Empire Comfort Systems DVCTL60CFP95N Instructions D'installation page 19

The gas pipeline can be brought in through the right side of the
fireplace. The fireplace has a Flexline with shut-off valve located
on the right side when facing the fireplace. See Figures 22 and 23.
Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/
CGA-B149 (.1 or .2) installation code.

CAUTION: Never use plastic pipe. Check to confirm whether your
local codes allow copper or galvanized tubing.
NOTICE: Some municipalities have additional local codes.Consult
your local authority and installation code.
The use of the following gas connectors is recommended:
— ANSI Z21.24 Fireplace Connectors of Corrugated Metal Tubing
and Fittings.
— ANSI Z21.45 Assembled Flexible Fireplace 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 fireplace connector cannot exceed three feet in length.
Installing The Main Gas Shut-Off
Each fireplace should have its own manual gas shut-off.
A manual main gas shut-off should be located in the vicinity of the
fireplace and can be easily accessed. Where none exists, or where its
size or location is not adequate, contact your local authorized installer
for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant to
the action of liquefied petroleum gases. The gas lines must be checked
for leaks by the installer. Testing for leaks on all exposed connections
should be done with leak test solution or a soap solution. After testing is
complete, all solution should be cleaned off. On unexposed connections,
a pressure test should be made.
Never use an exposed flame to check for leaks. Fireplace
must be disconnected from piping at inlet of control valve and
pipe capped or plugged for pressure test. Never pressure test
with fireplace connected; control valve will sustain damage.

WARNING
NOTICE: The gas controls are equipped with a captured screw-type
pressure test point. It is not necessary to provide a 1/8-inch test
point up stream of the control.
When using copper or flex connector use only approved fittings.
The fireplace and its individual shut-off valve must be disconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
The fireplace must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5kPa).
3/8
If one of the procedures results in pressures in excess of
1/2
1/2 psig (14 inches w.c.) (3.5 kPa) on the fireplace gas valve,
it will result in a hazardous condition.

A gas valve and ground joint union should be installed in the gas line
upstream of the gas control to aid in servicing. The National Fuel
Gas Code requires that a drip leg be installed near the gas inlet.
See Figure 24. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.
