Gas Supply - Empire Comfort Systems VFP20IN30L10-1 Installation Instructions And Owner's Manual

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 Figures 8 and 9. Consult
the current National Fuel Gas Code, ANSI Z223.1 CAN/CGA-B149
(.1 or .2) installation code.

NOTICE: Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
NOTICE: Since some municipalities have additional local codes, it
is always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANS Z21.45 A ssembled Flexible A ppliance 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.

Installing the Main Gas Shut-Off
Each appliance should have its own manual gas shut-off.
A manual main gas shut-off 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.
L.P.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
3/8"
capped or plugged for pressure test. Never pressure test with
9.5mm
appliance connected; control valve will sustain damage!
1/2"
NOTICE: The millivolt gas controls are equipped with a captured
12.7mm
screw type pressure test point, therefore it is not necessary to
1/2"
provide a 1/8" test point up stream of the control.
12.7mm
When using copper or flex connector use only approved fittings.
3/4"
The appliance and it's individual shut off valve must be disconnected
1.9 mm
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
The appliance 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).
Attention! If one of the procedures results in pressures in excess of
1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will result
in a hazardous condition.
