14. 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.
