•
It's preferable to rough-in the gas line at this point before proceeding with the firebox installation.
•
The appliance is supplied for supply gas connection at the rear left corner of the case. Supply line connection to
the inlet pipe of the appliance is 3/8"NPT (female).
Alternatively, the appliance inlet pipe may be removed and the supply line routed directly to the control unit
having a 3/8" NPT female thread. Take care not to torque the valve or damage the wire connectors on the valve.
An isolating valve could be fitted within the appliance case. If the circulating fan is to be installed, be aware that
the supply pipe should follow the route of the original appliance inlet pipe in order to clear the fan. If intending to
fit an internal isolating valve, check that it will be clear of the fan.
•
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.
•
Unions in gas lines should be of ground joint type.
•
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.
•
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.
•
The supply line should include a manual shut-off valve and union to allow the appliance to be disconnected for
servicing.
•
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 1/2 psig (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 1/2 psig (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.
•
The minimum supply pressure is given in Specifications
section of this manual.
•
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.
•
The pressure test tapping locations are shown in figure above. A built-in non-adjustable regulator controls the
burner manifold pressure. The correct pressure range is shown in the table in the Specifications section of
this manual. The pressure check should be made with the burner alight and at its highest setting. See Lighting
Instructions section for full operating details.
