Before each use:
• Check the gas supply line for any possible leaks or damage.
• Check heater elements for debris. Visually check burner flames.
• Keep the heated area clear and free of combustible materials, gasoline and flammable vapors and
liquids. Ensure there is no obstruction of the flow of combustion and ventilation.
Periodic maintenance:
• Clean the heater with cleaning agents suitable for the unit’s construction material (i.e., stainless
steel cleaner).
• Inspect the gas supply piping system for signs of corrosion or failure. Replace if necessary.
Before conducting maintenance on the heater disconnect the power and gas supply. When pressure
testing the gas supply piping system follow these guidelines:
• At a test pressure in excess of 1/2 psi (3.5 kPa) the heater and ball shutoff valve must be
disconnected from the gas supply piping system during any pressure testing of the system.
• At a test pressure equal to or less than 1/2 psi (3.5 kPa) the heater must be isolated from the gas
supply piping system by closing it’s individual manual shutoff valve during any pressure testing of the
gas supply piping system.
Cleaning the main burner:
1 Use an air hose to blow any accumulated dust and/or dirt off the heater. Air hose pressure
should not exceed 30 psi.
2 Pass the air hose over the entire exposed area of the ceramic. A distance of 2’ to 4’ from the unit is
recommended.
3 Place the air hose outlet into the venturi tube and allow the air to flow for approximately one minute.
During long periods of non-usage, remove or cover heater with a polyethylene bag and shut off gas
supply. If further service to the heater is desired, contact your representative or the factory.

and gas supply. Disconnect power and gas supply to heater before servicing.
Burner malfunction may result in explosion or fire. Never operate the heater if there are any signs of
malfunction, excessive wear or damage. Call a professional for assistance.
NOTICE
Cleaning the heater elements with high pressure air may cause damage to the elements and equipment
failure. Do not blow out heating elements with high pressure air.
