Rigid pipe connection:
The rigid pipe connection requires a combination of pipe fittings to obtain an in-line
connection to the range. The rigid pipe must be level with the range connection. All
strains must be removed from the supply and fuel lines so range will be level and in
line.
GAS PRESSURE REGULATOR
The gas pressure regulator supplied with this range must be used. The inlet pressure
to the regulator should be as follows for proper operation:
Natural gas:
Minimum pressure: 5" Water Column Pressure (WCP)
Maximum pressure: 14" WCP
LP gas:
Minimum pressure: 11" WCP
Maximum pressure: 14" WCP
Contact local gas supplier if you are not sure about the inlet pressure.
Burner Input Requirements
Input ratings shown on the model/serial rating plate are for elevations up to 2,000 ft
(609.6 m).
For elevations above 2,000 ft (609.6 m), ratings are reduced at a rate of 4% for each
1,000 ft (304.8 m) above sea level (not applicable for Canada).
GAS SUPPLY PRESSURE TESTING
Gas supply pressure for testing regulator must be at least 1" Water Column Pressure
(WCP) above the manifold pressure shown on the model/serial rating plate.
Line pressure testing above 0.5 psi gauge (14" WCP)
The range and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess
of 0.5 psi (3.5 kPa).
Line pressure testing at 0.5 psi gauge (14" WCP) or lower
The range must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 0.5 psi (3.5 kPa).
