Cleaning Instructions
1. Before cleaning, shut off all gas supply valves and
disconnect the electrical supply.
2. The heater should have dir t or dust removed
periodically:
a. After each use, give the heater a general cleaning
using compressed air, a soft brush or dry rag on
its interior and exterior.
b. At least once a year, give the heater a thorough
cleaning. At this time, remove the fan and motor
assembly and brush or blow off the fan wheel,
giving attention to the individual fan blades and
also dust off the motor case to prevent the motor
from overheating and shutting the heater down.
Make sure the burner air inlet venturi ports and
the “throat” of the casting are free of dust
accumulation and the area between the heat
chamber top and inside case is also free of dust.
Additionally, the igniter should be removed,
cleaned, and its gap checked according to the
service instructions within this Owner’s Manual.
c. When cleaning, observe and obey the Warning
within these Cleaning Instructions. This same
Warning is also supplied on the heater.
WARNING
This heater must not be washed. Use of a pressure
washer, water or liquid cleaning solution on this heater
can cause severe personal injury or property damage
due to water and/or cleaning solution:
■
In electrical components, connections and wires
causing electrical shock or component failure.
■
On gas control valves causing corrosion which can
result in gas leaks and fire or explosion from the leak.
This heater must be cleaning in accordance with the
manufacturer’s instructions without being subjected to
liquid spray or wetting.
WARNING
Fire, Burn, and Explosion Hazard
■
This heater contains electrical and mechanical components in the gas management, safety and airflow systems.
■
Such components may become inoperative or fail due to dust, dirt, wear, and aging.
■
Periodic cleaning and inspection as well as proper maintenance are essential to avoid serious injury or property
damage.
1. The appliance area shall be kept clear and free from
combustible materials, gasoline, and other
flammable vapors and liquids.
2. Regulators can wear out and function improperly.
Have your gas supplier check the date codes on all
regulators installed and check delivery pressures to
the appliance to make sure that the regulator is
reliable.
3. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the
appliance.
