Connect the RED wire from the jacketed cable
onto the common terminal of the gas pressure
switch. (See Figure I)
NOTE: If the distance between the power
venter and the gas pressure switch is
greater than the length of the cable, splice
a section of 2 conductor, PVC sheathed,
105º C thermostat cable to the supplied
cable. Make sure that the colored leads
remain consistent.
TROUBLE-SHOOTING, MAINTENANCE
AND TEST PROCEDURES
Vent System Maintenance
The vent system must be inspected at regular 3 month
intervals. Points of inspection are as follows:
1.
Screened opening of the vent hood should be
free from foreign material and cleaned as
necessary.
2.
Check all vent system connections for leak-
age and reseal where needed. If any vent
pipe shows signs of deterioration, replace
immediately and check new connections for
possible leaks. Reseal using RTV Red HiTemp
Silicone Sealer or equivalent.
Inspect proper closure of the back draft flapper
accessory, if used, and correct if it does not
close properly after use.
Gas Pressure Switch Test
1.
Follow the water heater operating instructions
to light the pilot / operate the heater.
2.
Open a hot water outlet. This should energize
the power vent system. Next close the hot
water outlet to de-energize the venter.
3.
Repeat step 2 to assure proper operation.
4.
If power venter does not energize, check that
the gas pressure switch tubes are properly
connected and that the tube ends are not
pinched closed.

IGURE
5.
Make sure pressure switch is mounted in such
a way that the diaphragm is oriented vertically.
Combustion Air Test
1.
Close all doors and windows of the building.
If the water heater is installed in a utility room
or closet, close the entrance door to this room.
Close fireplace dampers.
2.
Turn on any clothes dryers. Turn on all
exhaust fans, such as a range hood, bath
room exhaust fans and whole house fans, to
maximum speeds. (Do not turn on any fans
used strictly for summer exhausting).
3.
Open a hot water tap to full flow.
4.
Allow all fans and the water heater to operate
for five (5) minutes.
5.
Tripping of the spillage switch circuit (resulting
in shut down of the heater) during the 5 minute
operation indicates an unsafe operating condi-
tion. Turn off gas supply to water heater and
DO NOT OPERATE UNTIL UNSAFE VENTING
CONDITION IS INVESTIGATED BY A
PROFESSIONAL CONTRACTOR OR UTILITY
SERVICE PERSONNEL.
6.
Return all windows, doors and fans to their
previous condition of use.
