The V-belt driving the air pump requires no servicing and no preservatives
or dressing compounds should be used. Belts normally stretch with use and
proper tension should be maintained. Do not apply excessive tension. The
air pump can be moved the small distance necessary for belt adjustment
without any change of piping.
On a combination fired unit it is an acceptable practice to remove the belt
when gas is being used for extended periods. It is not absolutely necessary
to do this - however, pump and belt life will be extended if the belt is
removed.
