Avoid locating the chimney termination in a
location susceptible to downdraft conditions, or near
ventilation inlets to the building.
When venting multiple appliances through one

All XL-3 heaters are equipped with two-stage
fuel units. This enables the heater to be connected
with a either a single pipe or a two pipe fuel supply
system. In locations where the fuel storage tank is
