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.

A. Gas Pressure Requirements

Pressure requirements for SOHO-CE ﬁ replaces 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 ﬁ replace 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 ﬁ replace 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 qualiﬁ ed installer approved and/or

licensed as required by the locality.

Note: Before the ﬁ rst ﬁ ring 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 ﬁ ttings and connections.

• Do not use open ﬂ ame.

• 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.
