Gas Line Installation
After leveling, position the insert in the fireplace, holding it about
six inches out from its final location.
Caution: Specific Hearth Requirements apply (see Clearances
and Specifications). The Designer™ gas insert must be con-
nected to the gas line in accordance with local codes and / or
the National Fuel Gas Code--- Z.1-latest edition, also known
as NFPA 54 (In Canada, the current CAN/CSA B149.1 installa-
tion code). Included in the manual package is a 8" gas nipple.
Locate the threaded gas inlet on the lower left of the insert.
Thread the 8" gas nipple into the inlet with a teflon sealer or
equiv. Attach the gas supply line to this hard pipe. The hard
pipe can receive a /8" inch female iron pipe coupling, or a shut
off valve. After connecting the gas line, all joints in the line and
connections at the valve should be checked for leaks.

A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS
APPLIANCES IS IMPROPER GAS PRESSURE!
The most important item to check during the initial
installation and the first thing to check when operating
problems occur is gas pressure! This appliance will
not function properly unless the required gas pressure
is supplied. See the table on this page for gas pressure
requirements.
Two pressure taps are provided on the insert's valve to check gas
pressures. The taps are located to the right of the on/off/pilot knob
(see Figure 15). The bottom tap is the inlet (supply) pressure side.
To check inlet pressure (with the insert burning), insert a small
phillips screw driver into the tap and turn a half turn counter-
clockwise. Cover the tap with the line from a manometer and check
the pressure. Close tap gently but securely after completing the
check. The manifold (outlet) tap is above the inlet tap. To check
manifold pressure (with the insert burning at the high burn setting)
insert a small phillips screw driver into the tap and turn a half turn
counter-clockwise. Cover the tap with the line from the manometer
and check the pressure. Again close the tap gently but securely
after completing the check. Check the taps for gas leaks with a
gas leak test solution (retighten if necessary).
If the pressure is not sufficient, make sure the gas supply line
is large enough, the supply regulator is properly adjusted, and
the total gas load for the residence does not exceed the amount
supplied.
The appliance and its individual shut off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/ psig.
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/ psig. Check with your gas
supplier or plumber.

The proper gas line diameter must be selected to run from the
supply regulator to the insert. Refer to the following table for
proper gas pipe diameters.
