is equipped with a 3/4" FPT coupling for condensate line connection. Plumbing must conform to local codes. Use a sealing compound on male pipe threads.
The condensate drain line must be properly trapped and routed to a suitable drain. See Figure 5 for proper drain arrangement. The drain line must pitch to an open drain or pump to prevent clogging of the line. Seal around the drain connection with suitable material to prevent air leakage into the return air system.

Ductwork
Ductwork should be designed and sized according to the methods in Manual Q of the Air Conditioning Contractors of America (ACCA).
A closed return duct system shall be used. This shall not preclude use of economizers or outdoor fresh air intake. It is recommended that supply and return duct connections at the unit be made with flexible joints.
The supply and return air duct systems should be designed for the CFM and static requirements of the job. They should not be sized by matching the dimensions of the duct connections on the unit.
Outdoor ductwork must be insulated and waterproofed.
Equipment is shipped for side ductwork connection. The unit can be converted to bottom ductwork connection by removing the duct covers located over the bottom duct openings and placing these covers over the side duct openings (see Figure 6).
To remove the bottom duct cover over supply opening:
1.Remove screw on cover nearest side opening.
2.Lift end of cover slightly and push to slide back screw/ pin free from duct flange.
When fastening ductwork to side duct flanges on unit, insert screws through duct flanges only; do not insert screws through casing. If using bottom duct work, do not use screws to secure ductwork to bottom duct opening under drain pan side. Using screws to secure bottom duct may damage drain pan.
filters to be installed within the unit. If the filter frame accessory is not used, a filter must be installed in the duct work by the installer. Filters must always be installed ahead of the evaporator coil and must be kept clean or replaced. Dirty filters will reduce the airflow of the unit. Filters should be sized in accordance with Table 2.
Gas Supply and Piping
Refer to the furnace rating plate to make sure the furnace is equipped to burn the gas supplied (natural or propane). See LPG/Propane Units, Tanks, and Piping on page 7 for more information on converting to propane gas.
Gas supply piping should be installed in accordance with local codes and the regulations of the utility. In the absence of local codes, the latest edition of the National Fuel Gas Code ANSI Z223.1 (in the U.S.), or the Natural Gas and Propane Installation Codes CAN/CGA B149.1 & B149.2 (in Canada), should be followed. Piping must be of adequate size to prevent undue pressure drop. Consult the local utility or gas supplier for complete details on special requirements for sizing gas piping.
