The heater and its gas connection must be leak
tested before placing the booster heater in
operation.
The booster heater and its individual shut-off
valve must be disconnected and isolated from
the gas supply piping system during any
pressure testing of the system at test
pressures in excess of 1/2 PSI (3.5 kPa.).
This appliance 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 1/2 psig 
(3.5 kPa).
Dissipate test pressure from the gas supply
line before re-connecting the heater and its
manual shut-off cock to the gas supply line.
