Gas sUpplY
If the fireplace where you are installing the insert has no gas line
access hole, drill an access hole of 1.5 inch (37.5 mm) or less
through the lower sides or bottom of the firebox. After the running
the gas line, use non-combustible insulation to block the opening
around the pipe.
The gas pipeline can be brought in through the right or left side of
the appliance. The insert has a Flexline with shutoff valve located
on the right side when facing the unit.
see Figure 3.
Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/
CGA-B149 (.1 or .2) installation code.
NOTICE
: Once the gas access hole is drilled, the fireplace
cannot be converted back to burning a solid-fuel.

NOTICE
:
Never use plastic pipe for gas line. Check local codes
before using copper tubing or galvanized.
NOTICE
:
Some municipalities have additional codes. Consult
your local authority and installation code.
Use the following gas connectors:
— ANSI Z21.24 Appliance Connectors of Corrugated Metal
Tubing and Fittings.
— ANSI Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The Commonwealth of Massachusetts
requires that a flexible appliance connector cannot exceed three
feet in length.

Install a gas valve and ground joint union in the gas line upstream
of the gas control to aid in servicing. The National Fuel Gas
Code requires installing a drip leg near the gas inlet. The drip leg
consists of a vertical length of capped pipe installed before the gas
inlet to collect condensation and foreign particles.
