Gas Pressure Requirements and Checking
Two pressure taps for checking input and output gas pressures are located on the main gas valve. A qualified installer should
use this fitting for setting the correct gas pressure during initial installation.
The appliance and its appliance main gas 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 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping
system by closing its equipment shut -off valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
Drip Leg Requirement
A drip leg/ sediment trap must be installed within the main gas supply
line serving this appliance.
