Summerset Sizzler Series Natural Gas Regulator - 12108 (REG-SIZ-NG)

Summerset Sizzler Series Natural Gas Regulator

This is the natural gas appliance regulator that threads onto the inlet of the grill manifold and holds gas pressure steady for the burners. It is used only on natural gas models. The same part appears in the parts lists for earlier Sizzler grills and for the current Sizzler, Sizzler Pro and TRL Pro lines.

Check Your Grill’s Compatibility

Before You Order

Check the rating plate to confirm your grill is set up for natural gas. Propane grills use an LP regulator with hose instead, and the regulator may look different from your original. Have gas connections leak-tested after installing.

Not Sure Which Summerset Grill You Have?

Finding your Summerset model and serial number is easy.

Summerset model numbers look like SIZ32, TRL38 or SZRPRO40. The series, the size and the gas type all change which part fits.

1

Find the rating plate. It lists the model, the gas type and the serial number.

2

On Summerset grills it is on the outside of the firebox (grill basin), and on some models it is also on the underside of the drip tray.

3

No luck? The model number is on the front of your owner’s manual.
