• The gas supply pipe should enter the appliance case through the opening

at the left side. The supply pipe should be connected to the appliance

gas inlet pipe situated at the left side of the control valve. Supply line

connection to the inlet pipe is 3/8 inch NPT ( female).

If the circulating fan is to be installed, be aware that the supply pipe

run inside the case should be at the same height as the appliance

inlet pipe in order to clear the fan. If intending to ﬁ t 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 sufﬁ cient 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 propane 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 to allow the appliance to be disconnected for servicing.

• A plugged 1/8 inch 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.

• 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 the Speciﬁ cations 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 ﬂ ame to check for leaks.

Correct any leak detected immediately.

• The pressure test tapping locations are shown on the right. A

built-in non-adjustable regulator controls the burner manifold

pressure. The correct pressure range is shown in the table in

Speciﬁ cations 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.
