different, DO NOT INSTALL the heater. Contact your dealer for the correct model.

SEDIMENT TRAP
Use new black iron or steel pipe only. Internally tinned copper tubing can be used in some areas
when permitted by local codes. Only use pipe of 1/2" or greater diameter to allow full gas
volume to heater. Excessive pressure loss will occur if the pipe is too small.
A manual shutoff valve, union and plugged 1/8" NPT pressure tapping point must be installed
upstream of the heater (FIGURE 4).
A sediment trap must be installed upstream of the heater to prevent moisture and contaminants
from passing through the pipe to the heater controls and burners. Failure to do so could
prevent the heater from operating reliably (FIGURE 4).
