Gas Supply

Gas Supply

Only persons licensed to work with gas piping may make the necessary gas connection to this appliance. You are now ready to hook up the gas supply. Be sure that gas plumbing instructions and all provincial and local codes are carefully followed. Use approved flexible gas connections or rigid piping, depending on provincial

and local codes, to attach burner to gas supply. Be sure to use proper size gas supply line. Carefully check all connections for gas leaks with soap and water solution.

Each installation must conform to all local, provincial and national codes. Refer to the national fuel gas code, local zoning and code authorities for details on installation requirements.

11.1 Existing Gas Supply

Before interrupting the existing gas supply it is recommended that the following be checked:

Shut down all gas appliances and carry out a pressure test to insure there are no existing leaks on the system.

Before connecting the appliance to the gas supply line, double-check that the appliance you have purchased is designed for the gas type you are using. The gas type markings are located on the certification label and also on the appliance’s gas valve.

Check the gas pressure to insure you will be able to supply the minimum inlet pressure for the appliance. Check your pipe sizing to insure that sufficient volume will be supplied to the appliance.

11.2 Gas Supply Installation

Provide adequate clearance for proper installation and checking of the gas connections.

Have your gas supplier or a qualified gas fitter run a gas supply line into the gas fireplace. The line must be properly sized and fitted according to the installation codes. Upstream of the appliance supply connection, the fitter shall provide an easily accessible manual shut-off valve.

The gas supply pipe should enter the appliance case through the opening at the rear left side. The supply pipe should be connected to the appliance gas inlet pipe situated at the left side of the control unit. Supply line connection to the inlet pipe is 3/8 NPT.

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 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.

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.

11.3 Pressure Testing 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 (3.5 kPa).

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 (3.5 kPa). Failure to do so will damage the appliance’s gas valve. Such damage is not covered by the manufacturer’s warranty.

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 the diagram to the right.

A built-in non-adjustable regulator controls the burner manifold pressure. The

correct pressure range is shown in the Specifications section of this manual. The pressure check should be made with the burner lit. See the lighting instructions section for full operating details.

BE SURE TO TIGHTEN THE PRESSURE TAP SET-SCREW AFTER CHECKING THE PRESSURE.

CHECK ALL GAS CONNECTIONS FOR GAS LEAKS.
