HotJet USA Trailer Mounted Jetters Meet California Environmental Compliance

State of California regulations require that the equipment that we sell into or are operated in the state of California meet the Federal and California EPA requirements. This is a 3 step process.

Step 1. Engine Compliance

Step 2. Burner Registration

Step 3. Prop 65 Compliance

1. Engine Compliance

For (CARB) Cal Air Resource Board Compliance, we offer TWO POWER UNIT CHOICES:
(1) Either buy a system with a diesel powered engine or (2) Convert the 35HP engine to propane.

To meet the requirements for (CARB) Cal Air Resource Board Compliance, all gasoline powered equipment requires our exclusive LP Gas Upgrade for the engines. These engines still feature the same great power – EXCLUSIVELY ENGINEERED TO NOT LOSE POWER!

HotJet USA is the only supplier of this California certified conversion package.

Manufactured for the 23HP and 35HP engines, we have a FULL CONVERSION PACKAGE to run the equipment on LP GAS.

This upgrade is priced at $2,438.00 per unit.

Price includes 2 x 40 lb. propane tanks and holders (forklift size) and gives nearly 8 continuous hours of operation!!

NOTE: Our 29HP Kubota Diesel unit is FULLY COMPLIANT and needs NO MODIFICATIONS.

The HotJet 2 Diesel DOES NOT Require the CARB Conversion Kit.

Where to Find Propane Gas

Propane is available at Ace Hardware, UHaul, 7-11s, AmeriGas, as well as many other facilities around the state of California.

2. Burner Registration (for units that have a heater)


If the hot water equipment is to be operated in the following counties – SAN BERNARDINO, RIVERSIDE, LOS ANGELES, ORANGE – your burner must be registered with SoCal Air! To register your burner, fill out and submit FORM 222-PW found on the website here.


Operating the Hot Water Equipment Burner in Riverside, Los Angeles, San Bernardino and Orange Counties in California require registration with South Coast Air Quality Management District (SCAQMD). HotJet USA will provide forms for the registration. Registration cost is approximately $275.00 per year paid directly to the State of California.


Regulations within these counties require that diesel usage on the burner system not exceed 50 gl per day (of which our heater units do not use 50 gl/day). HotJet USA is NOT CHARGING for the required upgrades to the burner system, which is adding a dedicated non-resettable hour meter wired to the burner system.

3. Prop 65 Compliance

HotJet USA Power Plants are labeled with large Prop 65 Warning Labels. If labeling falls off due to wear, weather, etc. please contact us for replacements. We provide complete Prop 65 overview/compliance with every machine sold into or operated in the state of California.

For more information about California Prop 65 Compliance, visit our Prop 65 information page here.

Equipment Sign Off Sheets

All equipment sign off sheets and invoicing will reflect these compliance requirements.
