Ideal Injector and Housing Kit LPG 38P 177374

The Ideal 177374 is an LPG injector and housing kit used on Ideal gas boilers. The injector is the calibrated orifice that meters gas into the burner, and it is held in a housing that locates it correctly in the gas train. Because the injector is sized for LPG rather than natural gas, it sets the gas input rate the burner sees and keeps combustion within the range the appliance was approved for.

It is an Ideal-manufactured component intended for the Logic Code Combi family and Ideal Commercial appliances. The kit is listed under part type INJECTORS and carries the alternative number 8901808.

• The burner fails to light, or lights and then drops out shortly after ignition.
• The flame is weak, uneven or visibly different from the normal pattern at the burner.

• The measured gas rate at the meter does not match the figure on the appliance data badge.

• Check the GC number and data badge on the appliance to confirm the correct LPG variant before ordering.
• The alternative number 8901808 may appear on older paperwork or parts listings for the same item.
