GAS SUPPLY
(continued)
Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Valve
Each appliance should have its own manual gas valve.
In the state of Massachusetts the gas valve must be a T handle
type.
A manual main gas valve should be 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 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. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must be
disconnected from piping at inlet of control valve, and pipe capped
or plugged for pressure test. Never pressure test with appliance
connected; control valve will sustain damage!
PLACEMENT OF GLOWING EMBERS AND LAVA ROCKS
Placement of the glowing embers (rock wool) is very individual,
and light coverage will provide your best effects. We recommend
separation of the rock wool by hand, and make your coverage as
light and fluffy as possible.
Place just enough embers on the burner to obtain the glow and a
gold, yellow flame. (Figure 12)
Do not place embers (rock wool) over large ports in rear portion of
burner.
Rock wool should not be placed in the area of the pilot assembly.
Spread lava rock on fireplace floor in front of and on either side of
the burner assembly. The lava rock is for decorative effect and is
not required for appliance operation.
WARNING: DO NOT PLACE LAVA ROCK ON BURNER,
LOGS OR EMBERS. THE LAVA ROCK SHOULD ONLY BE
PLACED ON THE FIREPLACE FLOOR.
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. 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.
The use of the following gas connectors is recommended:
– ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
– ANS 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 state of Massachusetts requires that a
flexible appliance connector cannot exceed three feet in length.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3.175mm)
N.P.T. plugged tapping, accessible for test gauge connection,
must be placed immediately upstream of the gas supply
connection to the appliance.
2. The appliance and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig
(3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will
result in a hazardous condition.
