If a floor drain is not available, a condensate pump can be used to remove the condensate to
drain. The maximum condensate flow rate is 40 GPH. The condensate drain trap, associated
fittings and drain line must be removable for routine maintenance.
Use PVC, stainless steel, aluminum or polypropylene for condensate drain
piping (Figure 2-6). DO NOT use carbon or copper components.

2.8 GAS SUPPLY PIPING
The AERCO Benchmark Gas Components and Supply Design Guide, GF-2030 must be
consulted prior to designing or installing any gas supply piping.
NEVER USE MATCHES, CANDLES, FLAMES OR OTHER
SOURCES OF IGNITION TO CHECK FOR GAS LEAKS
.
Many soaps used for gas pipe leak testing are corrosive to metals.
Therefore, piping must be rinsed thoroughly with clean water after
leak checks have been completed.
