Deterioration of the front grille
SUNPAK heaters must be installed in such a
manner as to allow the products of
combustion or hot gases to vent out the top
portion of the heater. When operating
normally, only radiant heat passes through
the front grille. If conditions exist which force
hot gases through the front grille of the
heater, the installation must be altered to
correct the condition.
