5. GAS SUPPLY PIPING
Warning
NEVER USE MATCHES, CANDLES, FLAMES OR OTHER
SOURCES OF IGNITION TO CHECK FOR GAS LEAKS.
Warning
Many of the soaps used for gas pipe leak testing are
corrosive to metals. Therefore, piping must be rinsed
thoroughly with clean water after leak checks have been
completed.
NOTE
All gas piping must be arranged so that it does not interfere
with removal of any covers, inhibit service/maintenance, or
restrict access between the unit and walls, or another unit.
EPA and EPAW Boilers contain a 1 1/2 - 2 inch NPT gas inlet
connection on the back of the unit as shown in Figure***.
Prior to installation, all pipes should be de-burred and internally
cleared of any scale, metal chips or other foreign particles.
Do Not install any flexible connectors or unapproved gas
fittings. Piping must be supported from the floor, ceiling or
walls only and must not be supported by the unit.
A suitable piping compound, approved for use with natural
gas, should be used. Any excess must be wiped off to
prevent clogging of components.
To avoid unit damage when pressure testing gas piping,
isolate the unit from the gas supply piping. At no time should
the gas pressure applied to the unit exceed the factory
specified pressure. Leak test all external piping thoroughly
using a soap and water solution or suitable equivalent. The
gas piping used must meet all applicable codes.
5.1 Manual Gas Shutoff Valve
A manual shut-off valve must be installed in the gas supply
line upstream of the boiler as shown in Figure 2-7.
