HE Series Infrared Gas Heater Installation and Operation Manual
It is the responsibility of the installer to ensure correct gas connection. Confirm local require-
ments for gas connection with local authority.
Where allowed or required by local code, a flexible gas connector may be used. Refer and ad-
here to local code requirements and NFPA 54 Section 9.6 (in the USA).
If a flexible gas connector is used, it must be installed in the orientation shown in Figure 14 be-
low as required by approval standards and national installation codes. This orientation protects
the flexible gas connector from damage due to movement during heater expansion. Failure to
install the gas connector in the proper orientation can result in a hazardous condition, property
damage, personal injury or death.
