H− Condensate pH Range
The condensate is mildly acidic and can be measured with
pH indicators. The pH scale is a measurement of acidity
and alkalinity. The following scale shows the relative pH of
some common liquids as compared with condensate of
G61MPV units. The concentration of the acidity of all these
fluids including the condensate is very low and harmless.

I− High Altitude
NOTE − In Canada, certification for installations at eleva-
tions over 4500 feet (1372 m) is the jurisdiction of local au-
thorities.
The manifold pressure may require adjustment to ensure
proper operation at higher altitudes. Refer to tables 40, 41
and 42 for proper manifold pressure settings at varying alti-
tudes and required pressure switch changes and conver-
sion kits at varying altitudes.
The combustion air pressure switches are factory−set and
require no adjustment.
NOTE − A natural to L.P. propane gas changeover kit is nec-
essary to convert this unit. Refer to the changeover kit
installation instruction for the conversion procedure.
