1.
The appliance is supplied for supply gas connection at the left hand
side of the case. There is also a gas line access at he rear of the firebox
for insert applications, see fig 7.The zero clearance kit does not have
access at the rear. Supply line connection to the flexible adapter is

/
"NPT male thread.

Alternatively, the appliance inlet pipe may be removed and the supply
line routed directly to the control unit. An isolating valve could be fitted
within the appliance case.
2.
Use only new black iron or steel pipes or copper tubing if
acceptable - check local codes. Note that in USA copper tubing must be
internally tinned for protection against sulfur compounds.
3.
Ensure there is a pipe union (or flare fitting where permissible)
ahead of the burner module for future servicing. Unions in gas lines
should be of ground joint type.
4.
The gas supply line must be sized and installed to provide a supply
of gas sufficient to meet the maximum demand of the appliance without
undue loss of pressure.
5.
Sealant used must be resistant to the action of all gas constituents
including LP gas. Sealant should be applied lightly to male threads to
ensure excess sealant does not enter gas lines.
6.
The supply line should include a manual shut-off valve to allow the appliance to be disconnected for servicing.
A plugged 1/8"NPT tapping must be installed in the line. The tapping must be accessible for test gauge connection and be
immediately upstream of the gas supply connection to the appliance.
7.
Pressure test the supply line for leaks.
• 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 ½psig (3.5kPa).
• 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 ½psig (3.5kPa).
• Failure to either disconnect or isolate the appliance during pressure testing may result in regulator or valve damage.
Consult your dealer in this case.
8.
The minimum supply pressure is given in section 3 of this manual.
9.
All piping and connections must be tested for leaks after installation or servicing. All leaks must be corrected
immediately.
When testing for leaks:
• Make sure that the appliance is turned off.
• Open the manual shut-off valve.
• Test for leaks by applying a liquid detergent or soap solution to all joints. Bubbles forming indicate a gas leak.
Never use an open flame to check for leaks.
Correct any leak detected immediately.
10. The pressure test tapping locations are shown in figure 8 . A built-in regulator controls the burner manifold pressure. The
correct pressure range is shown in the table in section 3 of this manual. The pressure check should be made with the burner
alight and the input set to its highest setting. See lighting instruction section for full operating details.
