Gas Information

A. Gas Pressure Requirements

Pressure requirements for XLR-CE fireplaces are shown

in Table 11.1 below.
Two taps are provided on the right hand side of the gas

control for a test gauge connection to measure the inlet

and outlet pressures.
The fireplace and its individual shut-off valve must be dis-

connected from the gas supply piping system during any

pressure testing of the system at test pressures in excess

of 60 mbar.
If the fireplace must be isolated from the gas supply pip-

ing system by closing an individual shut-off valve, it must

be of the handle-less type.

Incoming gas line should be piped into the valve compart-

ment and connected to the ISO 7-Rp 1/2 (BSP Rp 1/2)

threaded gas inlet connection on the manual shutoff valve.
Leak test all gas line points and the gas control valve prior

to and after starting the gas appliance.

B. Gas Connection

Note: Have the gas supply line installed in accordance with

local building codes by a qualified installer approved and/or

licensed as required by the locality.

Note: Before the first firing of the appliance, the gas supply

line should be purged of any trapped air.

Note: Consult local building regulations to properly size the gas

supply line leading to the (Rp 1/2 in.) hook-up at the unit.

WARNING

CHECK FOR GAS LEAKS
Explosion Risk
Fire Risk
Asphyxiation Risk
• Check all fittings and connections.
• Do not use open flame.
• After the gas line installation is complete, all

connections must be tightened and checked

for leaks with a commercially-available, non-

corrosive leak check solution. Be sure to rinse

off all leak check solution following testing.

Fittings and connections may have loosened

during shipping and handling.

WARNING

Fire Risk
Explosion Risk
High pressure will damage valve.
• Disconnect gas supply piping BEFORE

pressure testing gas line at test pressures

above 60 mbar.

• Close the manual shutoff valve BEFORE

pressure testing gas line at test pressures

equal to or less than 60 mbar.

Columns highlighted in gray = The gas control valve supplied with this product is approved for a maximum

inlet pressure of 37 mbar. For pressures over 37 mbar, an in line pressure regulator must be installed

upstream from the gas control valve.

C. Access Through the Valve Assembly

Refer to Section 16.C.

There is a vent hole on the regulator to equalize the

pressure on the diaphragm. It also a small amount of

air in the top side of diaphragm to keep the pressure

readings more consisent. This

not for gas leakage.
