Maintenance

Lubrication

The water pump motor and the combustion air blower are permanently lubricated and require no periodic maintenance. Auxiliary power vent motor (depending upon model) may or may not need periodic adjustment or lubrication. Consult power vent manual.

Vent System

Check the vent system annually for damage and/or obstruction. Any deformation of the vent system should be examined carefully to determine the cause of the deformation. The problem MUST be rectified and any damage to the vent system MUST be repaired.

Check Burner Flame Condition

When the burner is operating properly, the flame will appear to have a light orange base with a blue tint as you look through the burner observation window and across the burner surface (fig.8 ). Inspect the burner periodically through the observation window. If areas of the burner appear different or if the observation window is obscured, contact your authorized service agency to have the burner inspected for proper operation. If the burner is burning bright orange, red or white; it is too hot and will burn up igniters at an excessive rate. Call factory and/or authorized service company to adjust air shutter.

Piping and General Condition

Periodically inspect the booster heater for any signs of water leakage, combustion by- product leakage (soot, etc.), or wiring damage (electrical arcing, insulation damage). Contact your authorized service agency to correct any damage or improper operation that is discovered.

Check Air Filter

Regularly remove and inspect externally mounted air filter on the left side of booster. Filter is easily cleaned with soap and water. A clogged filter will restrict flow of combustion air which can lead to malfunction and internal damage. Damage caused by a blocked or clogged filter is not covered under the warranty.
