WARNING

Maintenance

Always wear clothing that protects the

body and use protective glasses when

maintaining the heater.

Electrical shock or explosion may occur

when conducting maintenance while

the heater is connected to the power

source 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.

Before each use:

• Check the gas supply line and hose assembly 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 materials (i.e., stainless steel

cleaner).

• Lubricate moving parts.

• Inspect the gas supply piping system for signs of

corrosion or failure. Replace if necessary.

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.

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 psig (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 psig (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. Gently use an air hose to blow any accumulated

dust and/or dirt off the heater. Air hose pressure

should not exceed 30 psig.

2. Gently, pass the air hose over the entire exposed

area of the ceramic. A distance of 2’ to 4’ from

the unit is recommended.

3. Gently 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.
