B. SERVICE AND MAINTENANCE
INSTRUCTIONS
B.1 SERVICING INSTRUCTIONS
Under normal working conditions, it is recommended that the Ultimate Products
Heater should be serviced annually. In exceptionally dirty or dusty conditions
such as may occur in a foundry, more frequent servicing may be desirable.
Servicing work should be carried out by a qualified gas service engineer.
IMPORTANT:
1. Never rest anything, especially ladders, against the heater.
2. Turn off gas and electrical supplies before servicing or repair work is
started.
3. Unless otherwise instructed, reassemble parts in reverse order to the
following instructions.
B.2 ROUTINE SERVICE
A. FAN – Inspect the main fan propeller and remove any dust brushing with a
soft brush. Similarly remove any dust from the finger guard covering the
secondary (cooling) impeller and the mesh aperture in the motor cover. Ensure
that the impeller turns
freely and that there is not excessive play in the bearings.
B. EMITTER TUBE – Brush away any dust on the exterior of the emitter tube.
Inspect the emitter tube internally by removing the burner control box as directed
in “D” below. If there is any appreciable build up of dust or deposits, the tube
should be cleaned internally. The emitter tube may be cleaned by use of an
industrial vacuum cleaner with a long extension tube, which is passed down the
emitter tube.
Replace the burner/control assemblies engaging them fully on their tubes and
secure by tightening the screws ensuring that they are squarely positioned (i.e.
with the air inlet cover plate facing upwards).
C. REFLECTOR – The condition of the reflector should be noted and any
necessary cleaning performed. The reflectors can be simply removed for
cleaning by removing the reflector clamp screws securing them to the
suspension brackets and sliding them out of the suspension brackets. The
reflector can be cleaned with a soft cloth and detergent in water.
A mild non-abrasive metal polish may be used in cases of extreme discoloration.
D. REMOVAL OF BURNER/CONTROL ASSEMBLY – Remove the burner/
control assembly by disconnecting the gas and electrical supply (and fresh air
inlet duct if fitted). Slacken the burner fixing screws and draw the assembly off
the emitter tube.
