Cleaning Instructions
WARNING
Fire, Burn, and Explosion Hazard
■
This heater contains electrical and mechanical
components in the gas management, safety and
air
fl
ow systems.
■
Such components may become inoperative or
fail due to dust, dirt, wear, corrosive
environment, and aging.
■
Periodic cleaning and inspection as well as
proper maintenance are essential to avoid
serious injury or property damage.
1. Before cleaning, shut off all gas supply valves
and disconnect the electrical supply.
2. The heater should have dirt or dust removed
periodically:
a. Before each use give the heater a general
cleaning using compressed air or a soft brush
or dry rag on its case and internal
components. At this time, dust off the motor
case to prevent the motor from over-heating.
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 blade assembly. Additionally, make
sure the burner air inlet venturi ports and the
casting are free of dust accumulation.
WARNING
Do not use a pressure washer, water, or liquid
cleaning solution on any gas controls. Use of a
pressure washer, water, or liquid cleaning
solution on the control components can cause
severe personal injury or property damage due
to water and/or liquids:
■
In electrical components, and wires causing
electrical shock or equipment failure.
■
On gas control valves causing corrosion which
can result in gas leaks and
fi
re or explosion
from the leak.
Clean all components of the heater with
pressurized air, a dry brush, or a dry cloth.
