A sediment trap may be upstream of the heater to prevent
moisture and contaminants from passing through trap to
the heater controls and burners. Failure to do so could
prevent the heater from operating reliably. Consult appli-
cable codes.
An external regulator must be used on all propane/L.P.G.
heaters, in addition to the regulator fitted to the heater, to
reduce the supply tank pressure to 13" w.c. (maximum).
Any copper tubing used to supply propane / L.P.G. from
the tank must be internally tinned.
