13. 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.

14. ELECTRICAL AND THERMOSTAT WIRING
(SEE WIRING DIAGRAMS PAGES 19)

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.
