 2.9  GAS SUPPLY PIPING 

AERCO

’s  Benchmark  Gas  Components  and  Supply  Design  Guide,  TAG-0047  (GF-2030) 

must be consulted prior to designing or installing any gas supply piping. 

 WARNING! 

Never use matches, candles, flames or other sources of ignition to check for gas leaks

 

 CAUTION! 

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.

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, the unit must be isolated from the gas 
supply  piping.  A thorough  leak test  of  all  external  piping  must  be  performed  using  a soap  and 
water solution or suitable equivalent. The gas piping used must meet all applicable codes. 

2.9.1  Gas Supply Specifications  

AERCO  Benchmark  Low  NOx  series  boilers  require  a  stable  natural  gas  and  propane  input 
pressure. It must comply with the allowable gas inlet pressure range specified in the 

Benchmark 

Pre-Installation Gas Supply Guide

 (TAG-0047, GF-2030).  

2.9.2  External Gas Supply Regulator 

An  external  gas  pressure  regulator  is  required  on  the  gas  inlet  piping  under  most  conditions 
(see,  below).  Regulators  must  conform  to  the  specifications  in  the 

Benchmark  Pre-Installation 

Gas Supply Guide

 (TAG-0047, GF-2030).
