12. HEATER EXPANSION
Due to the characteristics of tube heaters, the installer must allow for 1” expansion for every 10’
length of tube. In order to address this characteristic, it is suggested that the gas line, flue vent,
and combustion air intake (if used) be installed in such a manner, that normal expansion of the
heater will be accommodated.

13. ELECTRICAL AND THERMOSTAT WIRING
(SEE WIRING DIAGRAMS PAGES 16 & 17)
Wiring must be done in accordance with local codes. The total load of all heaters must be
considered in determining the required contact rating of the controlling thermostat or switch.
