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.
