What it is

The Ideal 173388 is a base frame supplied as a casing assembly for 7-section Fd33 commercial boilers. It forms the lower structural mounting for the heat exchanger and casing on Ideal Commercial Harrier appliances, holding the sections and the surrounding panels in correct alignment. As a load-bearing component it also carries the weight of the boiler assembly and keeps the gas train and flue connections sitting square.

Signs this part needs replacing

  • Visible corrosion or pitting along the frame where condensate or spillage has collected
  • Cracking, bending or distortion of the frame after handling or transport damage
  • Boiler casing panels no longer sitting flush or square because the base has moved
  • Heat exchanger sections or mounting points showing movement against the frame
  • Difficulty aligning the gas train or flue connections during service work

Before you order

  • Confirm the appliance model and section count against the compatibility list, as the frame is specific to the 7-section Fd33 build
  • Check the existing part number on the boiler against 173388, 1179423 and 85537063 before ordering
  • Inspect the base gasket and any sealing strips at the same time, as these are normally disturbed when the frame is removed
