GAS SUPPLY (CONT’D)
Installing a New Main Gas Supply Shut-off Valve (Check
Local Code)
Each appliance must have its own manual gas shut-off valve
located in the vicinity of the fireplace. 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 must 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 fireplace connected; control valve will sustain damage.
Disconnect the fireplace from piping at the control valve inlet and
cap the pipe before pressure testing.
NOTICE
: The millivolt gas controls are equipped with a captured
screw type pressure test point, therefore it is not necessary to
provide a 1/8 inch test point up stream of the control.
Use only approved fittings with copper or flex connectors.
Disconnect the fireplace and its individual shut-off valve from the
supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5 kPa).
Close the fireplace manual shut off valve to isolate it from the
gas supply piping system during any pressure testing of the gas
supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
WARNING
If one of the test procedures results in pressures in excess
of 1/2 psig (14
inches
w.c.) (3.5 kPa) on the fireplace gas
valve, it will result in a hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5
inches
w.c. (.871 kPa) at the valve
outlet with the inlet pressure to the valve from a minimum of 4.5
inches
w.c. (1.120 kPa) for the purpose of input adjustment to a
maximum of 14.0
inches
w.c. (3.484 kPa). Propane gas models
will have a manifold pressure of approximately 10.0
inches
w.c.
(2.49 kPa) at the valve outlet with the inlet pressure to the valve
from a minimum of 10.8 inches w.c. (2.68 kPa) for the purpose of
input adjustment to a maximum of 14.0
inches
w.c. (3.484 kPa).
