Gas Supply Installation - Valor 530 Direct Vent Installation Manual

1. The appliance is supplied for supply gas connection at the rear left corner of the case. An adapter is included in the pack
that must be fitted to the appliance inlet pipe. Supply line connection to the adapter is
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. 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.
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. 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 67. A built-in non-adjustable 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 thermostat
at its highest setting. See lighting instruction section for
full operating details.
