HOW IT WORKS
Following is a diagram showing the air ow
patterns for Model UEAS. Thin arrows show
air ow from combustion air intake, across the
burner, through primary and secondary heat
exchangers and out exhaust vent. Larger ar-
rows show air ow across the heat exchanger
to provide heat to the space.
● Horizontal or vertical combustion air/vent kit including concentric adapter
B
● Thermostat
● Thermostat guard with locking cover
● Vertical louvers
● Downturn nozzle kits
● Manual shutoff valves
B
Selection of either a horizontal or vertical combustion air/vent kit is required.
