A qualified gas appliance installer must connect the fireplace to the gas supply.
Consult all local codes.
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).
