Natural Gas Hook-Up

The gas appliance is designed to operate with natural gas at an inlet pressure of 7 inches water column.
The piping up to the appliance is the responsibility of the installer. A flexible metal connector is included
to simplify the installation of the appliance. Ensure that the connector does not pass through a wall, floor,
ceiling or partition, and is protected from damage. Do not use a hose to connect the appliance. The gas
supply pipe must be sufficiently sized to supply the BTU/h specified on the rating plate, based on the
length of the piping run.
Purge the gas supply line of any trapped air prior to the first firing of the appliance.
