Owner’s Manual for Indirect Fired Heater

Introduction and Safety

Service Safety

DO NOT 

perform even routine service (oil/filter

changes, cleaning, etc.) unless all electrical com-
ponents are shut down.

Replace all missing and hard to read decals.
Decals provide important operating instructions
and warn of dangers and hazards.

Towing Safety

Towing a trailer requires care. The trailer and vehicle
must be in good condition and securely fastened to each
other to reduce the possibility of an accident. Some
states require that large trailers be registered and
licensed. Contact your local Department of Transporta-
tion (DOT) office to verify license requirements for your
particular unit.

Hitch and Coupling

Verify the hitch and coupling on the towing vehicle
are rated equal to, or greater than, the trailer’s
Gross Vehicle Weight Rating (GVWR).

Verify the trailer hitch and the coupling are compat-
ible. Verify the coupling is securely fastened to the
vehicle.

DO NOT

 tow the trailer using defective parts.

Inspect the hitch and coupling for wear or damage
before every tow.

To eliminate squeaking, wipe the coupler clean and
apply fresh grease each time the trailer is towed.

Connect safety chains in a crossing pattern under
the tongue.

Before towing the trailer, verify that the weight of
the trailer is equal across all tires. On trailers with
adjustable height hitches, adjust the angle of the
trailer tongue to keep the trailer as level as possi-
ble.

Verify all access doors on the trailer are closed and
locked.

Running Lights

Verify directional and brake lights on trailer are
connected and working properly.

Safe Towing Techniques

Practice turning, stopping, and backing up in an
area away from heavy traffic prior to transporting
the unit.

Maximum recommended speed for highway towing
is 45 mph (72 km/h). Recommended off-road tow-
ing speed is 10 mph (16 km/h) or less, depending
on terrain.

When towing, maintain extra space between vehi-
cles and avoid soft shoulders, curbs, and sudden
lane changes.

Reduce speed before curves, and maintain speed
throughout the curve.

Reduce speed before going over bumps or holes.
Keep your foot off the accelerator while going over
bumps or holes.

Reporting Trailer Safety Defects

If you believe your trailer has a defect which could cause

a crash, injury, or death, you should immediately inform

the National Highway Traffic Safety Administration

(NHTSA) in addition to notifying Generac Mobile Prod-

ucts, LLC.
If NHTSA receives similar complaints, it may open an

investigation. If it finds that a safety defect exists in a

group of vehicles, it may order a recall and remedy cam-

paign. However, NHTSA cannot become involved in an

individual problem between you, your dealer, or Generac

Mobile Products, LLC.
To contact NHTSA, you may either call the Auto Safety

Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-

9153), go to
