THE DIP-1 FAN PROVING SWITCH
This device MUST be installed by a qualified installer in accordance with the manufacturer's instalation instructions.
In the USA wiring MUST be in accordance with the NFPA 70 National Electrical Code and applicable local codes.
In Canada wiring MUST be in accordance with C22.1 Canadian Electrical Code and any other fedral, provincial, local
code requirement and appliance manufacturer's instructions.
WARNING: Disconnect electrical power supply when wiring pressure switch.
INSTALLATION PROCEDURE FOR REMOTE PRESSURE SWITCH KIT:
1. The pressure switch must be mounted in the vertical position to maintain maximum sensitivity and removed
from any heat source. (See Figure 19)
2. Attach ¼" tubing to the pressure sensing fitting with the ¼" compression nut and sleeve. Then route tubing to
power vent and connect end to pressure sensing tube on the power vent.
NOTE 1:
Use ¼" metal, ¼" Nylon tubing rated to SAE J844 or equivalent plastic tubing rated for applications of 150°F
.
or higher
NOTE 2:
Secure routed tubing in position away from any heat sources.
WIRING
Wire in accordance with the Appliance Manufacturer's installation instructions, the National Electrical Code and applicable
local codes (see Wiring Diagram and Page 8). In Canada in accordance with C22.1 Canadian Electrical Code Part 1 and
any other applicable fedral, provincial, local code requirement and appliance manufacturer's instructions.
SETTING PRESSURE SWITCH
Follow appliance manufacturer's instructions, light the appliance and after the appliance has operated a sufficient time to
establish stable combustion, adjust pressure switch sensitivity by turning pressure switch adjustment screw "clockwise"
(See Figure 19) until burner feed operation stops. Then turn the adjustment screw "counter-clockwise" until burner feed
starts operating. Turn the adjustment screw an additional ¼ to ¾ of turn "counter-clockwise" more to ensure adequate
switch adjustment. See page 8.
SYSTEM CHECK-OUT PROCEDURE FOR FAN PROVING SWITCH
1. Adjust the draft according to Air Flow Adjustments and DIP-1 Draft Inducer Proving Switch Adjustments.
2. After the appliance has operated for a sufficient time to establish stable combustion.
3. Check the set point of the pressure switch adjustment by rotating the switch adjustment screw "clockwise"
until the burner feed operation stops, then rotate the switch adjustment screw "counter-clockwise" until the
burner feed operation starts. Add an additional ¼ to ¾ of a turn "counter-clockwise" to ensure a proper
setting.
4. Remove the ¼" sensing tube from the pressure switch, the burner feed operation MUST stop. Reconnect the
¼" sensing tube and the burner feed operation will start operating.
5. Readjust the RC Draft Control barometric damper and/or the appliance draft controls to provide the normal
operating draft recommended by the appliance instructions and markings.
WARNING: If for any reason the system has shut down during operation, the cause of the system failure should
be investigated and corrected before re-setting the safety controls and re-starting the system.
