A. Gas Pressure Requirements
Pressure requirements for SOHO-N-AU 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 15
: 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
AS5601-2004 - Gas Installations by authorised personnel.
Note:
Before the fi rst fi ring of the appliance, the gas supply
line should be purged of any trapped air.
Note:
Consult AS5601 table 3.1 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.
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.
