HE+ Series Infrared Gas Heater Installation and Operation Manual
IMPORTANT SPECIAL NOTES: READ FIRST
1. Inputs 225 & 250 MBH: Special Tube Connection - Refer to Section 9.2, Fig 11
These input rates have an unpainted stainless steel first tube and second tube, and an
unpainted aluminized steel tube as the third tube; all subsequent tubes are hot rolled
steel. The first tube (stainless steel ) will “glow red” while heater is in operation - THIS
IS A NORMAL CONDITION
3. IF a 90° elbow is to be installed in the system, refer NOW to Section 7 and the Elbow
Kit installation instructions supplied with the kit
4. If a Torctite tube coupler is removed or loosened for any reason after the heater has
been put into service, the coupler must be replaced with a new one. A used, heated
coupler will not be able to be torqued properly for tight grip. Part Numbers: Aluminized
steel Torctite coupler: 906000117; Stainless steel Torctite coupler: 906000116.
