TESTING INSTALLATIONS FOR EFFICIENCY
A Draft gauge must be used. Draft in smoke pipe must
be set at .03 Water Column updraft. Failure to set
properly will cause fuel to be wasted, heating will not
be satisfactory, fast buildup of creosote in heat
exchanger and chimney may occur and cause damage
to your heating system.
The draft regulator will afford the user maximum fuel
efficiency, however, the finest draft regulator in the
world cannot increase the efficiency of a heating
system if the system as well as the regulator is not in
proper adjustment.
Basically, stack temperature and percentage of CO
2
are
a measure of stack losses for any fuel. Therefore,
many of the basic principles can be and should be
applied to oil-fired furnaces as well as for those burning
solid fuels.
In preparation for these tests, the following should be
checked. The Draft Regulator installed should be:
• plumb and level
• in the same room as the unit
• on the side of a vertical, sloping or horizontal smoke
pipe
• located close to the furnace
Drill two holes approximately 1/4 inch in diameter in the
flue pipe between the outlet from the furnace and the
Draft Control.
Insert a stack thermometer in one of the holes and
leave it there continually during the test so that you can
refer to it at any time. See Fig. 40
