GAS SUPPLY INSTALLATION
7.1
Route the gas supply line to the appliance inlet connection
point (see figure 1).
Note: Pressure testing the line for leaks may need to be performed
before the line is connected to the appliance - see section 10.
7.2
Gas connection to the appliance is 3/8”NPT.
7.3
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.
7.4
Unions in gas lines should be of ground joint type.
7.5
The gas supply line must be sized and installed to provide a
supplyof gas sufficient to meet the maximum demand of
the appliance without undue loss of pressure.
7.6
Sealants used must be resistant to the action of all gas
constituents including LP gas. Sealants should be applied
lightly to male threads to ensure excess sealant does not
enter gas lines.
7.7
The supply line should include a manual shut-off valve to
allow the appliance to be disconnected for servicing.
7.8
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.
