Majestic lists the UD4 in the outside air components of the Biltmore SB60/SB80, Cottagewood and Designer DSR42 installation manuals. NYC does not allow new wood-burning fireplaces (Local Law 38 of 2015), so these parts are for installs outside the five boroughs.

  • Carries outside combustion air to the fireplace
  • Listed in the Biltmore SB60/SB80, Cottagewood and Designer DSR42 manuals
