Gas Supply - Empire Comfort Systems OP36FP32MN-3 Installation Instructions And Owner's Manual

The fireplace installation must conform with local codes, or in the
absence of local codes with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54; International Fuel Gas Code, Natural Gas and
Propane Installation Code, CSA B149.1; or Propane Storage and
Handling Code, B149.2, as applicable.
Check all local codes for requirements, especially for the size and
type of gas supply line required.

NOTICE: Check to confirm whether your local codes allow
copper tubing or galvanized.
NOTICE: Because some municipalities have additional local
codes, consult your local authority and installation code.
Installing a New Gas Shut-Off Valve
Each appliance must have its own manual gas shut-off valve
located in the vicinity of the unit. Where none exists, or where
its size or location is not adequate, contact your local authorized
installer for replacement or relocation.
Test for leaks. Turn fireplace off. Compounds used on threaded
joints of gas piping shall be resistant to the action of liquefied
petroleum gases. The installer must check all gas connections
for leaks. Perform all leak tests with a leak test solution or soap
solution. Rinse off all solution once testing is complete. Perform a
pressure test on all unexposed connections.
Never use an exposed flame to check for leaks. Never
pressure test with appliance connected; control valve will
sustain damage. Disconnect the appliance from piping at the
control valve inlet and cap the pipe before pressure testing.
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 line near the gas inlet. The drip
line consists of a vertical length of capped pipe installed before
the gas inlet to collect condensation and foreign particles. See
Figure 5.
