Gas Connection - USSC VFZC32L Owner's Operation And Installation Manual

GAS CONNECTION

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 8).
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 8).

CHECK GAS TYPE: The gas supply must be the same as stated on heater's rating plate. If the
gas supply is different, DO NOT INSTALL the heater. Contact your dealer for the correct model.
Connecting directly to an unregulated propane/LPG tank can
cause an explosion.
