Ideal Orifice Kit 7.8 60kW 176370

The Ideal 176370 is an orifice kit sized at 7.8 and specified for 60kW appliances in the Ideal commercial range. The orifice sits in the gas train and meters the gas passing through to the burner, so its bore size directly affects the input rate and combustion quality of the appliance.

It is supplied as a kit of orifice and associated parts, and is listed by Ideal under the injector group of spares. Correct sizing matters: an orifice of the wrong rating will shift the gas input away from the appliance's design figure.

• Gas input rate measured at the meter falls outside the figure stated for the appliance
• Combustion readings drift from the commissioned values, with CO or CO2 outside the expected band
• Unstable or lifting flame at the burner, or difficulty holding a steady flame picture
• Sooting, discolouration or heat damage around the burner area
• An orifice that is blocked, corroded or visibly damaged on inspection

• Confirm the appliance model and GC number against the compatibility list, as the 7.8 orifice is specific to 60kW units
• Note the alternative number 1782260 when cross-referencing an existing part or an older order record
• Check whether the burner gasket or seal needs renewing at the same time, since the gas train has to be opened to reach the orifice
