VENTING SYSTEM
HAVE VENTING SYSTEM CHECKED EVERY SIX MONTHS FOR
OBSTRUCTIONS AND/OR DETERIORATION IN VENT PIPING.
A. Insofar as is practical, close all doors, windows and air inlets
to the building. Turn on all exhaust fans (range hood,
bathroom exhaust, etc.) so they will operate at their maximum
speed. Close fireplace dampers.
B. Turn water temperature adjusting knob to full,
counterclockwise and open water faucet if necessary to keep
burner in operation.
C. “CHECKING THE DRAFT.” Operate the water heater for
several minutes and check to see if it is venting properly by
passing a lit match or paper near the opening of the Air Supply
Box. If the draft is proper, the match flame will be drawn into
the Air Supply Box (fig 11). If not, the combustion products
will tend to extinguish the flame. If an improper draft exists,
do not operate the water heater until proper adjustments or
repairs are made to provide adequate draft through the gas
vent.

D. Next, turn on all other fuel burning appliances within the same
room so they will operate at their full input.
Repeat step C above.
POWER VENTER MAINTENANCE
The FPSE-75 must be inspected quarterly. Points of inspection
are:
1. MOTOR - Motor must rotate freely. Oil every three months of
operation with 4 drops of SAE 20 oil, see fig. 12.
2. WHEEL - Wheel must be clean of soot, ash or any other
coating which inhibits either rotation or air flow. Remove all
foreign material from vent system before operating.
3. AIR SUPPLY BOX-Every month check operation and make
sure nothing is blocking dilution air entrance.
4. The pressure switch part inside the power venter must be
open and free from deposits of soot, carbon, etc.
For safety and satisfactory operation it is recommended that the
heater be checked once a year by a competent service person.
