W A R N I N G !
Never use matches, candles, flames, or other sources of ignition to check for gas leaks.
C A U T I O N !
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 inhibit removal of covers or
service/maintenance or restrict access between the unit and walls or other units.

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, not 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.
