9 Gas Information

A. Gas Pressure Requirements

Pressure requirements for SOHO-CE fireplaces are shown in Table 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. See Section 10: Maintaining and Servicing the Appliance.

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.

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.

Table 1

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.

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.

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.
