Connect the Gas Line
All codes require a shutoff valve mounted in the supply line. Figure 31 illustrates two methods for connecting the gas
supply. The flex-line method is acceptable in the U.S., however, Canadian requirements vary depending on locality.
Installation must be in compliance with local codes.
NOTE: A sediment trap is recommended in the gas piping within the home to prevent moisture and debris in the line
from damaging the valve.
NOTE: Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds
are used in propane applications). Seal around the gas line to prevent cold air leakage. Gas line holes and other
openings can be caulked or stuffed with unfaced fiberglass insulation.

These fireplaces are equipped with a gas flex line for use (where permitted) in connecting the unit to the gas line. A
gas flex line is provided to aid in attaching the direct-vent fireplace to the gas supply. The gas flex line can only be
used where local codes permit. The flex line is rated for both natural and propane gas. A manual shut off valve is
also provided with the flex line.
The gas control valve is located in the lower control compartment (Figure 1, Page 9).
Access the Control Compartment
See Page 53 for instructions on Accessing the Control Compartment.
Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds are
used in propane applications). Optionally, seal around the gas line to prevent cold air leakage. Gas line holes and
other openings can be caulked or stuffed with unfaced fiberglass insulation.
All codes require a shutoff valve mounted in the supply line. The orientation of the shutoff valve should face the
front. Figure 31 illustrates two methods for connecting the gas supply. A sediment trap is recommended to prevent
moisture and debris in the gas line from damaging the valve.
