Gas piping pressure test
When performing the gas piping pressure test, ensure the following requirements are
met.
WARNING
Never check for gas leaks with an
open flame.

Exposing boiler gas pressure
regulator and gas valve to extreme
pressures renders warranty null and
void.
IMPORTANT
½ psig = 14 "w.c.
Boiler Connections
1. Isolate the boiler from the gas supply
piping system using the individual
manual shutoff valve during pressure
tests equal to or less than ½ psig/
14 "w.c.
2. The boiler 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
½ psig/14 "w.c.
3. Perform leak test.
Use approved liquid spray solution
for bubble test. Ensure that no liquid
is sprayed on any electrical
components, wires or connectors.
Do not allow leak detection fluid to
contact gas valve regulator or
regulator vent opening.
